Product Overview

Suitable Households & Scenarios

The S9 Mingzhi is the flagship tea-brewing model of Bewinch's Schopenhauer premium tea-master series, designed for users who understand and love tea and who value wellness and ritual in daily life. With its dual water path (purified water + brewing) and the ITB-S4.0 smart tea system, it suits the following people and scenarios:

Who is it for?

Serious tea lovers: Dark tea, white tea, black tea, and scented tea can be slow-brewed at different temperatures, each tea at its ideal heat; six brewing temperatures from 65-98°C restore each tea's original character.

Wellness users: Ginseng, cordyceps, lingzhi, dendrobium, and other precious ingredients can be slow-brewed for 10-30 minutes at a true 100°C boil to fully release their nutrients.

Quality families: A 5L raw-water tank + 2L purified tank meets the daily drinking and tea needs of a family of 5-7; non-plumbed, plug-and-play.

High-end business spaces: Living rooms, tea rooms, studies, reception rooms, and premium clubs, combining practical use with display quality.

Why choose the S9 Mingzhi?

① A purifier that brews tea: Most purifiers only "boil water" — the S9 "brews tea," using simulated open-flame even-heating to break through the 100°C limit.

② Good water makes good tea: Its strontium alkaline water (pH7.6) raises tea-polyphenol extraction by about 30%; alkaline slow-brewing raises ginsenoside and cordyceps-polysaccharide release by about 44%.

③ Hassle-free, non-plumbed: Built-in tank, ready when powered on, no under-sink plumbing; place it anywhere in a living room or tea room.

④ Long warranty: The S-series enjoys a 4-year nationwide warranty (incl. 2-year replacement-only), worry-free ownership.

Product Positioning

The S9 Mingzhi is the smart all-in-one tea purifier of Bewinch's Schopenhauer premium tea-master series (S-series); its marketing name is S9 Mingzhi and factory model is RT701M. "Hidden in the city, tranquil in resolve" — through intelligent engineering it simplifies the elaborate ritual of hand-brewing tea, embodying the golden mean within tea: steeping, brewing, and extraction, finely crafted to achieve the most sincere and mellow tea flavor.

The S9 Mingzhi has a dual water path (purified water + brewing) and carries the ITB-S4.0 smart tea system, adapting to each tea and brewing it the right way — whether highly fermented dark tea or precious herbal drinks like ginseng, cordyceps, and lingzhi. It integrates tea extraction, wellness slow-brewing, and healthy drinking.

What is Simulated Open-Flame Even-Heat Brewing?

Traditional tea brewing is complex and elaborate, but rushing it easily loses the tea's true flavor. The S9 Mingzhi uses simulated open-flame energy-concentrating even-heating technology to mimic live-flame active heating, breaking through the 100°C limit. The thick-film heater heats the whole surface evenly, with high thermal efficiency; the tea and water are heated more uniformly so nutrients are fully released.

Its core features can be summed up in four points: simulated open-flame even heat, gentle-and-strong fire brewing, near-temperature algorithm, and a true 100°C boil. Tap to start tea-brewing or wellness slow-brewing, wait a moment, and a professional-grade tea is served.

Who is it for?

Tea lovers: Dark, white, black, and scented tea slow-brewed at their own ideal temperatures for a mellow tea soup.

Wellness users: Lingzhi, cordyceps, dendrobium, and other precious ingredients slow-brewed for 10-30 minutes.

Home daily use: Dual water path runs purification and brewing at the same time; brewing and water dispensing never interfere.

Core Technology Details

ITB-S4.0 Smart Tea System

The S9 Mingzhi fully upgrades the ITB-S4.0 smart tea system, expanding tea-brewing and wellness. Adapting to each tea and brewing it the right way, it integrates tea extraction, wellness slow-brewing, and healthy drinking, giving tea and wellness lovers a professional-grade tea experience.

Simulated Open-Flame Even-Heat Brewing

The S9 Mingzhi uses simulated open-flame energy-concentrating even-heating to mimic live-flame active heating, breaking through the 100°C limit. The thick-film heater (thick-film rare-earth heating module) heats the whole surface evenly with high thermal efficiency, so the tea and water heat uniformly and nutrients are fully released. Features: simulated open-flame even heat, gentle-and-strong fire brewing, near-temperature algorithm, true 100°C boil.

Flow-Through Tea-Water Separation Chamber

Bewinch's innovative flow-through automatic tea chamber fills by itself, spraying hot water from the top to steep the ingredients from above, kneading fresh nutrients into every drop. It can brew or steep, each tea at its own temperature. Structurally: top hot-water spray, automatic tea-water separation, 60°C coaster warming, and tea drops into the cup when ready.

Dual Tea Filtration, No Tea Leaves in Cup

To prevent tea leaves from spoiling the drinking experience, the S9 Mingzhi has a two-stage tea filter: a first removable metal tea basket that thoroughly strains leaves, and a second fine fixed filter that catches the small particles the first misses. The tea chamber is also removable so users can clean and maintain it themselves, ensuring every sip is clean and pure.

Strontium Alkaline Mellow Water

Using selected natural mineralizing media, raw water is first filtered into pure water, then mineralized into strontium alkaline mineral water containing strontium, calcium, magnesium, potassium, sodium, zinc, and metasilicic acid. With deep mineralization technology it produces alkaline mineral water around pH7.6 that tastes like spring water, sweet and refreshing.

The mineral ions in strontium alkaline water raise tea-polyphenol extraction by about 30%; alkaline slow-brewing also raises the release of ginsenosides and cordyceps polysaccharides by about 44%.

The S9's mineralizing alkaline filter has a theoretical service life of 6-8 months; the mineral content decreases as the filter is used, weakening mineralization. Replace promptly when the machine's life monitor reminds you.

APQ2.0 Nano-Bionic Barrier

The S9 Mingzhi uses an upgraded APQ biomimetic membrane, inspired by nature and borrowing the selective permeability of living cells to water, achieving efficient molecular screening and separation that blocks bacteria, heavy metals, and pesticide residues. Compared to traditional Bewinch RO reverse osmosis, it offers higher filtration efficiency and purification, with performance that does not easily decay over long use; the resulting small-clustered water is more readily absorbed by human cells.

Upgraded RH2.0 Honeycomb Heating

R-heating instant technology uses an AI smart honeycomb heating structure, combining smart preheating, dual-path instant heating, and smart temperature sensing. Compared to traditional thick-film rare-earth instant heating, hot-water flux above 85°C rises by over 100%; with dynamic temperature sensing and smart control, it heats cold water to 98°C in 3 seconds, so no waiting even for a crowd.

Heating is affected by altitude; above 1,800m it may not reach the set temperature. Please consider this before ordering.

Helix2.0 Long-Lasting Sterilization

A built-in Helix2.0 UV lamp self-starts on a 24-hour cycle, reaching a 99.99% sterilization rate. Safe, reliable, and chemical-free, it prevents bacteria and viruses from growing in the purified tank when water sits unused, so you can drink safe water even after being away.

The 99.99% rate comes from a professional lab environment; real-world results vary with temperature, season, and placement. Clean the purified tank regularly.

Placement (Non-Plumbed)

The S9 Mingzhi is a non-plumbed countertop unit with its own raw tank — just add tap water, no water line needed:

Placement① choose a well-ventilated, level, stable surface away from direct sun and heat; ② leave ventilation gaps around the unit — don't push the back/sides against a wall or stack items; ③ the surface must support ~13kg (full); ④ nearby 220V 3-prong grounded outlet, cord reaching naturally without strain.
Pre-Power Check① confirm all three filters are seated by their marks; ② fill the raw tank with municipal tap water (5°C-35°C) and seat it level; ③ confirm voltage matches the label (220V~ 50Hz) before plugging in; ④ for first use, always complete the "New-Unit Flushing Guide" below — do not drink directly.

The S9 Mingzhi needs no under-sink piping, tee valves, or drain connection. To move it, power off and empty the tanks first.

New-Unit Flushing Guide

Before first use, flush as follows to activate filters and clean pipes. The process takes about 30-40 minutes.

Step 1: Air Out

Unbox, open the purified-tank lid, and air out in a cool ventilated place for 12-24 hours.

Step 2: Power On & Purify

Fill the raw tank, power on to start purification, wait ~10 minutes until the water level shows 2 bars.

Step 3: Drain Cold Water (repeat 3-5 times)

Place a heat-resistant container (2-3L) under the spout. Tap the top-left menu key, choose "General Settings", choose "Drain", press "Start" when prompted; the green light drains and stops automatically when done.

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

After purification, press "Custom Water", choose 45°C and "Continuous Flow", press "Start", wait for auto-stop.

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

After purification, press "Boiling Water", press "Start", wait for auto-stop.

Step 6: Clean the Tea Path (repeat 1-2 times)

After purification, select "Tea Brew", tap start, wait for the brew to finish, then tap "Pour Tea" — one tea-path clean is complete.

New units and filters carry a slight factory smell; always complete the flushing. The more flushing, the better the taste. Adjust airing time to the actual smell. Video: https://www.bilibili.com/video/BV1wb4y1w7Eu/

First Time Brewing Tea

1. Before the first brew, complete the "tea-path clean" step above so the brewing water path and chamber are fully soaked and clean.
2. Put the right amount of tea into the removable metal basket, place it in the chamber, and make sure the basket clicks in.
3. Brewing defaults to 500mL fill; ensure the upper-cup chamber water does not exceed the max line (max 800mL).
4. We recommend first running one empty water brew through the path before adding tea.

During brewing, filling must be stopped manually (never over the max line). Do not touch the hot base during use to avoid burns.

Filters & Care

Filter Structure & Life

The S9 uses three independent filters — replace whichever reaches end of life, not the whole set. Pur-Smart plans filter life by water usage, quality, and time, showing remaining life on screen.

StageReplacementFunction
Stage 1 (M2pro pre-filter MC121)~6-8 monthsPre-filtration: sand, rust, large particles; adsorbs chlorine & odor
Stage 2 (APQ2.0 R123/100G)~2-3 yearsCore purification: heavy metals, pesticides, bacteria; faster flow, safe water
Stage 3 (Q2-Sr+ strontium alkaline QC115)~6-8 monthsPost mineralization: adds strontium, pH7.6 mellow water

When the main-screen filter life drops from 100% to 0%, the unit beeps for 10 seconds at each dispense — it is time to replace.

Filter Replacement & Reset

Spin ID Smart Sensor Reset (Stage-1 example)

When filter life ends, the screen shows 0% and beeps 10 seconds at dispense.

1. Turn the old filter from "lock" to "unlock" by the mark and pull it out; the screen shows an alert "Filter 1 detection abnormal".

2. Insert the new filter, turn from "unlock" to "lock" by the mark; a beep sounds, the screen returns to the main page, and filter life restores to 100% — done.

① If the indicator doesn't change within 30s, pull out and re-insert; repeat until auto-reset. ② Each filter chip resets only once — wait for the monitor reminder. ③ After replacing, drain cold water three times to soak the new filter. Video: https://www.bilibili.com/video/BV1DC4y167sV/

Filter Life Notes

Actual life depends on power-on time after activation, local raw-water TDS, and daily dispensing. In poor-quality water or high-use situations, replacement shortens.

Non-original filters may lack hygiene assurance, filtration, and sealing, causing water-quality issues and safety risks and shortening machine life. Buy replacements only from our authorized e-commerce platforms, dealers, or official channels.

Brewing Module & Daily Cleaning

Tea chamber & filters: The chamber is removable with a double filter (removable metal basket + fine fixed filter). After each brew, remove the basket, empty leaves, rinse filters and chamber with clean water, and wipe with a soft cloth to keep the path odor-free.

Raw tank: The 5L float-sensing raw tank is quick-release; clean every 1-2 weeks. Remove, rinse the inside, wipe with a soft cloth — avoid hard brushes that scratch it. Re-seat after cleaning.

Purified tank: The built-in open 2L purified tank has an anti-clog screen and temperature sensor; open and clean it regularly. Clean every 1-2 months, rinse and wipe. Helix2.0 UV sterilizes on a 24h cycle for long-lasting inhibition.

Warming base: Splash-proof, but do not disassemble and soak. Rinse lightly or wipe to clean.

Waste Water

The S9 is Grade-1 efficiency, purified rate 65%, rated total purified 4,000L. The leftover raw-tank water is not true "waste" — it flushes debris off the filter surface and helps maintain filter life. When the machine prompts to change raw water, empty and refill before continuing.

Though not for drinking, waste water can be reused for cleaning or watering — no waste.

Cleaning & Descaling

Daily cleaning: ① Body: wipe with a soft damp cloth; no corrosive cleaners or steel wool; never immerse or hose the whole unit. ② Raw tank: remove every 1-2 weeks, rinse, wipe, avoid hard brushes. ③ Purified tank: remove the open tank (screen + sensor) every 1-2 months, clean, re-seat. ④ Tea chamber/filters: remove the basket and empty leaves after each brew, rinse the double filter and chamber. ⑤ Warming base: splash-proof but no soak; rinse/wipe only.

Pipe descaling: Over time the heater and pipes may scale due to water hardness; descale every 3-6 months (shorter in hard-water areas). ① Use Bewinch official descaler, mix per instructions into the raw tank. ② Run one purification + hot cycle so descaler flows through the heater and tea path. ③ Soak the required time, then drain all descaler. ④ Repeat purify-and-drain 2-3 times with clean water until taste/odor is gone before drinking.

Do not use strong acid/alkali or non-food-grade descalers; do not drink the hot water produced during descaling. If unsure of the descaling schedule or method, contact the store where you purchased for guidance.

FAQ

Tea Brew / Steep Questions

Why doesn't it pour tea automatically after brewing?

This is by design. After tapping "Tea Brew", it defaults to 500mL, heats to 100°C, and runs a 2-minute brew countdown. When done it stops heating automatically but does not pour — tap "Pour Tea" to drop the soup into your cup, so you control the timing.

What's the difference between Steep, Brew, and Slow-Brew?

Steep: low-temperature extraction (65-98°C, 1-5 min), pours automatically when done; suited to delicate green/scented teas.

Brew: true 100°C boiling (default 500mL, 2 min), pour manually after; suited to pu-erh/dark teas that need high heat and long brewing.

Wellness Slow-Brew: concentrated slow extraction for dark/white/black/scented tea (1-5 min) and lingzhi-cordyceps/dendrobium (10-30 min), for precious wellness ingredients.

Why does tea taste better with the S9?

The S9 filters strontium alkaline mineral water (around pH7.6) with strontium, calcium, magnesium, potassium, and more. Brewing with pure water tastes flat, while the mineral ions in strontium alkaline water raise polyphenol extraction by about 30%; alkaline slow-brewing also raises ginsenoside/cordyceps-polysaccharide release by about 44%, for a mellower soup and better nutrient release.

What is the rinse-tea function? Use it every time?

When enabled, it first rinses the leaves with 60°C, 100mL for 18 seconds to wash off surface dust. Choose per tea; the rinse water is not for drinking.

Water Quality Questions

White foam in the water?

White foam is normal — it is fine air bubbles that disappear at rest; safe to drink. During purification, pressure pushes water through the membrane and some air dissolves; it comes out as fine bubbles when pressure releases. As hot water cools, air solubility drops and bubbles appear.

What water does the S9 produce? What is strontium for?

The S9 produces strontium alkaline mineral water: raw water is first filtered to pure water, then mineralized by the Stage-3 Q2-Sr+ filter into water with strontium, calcium, magnesium, potassium, sodium, zinc, and metasilicic acid, around pH7.6. Strontium is an essential trace element that supports bones bidirectionally and helps immunity; alkaline water better extracts tea polyphenols.

A few water marks on the new unit?

Countertop purifiers are complex to make, so Bewinch runs 100% performance and water-safety checks before shipping. After testing, the water path is cleaned and test filters replaced with new ones; small water marks may remain in the pump and valves — normal. Just flush per the guide and use.

Operation Questions

How do I use the slide child lock?

The S9 uses a classic slide child lock, turned on/off in "General Settings - Lock Screen (Child Lock)". When on, slide to unlock before use, preventing pets/children from accidentally dispensing water or getting burned.

How do I set the 9 custom groups?

You can save 9 groups: 3 tea, 3 wellness slow-brew, 3 custom water. For tea, choose temp/time/volume, then tap "+" at the bottom to save. To change or delete, tap the delete icon; saved presets are one-tap recall.

Screen dims quickly?

This is normal eco mode. With eco on, the screen dims after 5 idle minutes to save energy; turn eco off in General Settings to keep it lit.

Filter Questions

How often to replace filters?

The S9 has three filters: Stage-1 composite and Stage-3 strontium alkaline every 6-8 months; Stage-2 RO membrane every 2-3 years. Actual life depends on power-on time, local raw TDS, and daily dispensing; the machine reminds you — follow the screen.

Not replacing on time lowers filtration, worsens taste, and in serious cases may cause secondary contamination or clog the booster pump.

How to reset after replacing?

When life ends, the screen shows 0% and beeps 10s at dispense. Turn the old filter lock→unlock and pull it out; insert the new one and turn back to lock; a beep and return to the main page means reset is done. If the screen doesn't change in 30s, re-seat the filter. Each chip resets once — wait for the system reminder before replacing.

Do filters have a shelf life? Is bulging packaging normal?

Unopened filters keep for 5 years; store in a cool dry place. Slight bulging of the outer bag is normal — units are filled with protective gas and heat-sealed for inspection at the factory. As long as the bag is intact and clean, it is safe to use.

After-Sales & Service

What is the S9 warranty policy?

The S9 enjoys a 4-year long warranty: years 1-2 offer "replacement-only" — quality issues are swapped for a new unit directly; years 3-4 offer nationwide warranty, with free repair for non-human-caused defects. For support, contact the store where you purchased.

Is 30-day no-reason return supported?

Yes, a 30-day no-reason return applies, provided the unit has not been connected to water, powered on, or installed, and accessories and packaging are intact. Units already connected to water or used cannot be returned without reason, due to water hygiene.

Do I need on-site installation?

The S9 is a non-plumbed countertop unit: just place it steadily, add tap water, and use — no water line needed. If you'd like a first on-site setup or filter-replacement guidance, book the first free on-site service via the Bewinch mini-program, or contact the store where you purchased.

Brewing

How do I use the tea pot?

Place the cleaned pot on the unit; ensure the pot bottom is dry before placing. In high-altitude areas, we recommend running a boiling-point check first. The system stops heating automatically past the heating or warming time; press "Reheat" to restart.

How to disassemble, clean, and descale the pot?

① After the pot cools, hold the handle with one hand and the inner lid with the other, lifting upward. ② Grip the lid and inner lid, turn counterclockwise to unlock, then lift out. ③ Remove the metal basket downward. Wash parts with warm water; never immerse the pot body. To descale: add white vinegar and rest 1 hour, or add 6.5g citric acid/baking soda with boiling water and rest 15 minutes, empty, then rinse 5-6 times.

How to turn off the 999 alert?

When raw TDS hits the 999 peak, a "change raw water" icon pops up. Long-press "Pour Tea/Stop" for 5s to mute/restore the 999 alert; touch any key to exit. Even with the alert off, we still recommend changing the raw water promptly.

Filters & Reset

How do filter-reset methods differ across series?

The G3 series uses NFC reset: long-press the filter-reset key 5s, then hold the new filter's anti-counterfeit tag near the NFC zone on the right side of the unit; a beep completes it. New N/Q-series units auto-reset by chip — the indicator returns to full after screwing in. Each filter chip resets only once.

Do filters have a shelf life?

Filters keep for five years; leave the bag sealed and store in a cool place — safe to stock up.

Use & Care

Why can't it reach 100°C (how to understand "true boil")?

The S9 uses simulated open-flame even heat and true-100°C brew-immersion; it reaches a rolling boil during tea brewing. Daily direct-dispense water is RO purified water meeting national direct-drink standards. In the sealed heating structure, ambient-level heating is usually held above 90°C and below 100°C to protect the pipes.

How to re-enable after 72+ hours unused?

Empty the leftover raw water and refill with municipal tap water; power on and drain the internal water; let the purified tank fill, then drain; repeat 3 times.

How to clean the purified tank?

Clean every 2-3 months: remove the raw tank, open the top cover, long-press "Dispense/Stop" 5s to drain, wipe the inside with a lint-free cloth, re-seat the raw tank, fill, then drain 2-3 more times.

Troubleshooting

Tea pot shows "E06"?

Symptom
During brewing the screen shows "E06" and the pot stops heating.
Cause
The pot has NTC self-protection; "E06" appears when the pot is too hot (e.g. dry-boiling or thermostat protection).
Solution
Empty the hot water, refill with cold, set the pot aside to cool, then place it back on the unit to clear.

Tea pot won't heat?

Symptom
After pressing brew/heat, the pot does not warm.
Cause
Possible: exceeded heating/warming time, or dry-boiling triggered thermostat protection.
Solution
① Press "Reheat" or redo the brew/reheat flow. ② If it is dry-boil protection (E06), empty hot water, add cold, let cool, and replace the pot. If it repeatedly won't heat, contact the store where you purchased.

Tea overflows while brewing?

Symptom
Tea spills out of the pot during brewing/steeping.
Cause
Possible: filled past the MAX line, or too much tea causing a concentrated soup that foams over.
Solution
① Keep fill within the MAX line (upper-cup chamber max 800mL; brewing fill stops manually, never over the line). ② Use less tea and brew again.

No water / no hot water?

Symptom
After pressing dispense, no water or no hot water comes out.
Cause
Possible: raw tank empty, purified tank at minimum, expired filter clog, child/lock screen not unlocked, or no temperature selected.
Solution
① Check raw tank and refill. ② Wait until the purified tank reaches a high level before dispensing hot. ③ Check filter life and replace if due. ④ Unlock child/lock screen. ⑤ Confirm a temperature is selected. If still no water, contact the store where you purchased.

Purified TDS stuck at 30 / shows H02?

Symptom
Purified TDS stays at 30, or shows H02.
Cause
Stuck at 30 usually means raw water was not changed; H02 usually means no dispense for 3 days.
Solution
① Change raw water and re-purify. ② Dispense once normally and H02 clears automatically.

Raw TDS shows 999 and alarms?

Symptom
Screen raw TDS shows 999 and the buzzer alarms.
Cause
Local water is poor or raw water wasn't changed in time, reaching 999.
Solution
① Change all raw water. ② Dispense so the unit purifies; TDS drops. ③ If hard water can't be improved, long-press "Pour Tea/Stop" 5s to mute (long-press again to restore; only when raw TDS reads 999).

Asks for filter replacement right after changing?

Symptom
After fitting a new filter, the screen still says expired or detection abnormal.
Cause
Possible: filter not fully screwed in, Spin-ID contact poor, or non-original filter.
Solution
① Remove and re-screw lock; if no change in 30s, re-insert. ② Use original Bewinch filters — non-original may not be recognized. ③ After changing, drain cold water 3 times to soak. If it still alerts, contact the store where you purchased.

Off taste / abnormal taste?

Symptom
Water tastes of plastic, disinfectant, or other off-flavor.
Cause
Possible: new unit under-flushed, expired filter, tanks not cleaned long-term, or raw water worsened.
Solution
① Complete the full flush (cold drain 3-5x + 45°C flush 1-2x + 98°C flush 1-2x + tea-path clean 1-2x). ② Check/replace filters. ③ Clean purified and raw tanks. ④ If raw water suddenly worsened, change all raw water first.

High altitude: water won't reach 100°C?

Symptom
At high altitude, brew/heating water temp is low and won't reach 100°C.
Cause
Low air pressure at altitude means boiling water cannot reach 100°C.
Solution
Run a manual boiling-point check: place the pot on the unit, long-press "Tea Brew/Stop" 5s while the purified tank is full; it auto-fills, heats, and detects the boiling point, then beeps three times and enters standby. The unit records the local boiling point.

Fault light on after long unused?

Symptom
The fault indicator lights up after long storage.
Cause
Normal reminder caused by residual water changing after long sitting.
Solution
No need to worry — press "Start" to dispense normally, or run one drain cycle to recover. Before reusing after long storage, run a full drain/flush and clean the purified and raw tanks.

Scale on the raw-tank wall?

Symptom
White powdery crystals form on the raw-tank wall over time.
Cause
Water hardness varies by region; long use forms scale on the wall.
Solution
① Take a cup of ~65°C hot water, add 5-10g food-grade citric acid, stir to dissolve. ② Fill the raw tank with tap water, pour in the citric solution. ③ Soak 30-60 min, wipe the wall with a clean cloth until scale comes off. ④ Empty and rinse with clean water.

Tea pot dry-boil protection?

Symptom
After an accidental dry-boil or overheating, the temperature sensor triggers overload protection — usually 2-3 lights flash together and keys lock.
Cause
Continued heating when the lower pot's water level was too low, causing dry-boil.
Solution
Press the lower pot firmly downward, unplug, and restart to clear the alarm. Note: when the lower pot level is low, remember to turn off heating, or dry-boil can damage the unit's chip.

Can't dispense while steeping?

Symptom
While a brew/steep program runs, you can't dispense ambient or hot water at the same time.
Cause
By the program's design, with a single heater and power limits, hot dispensing during steeping is difficult.
Solution
Wait for the program to finish, or interrupt it, then dispense. Ambient water usually dispenses normally.

How to clean the upper cup / tea filter?

Symptom
The all-in-one brew unit needs the upper cup and tea filter cleaned after use.
Cause
Tea residue and scale buildup need regular cleaning.
Solution
Follow the upper-cup cleaning video; regularly remove the filter and rinse; soak the upper cup in citric solution to descale.

Tea spout drips?

Symptom
The tea spout drips during brewing/steeping.
Cause
A foreign object jams the upper-cup valve.
Solution
Clean the upper-cup valve and remove the object.

Slow / skewed tea flow?

Symptom
Tea flows slowly or off to one side.
Cause
① object jamming the spout; ② object jamming the upper-cup filter.
Solution
① Remove the spout guide tube and clean. ② Clean the upper-cup filter.

Lower cup not keeping warm?

Symptom
Tea in the lower cup cools quickly.
Cause
The drip tray is loose or the warming switch is off.
Solution
Re-seat the drip tray and turn on the warming switch.

E01 code?

Symptom
Screen shows E01; the unit stops dispensing and purifying.
Cause
Inlet water-temp sensor abnormal, usually from very low ambient (often winter); the sensor sees ~0°C and self-protects.
Solution
Move the unit to a warm room for 1-2h; it clears when the sensor recovers. If it still won't clear in warmth, it may be a sensor or control-chip fault — contact after-sales.

E02/E03/E04 codes?

Symptom
E02 (pops when dispensing hot water), E03 (outlet temp sensor short), or E04 (outlet temp sensor open).
Cause
Inlet/outlet temp sensor abnormal, or the outlet NTC cracked and took in moisture.
Solution
Restart and observe; if it recurs, contact after-sales to inspect the temp sensor.

E07 drain abnormal?

Symptom
Screen shows E07.
Cause
Continuous draining for 10 minutes still not complete.
Solution
Power off to clear; check the drain line for blockage; contact after-sales if it recurs.

E11 heating fault?

Symptom
Screen shows E11.
Cause
After 20s of heating it still hasn't reached half the target temperature.
Solution
Power off to clear; use 5°C-35°C tap water; contact after-sales to inspect the heating system if it recurs.

H01/H02 drain prompts?

Symptom
Screen shows H01 or H02.
Cause
H01 = no hot-water dispense for 3+ days; H02 = unused for over 72 hours.
Solution
Long-press "Dispense/Stop" ~5s to drain; H02 clears once drained to low level. When re-enabling, empty the raw tank, refill, and repeat draining 3 times.

No hot water / slow heating?

Symptom
Selecting hot gives no hot water, low temp, or slower heating.
Cause
① low boiling point at altitude; ② heater not recovered after heavy continuous dispensing; ③ filter clog; ④ not preheated just after startup; ⑤ raw water too cold.
Solution
① re-run boiling-point check at altitude. ② wait 3-5 min after continuous dispensing. ③ replace due filters. ④ dispense one cup first to warm the pipes. ⑤ use 5-35°C raw water.

Steam/sputter when taking hot water?

Symptom
High-temp dispensing sputters or sprays steam.
Cause
At high altitude the boiling point drops and there is lots of steam in the heating tube.
Solution
Keep the container near the spout when taking hot water; beware splashing during the true-100°C brew.

Leakage under the unit?

Symptom
Water pooling under the unit or ongoing leak.
Cause
① raw tank overfilled past the max line; ② bottom inlet/outlet valve loose or scaled; ③ filter not tightened; ④ internal pipe joint loose.
Solution
① check water level. ② press/turn the bottom inlet/outlet valve. ③ re-tighten filters. ④ for internal leaks, cut power immediately and contact after-sales — do not open the unit yourself.

Spout drips (new unit)?

Symptom
The new unit's spout drips continuously.
Cause
Debris in the water path prevents the valve from closing fully.
Solution
Drain several times to flush out debris; if it still drips, contact after-sales.

Noise / unusual sound?

Symptom
Noticeable noise or rattling while purifying or heating.
Cause
① raw tank empty, pump running dry; ② not level; ③ filter not seated; ④ a slight pump sound is normal.
Solution
① check water level. ② level the surface. ③ check filters. ④ for obvious rattling/vibration, contact after-sales to inspect the heater or diaphragm pump.

Screen dark / touch unresponsive?

Symptom
Screen black or all keys unresponsive.
Cause
① power not connected; ② screen module fault.
Solution
① check plug and outlet. ② if all keys fail, contact after-sales to replace the screen module.

Purified-water light red / anti-overflow alarm?

Symptom
The purified-water light turns red, prompting anti-overflow.
Cause
Purified tank not installed correctly or poor contact.
Solution
Re-seat and press the purified tank firmly; draining cancels the anti-overflow.

Raw TDS lower than purified TDS?

Symptom
Raw TDS reads lower than purified TDS.
Cause
① pure water poured into the raw tank; ② new unit under-flushed; ③ raw water too pure, little RO waste.
Solution
Use municipal tap water and complete flushing; after a week with higher-TDS tap water the raw value will exceed the purified value — normal.

Strong odor / new-unit smell?

Symptom
Off taste, or new-unit smell still strong after airing.
Cause
① new unit under-flushed; ② expired filter; ③ tanks long uncleaned.
Solution
① complete the full flush. ② replace due filters. ③ clean raw and purified tanks; leave the purified tank open 24h.

Green algae in the tank?

Symptom
Green moss-like growth on the tank wall.
Cause
Green algae grows where there is light.
Solution
Place the unit out of direct light; soak and clean with citric solution.

Moved the tank while purifying → leak?

Symptom
After moving the tank mid-purification, air-lock and leakage.
Cause
Moving the tank while purifying lets air into the water path.
Solution
Don't move the tank while purifying; wait until purification finishes or it prompts a water change.

Insects in the unit?

Symptom
Insects found inside or under the unit.
Cause
The base drainage holes can admit insects when they are abundant.
Solution
Place it in a clean, ventilated, dry spot; put insect-repellent sachets around the feet. The internal water path is fully sealed and doesn't affect water quality.

Tips & Self-Help

Slow / no / intermittent purification — suspected air-lock

Symptom
Slow purification, no water, or intermittent flow — suspected "air-lock".
Solution
① Power on and wait until it purifies (you'll hear "putt-putt"); when done, open the top cover and pull out the filters. ② Use a chopstick to gently poke the holes at the bottom of each filter to release air (note: if the chopstick meets resistance, it confirms an air-lock — water may spray from the filter bottom, so never point it at your face). ③ Vent each filter in turn, re-seat them, wipe the table, close the cover — ready to use.

Plastic/odd smell after new unit or water change, even after flushing

Symptom
Off/plastic taste after a new unit or water change, persisting through flushing.
Solution
① Open the top cover and purified-tank lid, leave open 24h to air out. ② If still present, brew food-grade citric acid, pour into the purified tank to soak, then drain/rinse 2-3 times. ③ Ensure the full flush (cold drain 3-5x + warm flush 1-2x) is completed.

Spout still drips a few drops after removing the cup

Symptom
The spout still drips a few drops after the cup is removed.
Solution
New-unit dripping is usually residual carbon powder/debris in the path; drain a few more times (3-5x) to normalize. If it keeps dripping after a while, contact the store where you purchased.

White floating particles in dispensed water

Symptom
White floating particles in the water.
Solution
After a new unit or filter change, residual food-grade grease in the path may wash out — normal. After a few more cups (5-10) it clears; harmless and safe to drink.

Jumping screen / flaky touch

Symptom
Screen numbers jump; touch is unresponsive or intermittent.
Solution
① Wipe water off the screen — capacitive touch misfires when wet. ② Check for unstable voltage; try a separate outlet. ③ If it still jumps/flickers, it may be a touch-film fault — contact after-sales to replace.

Dispense key gives no water but the display looks fine

Symptom
Pressing dispense gives no water, though the display looks normal.
Solution
① Check the top cover is fully pressed down (an unsecured cover triggers a safety lock). ② Power off 1 minute, then back on. ③ Confirm the raw tank has water and the float rises normally. ④ If none work, it may be a diaphragm-pump 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" 5s to drain; it stops automatically. ③ Wipe the purified-tank wall with a clean lint-free cloth. ④ Refill the raw tank and let it purify. ⑤ Long-press to drain 2-3 more times — ready to use.

Intermittent hot flow with steam

Symptom
Hot water comes out intermittently with steam.
Solution
On units with swirl-speed instant heating, water hits ~100°C in the tube and produces lots of steam, so the stream is thinner than ambient and may fluctuate — normal. At low altitude/boiling point it looks similar; try 85°C.

Insects under/around the unit

Symptom
Insects found under or around the unit.
Solution
The base has drainage holes for safe draining and can admit insects. Fix: ① place the unit in a clean, tidy, ventilated, dry spot and clean regularly. ② put 1-2 non-toxic repellent sachets around each of the four feet. The internal path is fully sealed and doesn't affect water quality.

Plastic smell after flushing — how to deeply de-odorize

Symptom
Plastic smell remains after flushing — how to de-odorize deeply?
Solution
Water-contact plastic parts are de-odorized at the factory, but sealed packaging may leave a slight plastic smell — normal. The usual method is to leave the purified tank open 12-24h, then complete flushing. If still present, use the "dish-soap method": dilute food-grade dish soap, pour into the purified tank, circulate, then drain repeatedly 3-5 times with clean water. See the official video for details.

White scale/crystals on the raw-tank wall

Symptom
White scale/crystals appear on the raw-tank wall.
Solution
White powdery scale can appear on long-used tanks — normal. To descale: ① a cup of ~65°C hot water, add 5-10g food-grade citric acid (adjust by severity), stir to fully dissolve. ② Fill the raw tank, pour in the solution. ③ Soak 30-60 min. ④ Wipe the wall with a clean cloth until scale comes off. ⑤ Empty and rinse with clean water.

Bulging outer packaging on a new filter

Symptom
The new filter's outer bag is swollen/bulging.
Solution
Normal. Filters are air-tested and gas-sealed before leaving the factory to preserve condition and filtration, so the bag may bulge. As long as the seal is intact, it's safe. Bewinch uses double heat-seal bags to keep filters clean in transit.

Loud purification noise on first use

Symptom
First use: purification is very loud.
Solution
Normal. New filters and pump hold lots of air; the booster pump makes noise compressing it. Repeated purify-and-drain soaks the path and the noise gradually drops. If still loud, check the unit is on a flat table; put a soft flat mat under it to reduce resonance.

Black powder in raw/purified tank on first water-through

Symptom
Black powder appears in the raw or purified tank when water first passes through.
Solution
Normal. Activated-carbon filters are sintered from carbon powder + food-grade binder; a new filter sheds a small amount on first use — non-toxic. If raw tank: flush the new unit 3-5 times. If purified tank: rinse lightly with tap water, wipe with a clean cloth, then drain/rinse a few more times.

Murky raw water with green/brown floating bits

Symptom
Raw-tank water looks murky with green or brown suspended matter.
Solution
This is usually algae spores or pipe sediment from aging tap-water mains, more visible in summer. The raw tank holds unpurified tap water; murkiness does not affect the output — after the RO membrane (0.0001µm pores) filters out microbes, bacteria, and debris, the water is safe to drink directly. Clean the raw tank regularly.

Leakage under/around the unit

Symptom
Leakage found under or around the unit.
Solution
① Close the inlet valve (if any), stop supply, and cut power. ② Self-check: see if water spilled while dispensing, or the raw tank exceeded MAX. ③ Open the top cover, check all three filters are seated, remove and re-align each. ④ Wipe the table and unit bottom, then power on and observe. If it leaks repeatedly, contact the store where you purchased.

What is TDS?

Symptom
What is TDS? Why does the number differ each time?
Solution
TDS (Total Dissolved Solids) is the total amount of dissolved matter in water; higher means more minerals/impurities. It depends on the raw water you add, not a fixed value. Residual old water in pipes/filters mixes with new water, so the reading may run slightly above tap water. After changing raw water, dispense a cup so the unit purifies and the TDS probe updates to the new water.

Why leftover raw water gets more concentrated / "waste water"

Symptom
Why does leftover raw water get more concentrated / what is "waste water"?
Solution
RO membrane precision is 0.1nm; to keep impurities from clogging the pores, some water flushes the membrane surface and returns to the raw tank as "waste." It is only slightly saltier than tap water, not sewage. Each water change, empty all leftover raw water and refill fresh; don't reuse waste water.

Volumetric dispense is slightly off

Symptom
Volumetric dispense is slightly low or high vs a measuring cup.
Solution
A little water stays in the path, so some volumetric error is normal. Hot-water deviation may be a bit larger because flow speed changes with water temp. Use an accurately marked cup/bottle; this is within normal tolerance.

A vertical line/mark on the casing

Symptom
A vertical line/mark on the casing.
Solution
This is a mold-flow line that naturally forms where plastic fuses during injection molding — common industry-wide; it does not affect use or looks. We keep refining the process to minimize it.

How is filter-life calculated?

Symptom
How is filter-life calculated? Must I replace when it says so?
Solution
Filter life is computed three ways: ① power-on time (like a shelf life — it decays over time even unused after activation); ② raw-TDS change (worse water consumes faster); ③ cumulative dispensing (more use = faster). The reminder is a recommended cycle, not a hard deadline, but don't wait until the filter fully clogs, or the booster pump may overload or a pipe may burst.
