1. Choose a stable, ventilated countertop away from direct sunlight, heat sources, and heavy oil fume;

2. Leave ventilation space around the machine;

3. Fill the 5L side raw water tank with municipal tap water to the max line, replace the tank;

4. Place the brewing pot on the left base, plug in and go.

N7 supports both plumbed and non-plumbed modes:

œ Inlet: standard angle valve or 1/2" tap;

œ Drain: floor drain / drain pipe / wall drain;

œ Power: grounded 10A three-prong socket within 1.5m;

œ Water source: municipal tap water within 2m (5-35°C);

œ Clearance: height ≥45cm, width ≥36cm, depth ≥38cm;

œ Hole: countertop requires >14mm diameter hole.

Unbox, remove raw and clean water tanks, open the clean tank lid, and air out in a cool ventilated place for 12-24 hours.

Fill the raw tank with standard municipal tap water. After power-on, it starts purifying. Wait ~10 minutes - when the clean water level shows two bars solid, purification is complete.

Place a heat-resistant container (>3.5L) under the right spout. On the home screen, tap "Smart Functions" in the bottom right, select "Drain", tap "Start Drainage". The green light comes on, it drains and stops automatically.

After purification completes, tap "Dispense" on home screen, tap 45°C, press "Dispense/Stop" to dispense warm water until it finishes.

Same as Step 4 but select 98°C hot water, press "Dispense/Stop" to flush with hot water.

Ensure the brewing pot is on the machine. Tap "Brew Tea" on screen, select "Black Tea" mode, tap "Start Brewing". The machine auto-fills then heats; when heating completes it enters keep-warm. Press "Brew Tea/Stop" to end keep-warm, remove the pot and discard the water.

At high altitude, water does not reach 100°C when boiling. We recommend running a manual boiling-point detection: place an empty brewing pot on the machine, wait until the clean tank is full, then long-press "Brew Tea/Stop" for 5 seconds to fill the pot. The pot starts heating to detect the boiling point. When done, the machine beeps three times and enters standby. If you move to a different altitude, re-run boiling-point detection.

This machine has two spouts: left spout is for filling the brewing pot, right spout is for normal purified water dispensing.

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

2. For hot water, press 45/55/65/75/85/98°C to select the temperature, then press "Dispense/Stop";

3. Press "Dispense/Stop" again to stop when you have enough.

Tap the "+" / "-" volume buttons to select dispense amount. Within 10 seconds of selecting the volume, press "Dispense/Stop" - the machine dispenses the set amount. You can also select temperature first then volume, for quantitative tempered hot water.

1. Tap the icon for flower tea, fermented tea, herbal tonic, or boil water;

2. After selection, the machine offers different brew times; adjust with custom brew if needed;

3. Press "Brew Tea/Stop" - if the pot is on the machine it starts filling, default to 500mL (pot max level) before heating;

4. When heating time completes it auto-enters keep-warm, showing remaining keep-warm time.

Enter the brew customization page, set brewing parameters, tap "Schedule" in the bottom left, select the scheduled time, then tap "Start Brewing". The machine auto-fills water and starts heating at the scheduled time. You can view remaining schedule time on the home screen.

The machine fills first then heats to prevent the clean water running out during scheduling.

12 built-in tea presets, supports 11 custom profiles (5 tea + 6 drinking) to meet personalized needs. Set desired volume, temperature, time on screen, then long-press the custom icon for 5 seconds until you hear a beep = saved. One-tap recall when brewing or drinking.

Tap "Smart Functions" bottom right on home screen, enter smart functions, tap "System Settings" bottom right, enable "Screen Lock" on the right. Once on, the whole machine locks after 1 minute idle. During lock, dispensing operations are disabled (the clean jug can still be removed). Slide the touch screen to unlock and resume.

N7 monitors raw water purity in real time. During purification the tank ambient light changes color with raw TDS: ≥150 red, <150 blue - see water quality at a glance.

Powered by ANC smart chip algorithm, provides TDS monitoring, real-time temperature, filter life display - full machine status. Intelligently plans filter life based on water volume, quality, and usage time, with real-time reminders for filter/water changes.

On first power-on, the UV lamp runs for 1 hour, then auto-cycles every 30 minutes for 30 minutes each. When the clean jug is removed, the lamp turns off automatically; during purification it activates automatically.

When idle for a while the display dims; touch any button to wake it. Long-press "55°C" for 5+ seconds until TDS shows "ECO" to enter eco mode - turns off raw tank ambient light and pot auto keep-warm. Long-press again to exit.

5L large side tank, horizontal side tank design for easy lifting, structure fits sideboards. Non-plumbed plug-and-use, no plumbing constraints - suitable for living rooms, tea rooms, sideboards.

Can switch to automatic water supply (no manual water changes) mode, suitable even in areas with poor water quality. N7 supports free first on-site installation (including parts and hole drilling). One machine, two usage modes - switch at will.

Using Stage 1 as example:

1. Remove the clean water tank, open the machine top cover;

2. Twist the filter to be replaced from "Lock" to "Unlock" per the markings, pull out the old filter. Within 30 seconds the screen shows an alert and beeps;

3. Insert the new filter, twist from "Unlock" to "Lock" per markings. Within 30 seconds the alert disappears and the filter indicator becomes full - replacement complete.

The 1.3L hidden removable antibacterial jug is Tritan baby-grade material, light-blocking design. After drainage, unplug power, lift out the clean tank, wipe the inner surface and lid with a soft cloth that has been boiled in hot water, snap the lid back and reinstall. Keep surroundings clean and regularly clean the storage tank.

After the pot cools, remove it, twist counterclockwise to take off the lid, remove the metal/glass tea basket, wash the interior and parts with warm water. For tea scale/limescale buildup from long use, soak in white vinegar for 1 hour, or 6.5g citric acid + boiling water for 15 minutes, then empty and rinse 5-6 times with clean water.

Never immerse the pot body in any liquid. When returning to the machine, keep the pot bottom dry with no residual water.

During use, remove the drip tray assembly in the direction shown, promptly clear accumulated water, keep the dispensing area dry.

N7 monitors raw water purity in real time and auto-adjusts waste ratio - the cleaner the raw water, the less waste, net-to-waste ratio as low as 4:1, achieving Grade-1 water efficiency.

When the raw tank water level drops below the minimum mark, or raw TDS is too high, the "Change Raw Water" indicator lights and ambient light flashes. Empty the remaining water in the raw tank and refill with standard municipal tap water before continuing.

Waste water is not drinkable, but can be used for cleaning, watering plants, etc.

The brewing pot accumulates tea/limescale over long use; descale regularly:

Citric acid method: Pour in appropriate boiling water, add ~6.5g citric acid (or baking soda), soak 15 minutes, empty and rinse 5-6 times, repeat if needed.

White vinegar method: Pour in appropriate white vinegar, let sit 1 hour, empty and rinse 5-6 times.

To clean: let the pot cool, grip the inner lid and lift up → twist lid counterclockwise to unlock → remove tea basket, wash pot interior, inner lid, lid and basket with warm water, reassemble in order.

White foam is normal - it is essentially tiny bubbles that disappear when left to stand. Safe to drink.

œ Pressure change: during purification, pressure pushes water through the membrane and some air dissolves. When dispensing, pressure drops and dissolved air comes out as tiny bubbles.

œ Temperature change: when a new filter first purifies water it must fill the filter interior; the raw tank may show "white mist" of dense tiny bubbles due to pressurized air release. This is normal physics.

The mineral water filtered by N7 Hermann contains electrolytes. Beneficial minerals such as strontium, zinc, calcium, magnesium, sodium, potassium, selenium, and metasilicic acid exist as ions in the water. The water is approximately pH7.6 weakly alkaline, tasting close to natural spring water. Low sodium, light minerals, suitable for daily direct drinking and wellness brewing.

TDS is only a common pre/post purification indicator and does not absolutely represent water quality. Minor fluctuations based on water quality and environment are normal. If purified TDS stays unchanged, first change raw water and re-purify to observe. If the range is still abnormal, contact the store where you purchased.

Tap "Smart Functions" bottom right on home screen → "System Settings" → enable "Screen Lock". Once on, the machine auto-locks after 1 minute idle. During lock, dispensing is disabled (clean jug can still be removed). Slide the touch screen to unlock.

Set desired temperature, volume, heating time on screen, then long-press the corresponding custom icon for 5 seconds until you hear a beep = saved. N7 supports 11 custom profiles (5 tea, 6 drinking). To recall, press the custom icon then press "Dispense/Stop" or "Brew Tea/Stop".

Repeat to overwrite. New machines and after power restart, custom data is unset by default.

Poor local water quality or not changing raw water in time can cause raw TDS to reach 999 with an alarm. Fix: œ Replace all raw water and dispense water to let the machine re-detect; œ If you don't need the alarm sound, turn off "999 Alert" in "Smart Functions" → "System Settings".

High raw TDS accelerates filter consumption. When prompted, change raw water promptly; do not accumulate water for reuse.

Enter the brew customization page, set brewing parameters, tap "Schedule" in the bottom left, select the scheduled time, then tap "Start Brewing". The machine auto-fills and starts heating at the scheduled time. View remaining schedule time on the home screen.

The main unit comes with one each of Stage 1/2/3 filters. For this model, Stage 1 and Stage 3 filters are recommended every 6-8 months, Stage 2 filter every 2-3 years.

Actual life depends on power-on time, local water TDS, daily dispense volume etc. The panel has smart replacement reminders; replace with Bewinch genuine filters as prompted.

After filters expire, filtration gradually weakens, adsorbed harmful impurities saturate on the membrane, purification capacity drops, potentially allowing bacteria and impurities into drinking water causing secondary contamination.

Completely clogged filters can also cause booster pump overload, pipe rupture and other safety hazards. Replace promptly per panel reminders.

N-Series whole machine enjoys 4 years warranty: the first 2 years are "replacement-only" coverage - if quality issues arise within warranty, replace with a new machine directly; years 3-4 are nationwide warranty repair period, repairs are free.

For any product questions, contact the store's online customer service, or contact the store where you purchased.

Bewinch supports free first on-site installation (including installation parts and hole drilling, except natural marble countertops). Book via the Bewinch official mini-program, or contact the store's online customer service to help book.

N9 series orders also include a free on-site new-machine flushing service.

Tap "Help" on the screen and select "H2" from the menu to enable hydrogen production.

Align the hydrogen module/hydrogen-rich cup male plug with the dispensing socket, press until you hear a "click" = installed.

The hydrogen function does not work when the clean tank is empty. The hydrogen module electrodes have a service life; when degradation is obvious, contact after-sales for replacement.

Hydrogen molecules are unstable. We recommend drinking promptly after dispensing for best hydrogen concentration.

N9Max Yaoguang uses high-pressure steady-state hydrogen locking technology; at room temperature, 1-hour retention is still 60%+, and it stably retains hydrogen even in hot water. Other models should be drunk fresh.

N9Max Yaoguang is equipped with 4th-gen platinum hydrogen electrolysis and high-pressure steady-state hydrogen locking technology. Hydrogen production rate is 700% higher than the basic model, stably retaining hydrogen even in hot water - solving the pain point that ordinary hydrogen machines can't hold hydrogen in hot water and hydrogen molecules easily escape.

Based on specific heat Q=cmΔt, the higher the desired temperature, the larger the temperature difference between raw and target water, the more energy needed. The machine has limited power. To achieve fast heating, it reduces water flow to reach the target temperature. Higher temperature = less flow, consistent with physical energy conservation. Normal.

To avoid secondary contamination, the machine uses a sealed structure. Water heated to 100°C boils and produces steam, causing excessive pressure inside the heating tube. Although the tube has an automatic high-pressure relief valve, after steam releases, re-filling and reheating causes slow heating and energy waste. Therefore dispenser heating temperature is usually controlled above 90°C, below 100°C.

The machine uses high-precision reverse osmosis RO membrane and multi-stage deep filtration; dispensed water meets national direct drinking standards and can be drunk directly even without boiling.

The machine detects the instantaneous temperature after the heating system. As purified water flows from spout to cup, water temperature changes with ambient temperature. The temperature control component auto-adjusts based on ambient temperature.

Manual correction: œ Continuously dispense 98°C water for 1-2 minutes; œ Then dispense 85°C water for 1-2 minutes; œ Then continuously dispense hot water until switching to 45°C water and continue 1-2 minutes. This helps the machine adapt to current ambient temperature.

When temperature is not adjusted, the screen shows real-time ambient temperature, which changes with room temperature. The temperature probe is sensitive; when room temperature is at a threshold (e.g. 27-28°C), the display may jump back and forth between two degrees. Normal, does not affect daily use.

Due to the machine's water path design, quantitative dispensing may have ±10mL error because a small amount of water remains in the tubing. Normal. Hot quantitative error may be slightly larger because water flows slower and thinner at different heating temperatures. We recommend using a measuring cup with precise markings.

œ Open the machine top cover; œ Grip the handle above the filter, rotate the pointer from "Lock" to "Unlock", gently lift out the old filter; œ Align the new filter pointer with the "Unlock" mark and insert into the corresponding slot, grip the handle and rotate to "Lock".

After replacement, long-press "Dispense/Stop" for 5 seconds to drain; drain 2-3 times then normal use. N-Series uses Spin ID/chip auto-sensing reset; after inserting the new filter the indicator auto-restores to full.

Three dimensions: œ Power-on time (like food shelf life - once water passes through, it counts even if unused); œ Raw water TDS change (dirtier water = shorter filter life); œ Dispense volume (more water = shorter life).

The filter life indicator is a recommended replacement cycle, not mandatory. But don't wait until the filter is completely clogged, as that can cause booster pump overload, pipe rupture and other safety hazards.

Filters have a five-year shelf life. Keep the sealed bag unopened and store in a cool place. No need to worry about stockpiling expiring.

Non-genuine filters may have unguaranteed raw material hygiene, reduced filtration performance and seal matching, causing abnormal water quality and affecting machine life. Filters purchased through non-official channels cannot be reset and the machine will not work. Please purchase genuine filters from authorized channels.

When the screen shows the red water cup icon prompting raw water change, empty the remaining water in the raw tank and refill with municipal tap water.

You don't need to power off every time; just ensure the booster pump is not running when removing the tank. Do not remove the tank during purification, as this can cause the machine to suck in air and malfunction.

"Waste water" is actually concentrated water produced during filtration - in RO reverse osmosis machines, it rinses impurities off the RO membrane to maintain filter life. Bewinch net-to-waste ratio is about 3:1. Waste water is cleaner than tap water (but not drinkable) and can be collected for mopping, watering plants, etc.

Raw water and waste water share one tank; the raw water inlet is on the upper layer and the waste water outlet is on the lower layer. Because waste water is denser, it naturally stratifies with raw water. Combined with the machine's internal membrane flushing technology, there is no repeated filtration of waste water. The machine has a built-in clean tank where multi-stage filtered pure water is pre-stored, ensuring drinking safety.

Possible causes: œ You poured purified water into the raw tank, so raw TDS is naturally low; œ New machine not fully flushed; œ When raw water is very pure, the RO membrane produces little waste water, which means less flushing of the purified probe, so the purified reading may be slightly higher. Using municipal tap water as raw water and completing the full new-machine flush will make raw value higher than purified value. Normal.

After a new filter is installed, the RO rejection rate gradually climbs. We recommend dispensing more water daily to help the rejection rate climb; when it reaches 97%, the TDS will drop. Bewinch purified direct-drinking standard range is 0-30.

Take a cup of 65°C+ hot water, pour in 5-10g citric acid (adjust amount based on scale severity), wait for full dissolution and let the water cool; fill the raw tank with tap water and pour in the dissolved citric acid water; wait 30-60 minutes then wipe the inner wall with a clean cotton cloth until scale comes off; dump the citric acid water and rinse thoroughly with tap water.

We recommend cleaning every 2-3 months. Remove the raw tank, open the machine top cover and clean tank lid; long-press "Dispense/Stop" for 5 seconds to drain, auto-stops when done; repeatedly wipe the inner wall with a clean lint-free non-woven cloth; reinstall raw tank filled with water, wait for auto purification; drain again 2-3 times.

Algae spores floating in the air enter the water and grow into algae where there's plenty of light. Place the machine away from direct light, clean the tank promptly; soak and wash the inner wall with citric acid solution.

It's not a de-air sound - it's the normal filter flushing sound. After purification, the machine runs a ~15-second vortex convection flushing program that rinses ionic impurities off the membrane surface, protecting filter life and drinking health. It auto-runs after every purification cycle.

œ Scan the Bewinch mini-program code on the machine, select "Install/Repair", fill in info and submit; œ Contact the store where you purchased. When reporting a repair, provide the machine SN code (QR code).

Immediately close the inlet valve (plumbed model), stop water supply, then cut power. Promptly contact official after-sales; do not disassemble yourself.

œ Remove the raw tank, take out the silicone pad to reveal the arrow indicator; œ Use a tool to rotate the arrow clockwise 90° to the lock mark (non-plumbed is unlock mark), reinstall the silicone pad and raw tank; œ Open the tee valve inlet hose switch; œ Plug in power; œ Press "Smart Select" bottom right on screen, tap "System Settings", enable tap water continuous supply mode; œ The main screen shows the "tap" icon = switch complete.

On the customization page, enter the edit interface via the top right, tap "Rename", select the profile to rename, enter the input method page (supports Chinese/English toggle), edit and tap "Done" to save.

Symptom: Display dark, machine not purifying or working.

Cause: Power not connected, or supply voltage doesn't match rated voltage on nameplate.

Solution: œ Check the plug is firmly inserted and the socket has power; œ Confirm supply voltage matches nameplate rating. If still dark, contact the store where you purchased. Do not disassemble.

Symptom: No purification, or very low purified water flow.

Cause: Possible: filters expired or clogged, booster pump not working, raw water too cold, raw tank empty.

Solution: œ Check filter life indicator, replace if expired; œ Listen for normal running/purifying sounds; œ Replace with municipal tap water at 5-35°C; œ Check raw tank level and add water. If still not purifying, contact the store where you purchased.

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

Cause: Didn't select hot temperature first before dispensing, or clean tank is at minimum level.

Solution: œ First press the desired temperature icon, then press "Dispense/Stop" for hot water; œ Wait until clean tank reaches high level before dispensing hot water. If still no hot water, contact the store where you purchased.

Symptom: After selecting brew, the pot doesn't heat.

Cause: Set heating temperature is lower than current tea/water temperature in the pot, or the pot triggered dry-boil thermostat protection.

Solution: œ Raise set temperature above current tea temperature; œ Confirm the pot has water - dry-boil protection resets after adding water. If still not heating, contact the store where you purchased.

Symptom: Tea/water overflows from the pot during brewing.

Cause: Too much water added over MAX line, or tea concentration too high producing lots of foam.

Solution: œ Pour out some water, ensure level is below MAX (tea ≤500mL, boiling water ≤700mL); œ Reduce tea leaf amount; we don't recommend brewing overly concentrated tea.

Symptom: Plastic taste, disinfectant taste, or other off odor in dispensed water.

Cause: New machine not fully flushed, filters expired, or long non-use causing stagnant water.

Solution: œ Complete the full new-machine flush; œ Check filter life, replace if expired; œ Drain stagnant water and clean clean tank, brewing pot and raw tank. If odor persists, contact the store where you purchased.

Symptom: After installing a new filter, the screen filter indicator doesn't return to full.

Cause: Filter not twisted fully in, anti-counterfeit electronic tag not recognized by sensor module, or non-genuine filter used.

Solution: œ Remove the new filter and re-twist to "Lock" position, confirm no looseness; œ Within ~1 minute after power-on, the corresponding filter indicator should restore to full; œ Please use Bewinch genuine filters. Note each chip can only reset once; if still abnormal, contact the store where you purchased.

Symptom: After pulling out the clean tank, the clean water level light flashes and beeps 3 times.

Cause: This is a normal prompt reminding you the clean tank is not on the machine.

Solution: Reinsert the clean tank correctly and press down firmly to seat it. The beeping and flashing stop.

Symptom: After long non-use, the screen shows periodic drain prompt or abnormal indicator.

Cause: Normal prompt that residual water in the tubing changed after long standing.

Solution: No need to worry. Press "Dispense/Stop" to dispense water, or run one drain cycle to recover. We recommend running a full drain-flush before reusing after long non-use.

Symptom: The outer plastic wrap on a new filter looks puffed up.

Cause: After production, filters are gas-filled for air-tightness testing and better filtration speed, then plastic-sealed for storage.

Solution: Normal, no need to worry. Bewinch uses double-layer plastic sealing; as long as the seal is intact, it's safe to use.

Symptom: White powdery crystals form on the raw tank wall after long use.

Cause: Water hardness varies by region; long use forms limescale on the wall.

Solution: œ Take a cup of ~65°C hot water, add 5-10g food-grade citric acid and stir to dissolve; œ Fill raw tank with tap water and pour in the solution; œ Soak 30-60 minutes, wipe with clean cotton cloth until scale comes off; œ Dump citric acid water, rinse thoroughly with tap water.

Symptom: After enabling hydrogen mode, no bubbles or noticeably lower hydrogen concentration.

Cause: Possible: environment too dark (photosensor auto-disables hydrogen), hydrogen module expired, module not installed correctly, clean tank empty.

Solution: œ Check ambient light, brighten and observe; œ Check hydrogen module life (~2-3 years), replace if expired; œ Reinstall hydrogen module, ensure plug seats; œ Confirm clean tank has water. If still ineffective, contact the store where you purchased.

Symptom: White fog-like deposits on the inside of the hydrogen power window.

Cause: Stage 3 filter uses imported sintered coconut shell activated carbon. The carbon contains fine taste factors (trace minerals) that improve taste. Because N-Series hydrogen content is high and hydrogen is reducing, these fine taste factors are reduced by hydrogen, producing white fog on the cup wall.

Solution: This does not affect water quality; water is safe to drink. The hydrogen window is removable; clean periodically (every 1-2 months recommended).

Symptom: Hydrogen cup / hydrogen window needs periodic cleaning.

Cause: Long use may accumulate mineral deposits on the cup interior.

Solution: œ Place a 3.5L container under the spout; œ Tap "Help" → "Clean H2 Tank", confirm and wait for drainage; œ When drainage completes and you hear a "click", pull out the hydrogen cup (if it won't come out, press inward once until you hear "click", then pull); œ Wash the hydrogen cup and reinstall. Clean every 1-2 months.

Symptom: Screen shows E02 when dispensing hot water.

Cause: Inlet temperature sensor open circuit (reads 100°C), or outlet NTC sensor cracked and taking in moisture.

Solution: Power off and restart to see if it recovers; if it recurs, the outlet NTC sensor may have cracked and taken in moisture - contact after-sales for replacement or repair.

Symptom: Screen shows E03.

Cause: Outlet temperature sensor short circuit (reads 0°C).

Solution: Clears automatically after the fault is fixed; if persistent, contact after-sales to inspect the outlet temperature sensor.

Symptom: Screen shows E04.

Cause: Outlet temperature sensor open circuit (reads 120°C).

Solution: Clears automatically after the fault is fixed; if persistent, contact after-sales.

Symptom: Screen shows E07.

Cause: Drainage abnormal - continuous draining for 10 minutes still not complete.

Solution: Power off to clear; check if the drain line is blocked. If recurring, contact after-sales.

Symptom: Screen shows E11.

Cause: Heating fault - after 20 seconds of heating it hasn't reached half the target temperature.

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

Symptom: Screen shows H01.

Cause: No hot water dispensed for ≥3 days; machine reminds you to drain for maintenance.

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

Symptom: Screen shows H02.

Cause: Product unused for over 72 hours (3 days).

Solution: Long-press "Dispense/Stop" for ~5 seconds to drain; H02 auto-clears when reaching low level. Before reusing, dump remaining raw water, refill, and repeat draining 3 times.

Symptom: New machine screen shows raw 04 purified 03, not purifying.

Cause: Factory default setting. Before water passes through, all machines default to raw 04 purified 03. This is not a fault - the water path hasn't actually run water yet.

Solution: œ If raw-change light is on showing 0403: check if the raw tank float is missing, reinsert the tank several times; œ After completing the new-machine flush, the machine purifies normally and the display updates; œ If raw-change light is off but still 0403: possible booster pump or waste-water solenoid valve fault - contact after-sales repair.

Symptom: Noticeably reduced output or dispense interruption.

Cause: Filters expired or clogged; raw tank empty; low purified flow.

Solution: œ Replace filters; œ Add standard municipal tap water; œ If slow persists after filter replacement, possible diaphragm/booster pump fault - contact official after-sales.

Symptom: Hot water stream is thin, intermittent, with steam coming out.

Cause: Models using swirling instant-heat true-boiling technology heat water instantly to 100°C in the heating tube, producing lots of steam. To maintain accurate temperature, the hot stream is thinner than ambient water. Normal.

Solution: Normal physics, no action needed. May be more pronounced at high altitude due to boiling point.

Symptom: 98°C output is noticeably smaller than ambient water.

Cause: Per Q=cmΔt, higher temperature needs more energy; once power maxes out, flow is reduced to reach target temperature. Normal energy conservation.

Solution: Normal. If you need larger hot flow, consider flagship models with RH servo instant-heat technology.

Symptom: Raw tank has water but machine still prompts raw change or shows low water.

Cause: œ Tank float not installed correctly or weak magnet; œ Poor tank contact; œ TDS 999 alarm.

Solution: œ Fill tank to max mark, check float is installed and floats in full water; œ Reinsert the tank; œ At TDS 999, after changing water you must dispense water so the machine purifies; once the raw probe detects new water quality, TDS drops.

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

Cause: At high altitude the boiling point is lower, producing more steam in the heating tube; steam comes out with the water.

Solution: At high altitude, be careful of hot splashing on first use; some areas may not be able to use the highest temp. Hold the container close to the spout, don't reach far away.

Symptom: Seepage from the bottom of the raw tank.

Cause: Bottom valve loose or not installed correctly.

Solution: Reinstall the bottom valve, ensure it's tightened. Contact the store where you purchased for a video guide.

Symptom: New machine spout keeps dripping.

Cause: New machine tubing may have debris preventing the valve from sealing fully.

Solution: Drain several times to flush out debris. If dripping persists after multiple drains, contact after-sales.

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

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

Solution: Re-tighten the filter, ensure it's seated. We recommend using new filters; old filters restore the indicator but purification efficiency and speed decline.
