Bewinch G5 Xiaojimu R321

White foam is normal — it is fine bubbles that disappear when left to stand, and the water is safe to drink. Two causes: ① pressure change — during purification, pressure pushes water through the membrane and dissolves some air; when water dispenses, pressure drops and the dissolved air comes out as bubbles; ② temperature change — warmer water holds more air; as hot water cools, air comes out as fine bubbles.

The G3Pro uses RO reverse osmosis + natural mineral filter media, adding suitable natural media to simulate high-quality source water. It purifies first, then mineralizes, releasing beneficial minerals and improving taste. The output is sweet mineral water that needs no boiling and is safe to drink directly at room temperature.

Long-press the "60mL" volume icon 5 seconds and release after the beep to toggle child lock. When on, the child-lock icon lights and the raw-water TDS shows "LOC"; no dispensing can occur. It is off by default on a new unit or after a power reset.

The G-Radar night light only activates in standby (screen dimmed) when you place a cup under the spout. It will not trigger while the screen is on. This is by design, to wake the screen and lights automatically for nighttime water.

Poor local water quality or not changing the raw water in time can push raw TDS to 999; the unit beeps and prompts a water change. To turn off the alert tone, long-press the "85℃" key 5s (to toggle). However, high raw TDS accelerates filter consumption — change the raw water promptly when prompted.

The unit uses RO reverse osmosis; the booster pump runs normally during purification and makes some sound — this is normal. It goes quiet once purification stops. The ~15-second spiral convection flush after purification is also slightly audible and protects filter life. Place the unit on a flat surface or a soft mat to reduce resonance.

A swollen outer plastic wrap on a new filter is normal. After production, filters are inflated and sealed for air-tightness testing and faster filtration, which preserves them better. Bewinch uses double-layer sealing; as long as the seal is intact, it is safe to use.

If the filter indicator does not change within 30s after screwing in, pull it out and reinsert, repeating until it auto-resets. If it still won't reset, check that the bottom chip contacts are clean, or contact the store where you purchased. Each chip resets only its own filter once; double-check the filter model before replacing.

Stage 1 PP cotton and Stage 3 post-carbon are recommended every 6-8 months; the Stage 2 RO membrane every 2-3 years. Actual life depends on power-on time, local raw-water TDS and daily dispensed volume; the panel reminds you. Unopened filters have a 5-year shelf life — store in a cool, dry place.

The G3Pro's 26cm shallow-edge body with an easy-lift side tank greatly reduces countertop depth, suiting small homes and kitchens with limited space. The G-Radar 2.0 night light lights the screen automatically when you get water at night for peace of mind.

The G3Pro carries a 2-year nationwide warranty. Within the first year from purchase, performance faults are covered by a "replace-not-repair" service. For support, contact the store where you purchased, or reach the store through the Bewinch official mini-program.

The G3Pro is a no-install design — plug in and use, with no drain connection; waste water stays in the raw tank and is poured out on water changes. If you'd like guidance for first use, you may book a free on-site service via the Bewinch official mini-program or by contacting the store where you purchased.

The G3Pro uses sensor reset. Long-press the filter-reset key 5s; all three filter-life indicators flash fast to enter reset mode. Hold the anti-counterfeit sticker on the new filter near the NFC sensing area on the right side of the unit; a beep means reset is done. Each chip resets only once — reset only when the system prompts. After replacing, long-press "Dispense/Stop" 5s to drain 2-3 times before normal use.

① Open the top cover: press and slide it forward. ② Remove the old filter: grip the handle, turn the pointer from "locked" to "unlocked" and lift out. ③ Install the new filter: align the pointer with "unlocked" and insert into the matching slot, then turn to "locked" (confirm it cannot be lifted). After fitting, reset as above and drain 2-3 times.

Non-original filters may lack material hygiene assurance and have reduced filtration and sealing performance, which can cause abnormal water quality, safety risks and shorter unit life. Buy replacements from official authorized channels when a filter alarms; filters from unofficial channels cannot be reset and the unit will not work.

Place a heat-resistant container under the spout, long-press the "Sterilize/Clean" or "Custom/Clean" key 5s to start self-cleaning. The unit cleans for ~30s, automatically dispensing ~100mL of 98℃ hot water, then stops on its own; press the key again during the cycle to cancel. Run a clean cycle once if the unit has been unused for over 3 days.

From the heat-capacity formula Q=cmΔt, a higher target temperature means a larger temperature difference and more energy needed. The unit's max power is limited, so to reach the set temperature quickly it reduces the water flow — the hotter, the smaller the flow. This follows energy conservation and is normal.

To avoid re-contaminating purified water, the unit uses a sealed structure. Heating water to 100℃ boils it into steam, raising pressure inside the heating tube. So countertop purifiers usually heat above 90℃ but below 100℃. The unit uses deep RO filtration; the output meets national direct-drinking standards and is safe to drink even unboiled.

Clean every 2-3 months. ① Remove the raw tank and open the unit top cover and purified-tank lid; ② long-press "Dispense/Stop" 5s to drain, then it stops automatically; ③ wipe the purified-tank interior with a clean lint-free cloth; ④ refill the raw tank and wait for auto purification; ⑤ drain 2-3 more times.

First pour out the remaining raw-tank water and refill with municipal tap water. Power on and drain all internal water; wait until the purified tank fills, then empty it; repeat 3 times before normal use.

Waste water is not sewage — it is concentrated water the RO uses to flush impurities off the membrane, to maintain filter life. Raw water and waste share one tank: the raw inlet is on top, the waste outlet on the bottom, so they naturally separate by density; combined with filter flush technology, waste water is not re-filtered. Purified water from four-stage filtration is stored in the purified tank to keep drinking water safe; when raw-water concentration reaches a threshold, the unit prompts a water change.

Phenomenon: Pressing dispense gives no water or very slow flow.
Possible causes: Raw tank empty, purified tank not full, filter clogged, child lock on, or wrong temperature/volume setting.
Solution: ① Check raw-tank level and refill; ② wait for purification (~10 min); ③ check filter life and replace if due; ④ unlock child lock; ⑤ confirm settings. If still no water, contact the store where you purchased.

Phenomenon: Puddles under or around the unit.
Possible causes: Raw/purified tank not seated, tank seal aged/misplaced, drip tray overflowing.
Solution: ① Reinstall tanks until they click; ② check seals; ③ empty the drip tray promptly. If it still leaks, unplug immediately and contact the store where you purchased — do not disassemble.

Phenomenon: Set high but output is cool, or heating slows.
Possible causes: High-altitude low boiling point (above 1,800m), heating chamber not recovered after long dispensing, clogged filter, unit just powered on.
Solution: ① At altitude, set temperature may not be reached — normal; ② wait 3-5 min after long dispensing; ③ check/replace filters; ④ dispense a cup first to warm the lines. If still abnormal, contact the store where you purchased.

Phenomenon: Plastic, disinfectant or other off-taste.
Possible causes: New unit under-flushed, filter due, tanks uncleaned, raw water quality worsened.
Solution: ① Complete full flushing (cold drain ×3, 45℃ ×1-2, 98℃ ×1-2); ② check/replace filters; ③ clean raw and purified tanks; ④ if raw water suddenly worsened, replace all raw water.

Phenomenon: Noticeable noise during purification or heating.
Possible causes: Raw tank empty causing dry run, unit not level, filter not seated, normal pump hum.
Solution: ① Check raw-tank level; ② level the unit on a flat surface; ③ open the cover and reseat filters; ④ mild pump/heating hum is normal. If there is clear rattle or vibration, contact the store where you purchased.

Phenomenon: Black screen or no touch response.
Possible causes: No power, child lock on, screen-off eco mode.
Solution: ① Check plug and outlet; ② if locked, long-press 60mL 5s to unlock; ③ tap any key to wake. If the screen stays dark or touch is abnormal, contact the store where you purchased.

Phenomenon: Raw TDS reads 999, buzzer sounds, low-water light on.
Possible causes: Poor local water or stale raw water; even after changing water, it still reads 999 because no purification has run.
Solution: ① Replace all raw water; ② after refilling, dispense so the unit starts purifying — the probe detects new water and TDS drops; ③ to silence the alarm, long-press "85℃" 5s (toggle).

Phenomenon: After long disuse, the screen fault indicator lights.
Possible causes: Normal reminder from residual water changing in the lines after sitting.
Solution: No need to worry. Just press "Dispense/Stop" to dispense, or remove the pitcher, empty and reseat it. For reuse after long idle, run a full flush first.

Phenomenon: White powery crystals form on the raw-tank wall over time.
Possible causes: Regional water-hardness differences cause limescale.
Solution: ① Mix 5-10g food-grade citric acid in a cup of ~65℃ hot water until dissolved; ② fill the raw tank with tap water and add the solution; ③ soak 30-60 min and wipe with a clean cloth until scale lifts; ④ pour out and rinse thoroughly.

Phenomenon: Screen shows E01; unit stops dispensing and purifying.
Possible causes: Inlet water-temperature sensor abnormal, usually from very low ambient temperature (common in winter); the sensor near 0℃ triggers self-protection.
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 environment, the sensor or control board may be faulty — arrange service by calling 400-828-0808.

Phenomenon: Long purification or noticeably slower.
Possible causes: Raw tank empty, filter clogged/due, high raw TDS, low ambient temperature, pump fault.
Solution: ① Refill to max line; ② check/replace filters; ③ replace all raw water and repurify; ④ keep ambient 5℃-35℃. If still not purifying, contact the store where you purchased.

Phenomenon: Leak at the purified tank / pitcher connection.
Possible causes: Pitcher not seated, seal aged/misplaced.
Solution: Reinstall the pitcher until it clicks and check the seal. If it still leaks, contact the store where you purchased.

Phenomenon: Drip tray overflows or gets dirty.
Possible causes: Spilled water and residual line water collect in the tray; needs periodic cleaning.
Solution: Remove the tray as shown, empty and wash, then replace. Check and clean regularly.

Phenomenon: Taking hot water pops E02 and stops flow.
Possible causes: Outlet temperature sensor open circuit (reads 100℃), or outlet NTC cracked and letting in moisture.
Solution: Restart and see if it recovers; if it recurs, the outlet NTC is likely cracked/moist — contact service to replace or repair the sensor by calling 400-828-0808.

Phenomenon: Screen shows E03 (outlet sensor short, reads 0℃) or E04 (outlet sensor open, reads 120℃).
Possible causes: Outlet temperature sensor abnormal.
Solution: It clears automatically once the fault is fixed; if E03/E04 persists, contact service to check the outlet temperature sensor by calling 400-828-0808.

Phenomenon: Screen shows E07, drain abnormal prompt.
Possible causes: Continuous drain for 10 minutes still not complete; usually a blocked drain line.
Solution: Power off to clear; check the drain line for blockage. If it recurs, contact service by calling 400-828-0808.

Phenomenon: Screen shows E11.
Possible causes: Heating fault — after 20s it still hasn't reached half the target temperature, usually from too-cold raw water.
Solution: Power off to clear; confirm using 5℃-35℃ municipal tap water. If it recurs, contact service to check the heating system by calling 400-828-0808.

Phenomenon: New unit shows raw 04, pure 03 and does not purify.
Possible causes: Factory default — before a new unit passes water, all show raw 04 / pure 03 by default; not a fault, as no water has really passed through.
Solution: ① If the water-change light shows 0403: check the raw-tank float wasn't left out; reseat the tank a few times; ② If the light is off but still shows 0403: complete the new-unit flush and purify normally; the display updates. If it still won't purify, the booster pump or waste-water solenoid may be faulty — contact service.

Phenomenon: Raw tank has water but the unit prompts a change or shows empty.
Possible causes: ① Tank float not fitted or weak magnetism; ② poor tank-to-body contact; ③ TDS 999 alarm.
Solution: ① Fill to max and check the float seats and floats in full water; ② reseat the tank firmly; ③ on TDS 999, after refilling, dispense so purification runs — the probe detects new water and TDS drops.

Phenomenon: Hot water flows thin and fluctuates, with a little steam.
Possible causes: Instant-heat near-boiling heats water to ~100℃ in the tube, forming steam; for accurate temperature the flow is thinner than ambient — normal.
Solution: A normal physical effect; no action needed. At altitude it may be more noticeable; hold the cup close to the spout.

Phenomenon: Hot water spits or splashes when dispensing.
Possible causes: At altitude the boiling point drops, steam volume in the tube rises and exits with the flow; even ambient-set units may briefly do this with very cold raw water.
Solution: Hold the container close to the spout. At altitude, watch for splashing on first use; some areas may not deliver the highest-temperature level reliably.

Phenomenon: Seepage from the raw-tank bottom.
Possible causes: Bottom inlet/outlet valve loose, not fitted, or scaled.
Solution: Refit the bottom valve and tighten; fill the tank, wipe the bottom and test it alone. If still leaking, gently rotate/press the bottom inlet/outlet valve until it stops; if needed, contact the store where you purchased for guidance.

Phenomenon: New unit's spout keeps dripping.
Possible causes: Debris in the new-unit lines preventing the valve from sealing.
Solution: Drain a few times to flush out debris. If it still drips after several drains, contact service.

Phenomenon: Leaking and noise after replacing or fitting a filter.
Possible causes: Filter not tightened or seated; refitting an old filter may seal poorly.
Solution: Power off, open the cover, remove each filter and reseat it firmly. Use new filters — an old filter may show restored bars but loses purification efficiency and speed.

Phenomenon: Screen normal, but the unit beeps nonstop during dispensing.
Possible causes: Heating element or diaphragm pump issue.
Solution: Contact service to inspect the heating element or diaphragm pump by calling 400-828-0808.

Phenomenon: Display abnormal, e.g. temperature icon flashing, screen blacking then recovering.
Possible causes: Display control module abnormal.
Solution: Restart and observe; if it recurs or stays black, contact service to replace the display module by calling 400-828-0808.

Phenomenon: Purified-volume light turns red, overflow prompt.
Possible causes: Purified tank/pitcher not seated or poor contact, triggering the overflow sensor.
Solution: Reseat the purified tank/pitcher firmly, then drain (dispense) to clear the overflow display.

Phenomenon: Raw TDS reads lower than purified TDS.
Possible causes: ① You poured purified water into the raw tank, so raw TDS is naturally low; ② new unit under-flushed, internal lines not clean; ③ when raw water is very pure, the RO makes little waste and flushes the purified probe less, so the purified value may read slightly higher.
Solution: ① Use municipal tap water as raw water; ② complete a full flush; ③ after a week of higher-TDS tap water, raw will read above purified — normal, no impact.

Phenomenon: After airing and repeated boiling, a new unit still smells strong.
Possible causes: New filters and lines may carry a slight odor.
Solution: Open the top cover and purified tank, leave open 24 hours. If it persists, identify the source (raw or purified tank) and soak with brewed citric acid in the tank.

Phenomenon: Green moss-like growth on raw or purified tank walls.
Possible causes: Airborne algae spores enter the water and grow in bright places.
Solution: Move the unit away from light, clean tanks promptly, and soak/wipe tank walls with citric-acid solution.

Phenomenon: After moving the raw or purified tank mid-purification, air lock and leak appear.
Possible causes: Moving a tank while purifying lets air into the water lines.
Solution: Never move raw/purified tanks while purifying; wait until purification finishes or power off / until a water-change prompt before moving tanks.

Phenomenon: After replacing, resetting by NFC gives no beep near the sensing area; the light still flashes.
Possible causes: ① Not within the 30s reset window; ② anti-counterfeit sticker not near the right-side NFC area; ③ filter chip not sensed or not screwed in.
Solution: Long-press the filter-reset key 5s until all three indicators flash, then hold the new filter's sticker near the right-side NFC area; a beep means done. If no response, pull and reinsert and retry. Each chip resets only once — reset only when prompted.

Phenomenon: Pressing self-clean gives no response or won't enter mode.
Possible causes: ① No heat-resistant container under the spout; ② wrong press (must long-press, not tap); ③ unit in child lock or purifying.
Solution: Place a heat-resistant container under the spout and long-press "Sterilize/Clean" or "Custom/Clean" 5s; the unit dispenses ~100mL of 98℃ hot water and ends; press again to cancel. Run a clean cycle if unused over 3 days.

Phenomenon: Insects found inside or at the base.
Possible causes: The base has drainage guide holes (to prevent internal leaks), so insects can enter when the environment has many.
Solution: ① Place the unit in a clean, ventilated, dry spot and clean it regularly; ② put 1-2 non-toxic repellent sachets around the four feet, kept flat and stable. The internal water path is fully sealed, so water quality is unaffected.
