What is Mineral Alkaline Water?

Bewinch uses innovative natural mineralization technology, adding natural mineral filter media inside the filter. Tap water first passes through multi-stage filtration to become pure water, then undergoes deep mineralization. The output is like spring water at around pH7.6, rich in calcium, magnesium, sodium, potassium, zinc, metasilicic acid and other beneficial minerals — smooth, mellow, and subtly sweet.

Mineralization uses deep ore from 1,000–2,000 meters underground, yielding weak alkalinity around pH7.6. Ice made from it is crystal clear and neutralizes acidity in drinks — ideal for coffee, tea, and juice, softening the astringency of tannins for a rounder mouthfeel.

Core Parameters

Filter Information

The G7s Wanxiang uses three independent filters. When one reaches end of life, replace only that one. Spin ID感应 technology auto-detects and resets when a new filter is inserted.

Filter life is not fixed; it depends on local water quality, daily usage, working pressure, inlet temperature, and power-on hours. In regions with high raw TDS (e.g., parts of Shandong, Hebei, Inner Mongolia, Xinjiang, Ningxia), filters may decay faster — this is normal. The screen shows smart filter-replacement reminders. Unopened filter media has a 5-year shelf life; store in a cool, dry place.

Energy & Environment

The G7s is an instant-heat countertop unit with short heating/dispensing times. With AI dynamic waste ratio and Grade-1 efficiency, daily use saves water and power. If idle for over 72 hours, before reuse drain all water, replace raw water, and repeat purification-and-drain 3 times to ensure fresh output.

Unboxing & Package Contents

After unboxing, check the accessory list and inspect the unit for shipping damage or scratches. Remove protective film from the raw tank, purified tank, brewing pitcher, and other parts.

After unboxing, simply place the brewing pitcher and purified tank — installation is very easy. If any accessory is missing or the unit is damaged, contact the store where you purchased promptly.

Placement & Installation Guide

Countertop, No-Installation Placement

The G7s Wanxiang is a countertop no-installation purifier. Just add tap water and use — no plumbing, no professional installation. Note the following when placing:

1. Place on a stable, firm, level surface; avoid direct sunlight, humid environments, and heavy oil-fume areas.

2. Leave ventilation space around the unit; do not press the back or sides tightly against walls or cabinet doors.

3. Place near a grounded 220V/50Hz three-prong outlet; the cord must not be pulled or compressed.

4. The surface must support the full weight of the unit plus water; avoid edges where it could slip.

5. If using expansion modules, pull out the MixHub dock on the right side of the host, align the module, and push in — connection completes in ~5 seconds.

Pre-Power-Up Check

1. Confirm all three filters are correctly twisted and locked; purified and raw tanks are seated.

2. Fill the raw tank with standard municipal tap water (5°C–35°C) to the max line.

3. Confirm the brewing pitcher bottom is dry before placing on the host.

4. Confirm voltage matches the rating plate before plugging in.

New-Unit Flushing Guide

Before first use, follow these steps to activate filters and clean water lines. The whole process takes about 30–40 minutes.

Step 1: Unbox & Air Out

Remove the unit and all accessories from the box. Take out the raw tank, top cover, and purified tank. Air the unit in a cool, ventilated place for 12–24 hours. If you purchased modules, take those out too and air them together.

The unit and filters may carry a slight odor from the factory; please complete the flushing process carefully. Adjust airing time based on actual odor.

Step 2: Power On & Purify

Fill the raw tank with standard municipal tap water to the max line. Reinstall top cover, purified tank, and raw tank in order. Plug in and start purification. A water-drop purification icon appears on the display; wait ~10 minutes until the pump stops, the purified-water level light goes out, and purification completes.

Step 3: Ambient-Water Drain Flush (repeat 3–5 times)

Place a container larger than 3.5L under the right spout. Long-press "Dispense/Stop" for ~5 seconds until a beep enters drain mode. During draining, the purified-water level light flashes and gradually empties; the unit drains continuously and auto-stops when done. After draining, remove the raw tank, pour out waste water, refill, and purify again.

Step 4: 45°C Warm-Water Flush (repeat 1–2 times)

Fill the raw tank and reinstall; wait for purification to complete. Place a heat-resistant container (>3.5L) under the right spout. Tap the screen to select 45°C, press "Dispense/Stop" once; the red dispense light comes on. Dispense 45°C water until the unit auto-stops.

Step 5: 98°C Hot-Water Flush (repeat 1–2 times)

Fill the raw tank and reinstall; wait for purification. Place a heat-resistant container (>3.5L) under the spout. Select 98°C on screen, press "Dispense/Stop" once; red light on. Dispense 98°C water until auto-stop. Beware of hot-water splashing.

Step 6: Tea-Line Flush (repeat 1–2 times)

Place the cleaned brewing pitcher on the machine (ensure bottom is dry). Press "Brew/Stop"; the unit auto-fills and heats. When heating completes, pour out the water in the pitcher — tea-line flush done.

Video tutorial: https://www.bilibili.com/video/BV1auaAzdEGN/

Step 7: New-Unit Hot-Water Calibration

On first hot-water use, the unit calibrates output temperature and heating program based on ambient and inlet water temperature. After flushing, wait for the tank to refill, then dispense 98°C water for 1–2 minutes continuously, then 85°C for 1–2 minutes, repeating across different temperatures down through the 45°C level — this lets the unit fully adapt to current ambient temperature.

In high-altitude areas, perform a boiling-point detection first per the manual to avoid steam or hot-water splashing during heating. Above 1,500m altitude, do not dispense 98°C hot water to avoid steam blow-out.

White Misty Cloudiness in New Tank? — White Mist / Bubbles Explained

This "cloudiness" is not impurities or harmful substances in the water — it is dense tiny bubbles formed by air dissolved in the water. Because Bewinch uses RO reverse osmosis with 0.1-nanometer filtration precision, water molecules cannot pass the RO membrane under natural water pressure, so the built-in booster pump pressurizes the tap water to squeeze water molecules through the membrane.

During pump operation, air in the water is highly compressed, forming many dense bubbles. This is a normal physical phenomenon and does not affect water quality — it is safe to drink. After multiple flushes, as air in the internal filters and lines decreases, this effect weakens noticeably. On first dispensing of purified water, white foam may also appear in the container — same fine bubbles, which disappear on standing.

Use in High-Altitude Areas: Boiling-Point Detection & Adjustment

At high altitude, lower air pressure means water boils below 100°C. We recommend a manual boiling-point detection before use:

1. Place the brewing pitcher (empty) on the machine.

2. When the purified tank is full, long-press "Brew/Stop" on the display for 5 seconds to fill the pitcher; the pitcher starts heating to detect the boiling point.

3. When detection completes, the unit beeps three times and enters standby.

Above 1,500m altitude, do not dispense 98°C hot water to avoid steam blow-out and scalding.

Dispensing: Ambient / Hot Water

1. When the purified-water level icon shows more than one bar, press "Dispense/Stop" to get ambient-temperature water.

2. For hot water, tap any of the 45°C / 55°C / 65°C / 75°C / 85°C / 98°C icons; the selected icon flashes.

3. Press "Dispense/Stop" again to dispense hot water.

4. Press "Dispense/Stop" once more to stop dispensing.

The spout lights blue for ambient water, red for hot water, and green for draining — easy to tell at a glance.

Fixed-Volume Dispensing

Tap the volume "+" / "-" buttons to select 200 / 300 / 500 / 60 / 90 / 120 mL. Within 10 seconds of selecting the volume, press "Dispense/Stop" and the unit starts dispensing. After selecting volume, tap temperature to choose 45 / 55 / 65 / 75 / 85 / 98°C.

Example — 65°C, 120 mL: tap the 65°C icon (flashes), tap volume until 120 mL shows, then tap "Dispense/Stop" to dispense at that temperature and volume.

Drain Operation

Long-press "Dispense/Stop" for 5 seconds until a beep enters drain mode. Only the purified-water level light flashes and the green drain light is on; water exits the right spout. When the purified tank empties, draining auto-stops. You can also press "Dispense/Stop" to stop draining.

Brewing: One-Tap Tea Brewing

1. Place the tea to be brewed in the tea basket; put the basket into the brewing pitcher and seat it.

2. Tap any tea icon: floral/fruit tea, fermented tea, herbal, or water boil.

3. After selecting a tea icon, the unit offers a default brewing time; to adjust, use the custom-brew key to set heating time.

4. Select "Brew/Stop"; the unit fills the pitcher to 500 mL (max pitcher level) then starts heating.

5. When brewing time completes, it auto-switches to keep-warm; the pitcher enters keep-warm mode showing remaining time.

Total tea-water volume in the pitcher must not exceed 500 mL; water boiling must not exceed 700 mL — to avoid overflow scalding or water entering the pitcher base. Do not fill the pitcher above the max line to prevent boiling-water blow-out.

Reheat & Keep-Warm

Tap the desired tea icon or temperature icon, then press "Reheat" to reheat the tea in the pitcher. The reheat level must be higher than the current tea temperature; if lower, the heating program will not start.

Long-press "Reheat" for 5 seconds to toggle keep-warm. Use custom-brew "+" / "-" to adjust keep-warm time (5–120 min) and heating time (1–30 min).

Smart Features: Smart Child Lock

Long-press "Child Lock" for 5 seconds to enable child-lock mode; the child-lock icon lights. No touch, dispense, or heating operation is possible. Short-press child-lock once to unlock for a single dispense; after 10 seconds of inactivity it re-locks. Long-press 5 seconds again to cancel child lock.

On a new unit or after a power-cycle reboot, child lock is off by default and must be enabled manually.

Water Custom / Tea Custom

Water Custom (1 set): Select the desired volume and temperature icons on the display, then long-press "Water Custom/Clean" for 3 seconds until a beep confirms the custom data. To dispense, press "Water Custom/Clean" then "Dispense/Stop" — it dispenses at the set temperature and volume.

Tea Custom (2 sets): Select tea icon, volume, and heating time, then long-press "Tea Custom I" or "Tea Custom II" for 5 seconds until a beep confirms. To brew, press the corresponding tea-custom icon then "Brew/Stop" — it brews with the set parameters.

Repeat to overwrite custom data. On a new unit or after reboot, no custom data is set. To prevent dry boiling from low volume, the set volume defaults to 200 mL if set below 200 mL.

ECO Eco Mode

When idle for a long time, the display dims; tap any button or icon to fully light it. Long-press the "55°C" icon for 5+ seconds until "ECO" shows at the raw-TDS position — eco mode on. This turns off the raw-tank ambient light and auto keep-warm. Long-press 5 seconds again to restore normal mode.

Full-Unit Self-Clean

Without tapping any dispense temperature or volume button, long-press "Water Custom/Clean" for 3 seconds to enter clean mode. The unit dispenses 150 mL of 98°C hot water from the spout. The spout lights red during cleaning.

TDS Water-Quality Display

The screen shows raw-water TDS and purified-water TDS in real time. TDS (total dissolved solids) is the total of inorganic salts and heavy metals dissolved in water. Raw TDS = value before filtration; purified TDS = value after filtration.

TDS is only one common indicator of water quality before/after purification; it cannot absolutely represent water quality. It is normal for readings to fluctuate by range based on water quality and environment.

Raw-Tank Ambient Light & TDS Alarm

Based on raw TDS, the unit shows red or ice-blue ambient light during purification: red when raw TDS ≥150, blue when <150.

When raw TDS exceeds 999, raw TDS shows 999, the buzzer sounds, the raw-water shortage light comes on, and the raw-tank ambient light flashes. Long-press the "75°C" temperature icon for 5 seconds to cancel the alarm (shows "AL"); long-press again to restore (shows "UAL").

Temperature Presets & Recommended Uses

The spout lights blue for ambient, red for hot, green for draining — instant visual distinction. Above 1,500m altitude, do not dispense 98°C hot water to avoid steam scalding.

Filter Structure & Life

The G7s Wanxiang uses three independent filters. When one reaches end of life, replace only that one. The screen filter-life indicators 1, 2, 3 represent the three stages; each has 3 bars — more bars lit means more remaining life. When all 3 bars are dark for an indicator, that filter is at end of life and needs replacement.

When a filter-life indicator drops from 3 bars to 0, the unit beeps 3 times at each dispense — it is time to replace. Actual filter life depends on power-on hours after activation, local water quality, and daily dispensing volume. The screen indicator is the authoritative guide.

Filter Replacement & Reset: Spin ID感应 Reset

1. Turn off power; lift the purified tank; lift the top cover from the inner groove.

2. Grip the handle on top of a filter; turn the indicator from "Lock" to "Unlock"; lift the filter out to remove it.

3. Align the new filter's indicator to "Unlock" and insert into the corresponding slot; grip the handle and turn from "Unlock" to "Lock".

4. Power on; within ~1 minute the corresponding filter-life indicator refills to full bars — reset complete.

5. After replacement, do 3 ambient-water drain flushes to fully wet the new filter.

Replacement Notes

1. Replace filters promptly; otherwise core components may be damaged.

2. If the filter sensor light does not change within 60 seconds of inserting, pull out and re-insert, trying several times until it auto-resets.

3. Do not insert/remove filters during purification — this may cause air trapping and malfunction.

4. Each filter chip can only reset its corresponding filter once; wait for the life-monitoring system to prompt replacement before resetting.

5. After installing a new filter, repeat drain operation 3 times to fully saturate the filter.

Please use Bewinch original filters. Non-original accessories may cause substandard water quality or machine malfunction. Damage from non-genuine filters is not covered by warranty.

Daily Cleaning: Purified Tank Washing

1. After draining, unplug the power; lift the purified tank; lay it flat and release the latches on both sides of the lid.

2. Use a soft cloth (boiled and cleaned) to wipe the inner surfaces of the tank and lid.

3. After cleaning, close the lid and latch it; reinstall the purified tank and press down to seat.

4. Plug in; when the tank refills, enter drain mode and drain, repeating 2–3 times.

We recommend cleaning the purified tank every 1–2 months. The tank has a built-in Helix UV lamp; do not power off during daily use.

Brewing Pitcher Cleaning & Descaling

1. Remove the brewing pitcher from the machine; after cooling, hold the handle with one hand and grip the inner lid with the other, lifting up.

2. Grip the lid with one hand and the inner lid with the other; rotate counterclockwise until the arrow turns from locked to unlocked, then lift out.

3. Remove the metal tea basket downward; wash the pitcher interior, inner lid, lid, and tea basket with warm water.

Descaling: Use white vinegar — pour an appropriate amount into the pitcher, let sit 1 hour, empty, then rinse 5–6 times with clean water. Or use citric acid — pour in hot water, add 6.5g citric acid or baking soda, let sit 15 minutes, empty, rinse 5–6 times.

Never immerse the pitcher body in any liquid. When returning it to the machine, ensure the bottom is dry with no residual water.

Drip Tray Cleaning

During use, remove the drip-tray assembly in the direction shown in the diagram and promptly clear accumulated water.

Body Care

For daily cleaning, wipe with a soft dry cloth; avoid corrosive cleaners or hard scouring pads. Place the unit away from direct sunlight, humidity, and oil fumes. If idle for over 72 hours, before reuse power on and drain all internal water, replace raw water, wait for the purified tank to refill, then drain again — repeat 3 times.

Waste-Water Explanation: Ratio & Handling

Bewinch's settling-type float magnetic-sensing waste stratification structure uses a diversion column and float magnetic water-level monitoring to stably hold the waste ratio around 3:1. With AI dynamic waste-ratio monitoring, the purer the raw water, the less waste — down to 4:1.

The remaining water in the raw tank is not true "waste water" — it is just concentrated water with higher salt content. When the unit prompts for raw-water replacement, pour out the concentrated water and refill with fresh raw water. The concentrated waste water can be reused for cleaning, watering, mopping, or toilet flushing — no waste.

Deep Cleaning & Descaling: Daily Cleaning Schedule

Body: Wipe the shell and touch screen daily with a soft dry or slightly damp cloth; avoid corrosive cleaners and hard pads.

Purified tank: Remove and wash inner surfaces and lid every 1–2 months.

Drip tray: Remove, empty, and rinse promptly.

Brewing pitcher / glass stewing pot: Empty tea after each use; disassemble and wash after cooling.

Pitcher & Line Descaling

After long use, scale may form on the pitcher interior and heating plate; we recommend descaling every 3–6 months:

Method 1 (white vinegar): pour vinegar into the pitcher, let sit ~1 hour, empty, rinse 5–6 times.

Method 2 (citric acid / baking soda): pour in hot water, add ~6.5g citric acid or baking soda, let sit ~15 minutes, empty, rinse 5–6 times.

The unit's "Water Custom/Clean" self-clean mode dispenses 98°C hot water to flush lines; pair with regular water changes to keep lines clean.

Never immerse the pitcher or whole unit in liquid; wipe dry the bottom before returning to the host.

Expansion Module Cleaning (if equipped)

The ice module's open ice bin can be periodically removed and washed; it has a drain outlet at the bottom. The slush module's electric shaved-ice cup can be detached and washed. The sparkling module bottle should not hold liquids other than purified water and must not be heat-washed or put in a dishwasher. For modules not in use, flush with water and air-dry internal lines before storage to avoid moisture and bacterial growth.

Water Quality Questions

White foam in the water?

White foam is normal — it is fine bubbles that disappear on standing; safe to drink. Two causes:

① Pressure change: during purification, the booster pump pressurizes water through the filter membrane; some air dissolves under pressure. When dispensing, pressure releases and dissolved air expands into fine bubbles.

② Temperature change: warmer water dissolves more air; as hot water cools, dissolved air comes out as fine bubbles.

What is mineral alkaline water?

Bewinch uses innovative natural mineralization, adding natural mineral media to the filter. Tap water first passes multi-stage filtration to pure water, then deep mineralization — output like spring water at ~pH7.6, rich in calcium, magnesium, sodium, potassium, zinc, metasilicic acid — smooth and subtly sweet.

Purified TDS stays unchanged?

If purified TDS stays the same, the raw water may not have been changed. Replace all raw water and re-purify. TDS is only one common water-quality indicator; range fluctuation based on water quality and environment is normal.

Operation Questions

How do I use the smart child lock?

Long-press "Child Lock" for 5 seconds to enable; no touch/dispense/heating operation is possible. Short-press once to unlock for a single dispense; it re-locks after 10 seconds idle. Long-press 5 seconds again to cancel.

How do I set water custom and tea custom?

Water custom: select volume and temperature icons, long-press "Water Custom/Clean" for 3 seconds to save. To dispense, press "Water Custom/Clean" then "Dispense/Stop".

Tea custom: select tea icon, volume, and heating time, long-press "Tea Custom I" or "Tea Custom II" for 5 seconds to save. To brew, press the tea-custom icon then "Brew/Stop".

On a new unit or after reboot, no custom data is set. To prevent dry boiling, volume set below 200 mL defaults to 200 mL.

What if I haven't dispensed in 12 hours?

If 12 hours have passed without dispensing, we recommend first dispensing 98°C hot water for 5 seconds to flush standing water from lines, ensuring drinking safety. The purified tank has a built-in UV lamp; do not power off during daily use.

Can I pour hot water into the tank?

Never pour hot water into the raw tank — it will deform the tank and prevent normal use. Do not pour sewage, beverages, or non-tap water into the tank, as this will affect filter life or clog lines/filters. Use municipal tap water at 5°C–35°C.

Filter Questions

Why does filter life deplete quickly?

Actual filter life depends on power-on hours after activation, local water quality, and daily dispensing volume. Each filter has a rated purified-water volume; heavy daily use and poor raw water both shorten life. In high-TDS regions, filters may decay faster — this is normal.

What happens if I don't replace filters on time?

Filtration weakens with use; harmful impurities on the membrane approach saturation, reducing purification capacity. The unit alarms when filters are due. Delaying replacement may let bacterial impurities on the membrane enter drinking water (secondary contamination) and increase clogging risk for other filters or the unit.

How often should filters be replaced?

The G7s Wanxiang uses three composite filters: Stage 1 PP composite and Stage 3 mineral composite are recommended every 6–8 months; Stage 2 RO membrane every 2–3 years. Actual life depends on power-on hours after activation, local TDS, and daily dispensing volume. The unit gives smart reminders based on usage.

Product Feature Questions

What's the difference between G7s Wanxiang and G7i?

① Functional positioning: G7s Wanxiang is the slush edition, supporting ice + ice water + slush triple functions; G7i focuses on ice making, producing solid high-clarity crescent ice.

② Slush configuration: G7s has a detachable electric slush cup with 0-contact ice drop for one-tap fluffy slush; G7i has no slush function.

③ Core purification: both use RO + mineral alkaline water with the same water-quality standard.

How do I use and clean the slush cup?

Put ice cubes made by the unit into the electric slush cup, mount the cup on the corresponding position of the machine, and start slush mode — it automatically blends fluffy slush. The cup is detachable for separate cleaning after use.

Before cleaning, ensure the unit is unplugged. The slush cup must not be rinsed as a whole unit — only the cup body can be rinsed.

After-Sales Questions

How long is the G7s warranty?

The G7s Wanxiang enjoys 3-year nationwide warranty. Quality issues within 3 years of purchase are repaired free of charge. It also includes 1-year replacement-only service — within 1 year, non-human quality problems are resolved by direct replacement, no repair needed. For support, contact the store where you purchased.

Does first use require on-site installation? Is there a fee?

The G7s is a no-installation countertop purifier — plug in, add water, and use; no professional installation needed. If you want first on-site commissioning service, book via the Bewinch WeChat mini-program. First on-site installation is free (including accessories and drilling, excluding natural marble countertops).

Is 7-day no-reason return supported?

Yes. Within 7 days of receiving the item, if water/power have not been connected, it has not been installed/used, accessories are complete, and it is resalable, you may apply for 7-day no-reason return. If water/power have been connected, no-reason return does not apply — contact the store where you purchased for warranty service.

Cooling & Modular Functions

What should I note for first cooling use?

On first use or after a power-cycle reboot to enable cold water, first place a container larger than 1.5L under the cold-water spout. Long-press "Cold/Stop" for ~5 seconds; after a beep, the light ring flashes. Wait 2–3 minutes for cold water to flow; the unit auto-stops, and cooling is activated. Flush 1–2 more times.

The unit does not enable cold water by default on power-up. Wait until the purified-tank level shows more than one bar, then long-press "Cold/Stop" for ~5 seconds to start.

How long does cooling take?

Cool-water C1 takes ~30 minutes; ice-water C2 takes ~60 minutes. High room temperature extends cooling time.

During cooling, the light ring breathes/flashes; when cooling ends it stays on. After 1 minute of no operation, the light ring turns off; tap a button to wake it.

How do I make sparkling water?

① Ensure the CO2 cylinder is installed and the handle is closed/locked; ② push the bottle forward to open the metal lever and turn clockwise to lock; ③ press the air-release button to make sparkling water.

Cylinders must be original from official channels. Before pumping, confirm the cylinder-base handle is closed/locked.

What is MixHub modular expansion?

The G7s Wanxiang has the MixHub dock, expandable on demand to ice, ice water, slush, and sparkling modules — one machine, multiple uses, expand as you drink.

When swapping modules, do so with power off and residual water drained; ensure the module is seated before powering on.

Brewing Function

How do I use Symboil variable-freq brewing?

The G7s features Symboil variable-freq technology with auto gentle/strong switching and six brewing levels. Place the cleaned brewing pitcher on the machine (ensure bottom is dry), select the tea icon, then press "Brew/Stop".

In high-altitude areas, perform a boiling-point detection first. The system auto-stops after brewing or keep-warm time; press "Reheat" to restart.

How do I clean and descale the brewing pitcher?

Daily cleaning: after the pitcher cools, remove the inner lid and tea basket; wash the body and parts with warm water. Never immerse the pitcher body in liquid.

Descaling: pour in white vinegar, let sit 1 hour, rinse 5–6 times; or add 6.5g citric acid with hot water, let sit 15 minutes, rinse 5–6 times. Repeat if needed.

Use & Maintenance

Why is hot-water flow slower than ambient water?

Based on the specific-heat formula Q=cmΔt: the higher the target temperature and the larger the temperature gap, the more energy required. At max power, the unit reduces flow rate to reach the target temperature — this is normal physical energy conservation. Higher temperature = lower flow.

Why can't it reach 100°C?

To avoid secondary contamination of purified water, the unit uses a sealed structure. Heating to 100°C causes boiling and steam, leading to excessive internal pressure in the heating tube. Thus heating temperature is controlled above 90°C and below 100°C.

The unit features RO and multi-stage deep filtration; output meets national direct-drinking standards and is safe to drink even unboiled.

What should I do before first use?

① Unbox and air in a cool ventilated place for 12–24 hours; ② fill the raw tank and power on to purify for ~10 minutes; ③ repeat ambient drain 3–5 times; ④ 45°C warm-water flush 1–2 times; ⑤ 98°C hot-water flush 1–2 times (beware splashing). More flushing = better taste.

How do I clean the purified / raw tank?

Clean the purified tank every 2–3 months: long-press "Dispense/Stop" for 5 seconds to drain, wipe inner walls with a non-woven cloth, refill and purify, repeat draining 2–3 times.

For raw-tank scale, dissolve 5–10g citric acid in 65°C hot water, fill the tank, soak 30–60 minutes, then wipe and rinse clean.

Do filters have a shelf life?

Filter shelf life is 5 years. Store unopened in a cool place — safe to stock up.

Display won't light?

Symptom: Display won't light, unit unresponsive.

Cause: Host power not connected.

Solution: Plug in the power cord and confirm the outlet has power. If still dark, contact the store where you purchased.

Unit not purifying or very low flow?

Symptom: No purification, or purified flow noticeably reduced.

Cause: Possible causes: filter beyond life or clogged; voltage mismatch; booster pump not working; raw water too cold.

Solution: ① Check filter life; replace if due. ② Confirm voltage matches the rating plate. ③ Listen for normal running/purification sounds. ④ Check raw-water temperature; replace with water at 5°C–35°C. If still not purifying, contact the store where you purchased.

No hot water?

Symptom: After selecting a hot temperature, no hot water comes out.

Cause: Possible causes: started dispensing before selecting a hot temperature; purified-tank level at minimum.

Solution: ① Follow the "dispensing hot water" section: select the temperature icon first, then press dispense. ② Wait for the purified tank to reach a higher level before dispensing hot water.

Off-taste / odor in output?

Symptom: Output has off-odor or abnormal taste.

Cause: Possible causes: filter beyond life; unit unused for a long time.

Solution: ① Check filter life; replace if due. ② If unused long-term, drain standing water and clean purified and raw tanks. For new units, complete the full flushing process.

Purified TDS stuck at 30?

Symptom: Purified TDS always shows 30, unchanged with use.

Cause: Raw water not changed.

Solution: Replace raw water then re-purify.

Brewing pitcher not heating?

Symptom: After selecting brewing mode, the pitcher does not heat.

Cause: Possible causes: set temperature below current pitcher temperature; dry-boiling triggered the thermostat protection.

Solution: ① Raise the set temperature (reheat level must exceed current tea temperature). ② Ensure there is water in the pitcher; after dry-boiling protection, refill before restarting.

Tea overflows during brewing?

Symptom: Tea overflows from the pitcher during brewing.

Cause: Possible causes: too much water above the MAX line; tea concentration too high causing foam.

Solution: ① Pour out some water to ensure level is below MAX. ② Reduce the amount of tea leaves. Total tea-water must not exceed 500 mL.

Water leaking from bottom?

Symptom: Pooled water under or around the unit.

Cause: Possible causes: spilled water during use; raw tank overfilled; raw-tank inlet/outlet valve loose; filter not seated.

Solution: ① Check for spills during use. ② Empty the tank, wipe the bottom, place on a flat surface and check for continued leaking; if leaking, check the raw-tank bottom inlet/outlet valve — rotate/press with a finger until leaking stops. ③ Power off, check filters are seated; remove all 3 filters in turn and reseat them. If still leaking after these steps, cut power immediately and contact the store where you purchased — do not disassemble yourself.

Prompts filter replacement but just replaced?

Symptom: After installing a new filter, the screen still prompts filter end-of-life.

Cause: Possible causes: filter not seated; Spin ID感应 contact poor; non-original filter.

Solution: ① Remove and reinstall the new filter, ensuring it twists to the locked position. ② After inserting, wait 60 seconds; if the sensor light doesn't change, pull out and re-insert. ③ Use Bewinch original filters; non-original ones may not be recognized. If still prompting, contact the store where you purchased.

Fault light on after long idle?

Symptom: After long non-use, the fault light comes on.

Cause: Normal prompt from changed standing water in lines after long idle.

Solution: No need to worry. Press "Dispense/Stop" to dispense, or do a drain operation to restore normal use. We recommend draining standing water and replacing raw water before reuse after long idle, repeating drain-purify 3 times.

Raw TDS shows 999 and alarm?

Symptom: Raw TDS shows 999, buzzer sounds, raw-water shortage light on, raw-tank ambient light flashing.

Cause: Local water is poor or raw water was not changed timely, pushing raw TDS to 999. Even after changing water, if purification hasn't run, it still shows 999.

Solution: ① Replace all raw water. ② After changing, dispense water so the unit starts purifying; the raw probe detects the new water quality and TDS drops. ③ If hard water cannot be changed, cancel the alarm sound by long-pressing the "75°C" temperature icon for 5 seconds; long-press again to restore.

White mist in tank on first purification?

Symptom: On a new unit's first purification, white misty cloudiness appears in the raw or purified tank.

Cause: After installing a new filter, first purification must fill the filter interior; the raw tank may expel air under pressure, producing dense "white mist" bubbles — a normal physical phenomenon.

Solution: This does not affect water quality; safe to drink. After multiple flushes, as air in internal filters/lines decreases, the effect weakens.

Noise / abnormal sound?

Symptom: Noticeable noise or abnormal sound during purification or heating.

Cause: Possible causes: raw-tank empty causing dry running; unit unsteady; filter not seated; normal pump sound (slight hum is normal).

Solution: ① Check raw-tank level; add water if empty. ② Adjust placement to ensure a level surface. ③ Open the top cover and check filters are seated. ④ Slight pump/heating sounds are normal. If there is明显 abnormal noise or vibration, contact the store where you purchased.

Spout dripping?

Symptom: After dispensing, the spout continues to drip.

Cause: Possible causes: foreign matter stuck in the outlet valve; residual water in lines; steam condensation after heating.

Solution: ① A few drips are normal residual line water. ② If continuous heavy dripping, check for blockage at the spout. ③ If unresolved, contact the store where you purchased.

E01 error code?

Symptom: Screen shows E01; unit stops dispensing and purifying.

Cause: Inlet water-temperature sensor abnormal; often in winter when ambient temperature is very low — the sensor detects ~0°C and triggers self-protection.

Solution: Move the unit to a warm room for 1–2 hours; it auto-recovers when the sensor warms. If it does not clear in a warm environment, the sensor or control chip may be faulty — contact official after-sales.

E02 when dispensing hot water?

Symptom: Screen jumps to E02 when dispensing hot water.

Cause: Inlet-temperature sensor open circuit (detected as 100°C), or the outlet NTC sensor has a crack letting in moisture.

Solution: Power off and restart to see if it recovers. If recurring, the outlet NTC may have a moisture crack — contact official after-sales for replacement/repair.

Outlet temperature sensor abnormal (E03/E04)?

Symptom: Screen shows E03 or E04.

Cause: E03 = outlet temp sensor short (detected as 0°C); E04 = outlet temp sensor open (detected as 120°C).

Solution: Auto-clears after the fault is fixed; if it persists, contact official after-sales to inspect the outlet temperature sensor.

Pitcher overheat shows E06?

Symptom: Screen shows E06 during brewing.

Cause: The pitcher has NTC self-protection; it triggers when internal temperature is too high — possibly dry boiling or thermostat protection.

Solution: Pour out hot water, refill with cold water, set the pitcher aside to cool, then return it to the unit — the error clears.

E11 heating error?

Symptom: Screen shows E11.

Cause: Heating fault: after 20 seconds of heating, temperature has not reached half the target.

Solution: Power off to clear; check if raw water is too cold. If recurring, contact official after-sales to inspect the heating system.

What to do for H01?

Symptom: Screen shows H01.

Cause: ≥3 days without hot-water dispensing; system prompts to drain.

Solution: Press the "Help" key on the display to enter "Smart Functions", select "Drain", long-press "Dispense/Stop" for 5 seconds to drain.

New unit shows 0403 and won't purify?

Symptom: New screen shows raw 04 / purified 03; unit won't purify.

Cause: Factory default. Before the factory water-run, a new unit defaults to raw 04 / purified 03 — this is not a fault; lines have simply not had water run through yet.

Solution: ① If the raw-replacement light shows 0403: check whether the raw-tank float was omitted; reseat the tank several times. ② If the raw-replacement light is off but 0403 persists: possibly the booster pump or waste solenoid valve is faulty — contact official after-sales.

Slow / low-volume dispensing?

Symptom: Output noticeably reduced or dispensing interrupted.

Cause: Filter beyond life or clogged; raw tank empty; very low purified flow.

Solution: ① Replace the filter. ② Add standard municipal tap water. ③ If slow persists after filter replacement, the diaphragm/booster pump may be faulty — contact official after-sales.

Tank has water but shows shortage / raw replacement?

Symptom: Raw tank has water but the unit still prompts raw replacement or shows shortage.

Cause: ① Tank float not seated or weak magnetism. ② Poor tank contact. ③ TDS 999 alarm.

Solution: ① Fill the tank to max, check the float is seated and floats in full water. ② Reseat the tank. ③ At TDS 999, after changing water, dispense so the unit purifies; the raw probe detects new water and TDS drops.

Steam / splatter when dispensing hot water?

Symptom: Steam or hot-water splatter when dispensing high-temperature water.

Cause: At high altitude, boiling point drops; large steam volume in the heating tube exits with the water.

Solution: In high-altitude areas, beware of hot-water splashing on first use; hold the container close to the spout, not far away. Some high-altitude areas may not support the max-temperature level normally.

Ambient no flow, 45°C gives scalding water?

Symptom: Ambient level gives no water, but 45°C gives scalding water.

Cause: Temperature sensor or heating control system abnormal.

Solution: This is a quality issue — contact the store where you purchased for a replacement or repair.

Raw tank leaking?

Symptom: Seepage at the bottom of the raw tank.

Cause: Raw-tank bottom valve loose or not seated.

Solution: Reinstall the bottom valve, ensuring it is tight. Contact the store where you purchased for an instructional video.

Leaking / noise after new filter install?

Symptom: Leaking and noise after replacing/installing a filter.

Cause: Filter not tightened or seated; using an old filter may cause poor sealing.

Solution: Retighten the filter, ensuring it is seated. We recommend using a new filter — old filters may restore bars but purification efficiency and speed will decline.

Continuous beeping during dispensing?

Symptom: No screen abnormality, but the unit beeps continuously during dispensing.

Cause: Heating element or diaphragm pump issue.

Solution: Contact official after-sales to inspect the heating element or diaphragm pump.

Touch unresponsive / buttons dead?

Symptom: Tapping the screen gives no response; all buttons dead.

Cause: Screen assembly fault.

Solution: If all buttons are dead, the screen assembly needs replacement — contact official after-sales.

Cold/ice module light ring not on?

Symptom: Cold-water or ice-module light ring not lighting.

Cause: If no operation for over 1 minute, the light ring auto-off enters eco mode.

Solution: Tap the "Cold/Stop" touch button on the panel to wake it.

Sparkling water no gas / insufficient bubbles?

Symptom: Poor gas flow or weak bubbles when making sparkling water.

Cause: ① CO2 cylinder exhausted. ② Cylinder-base handle not closed/locked. ③ Outlet valve blocked. ④ Water bottle not installed correctly.

Solution: ① Replace with an original CO2 cylinder (buy from official channels). ② Before pumping, confirm the cylinder-base handle is closed/locked. ③ Check the outlet valve for blockage. ④ Ensure the bottle pushes the metal lever forward and locks clockwise before pressing the air-release.

Tea outlet dripping during brewing?

Symptom: Tea outlet drips during brewing/steeping.

Cause: Foreign matter stuck in the upper-cup valve core.

Solution: Clean the upper-cup valve core and remove the foreign matter.

Tea flow slow / off-center?

Symptom: Slow or off-center tea flow.

Cause: ① Foreign matter stuck in the tea outlet. ② Foreign matter stuck in the upper-cup filter.

Solution: ① Remove and clean the tea-outlet conduit. ② Clean the upper-cup filter.

Lower cup tea not keeping warm?

Symptom: Tea in the lower cup cools quickly.

Cause: Drip tray loose or keep-warm switch off.

Solution: Reconnect the drip tray and turn on the keep-warm switch.

TDS stays 999 after changing water?

Symptom: New unit shows 999 for days despite changing water and draining repeatedly.

Cause: TDS probe scaled.

Solution: For a new unit, contact after-sales for an exchange, or contact the store where you purchased for inspection.

Raw TDS lower than purified TDS?

Symptom: Raw TDS reads lower than purified TDS.

Cause: ① You poured purified water into the raw tank — raw TDS is naturally low. ② New unit not fully flushed; internal lines not clean. ③ When raw water is too pure, the RO membrane produces little waste and flushes the purified probe less.

Solution: ① Use municipal tap water as raw water. ② Complete the full new-unit flushing process. ③ Use tap water with higher TDS for a week; raw TDS will rise above purified — this is normal and does not affect use.

Strong odor on new unit?

Symptom: Despite airing and repeated boiling, the new unit still smells strongly.

Cause: New-unit filters and lines may carry slight odor.

Solution: Open the top cover and purified-tank lid, air for 24 hours. If odor persists, brew citric acid and pour it in to resolve.

Air-trapping leak after moving tank during purification?

Symptom: After moving the raw or purified tank during purification, air trapping and leaking occur.

Cause: Moving a tank while the unit is purifying lets air into the water path.

Solution: Do not move raw or purified tanks while purifying. Wait until purification completes, or power off, or move tanks when prompted to change water.

Insects entering the unit?

Symptom: Insects found inside or at the bottom of the unit.

Cause: The base has drainage holes (for safety against internal leaks); in insect-heavy environments they may enter.

Solution: ① Place the unit in a clean, ventilated, dry area; clean regularly. ② Place 1–2 non-toxic insect-repellent sachets around each of the four feet, flat and stable. The internal water path is fully sealed and does not affect water quality.

Error Code Quick Reference

Helpful Tips & Self-Service Methods

Slow/no/intermittent purification — suspected "air trapping"

Symptom: Slow purification, no flow, or intermittent dispensing — suspected air trapping.

Solution: ① Power on and wait for purification to start (pulsing "thump-thump" sound); after purification completes, open the top cover and pull out a filter. ② Use a chopstick to gently poke the holes at the filter bottom to release pressure/air (note: if the chopstick meets resistance, air trapping is confirmed; water may spray from the filter bottom — never point the bottom toward your face). ③ Repeat for each filter, then screw filters back, wipe the table, and close the cover — normal use.

Off-odor / plastic taste after new unit or water change, despite repeated flushing

Symptom: Off-odor or plastic taste persists after a new unit or water change, despite repeated flushing.

Solution: ① Open the top cover and purified-tank lid, air for 24 hours. ② If odor remains, brew edible-grade citric acid, pour into the purified tank to soak, then drain and flush 2–3 times. ③ Ensure you complete the full new-unit flushing (cold drain 3–5 times + warm flush 1–2 times).

Spout drips a few drops after removing the cup

Symptom: Spout drips a few drops after the cup is removed.

Solution: On a new unit, dripping is usually residual carbon powder or debris in the water path; drain a few more times (3–5) to normalize. If dripping continues after a period of use, contact the store where you purchased.

White floating particles in dispensed water

Symptom: White floating particles in dispensed water.

Solution: On a new unit or after a filter change, residual food-grade lubricant in lines may flow out — normal. After a few more drains (5–10 cups), particles disappear naturally. Harmless; safe to drink.

Screen numbers jumping, touch unreliable, intermittent

Symptom: Screen numbers jumping, touch unreliable, intermittent.

Solution: ① First wipe water off the screen with a dry cloth — capacitive touch triggers误动作 when wet. ② Check for unstable voltage; try a dedicated outlet. ③ If the screen still frequently jumps/flashes, the touch-film assembly may be faulty — contact after-sales for replacement.

Press dispense but no flow, display normal

Symptom: Press dispense but no water; display looks normal.

Solution: ① Check the top cover is pressed down firmly (an unseated cover triggers safety lockout). ② Power off for 1 minute, then restart. ③ Confirm the raw tank has water and the float floats normally. ④ If none of these work, the diaphragm pump may be a hardware fault — contact after-sales.

Does the purified tank need regular cleaning?

Symptom: Does the purified tank need regular cleaning? How?

Solution: We recommend every 2–3 months: ① Remove the raw tank; open the top cover and purified-tank lid. ② Long-press "Dispense/Stop" 5 seconds to drain; auto-stops when empty. ③ Wipe the inner tank walls with a clean lint-free non-woven cloth. ④ Refill the raw tank and wait for auto-purification. ⑤ Long-press to drain 2–3 more times — normal use.

Intermittent hot flow with steam

Symptom: Intermittent hot flow with accompanying steam.

Solution: With swirl-flow instant-heat technology, water passes through the heating tube and instantly heats to near 100°C, generating large steam volume — the flow is finer than ambient and may fluctuate. Normal. In high-altitude areas, lower boiling point causes similar effects; try 85°C.

Insects found at bottom/around the unit

Symptom: Insects found at the bottom or around the unit.

Solution: The base has drainage holes for safety; in insect-heavy environments they may enter. ① Place the unit in a clean, ventilated, dry area; clean regularly. ② Place 1–2 non-toxic insect-repellent sachets around each of the four feet. Internal water path is fully sealed and does not affect water quality.

Plastic taste after flushing — deep deodorizing

Symptom: Plastic taste remains after new-unit flushing; how to deeply deodorize?

Solution: New-unit water-contact plastic parts are factory deodorized, but sealed packaging may leave a slight plastic taste — normal. Standard method: air the purified tank for 12–24 hours, then complete flushing. If odor remains, use the "dish-soap method": dilute food-grade dish soap, pour into the purified tank and circulate/flush, then rinse repeatedly with clean water 3–5 times. See official video tutorial for details.

White scale/crystals on raw-tank inner wall

Symptom: White scale/crystals on the raw-tank inner wall.

Solution: After long use, white powdery scale may appear — normal. Descaling: ① Take a cup of ~65°C hot water, add 5–10g food-grade citric acid (adjust for severity), stir to fully dissolve. ② Fill the raw tank with tap water, pour in the citric acid solution. ③ Soak 30–60 minutes. ④ Wipe the inner wall with a clean cotton cloth until scale detaches. ⑤ Pour out citric water, rinse thoroughly with tap water.

New filter outer packaging swollen/bulging

Symptom: Newly received filter outer packaging is swollen/bulging.

Solution: This is normal. Filters undergo air-tightness testing before leaving the factory and are heat-sealed under pressure to preserve condition and filtration performance — hence the packaging may bulge. As long as the seal is intact, it is safe to use. Bewinch uses double heat-sealed packaging to protect filters during shipping.

Loud purification noise on first use

Symptom: On first use, purification sound is very loud.

Solution: This is normal. New-unit filters, booster pump, and internal lines contain lots of air; the pump compresses air and produces louder noise. After repeated purification-and-drain cycles fully wet internal lines, noise gradually decreases. If still loud, check the unit sits on a flat surface; a soft flat pad underneath reduces resonance.

Black powder in raw/purified tank on first water run

Symptom: Black powder appears in the raw or purified tank on first water run.

Solution: This is normal. Activated-carbon filters are sintered from carbon powder plus food-grade binder; new filters release a small amount of carbon powder on first use — non-toxic and harmless. For black carbon powder in the raw tank, flush the new unit 3–5 times. In the purified tank, simply rinse with tap water, wipe with a clean cloth, then drain-flush a few times.

Cloudy water with green/brown suspended matter in raw tank

Symptom: Water in the raw tank looks cloudy with green or brown suspended matter.

Solution: This is usually algae spores or pipe sediment from aging tap-water networks, more noticeable in summer. The raw tank holds unfiltered tap water; cloudiness does not affect output — after RO membrane filtration (0.0001 micron), microbes, bacteria, and impurities are all removed, and output is safe for direct drinking. We recommend cleaning the raw tank regularly.

Water leaking from bottom/around the unit

Symptom: Water leaking from the bottom or around the unit.

Solution: ① Immediately close the inlet valve (if any), stop water supply, and cut power. ② Self-check: check for spills during dispensing, and whether the raw tank exceeds the MAX line. ③ Open the top cover, check the three filters are seated; remove and reseat each in turn. ④ Wipe water off the table and unit bottom, then power on and observe. If leaking recurs, contact the store where you purchased.

What is TDS?

Symptom: What is TDS? Why do TDS numbers differ each time?

Solution: TDS (total dissolved solids) is the total of dissolved substances in water; higher numbers mean more minerals and impurities. TDS is determined by the raw water you add, not a fixed value. Internal pipes and filters retain some old water; after mixing with new water, the reading may be slightly higher than tap water. After changing raw water, dispense a cup so the unit purifies — the TDS probe updates to the new water quality.

Raw-tank leftover water getting more concentrated — what's "waste water"?

Symptom: Raw-tank leftover water gets more concentrated — what is waste water about?

Solution: RO membrane precision reaches 0.1 nanometer; to avoid impurity buildup clogging membrane pores, some water is used to flush the membrane surface — this flush water returns to the raw tank as "waste". Waste water is only slightly higher in salt than tap water, not sewage. We recommend pouring out all leftover raw water and refilling fresh each time; do not reuse waste water.

Fixed-volume dispensing inaccurate — measuring cup reads less/more

Symptom: Fixed-volume dispensing is inaccurate; measuring cup reads slightly less or more.

Solution: Residual water in the unit's pipes means fixed-volume dispensing has some normal error. Hot-water volume error may be slightly larger because flow speed changes with temperature. We recommend using an accurately marked measuring cup/bottle — this is within normal error range.

Vertical line/mark on the unit shell

Symptom: A vertical line/mark on the unit shell.

Solution: This is a natural weld line formed when plastic fuses during injection molding — an industry-wide phenomenon that does not affect use or appearance. We continuously improve the process to minimize weld lines.

How is filter-life indicator calculated?

Symptom: How is the filter-life indicator calculated? Must I replace when due?

Solution: Filter life is computed from three dimensions: ① Power-on time (like a food shelf life — it decays over time even unused after wetting); ② Raw TDS change (poorer water = faster consumption); ③ Cumulative dispensed volume (more dispensing = faster consumption). The life reminder is a suggested cycle, not a hard deadline, but we do not recommend waiting until the filter is fully clogged — otherwise the booster pump may overload or pipes may rupture.
