Placement & Setup
The Q5 is non-plumbed — connect to municipal tap water to produce water; no inlet/outlet hose needed. Placement requirements:
1. On a well-ventilated, level, stable counter; avoid direct sun and heat sources.
2. Body ~273W × 212D × 362H mm — leave room for the jug.
3. Near a matching 3-pin socket (220V~ 50Hz, ≥10A).
4. Above 1,500 m altitude, do not dispense 98°C hot water to avoid scalding from steam.
Use municipal tap water (inlet 5-35°C). Purified or mineral water is also fine. Never add hot, iced, or unclean water.
1. Confirm jug, raw tank seated, and all three filters tightened.
2. Fill raw tank with tap water and replace.
3. Confirm voltage matches the rating plate, power on, then follow the new-unit flush below.
New-Unit Flush Guide
Before first use, flush to activate filters and clean the path. Units/filters may carry a slight odor — flush thoroughly; the more you flush, the better the taste. Takes ~30-40 min.
Unbox, remove raw tank, jug, and jug lid; air 8-12 h in a cool, ventilated, dry place (adjust for actual odor).
Replace the jug, fill the raw tank with tap water, power on. When the water-drop icon appears, wait ~10 min until the purified-volume light goes out.
Remove the jug, empty purified water, reinsert, repeat 3 times to fully soak and activate filters.
Place a ≥3.5L container under the outlet, press "Temp" to 45°C, press "Dispense/Stop"; the red light is on — wait for auto-stop, repeat 1-2×.
Press "Temp" to 98°C, press "Dispense/Stop"; wait for auto-stop, repeat 1-2×. Handle hot water carefully to avoid scalding.
The unit is ready. For the first 3 days, drain once daily to fully activate filters.

Smart Features
Place a heat-resistant container under the outlet, long-press "Custom/Clean" 5s. The unit cleans 30s (red light on) and drains 100mL of 98°C hot water, then auto-stops and resumes. Press again to cancel. Run after 3+ days idle; must run after producing water (not while producing).
The jug has a built-in UV lamp on auto-cycle. With the lamp off, press the child-lock key to start manual UV for 10 min. Manual mode does not affect the auto program.
Long-press "Child Lock" 5s; when you hear a beep, LOC shows at raw TDS and the unit cannot dispense/drain — preventing kids/pets from scalding or flooding. Repeat to unlock (LOC clears). Child lock defaults off after power-on/restart.
Long-press "Temp" 5s; beep, screen off = eco. Press any key to restore. The screen also auto-dims after 1 min idle.
The screen shows live raw/purified TDS. When raw TDS hits 999 and alarms, change ALL raw water and dispense/produce — TDS drops. Long-press "Volume" 5s to silence (again to restore).
Placement & Water Changes
Unbox, add water, power on. Compact body; the 4.5L float-sensor tank auto-alerts when low. Place in kitchen, living room, sideboard, or office.
The 1L removable Tritan jug lifts off for soup, porridge, coffee-machine refill, pets. Built-in UV auto-cycles; press child-lock for a 10-min manual sterilization. Clean the jug every 1-2 months.
Filters & Care
Filter Structure & Life
The Q5 uses three independent filters — replace whichever expires, not the whole set.
| Filter | Cycle | Function |
|---|---|---|
| No.1 Pre-Compound | ~6-8 months | Pre-carbon + PP cotton; sand, rust, suspended matter; adsorbs chlorine/color/odor |
| No.2 RO Membrane | ~2-3 years | RO membrane intercepts heavy metals, bacteria, organics |
| No.3 Post-Mineral | ~6-8 months | Premium mineral media + post carbon; releases mineral ions, improves taste |
Filter Replacement & Reset
When a filter's life shows a blinking empty icon with a "beep-beep", it needs replacing. Using No.1 as example:
1. While not producing water, twist from "Lock" to "Unlock" and pull out the old filter; within 30s the screen shows L1 (L2 for No.2, L3 for No.3) and beeps.
2. Insert the new filter, twist from "Unlock" to "Lock"; L1 clears with a beep and the empty bar fills — done.
① If the life indicator does not change, wait 1 min for chip recognition — do not twist the filter;② each chip resets only once — wait for the life prompt;③ after replacing, drain the jug 3 times as in the new-unit flush;④ use Bewinch original filters.
Video: Q5 Filter Reset Tutorial.
Daily Cleaning & Care
The 4.5L float-sensor tank is quick-release; clean every 1-2 weeks. Rinse the inside with clean water, wipe with a soft cloth; avoid hard brushes. Refit.
The 1L removable Tritan jug pulls out; clean every 1-2 months. Rinse with water, soft cloth inside. The built-in UV lamp auto-cycles for long-lasting inhibition.
After 3+ days idle, run one full self-clean: long-press "Custom/Clean" 5s; the unit flushes 30s and drains 100mL of 98°C hot water to prevent secondary path contamination.
Wipe with a soft dry cloth; avoid corrosive cleaners or hard cloths. Keep out of direct sun and damp.
Waste Water
Grade 2, purified rate 65%. Remaining raw-tank water flushes impurities off the filters. When prompted to change raw water, discard the waste and refill. Waste water is undrinkable but fine for cleaning or watering.
Cleaning & Descaling
Body: soft dry/damp cloth; no corrosive cleaners, steel wool; never immerse or spray the whole unit.
Raw tank (4.5L): remove every 1-2 weeks, rinse, soft cloth; deep-clean at least every 2 months.
Jug (1L): open/clean every 1-2 months; built-in UV auto-inhibits and stops when the jug is removed.
Drip tray: empty promptly.
Full self-clean: after 3+ days idle, long-press "Custom/Clean" 5s; flushes 30s and drains 100mL of 98°C hot.
The raw tank or heating path may scale over time — descale every 3-6 months:
1. Add warm water to the raw tank and dissolve food-grade citric descaler.
2. Run produce/dispense to circulate the solution through the path and heating tube.
3. Soak 15-30 min, then drain the concentrate.
4. Refill with clean water, produce/drain 3+ times to remove residue before use.
Use food-grade citric acid — no strong acids. If idle over 72h, first drain internal water, refill the raw tank, produce-full, drain, repeat 3 times.
FAQ
Water Quality
White foam is normal — it is fine bubbles that disappear on standing; safe to drink. Two causes:① Pressure: RO filtration dissolves some air under pressure; on dispensing, the pressure drops and air comes out as fine bubbles.② Temperature: hotter water holds more dissolved air; as hot water cools, air expands into fine bubbles.
Purified TDS can vary with colony count, water temp, and air pressure in non-laboratory conditions — normal. The Q5 uses RO + mineral media, so the output is mineral water that retains beneficial minerals; the TDS is not a pure-water value — do not compare it directly to pure water.
A slight odor on first use is normal — complete the full new-unit flush. During use, common causes:① filter expired;② jug long-unwashed;③ raw water quality worsened. Replace the filter, clean the jug, or change all raw water accordingly.
Operation
Long-press "Child Lock" 5s; on the beep, LOC shows at raw TDS and the unit cannot dispense/drain. Repeat to unlock (LOC clears). Child lock defaults off after shipping or power restart.
Press "Temp" for the temperature and "Volume" for the amount, then long-press "Custom/Clean" 5s to save. To use, press "Custom/Clean" then "Dispense/Stop" for one-tap fixed-volume output.
Place a heat-resistant container under the outlet, long-press "Custom/Clean" 5s. The unit cleans 30s and auto-drains 100mL of 98°C hot water, then resumes. Run after producing water (not while producing). Run once after 3+ days idle.
With the jug's lamp off, press the child-lock key to start manual UV; the jug lamp lights and auto-runs 10 min. Auto-cycle runs daily; manual mode boosts sterilization for guests or after long idle.
Filters
The Q5 has three filters: No.1 compound and No.3 post-mineral every 6-8 months; No.2 RO membrane every 2-3 years. Twist from "Lock" to "Unlock" to remove the old filter, insert the new one and twist back to "Lock"; power on and wait for auto recognition/reset, then drain/flush 2-3 times. Actual life depends on frequency, raw TDS, and volume — trust the on-screen prompt.
Unopened filters keep 5 years — store in a cool, dry place. A slightly higher TDS right after replacement is normal: new filter joints have food-grade grease and fresh activated carbon releases a little at first; thorough flushing restores it.
Use & Care
Use municipal tap water or purified water at 5-35°C. Never add hot, iced, drinks, or dirty water — it can damage filters and the unit. Change raw water regularly to avoid bacterial growth from long sitting.
The Q5 uses RO reverse osmosis; the booster pump runs while producing water (a normal sound) and stays quiet when not producing. The ~15s swirling flush after producing also makes a slight sound to protect filter life. This is a non-plumbed design — waste water stays in the raw tank; just drain it on water change. No external drain hose needed.
After-Sales & Service
The Q5 enjoys a 2-year nationwide warranty: in Year 1, a quality issue gets a brand-new replacement (replacement-only); in Year 2, non-human-caused damage is repaired free. For support, contact the store where you purchased. On first use you may book a free on-site setup via the Bewinch mini-program.
Sterilization & Eco
The Q5 comes with a 1.0S Enjoy removable sterilizing jug with a built-in UV lamp that inhibits bacteria in stored purified water, keeping every dispense fresh and safe.
The Q5 supports dual-mode: auto mode runs the UV lamp intermittently on a smart program; manual mode, with the lamp off, press the child-lock key to start UV and auto-run 10 min.
Long-press the 45/55°C temp key 5s; on the beep the screen goes off = eco. Press any key to restore full brightness.
The lamp uses smart detection and is not constantly on. With the purified tank full, power off, wait 30s, then power on — if the UV lamp lights, it is normal.
Filters & Use
The Q5 uses Spin ID auto-reset: twist from "Lock" to "Unlock" to remove the old filter, insert the new one and twist to "Lock"; the unit recognizes the chip and resets automatically. It is an RO unit that produces a small amount of concentrate (recirculated to the raw tank), drained on water change — no external drain hose needed.
The Q5 uses RO reverse osmosis, which needs a little water to flush the membrane surface; this recirculates to the raw tank as "concentrate." It is only slightly saltier than tap water — not dirty water. On each water change, discard the remaining raw-tank water and refill fresh. No external drain hose is required.
To avoid boiling over-pressure in a closed path, heating is controlled between 90°C and 100°C. The output is already deeply filtered to direct-drink standard, so it is safe to drink directly.
After airing out, fill the raw tank and produce water; drain ambient water 3-5 times, then flush with 45°C and 98°C once or twice each. The more you flush, the better the taste.
Every unit passes a 100% performance water-test before shipping, so a little residue is normal.
Drain the raw tank, refill with tap water, drain internal water then produce-full and drain — repeat 3 times before use.
Support
Scan the mini-program code on the unit's tank lid to enter the Bewinch mini-program and choose "Repair," or call the service hotline 400-828-0808, or contact the store where you purchased. Within one year of purchase, non-human damage qualifies for replacement-only.
Immediately cut power and stop the water supply, find the leak point, and contact official service. Never disassemble the unit yourself.
Troubleshooting
No water comes out
After pressing dispense, no water or slow flow.
Raw tank low; jug not seated; RO filter clogged or expired; child lock LOC not unlocked; temp/volume not selected.
① Check raw tank level — add water if low;② reseat the jug;③ check filter life and replace if expired;④ long-press child-lock 5s to clear LOC;⑤ confirm temp/volume selected. If still no water, contact the store where you purchased.
Water leak
Water pooling under or around the unit.
Raw tank/jug not installed correctly; tank seal aged or displaced; drip tray overflowing.
① Reinstall raw tank and jug, seating them firmly;② check tank seals;③ empty the drip tray promptly. If still leaking, cut power immediately and contact the store where you purchased — never disassemble yourself.
Not heating / water not reaching set temp
Set high temp but output is cool, or heating slows down.
Continuous heavy use let the heater recover; filter clogged; unit just powered on and not preheated.
① Wait 3-5 min after heavy use for the heater to recover;② check filter life and replace if expired;③ on a fresh start, dispense one cup to preheat the path. If still abnormal, contact the store where you purchased.
Odor / odd taste
Plastic, disinfectant, or other off-taste.
New unit not fully flushed; filter expired; jug long-unwashed; raw water quality worsened.
① New unit: complete the full flush;② check/replace expired filters;③ clean the jug and run manual UV;④ run one full self-clean;⑤ if raw water suddenly worsened, change all raw water.
Noise / abnormal sound
Noticeable noise while producing or heating.
Raw tank low causing dry run; unit not level; filter not seated; normal pump hum (a light buzz is normal).
① Check raw tank level — add water if low;② level the unit on a flat counter;③ open the lid and check filter seating;④ light pump/heating sounds are normal. If there is obvious rattle or vibration, contact the store where you purchased.
Screen off / touch unresponsive
Black screen or no touch response.
Screen-off eco mode; power not connected; child-lock LOC state; temporary system lag.
① Press any key to wake;② check the plug and socket power;③ if LOC shows, long-press child-lock 5s to unlock;④ long-press power 10s to restart. If the screen stays dark or touch misbehaves, contact the store where you purchased.
It still asks to replace the filter after I just did
After replacing, the screen still shows L1/L2/L3 or a blinking empty icon.
Filter not tightened; Spin ID chip recognition delay; non-original filter.
① Remove and re-tighten the new filter, from "Unlock" to "Lock";② wait 1 min for chip recognition — do not twist;③ if unchanged after 30s, pull out and reinsert a few times;④ use Bewinch original filters. If still prompting, contact the store where you purchased.
Raw TDS shows 999 and alarms
Raw TDS reads 999 and the buzzer sounds.
Local water is hard, or raw water wasn't changed in time, so raw TDS reached 999. Even after refilling, it stays 999 because no water has been produced yet.
① Change ALL raw water;② after refilling, dispense water so the unit starts producing — the raw sensor reads the new water and TDS drops;③ if you cannot change the hard water, long-press "Volume" 5s to silence (again to restore).
Fault light on after long idle
The fault indicator lights after long non-use.
Residual water in the path changed after long sitting — a normal reminder.
No need to worry — press "Dispense/Stop" to dispense, or run one full self-clean or drain, and it returns to normal. Before reusing after long idle, do a full drain-flush.
New filter packaging looks swollen
The outer plastic wrap of a new filter is inflated.
Filters are inflated and heat-sealed after production for air-tightness testing and faster flow — a better storage state.
Normal — no concern. Bewinch uses double-sealed packaging; as long as the seal is intact, it is safe to use.
Self-clean won't start
Long-pressing "Custom/Clean" 5s doesn't enter clean mode.
The unit cannot self-clean while producing water — wait until producing finishes.
Wait until producing is done (purified-volume light off), place a heat-resistant container under the outlet, then long-press "Custom/Clean" 5s to start self-clean.
E01 fault code
The screen shows E01 and the unit stops dispensing/producing.
Inlet water-temp sensor abnormal, usually from low ambient temperature (common in winter). When the sensor reads ~0°C, the unit triggers self-protection.
Move the unit to a warm room for 1-2 h; once the ambient sensor recovers, E01 clears. If it persists in a warm room, the sensor/control chip may be faulty and a technician must inspect the control components.
White foam / hazy water on first dispense
On first dispense, the cup shows white foam or a hazy look.
RO needs a booster pump to pressurize raw water; running the pump highly compresses air in the water into dense bubbles — the "haze."
A normal physical effect that does not affect water quality — safe to drink. Let it sit a moment; bubbles clear. After more flushing, internal air decreases and the effect weakens.
Slow flow / reduced volume
Dispensed volume drops noticeably.
Filter over life or clogged; raw tank empty.
① Add tap water;② check filter life and replace per the prompt.
No hot water
After selecting hot, only ambient water comes out.
① Hot temp not selected;② purified tank level too low;③ hot-water unlock not pressed.
① Select the hot temp first;② wait until the level is sufficient;③ press the hot-water unlock key.
Steam / splashing on high-temp hot water
High-temp dispensing hisses or splashes.
At high altitude the boiling point drops, and steam in the heating tube flows out with the water.
Hold the container close to the outlet; at altitude, watch for splashing.
Reset fails after filter change
The indicator keeps blinking after a filter change.
The Spin ID chip did not recognize the new filter.
Re-tighten the filter from "Unlock" to "Lock", wait 1 min for chip recognition, and avoid twisting it meanwhile. If it still blinks, reinsert a few times or contact the store where you purchased. Always use Bewinch original filters.
Filter life drains too fast
A filter wears out sooner than expected.
Power-on time, raw water quality, and total volume all contribute.
The life is a recommended cycle — plan around actual use; don't wait until it's fully clogged.
Leaks after a filter change
Water seeps under the unit after replacing a filter.
Filter not tightened or seated correctly.
Reopen the lid and twist the filter to the locked position, confirming it cannot be pulled out.
Outlet drips after closing
The outlet keeps dripping after dispensing stops.
New-unit path debris keeps the valve from sealing fully.
Drain a few more times to flush the path; if it still drips, contact the store where you purchased.
Buttons unresponsive with child lock on
All dispense keys do nothing and LOC shows.
Child lock is on.
Long-press the smart child-lock key 5s to turn off; on the beep, LOC clears and normal use resumes.
UV lamp not on
The jug's UV lamp doesn't light.
UV works in smart intermittent mode, not constantly on.
The purified tank must be full; power off, wait 30s, then power on — if the UV lamp lights, it is normal.
Tank turning green / algae
Green moss appears on the tank wall.
Green algae grow where light is strong.
Move the unit out of direct light and soak/clean the tank with citric acid.
Does the purified tank need cleaning?
The purified tank wall shows grime after long use.
The purified tank is semi-sealed food-grade plastic and needs periodic cleaning.
Long-press "Dispense/Stop" 5s to drain, wipe the wall with a lint-free cloth, then produce/drain 2-3 times. Recommended every 2-3 months.
Insects inside the unit
Insects found at the unit's base.
Insects enter through the base drainage holes.
Keep the area dry and ventilated and clean regularly; the internal path is fully sealed, so water quality is unaffected.
Water residue on a new unit's pump
A little water residue inside the new unit.
Residue from the pre-shipping performance water test.
Normal — flush before use.

Practical Tips & Self-Help
Slow production / no flow / intermittent flow — "air trapped"
① Power on and wait until it starts producing (a "putt-putt" sound); once done, open the lid and pull out a filter;② gently poke the hole at the filter's bottom with a chopstick to release air (if there's resistance, air is indeed trapped — water may spray out, so keep the filter bottom away from your face);③ repeat for each filter, then tighten them, wipe the table, and close the lid.
New unit / after water change, plastic odor remains despite repeated flushing
① Open the lid and purified-tank lid and air out 24 h;② if it persists, brew food-grade citric acid, pour into the tank to soak, then drain/flush 2-3 times;③ ensure the full new-unit flush (cold drain 3-5× + warm flush 1-2×).
Outlet drips a few drops after the cup is removed
New-unit dripping is usually residual carbon powder/debris in the path; drain a few more times (3-5×) to recover. If it persists after a while, contact the store where you purchased.
White floating particles in dispensed water
On a new unit or after a filter change, residual food-grade grease in the path can come out — normal. It clears after a few drains (5-10 cups) and is harmless.
Screen numbers jumping / touch intermittent
① Wipe water off the screen — capacitive touch misfires when wet;② check for unstable voltage, try a dedicated socket;③ if it still flickers, the touch film may be faulty — contact service to replace.
Pressing dispense but no water, display normal
① Check the lid is fully closed (an unlocked lid triggers safety lock);② power off 1 min, then on;③ confirm raw water and that the float rises;④ if none works, the diaphragm pump may be faulty — contact service.
Does the purified tank need regular cleaning?
Clean every 2-3 months:① remove the raw tank, open the lid and tank lid;② long-press "Dispense/Stop" 5s to drain (auto-stops);③ wipe the purified tank wall with a clean lint-free cloth;④ refill the raw tank and let it produce;⑤ drain again 2-3 times.
Hot dispense is intermittent with steam
Instant-heat units heat water to near 100°C in the tube, producing steam that makes the flow finer and slightly intermittent — normal. At high altitude the lower boiling point causes the same; try 85°C.
Insects at the unit's base
The base has drainage holes for safe draining; insects may enter when the environment has many. Fix:① keep the unit in a clean, ventilated, dry place and clean regularly;② place 1-2 non-toxic repellent sachets near each foot. The internal path is fully sealed, so water quality is unaffected.
Deep deodorizing after the new-unit flush still leaves a plastic smell
Wetted plastic parts are deodorized at the factory, but a sealed package can hold a slight plastic smell — normal. Usually airing the tank 12-24 h then flushing suffices. If it persists, try the "dish-soap method": dilute food-grade dish soap, circulate through the tank, then rinse with clean water 3-5 times. See the official video.
White scale/crystals on the raw tank wall
White powdery scale after long use is normal. To descale:① dissolve 5-10g food-grade citric acid in a cup of ~65°C water;② fill the raw tank with tap water and pour in the solution;③ soak 30-60 min;④ wipe the wall with a clean cloth until scale lifts;⑤ drain and rinse clean.
New filter outer packaging looks swollen
Normal. Filters are air-tested and inflated-sealed before shipping for better storage and flow; the wrap may swell. As long as the seal is intact, it is safe. Bewinch uses double-sealed packaging to protect filters in transit.
First-time production is very loud
Normal. A new unit's filters and pump hold lots of air; the pump compressing air makes noise. Repeatedly producing and draining soaks the path and the noise fades. If it still seems loud, check the counter is flat; a soft pad under the unit reduces resonance.
Black powder in the raw or purified tank on first flow
Normal. Activated-carbon filters are sintered from carbon powder and food-grade binder; fresh filters shed a little carbon on first flow — non-toxic. If raw-tank black powder appears, flush 3-5 times; if in the jug, rinse with tap water, wipe with a clean cloth, and drain/flush a few times.
Raw-tank water looks hazy with green/brown particles
Usually algae spores or pipe sediment from aging tap-water networks, more obvious in summer. The raw tank holds unfiltered tap water, so haziness does not affect output — after the RO membrane (0.0001µm), microbes, bacteria, and impurities are all removed, and the dispensed water is safe. Clean the raw tank regularly.
Water leak under or around the unit
① Close the inlet valve (if any), stop supply, and cut power;② self-check: did water spill during dispensing, or is the tank over the MAX line?③ open the lid and check all three filters seat correctly — remove and re-align/tighten 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? Why does the number change each time?
TDS (Total Dissolved Solids) is the total dissolved matter in water; a higher number means more minerals/impurities. The TDS is set by the raw water you add — not fixed. Pipes and filters hold old water that mixes with new, so the reading may be slightly higher than tap water. After changing raw water, dispense a cup so the probe reads the new water.
Why does the leftover raw-tank water get stronger / what is the waste water?
The RO membrane is 0.1nm precise; to keep impurities from clogging its pores, some water flushes the membrane surface and recirculates to the raw tank as "waste." It is only slightly saltier than tap water — not dirty. On each water change, discard the leftover and refill fresh; do not reuse waste water.
Fixed-volume dispensing is slightly off
A little water stays in the path, so fixed-volume dispensing has a small normal error — slightly more for hot water since flow speed changes with temperature. Use an accurate measuring cup; this is within normal tolerance.
A vertical line/mark on the outer shell
This is a natural knit line where plastic fuses in injection molding — an industry-wide phenomenon that does not affect use or looks. We keep improving the process to reduce it.
How is filter life calculated? Must I replace when it says so?
Filter life combines three factors:① power-on time (like a shelf life — decays over time even unused once wet);② raw TDS (worse water = faster use);③ total dispensed volume. The prompt is a recommended cycle, not a hard deadline — but don't wait until the filter is fully clogged, which can overload the pump or burst a hose.
