Placement & Setup

The M3 Pro Huyun is a no-install countertop unit — add a drinkable ambient water source and it's ready. Placement must meet:

Placement Requirements

1. Put it on a well-ventilated, level, stable counter, out of direct sun and away from heat.

2. Leave ventilation space around it and a gap behind the unit.

3. The counter must support about 3.6 kg, with a matched 3-hole outlet nearby.

4. Leave room to remove and fill the raw tank.

Acceptable Water Sources

Boiled-cooled, purified, mineral, distilled, or filtered drinkable ambient water can go in the raw tank. We recommend bottled or already-purified drinking water. In areas with heavy or hard water, choose a Bewinch G-Series RO unit. Inlet water must be 5°C-35°C.

New-Unit Flush Guide

Before first use, flush to activate the filters and clean the lines. The unit and filters may carry a slight factory smell — the more you flush, the better the taste.

Flush Steps

1. Air out: Unbox the unit and parts, remove the raw tank, top cover, and purified tank, and air them in a cool, ventilated, dry place for 12-24 hours.

2. Start filtration: Fill the raw tank to the max line, refit the purified tank and top cover, plug in, and wait until the purified-water level lamp shows normal.

3. Ambient drain (×3): Place a container over 3.5L under the spout, run a drain/dispense to empty the purified tank, repeat 3 times to fully soak the filters.

4. 45°C flush (×1-2): Select 45°C and dispense warm water until the purified tank is empty; repeat 1-2 times.

5. 98°C flush (×1-2): Select 98°C and dispense hot water until empty; repeat 1-2 times. Beware of high heat.

6. Done: The unit is ready. For the first 3 days, drain once a day to fully activate the filters.

04

Daily Use

Dispensing Water

Ambient / Warm / Hot Dispensing

1. Confirm the raw tank has water and the purified tank is ready.

2. Press "Temp" to choose a level (7: ambient / 45°C / 55°C / 65°C / 75°C / 85°C / 98°C).

3. Press "Volume" to choose a preset (2 levels).

4. Press "Dispense/Stop" to start; it stops automatically at the set volume.

5. Press "Dispense/Stop" again to stop early.

The unit remembers the last temperature and volume and restores them next time.

85°CCoffee, oolong, black tea
98°CBoiling: noodles, tea, soup, porridge

Volume presets are 100mL / 200mL with auto-stop. When dispensing hot water, avoid scalding; children use it under adult guidance. After 72 hours unused the screen shows H2 — long-press "Dispense/Stop" for 5s to drain before use.

Smart Features

Clear Digital Display

The panel clearly shows raw/purified status, filter life, and temperature/volume levels.

Smart Filter-Life Indicator

The panel shows each filter's remaining life in real time. When a filter lamp shows empty with a beep, it is time to replace it.

Placement & Tank Refill

No-Install Placement

Unbox, add water, and plug in. The compact body fits a kitchen counter, bedroom, study, office, or sideboard — fully portable, ideal for renters.

Refilling the Raw Tank

The 3L raw tank is quick-release. When low, lift it out, fill with matched tap water (5-35°C), and refit. Clean the raw tank every 1-2 weeks.

Replacing Filters

Self-Replacement Steps

1. When the screen shows a filter expired, prepare the matching original filter.

2. Open the top cover; turn the filter from "Lock" to "Unlock" and lift out the old one.

3. Unbox the new filter, insert it in the marked direction, and turn from "Unlock" to "Lock" until tight.

4. Refit the cover, power on, and wait for auto recognition/reset.

5. After replacement, drain/flush 2-3 times to soak the new filter.

No technician needed — twist and lift. Use only Bewinch original filters. Each filter chip resets only once; replace when the indicator prompts.

Daily Cleaning & Descaling

Cleaning the Tanks & Body

Raw tank: Quick-release; clean every 1-2 weeks. Rinse with water, wipe with a soft cloth — avoid hard brushes.

Purified tank: Clean every 1-2 months; rinse and wipe.

Body: Wipe with a soft dry or slightly damp cloth; avoid corrosive cleaners and hard scourers; never immerse or spray the whole unit.

Descaling

The ion-exchange resin already reduces scaling. If scale forms after long use, descale every 3-6 months:

1. Add warm water to the raw tank and dissolve food-grade citric descaler.

2. Run the unit to circulate the solution through the heat lines.

3. Soak 15-30 minutes, then drain.

4. Refill with clean water and drain-flush 3+ times to remove all descaler before use.

Use food-grade citric acid only — never strong acids or corrosive cleaners. After 72h unused, empty the raw tank, refill, and fully drain 3 times before use.

FAQ

Water Quality

White foam in the water?
WaterFoamBubbles

White foam is normal — it is fine bubbles that disappear at rest. Two causes: (1) pressure change dissolves air, which releases as bubbles when dispensed; (2) hotter water holds more air, which comes out as it cools. It is safe to drink.

Off taste / plastic smell on first use?
TasteOdorNew Unit

A slight plastic smell on first use is normal. Complete the full flush (3 ambient drains + 1-2 at 45°C + 1-2 at 98°C). If the smell persists after use, check whether a filter is expired or a tank has not been cleaned in a long time.

Why ultrafiltration (UF) instead of reverse osmosis (RO)?
FiltrationUFBacteria

The M3 Pro Huyun is an entry UF purifier focused on bacteria-free fresh water — it removes 99.99% of microbes while keeping minerals, with no waste water and no concentrate. If you need RO water that removes heavy metals and scale more thoroughly, see the Bewinch G- or Q-Series.

Operation

How do I choose temperature and volume?
OperationTempVolume

Press "Temp" to cycle the 7 levels, "Volume" to choose one of 2 presets, then press "Dispense/Stop" — it stops at the set amount. The unit remembers your last settings.

How do I replace a filter?
OperationFilterReset

Open the top cover, turn the old filter from "Lock" to "Unlock", fit the new one and turn "Unlock" to "Lock", then power on for auto recognition. Drain-flush 2-3 times after.

Filters

How often do filters need replacing?
FiltersLifeCycle

The composite filters are recommended about every 6-8 months. Actual life depends on power-on time, local raw water, and daily dispensing — follow the screen indicator. Delayed replacement reduces filtration and taste and may cause secondary contamination.

Do new filters expire? Is a swollen bag normal?
FiltersShelf LifeSwelling

Unopened filters have a 5-year shelf life — store in a cool, dry place. Slight swelling of the outer bag is normal: filters are sealed with protective gas after air-tightness testing. As long as the bag is intact and clean, it is fine to use.

Use & Care

What water can I put in the raw tank?
TankRaw WaterFill

Use 5-35°C tap or purified water. Never add hot/ice water, drinks, sewage, or other liquids, which can damage filters and the unit. Refresh the raw water regularly to avoid bacterial growth.

Does the purified tank need cleaning?
CleanTankCare

Clean the purified tank every 2-3 months with a neutral detergent and soft cloth, rinse, and dry before refitting. For scale in the raw tank, soak 30-60 minutes in 5-10g citric acid dissolved in 65°C water, then rinse.

After-Sales

What is the warranty policy?
WarrantyServiceReplace

The M3 Pro Huyun carries a 2-year national warranty: in year 1, quality faults (non-user-caused) are replaced with a new unit; in year 2, non-user-caused faults are repaired free. For support, contact the store where you purchased.

Do I need on-site installation? Returns?
InstallReturnsService

No installation needed — place it steadily and add water. For any return or exchange, contact the store where you purchased, as returns depend on the store's policy and the unit's condition.

Does the stage-3 resin filter need a reset?
Filter 3ResinReset

No. The stage-3 ion-exchange resin filter in the raw tank adjusts mineral taste and is not part of the main-unit reset counter. Only the in-unit stage-1 PP and stage-2 UF/carbon filters need resetting when prompted.

How do I manually reset filters?
FilterResetManual

This UF unit uses manual reset: long-press "Temp" for 5s to enter filter selection, short-press to switch filters, then long-press the hot-unlock key for 3s to complete the reset.

Why no waste water with UF?
UFNo Waste

UF filters at 0.01µm using natural tap pressure — no booster pump or RO membrane — so no concentrate waste water and no drain line needed; just add water.

Why does it heat in 3 seconds?
Instant HeatSpeed

The instant-heat element heats on demand — dispensing reaches the set temperature in 3 seconds, with no long preheating or keeping warm.

Why doesn't it reach 100°C?
TempBoilingHeating

To avoid overpressure in a sealed heat line from boiling, the unit heats to 90-100°C. The water is deeply filtered to drinking standard, so it is safe to drink without a rolling boil.

What to do before using a new unit?
New UnitFlush

Air it out, fill the raw tank and power on, drain ambient water 3-5 times, then flush 1-2 times at 45°C and 98°C. The more you flush, the better the taste.

Is water residue on a new unit normal?
New UnitWater Marks

Every unit is 100% water-tested before shipping, so a little residue in the pump/valves is normal.

What to do after 72+ hours unused?
IdleRestart

Empty the raw tank, refill with tap water, fully drain the unit's internal water, refill, and drain again — repeat 3 times before use.

How to place the compact M3 Pro?
PlacementCompact

It is a compact countertop unit, plug-and-play, no install. Put it on a stable, dry, level surface, out of direct sun and humidity, with a ventilation gap behind.

How do I book after-sales repair?
ServiceBookRepair

Scan the mini-program QR code on the unit, choose "Installation/Repair" and submit, or call the national service hotline 400-828-0808. Within the first year, non-user-caused faults are replaced rather than repaired.

What to do in an emergency leak?
LeakEmergencyPower Off

Cut power and stop the water supply immediately, locate the leak, and contact official support — never disassemble the unit yourself.

07

Troubleshooting

No water dispensed?

Symptom
No water or slow flow after pressing dispense.
Cause
Raw tank empty, purified tank not full, filter clogged/expired, or no temperature/volume selected.
Solution
Check raw-tank level and refill; wait for the purified tank to fill; check filter life and replace if due; confirm a temp/volume is selected. If still no water, contact the store where you purchased.

Unit leaking?

Symptom
Water pooling under or around the unit.
Cause
Raw/purified tank not seated, worn/moved tank seal, or overflowing drip tray.
Solution
Refit both tanks until they click; check the seals; empty the drip tray. If it still leaks, cut power immediately and contact the store where you purchased — never disassemble it.

Not hot enough?

Symptom
Set high but the water is warm, or heating slows down.
Cause
Continuous large draw without letting the heater recover, a clogged filter, or a cold start not preheated.
Solution
Wait 3-5 minutes after a long draw for the heater to recover; check filter life; draw one cup first to preheat the line. If still abnormal, contact the store where you purchased.

Off taste / abnormal flavor?

Symptom
Plastic, disinfectant, or other off taste.
Cause
New unit not flushed, expired filter, long-uncleaned tank, or deteriorated raw water.
Solution
Complete the full new-unit flush; check/replace filters; clean both tanks; if raw water suddenly worsened, replace all raw water.

Noisy / unusual sound?

Symptom
Noticeable noise while filtering or heating.
Cause
Raw tank empty causing dry run, unstable placement, filter not seated, or normal pump hum (a soft hum is normal).
Solution
Check raw-tank level and refill; level the unit on a flat surface; open the cover and check filters. A soft pump/heat sound is normal. If there is strong noise or vibration, contact the store where you purchased.

Shows filter expired after replacement?

Symptom
Screen still shows expired after fitting a new filter.
Cause
Filter not seated, chip contact issue, or non-original filter.
Solution
Refit the filter until tight; wait 1 minute for chip recognition (do not twist during this); use a Bewinch original filter. If it still alerts, contact the store where you purchased.

Fault light on after long idle?

Symptom
The fault lamp lights after a long idle.
Cause
Normal reminder from changed residual water quality after long standing.
Solution
No worry — just press "Dispense/Stop" to draw a cup, or run one drain, and it returns to normal. After a long idle, do a full drain-flush before use.

New filter bag swollen?

Symptom
The outer sealed bag of a new filter is swollen.
Cause
Filters are inflated and sealed for air-tightness testing and better flow.
Solution
Normal. Bewinch uses double-sealed bags; as long as the seal is intact, it is safe to use.

Scale on the raw-tank wall?

Symptom
White powery crystals on the raw-tank wall after long use.
Cause
Water hardness varies by region and deposits scale over time.
Solution
Dissolve 5-10g food-grade citric acid in a cup of ~65°C water, fill the tank, soak 30-60 min, wipe with a clean cloth until the scale lifts, then rinse thoroughly.

Screen dark / touch unresponsive?

Symptom
Black screen or no touch response.
Cause
No power, child/screen lock on, or a temporary system hiccup.
Solution
Check the plug and outlet; unlock the screen if locked; long-press power for 10s to restart. If the screen stays dark, contact the store where you purchased.

E01 error code?

Symptom
Screen shows E01 and the unit stops dispensing/filtering.
Cause
Inlet-water temperature sensor abnormal; usually caused by a very cold environment (common in winter). At around 0°C the unit self-protects.
Solution
Move the unit to a warm room for 1-2 hours; E01 clears once the sensor recovers. If it does not clear in a warm room, the sensor/control board may need service — contact support to book a technician.

White foam / cloudy water on first draw?

Symptom
White foam or a cloudy look when first drawing purified water.
Cause
The pump compresses air in the water into fine bubbles, giving a "cloudy" look.
Solution
Normal physics, safe to drink. Bubbles clear at rest and fade after a few flushes as air leaves the lines.

Drip tray full / needs cleaning?

Symptom
The drip tray overflows or gets dirty.
Cause
Splashes and line residual water collect in the tray and need periodic emptying.
Solution
Remove the tray as shown, empty and rinse it, then refit. Check and clean regularly.

Slow flow / less water?

Symptom
Noticeably reduced output.
Cause
Filter past its life or clogged; raw tank empty.
Solution
Fill the raw tank; check filter life and replace as prompted. If still slow after replacement, contact support.

No hot water?

Symptom
Only ambient water when a hot setting is selected.
Cause
Hot temp not selected before dispensing; purified tank too low; hot-unlock not pressed.
Solution
Select a hot temperature first; wait until the purified tank has enough water; press the hot-unlock key to enable hot water.

Steam/splutter when dispensing hot water?

Symptom
Steam or splutter while dispensing high-temperature water.
Cause
At high altitude the boiling point drops and more steam forms in the heat tube.
Solution
Hold the cup close to the spout; watch for splutter on first use at high altitude.

Reset fails after filter change?

Symptom
Indicator still blinks after a new filter and does not return to full.
Cause
This UF unit needs manual filter reset; auto sensing does not apply.
Solution
Long-press "Temp" 5s to enter filter selection, short-press to the right filter, then long-press the hot-unlock key 3s to reset. Note: the raw-tank stage-3 resin filter needs no reset.

Filter life draining too fast?

Symptom
Filters wear out sooner than expected.
Cause
Power-on time counted; poor raw water; frequent dispensing.
Solution
Filter life is a recommended cycle, scheduled by actual use. Do not wait until it is fully clogged before replacing.

Leak after a filter change?

Symptom
Seepage under the unit after a filter change.
Cause
Filter not tightened or seated.
Solution
Reopen the cover and turn the filter to the locked position until it cannot be pulled out. Use an original filter.

Spout dripping after closing?

Symptom
The spout keeps dripping after closing.
Cause
Debris in the new-unit line prevents the valve from sealing.
Solution
Drain several times to flush the lines; if it still drips, contact support.

Buttons unresponsive under child lock?

Symptom
No dispensing button responds; screen shows child lock / LOC.
Cause
Child lock is on.
Solution
Long-press the child-lock key 5s to turn it off; it resumes after a beep. Child lock is off by default after a power restart.

Green film / algae in the tank?

Symptom
Greenish film on the tank wall.
Cause
Algae spores from air grow in well-lit water.
Solution
Move the unit out of direct light; soak and clean the tank wall with citric-acid solution and clean it promptly.

Insects in the unit?

Symptom
Insects found under the unit.
Cause
The base has drainage vents; insects may enter when the environment has many.
Solution
Keep the area ventilated, dry, and clean. The internal water path is fully sealed, so water quality is unaffected.

Water residue in the new pump/lines?

Symptom
A little water inside the new unit on unboxing.
Cause
Residue from the pre-shipment performance water test.
Solution
Normal; just flush and use.

Useful Self-Help Tips

Slow/on-off filtration suspected "air trapped"

Wait until filtration starts (the pump hums), open the cover and lift out the filter; gently poke the hole at the filter bottom with a chopstick to release air (do not point the bottom at your face — water may spurt out). Repeat for each filter, then refit and close.

Persistent plastic smell after flushing

Open the cover and purified-tank lid and air 24h. If still present, dissolve food-grade citric acid in the purified tank, soak, then drain-flush 2-3 times. Ensure the full new-unit flush is done (cold drain 3-5 times + warm flush 1-2 times).

A few drips after removing the cup

Usually residual carbon powder/debris in a new line — drain 3-5 times and it settles. If it keeps dripping after use, contact the store where you purchased.

White floating particles in water

Food-grade lubricant in a new line may flush out — harmless. It disappears after 5-10 cups; safe to drink.

Flickering digits / intermittent touch

Dry the screen (capacitive touch misfires when wet); try a separate outlet in case of unstable voltage; if it still flickers, the touch film may need replacing.

Dispense does nothing though the display is normal

Check the top cover is fully closed (an unlatched cover triggers a safety lock); power-cycle 1 minute; confirm the raw tank has water and the float rises. If none works, the diaphragm pump may be faulty — contact support.

Intermittent flow with steam on hot water

With swirl instant heat, water flashes near 100°C in the tube and makes steam, so the hot flow looks thinner and may fluctuate — normal. At high altitude, try 85°C.

Deep deodorizing after flushing

A slight residual smell after sealed packaging is normal; air the purified tank 12-24h then flush. If needed, circulate diluted food-grade dish soap through the purified tank, then drain with clean water 3-5 times.

Black powder in the tank on first water

Carbon filters are sintered with food-grade binder, so a little carbon powder flushes out initially — non-toxic. Flush 3-5 times; wipe the purified tank with a clean cloth and drain again.

Turbid/green-brown raw water

Usually algae spores or pipe sediment from an aging water network, worse in summer. The raw tank holds unfiltered tap water, but the UF membrane removes microbes and impurities, so output water is safe. Clean the raw tank regularly.

What is TDS? Why does it vary?

TDS (total dissolved solids) is the total dissolved material; higher means more minerals/impurities. It is set by the raw water you add, not fixed. Residual old water mixing with new can read a little high; after adding water, draw a cup so the TDS probe samples the new water.

Why doesn't it reach 100°C?

Heating is capped below boiling to avoid overpressure in a closed line. The water is filtered to drinking standard and is safe without boiling.

Inaccurate preset volume

A little residual water in the line makes preset volume slightly under/over — normal, a bit more for hot water as flow changes with temperature. Use a marked cup to measure; this is within tolerance.

How is filter life calculated? Must I replace on time?

Filter life combines: (1) power-on time (degrades even unused), (2) raw-water TDS (worse water = faster use), (3) cumulative dispensed volume. The prompt is a recommendation — but do not wait until it is fully clogged, which can overload the pump or rupture a line.
