What is Mineral Alkaline Water?

Bewinch uses innovative natural mineralization, adding natural mineral alkaline media to the third-stage filter. Tap water first passes through the front composite and RO filters to become pure water, then undergoes deep mineralization through the natural mineral alkaline composite filter — output is weakly alkaline negative-ion water at around pH7.6, rich in calcium, magnesium, sodium, potassium, zinc and other natural mineral ions. The water tastes clean, crisp, and sweet.

Brewing tea with it better extracts tea polyphenols, bringing out the full color, aroma, and flavor of tea. For daily direct drinking it is sweet, mellow, and smooth — suitable for long-term use.

Creative Uses for Your Purifier

Accessories & Expansion

The G7 Heidelberg is a countertop no-installation classic purifier. The host integrates purification and instant heating; there is no refrigeration or ice module. Standard accessories and common replacement parts:

Please use Bewinch original filters. Non-original accessories may carry hygiene/safety and sealing risks, causing abnormal water quality or machine malfunction; damage caused thereby is not covered by warranty.

Core Parameters

Filter Information

The G7 Heidelberg uses three independent filters. When one reaches end of life, replace only that one. The panel shows smart filter-replacement reminders and monitors remaining filter life.

Filter life is not fixed; it depends on local water quality, daily usage, working pressure, inlet temperature, and power-on hours. In high-TDS regions, filters may decay faster — this is normal. The screen shows smart replacement reminders. Unopened filter media has a 5-year shelf life; store in a cool, dry place.

Energy & Environment

The G7 Heidelberg heats on demand with no repeated keep-warm power waste. Concentrated raw-tank waste water can be reused for mopping, watering, and toilet flushing — no waste. If idle for over 72 hours, before reuse drain all water, replace raw water, and repeat purify-drain 3 times.

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, and top cover.

The G7 Heidelberg is a no-installation countertop unit — plug in and use, no plumbing. Place on a stable, dry surface away from direct sunlight and oil fumes, near a grounded 220V/50Hz outlet. If any accessory is missing or the unit is damaged, contact the store where you purchased promptly.

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, purified tank, and top cover. Air the unit in a cool, ventilated place for 12–24 hours.

The unit and filters may carry a slight factory odor; please complete flushing 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 icon appears on the display; wait ~10 minutes until the purified-water level light goes out and purification completes.

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

Place a heat-resistant container larger than 2–3L under the spout. Long-press "Dispense/Stop" for ~5 seconds until the screen goes dark and the green dispense light comes on; the unit drains automatically and 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 and reinstall the raw tank; wait for purification to complete. Place a heat-resistant container under the spout, select 45°C, press "Dispense"; the red light comes on. Wait for auto-stop.

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

Fill and reinstall the raw tank; wait for purification. Place a heat-resistant container under the spout, select 98°C, press "Dispense"; red light on. Wait for auto-stop. Beware of hot splashing.

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

This "cloudiness" is not impurities or harmful substances — it is dense tiny bubbles formed by air dissolved in the water. Because Bewinch uses RO reverse osmosis with 0.0001-micron filtration precision, water molecules cannot pass the RO membrane under natural 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 — safe to drink. After multiple flushes, as air in internal filters and lines decreases, the effect weakens noticeably.

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 / 55 / 65 / 75 / 85 / 98°C icons; the selected icon flashes.

3. Press "Dispense/Stop" to dispense hot water at that temperature.

4. Press "Dispense/Stop" again to stop.

The spout lights blue for ambient water and red for hot water.

Fixed-Volume Dispensing

7 temperature presets and 6 fixed volumes. Tap volume "+" / "-" to select the output volume; within 10 seconds press "Dispense/Stop" and the unit starts dispensing. It stops automatically at the set volume — no overflow.

To select temperature first then volume: tap the temperature icon, then the volume level, then press "Dispense/Stop" to dispense at the chosen temperature and volume.

Drain Operation

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

Smart Features: Infrared Cup Sensor

The G7 Heidelberg has an infrared sensing zone. When the screen is off, placing a cup under the spout quickly wakes the display — no manual touch needed, for easier cup access.

Smart Child Lock

The G7 Heidelberg adds a one-touch child lock. When enabled, it locks all dispensing functions, effectively preventing young children or pets from accidentally triggering scalding or soaking furniture. When child lock is on, each dispense requires tapping the child-lock key to unlock; it re-locks automatically after dispensing.

On a new unit or after a reboot, child lock is off by default.

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 water-quality indicator; it cannot absolutely represent water quality. Range fluctuation based on water quality and environment is normal.

SNT Noise Reduction

The G7 Heidelberg uses optimized SNT noise reduction; running noise is ~49dB(A) — quieter, without disturbing home life or the office.

Temperature Presets & Fixed Volume

Six fixed-volume presets: select by cup size; tap to dispense, tap to stop. Paired with the infrared cup sensor, the screen wakes when you place a cup while it is off — easier dispensing.

In high-altitude areas, we do not recommend dispensing 98°C to avoid steam/splashing. Beware of scalding when dispensing hot water; children must operate under adult guidance.

Filter Structure & Life

The G7 Heidelberg uses three independent filters; one set is pre-installed. 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, that filter is at end of life and needs replacement.

When a filter-life indicator drops from 3 bars to 0, the unit beeps 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: Reset Procedure

G7 Heidelberg filter reset tutorial:

1. Long-press the 【98°C】 key for 5 seconds to start the filter-selection program; by default all three filter-life indicators flash in 3-bar mode.

2. Long-press the 【45°C】 key again for 5 seconds; release after a beep — Stage 1 resets, and its indicator stops flashing with all 3 bars lit.

3. Long-press the 【55°C】 key again for 5 seconds; release after a beep — Stage 2 resets.

4. Long-press the 【65°C】 key again for 5 seconds; release after a beep — Stage 3 resets.

If there is no operation for 10 seconds during reset, the program auto-exits. After installing a new filter, follow the new-unit flushing guide: drain with cold water 3 times to fully wet the new filter.

Replacement Notes

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

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

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

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

We recommend cleaning the purified tank every 1–2 months. Use a soft cloth (boiled and cleaned) to wipe inner surfaces of the tank and lid. After cleaning, reinstall, plug in, wait for the tank to refill, then enter drain mode and drain — repeat 2–3 times.

The tank has a built-in Helix UV lamp; do not power off during daily use.

Drip Tray Cleaning

During use, remove the drip-tray assembly and promptly clear accumulated water.

Body Care

For daily cleaning, wipe with a soft dry cloth; avoid corrosive cleaners or hard pads. Place 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 — repeat 3 times.

Full-Unit Self-Clean (H05 Mode)

When the display shows "H05", self-clean mode is active. This mode prevents the core RO membrane from being clogged by large amounts of calcium/magnesium particles (which would slow or stop purification). Run it periodically based on local water quality to effectively reduce clogging. The full program takes about 1 hour.

If you accidentally enter self-clean mode, long-press the "500mL volume" key for 5 seconds until "End" appears, then release — normal operation returns in ~5 seconds.

Self-clean video: https://www.bilibili.com/video/BV1GV4y1u7Sj/

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 — steadier operation and longer filter life.

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: Cleaning Schedule

Purified tank: Every 1–2 months, wipe inner surfaces and lid with a boiled, clean soft cloth; reinstall and drain-repeat 2–3 times.

Drip tray: Remove, empty, and rinse promptly.

Body: Wipe daily with a soft dry cloth; avoid corrosive cleaners and hard pads.

H05 Full-Unit Self-Clean

When the screen shows "H05", self-clean mode is active — it prevents RO membrane clogging by calcium/magnesium particles and relieves slow purification. Run it periodically based on water quality; the full program takes about 1 hour.

If you accidentally enter, long-press the "500mL volume" key for 5 seconds until "End" appears, then release — normal operation returns in ~5 seconds.

The tank has a built-in Helix 2.0 UV lamp; do not power off during daily use.

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 alkaline media to the third-stage filter. Tap water first passes front and RO filters to pure water, then deep mineralization — output at ~pH7.6, rich in calcium, magnesium, sodium, potassium, zinc — clean, crisp, sweet; brewing tea better extracts polyphenols.

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 infrared cup sensor?

The G7 Heidelberg has an infrared sensing zone. When the screen is in off-screen standby, place a cup under the spout in the sensing area; the screen automatically wakes and lights — no manual touch needed for easier cup access.

How do I use the smart child lock?

The G7 Heidelberg has a one-touch child lock. When enabled, it locks all dispensing functions, effectively preventing young children and pets from accidental operation. When child lock is on, each dispense requires tapping the child-lock key to unlock; it re-locks automatically after dispensing.

On a new unit or after a reboot, child lock is off by default.

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.

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 tank has a built-in Helix UV lamp; do not power off during daily use.

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.

What does H05 on the screen mean?

"H05" means self-clean mode is active — started to prevent the core RO membrane from being clogged by calcium/magnesium particles. Run it periodically based on water quality to reduce clogging. The full program takes ~1 hour. If entered accidentally, long-press the "500mL volume" key for 5 seconds until "End" appears, then release — normal operation returns in ~5 seconds.

How often should filters be replaced?

The G7 Heidelberg uses three composite filters: Stage 1 PP composite and Stage 3 mineral composite 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.

Use Questions

Is noise during purification normal?

Yes. RO units use a booster pump to push water through the membrane; purification makes some sound — normal pump noise. The unit is silent when not purifying, so it won't disturb daily life. The ~15-second swirl-convection flush after purification also makes a slight venting sound — this is the automatic membrane flush that protects filter life.

Does the purified tank need regular cleaning?

We recommend every 2–3 months. The tank is food-grade PP, detachable for washing; rinse clean and air-dry before reinstalling. The built-in Helix UV lamp continuously antibacterial during daily use; do not power off long-term.

After-Sales Questions

How long is the G7 Heidelberg warranty?

The G7 Heidelberg 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 G7 Heidelberg is a no-installation countertop purifier — plug in, add water, and use; no professional installation needed. If you want first on-site commissioning, 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.

Self-Clean & Sterilization

How do I use the self-clean function?

Place a heat-resistant container in front of the spout. Long-press the "Sterilize/Clean" key for 5 seconds to start self-clean; the unit automatically dispenses ~100 mL of 98°C hot water to flush lines, then auto-stops. Tap the key again to cancel mid-cycle. If unused for over 3 days, we recommend a clean.

Why doesn't the UV lamp light up?

The UV lamp uses smart detection — it is not continuously lit. To verify: with the purified tank full, turn off power, wait 30 seconds, then power on — the UV lamp lighting means normal operation.

Use & Maintenance

Why is hot-water flow slower than ambient water?

Based on the specific-heat formula: the higher the temperature, the more energy required. At max power, the unit reduces flow to reach the target temperature — normal physical energy conservation.

Why can't it reach 100°C?

In a sealed structure, boiling water produces steam that causes excessive internal pressure, so heating is controlled above 90°C and below 100°C. Output meets direct-drinking standards and is safe to drink.

How do I flush a new unit?

Air out 12–24 hours; after purification, ambient drain 3–5 times; then 45°C flush 1–2 times; then 98°C flush 1–2 times.

What is the 5L tank and 33% filter-life improvement?

The G7 Heidelberg has a classic 5L raw tank that reduces refill frequency. Compared with standard models, filter life improves by ~33%, reducing consumable replacement frequency — better suited for families.

Why does the unit produce waste water?

Waste water is concentrated water that flushes impurities off the RO membrane; purified-to-waste ratio is ~3:1. It is not drinkable but can be reused for mopping and watering.

Do filters have a shelf life?

Filter shelf life is 5 years. Store unopened in a cool place.

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 5–35°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.

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.

Infrared cup sensor unresponsive?

Symptom: After placing a cup, the screen does not auto-light.

Cause: Possible causes: cup not in the sensing area; dirt blocking the sensor surface.

Solution: ① Confirm the cup is directly under the spout in the infrared sensing area. ② Wipe the body's infrared sensor surface with a soft dry cloth to remove dirt. If still unresponsive, contact the store where you purchased.

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. 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 in turn and reseat. If still leaking, cut power immediately and contact the store where you purchased — do not disassemble yourself.

Accidentally entered H05 self-clean?

Symptom: Screen shows H05; unit in self-clean mode; cannot dispense normally.

Cause: Accidental operation triggered self-clean.

Solution: Long-press the "500mL volume" key for 5 seconds until "End" appears, then release — normal operation returns in ~5 seconds.

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.

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.

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.

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; filter-chip contact poor; non-original filter.

Solution: ① Remove and reinstall the new filter, ensuring it is tight. ② Check that the filter bottom chip contacts are clean. ③ Use Bewinch original filters; non-original ones may not be recognized. If still prompting, contact the store where you purchased.

Raw TDS shows 999 and alarm?

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

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 purifies; the raw probe detects new water quality and TDS drops. ③ If hard water cannot be changed, long-press the corresponding temperature icon for 5 seconds to cancel the alarm.

Scale on raw-tank inner wall?

Symptom: After long use, white powdery crystals form on the raw-tank inner wall.

Cause: Due to regional water-hardness differences, scale forms on the raw-tank wall over long use.

Solution: ① Take a cup of ~65°C hot water, add 5–10g food-grade citric acid, stir to fully dissolve. ② Fill the raw tank with tap water, pour in the citric acid solution. ③ Soak 30–60 minutes; wipe the inner wall with a clean cotton cloth until scale detaches. ④ Pour out citric water and rinse thoroughly.

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.

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 — 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.

Display abnormal?

Symptom: Display abnormal, e.g., temperature icon flashing, screen black, etc.

Cause: Display control module abnormal.

Solution: Contact official after-sales to replace the display assembly.

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 — normal, 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.

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.

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.

Off-odor / plastic taste after new unit or water change

Symptom: Off-odor or plastic taste persists 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 + warm flush 1–2).

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, 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

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.

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 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 inner 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.

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 — 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.

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, stir to dissolve. ② Fill the raw tank, pour in the citric acid solution. ③ Soak 30–60 minutes. ④ Wipe with a clean cotton cloth until scale detaches. ⑤ Pour out and rinse thoroughly.

New filter outer packaging swollen

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 — hence the packaging may bulge. As long as the seal is intact, it is safe. 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 purify-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. For black powder in the raw tank, flush the new unit 3–5 times. In the purified tank, rinse with tap water, wipe with a clean cloth, then drain-flush a few times.

Cloudy water with green/brown suspended matter

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

Solution: 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. Clean 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, and whether the raw tank exceeds MAX. ③ Open the top cover, check the three filters are seated; remove and reseat each. 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 flushes 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. Pour out all leftover raw water and refill fresh each time; do not reuse waste water.

Fixed-volume dispensing inaccurate

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 — 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 — 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 do not wait until the filter is fully clogged — otherwise the booster pump may overload or pipes may rupture.
