Core Technology Details

Hyper2.0 High-Flow Bionic-Filtration RO Membrane

Hyper-nano bionic filtration is a high-flow membrane designed by Bewinch specifically for under-sink purifiers; the H7 is the first model to carry the Hyper2.0 filter. Its service life is over 65% longer than APQ3.0 and its filtration rate is 10x faster, with stronger hydrophilicity and greater purification efficiency. Heavy-metal removal ≥99.9%, harmful chloride removal ≥99.9%, and performance holds up over long-term use.

Three-Filter Independent Structure

Most under-sink purifiers use a two-filter design (PCB + RO) or a single composite filter. The H7 uses a rare three-filter structure: pre-composite filter + Hyper2.0 RO reverse-osmosis membrane + rear taste filter. The added independent mineralization taste filter uses imported high-iodine-value natural coconut-shell activated carbon (1300 mg/g) and natural ore. It further blocks chlorides (trihalomethanes, dichloroethylene, and other disinfection by-products) that the RO membrane cannot filter, and greatly improves taste — water tastes as sweet and clear as spring water.

pH7.6 Mineralized Alkaline, Low-Sodium Light-Mineral Spring Water

Pure water from most under-sink purifiers contains no minerals and is slightly acidic (pH 6.3-7), unsuitable for brewing and long-term drinking. The H7 delivers pH7.6 mineralized alkaline water with 8 beneficial minerals — calcium, magnesium, sodium, potassium, zinc, strontium, selenium, and metasilicic acid — great for wellness and flower/fruit teas for a fuller brew. Mineral ratios follow WHO infant drinking-water guidelines: sodium ≤20 mg/L, TDS ≤100 mg/L, 0 BPA — low sodium and light minerals for healthy baby growth.

AVP Micro-Bubble Oxygenation

Modeled on how natural spring water gains oxygen as it flows through mountain streams, the unit has a built-in aeration structure that increases contact area between water and air, raising dissolved oxygen for fresher, more lively water on tap.

Servo Vacuum Heat-Pump System

It combines instant heating with a double-layer vacuum insulated tank for faster heating than traditional instant tech — a cup of hot water in just 3 seconds. 45°C warm-water volume rises 7x and 98°C boiling volume rises 5x. Internal 3/8-inch large pipes deliver up to 4 L/min ambient flow, so neither hot nor cold flow is overstated. The insulated tank holds water at a steady 95°C and reheats automatically below 85°C.

AI Integrated Alloy Smart-Display Faucet

A high-sensitivity touch panel usable with wet hands, controlled by a knob — easy for both the elderly and children. It smart-displays water quality, filter life, and temperature/volume, with a 5-color ring showing dispensing status: blue = ambient, red = hot, green = draining, orange = self-cleaning/fault, purple = UV sterilization. Nighttime dispensing is clear at a glance.

Full-Area Self-Cleaning & Sterilization System

With deep self-cleaning AI and a sterilization system, the full water path self-cleans at up to 99.99% sterilization for 24-hour antibacterial protection. UV sterilizes for 10 minutes every hour, ensuring every drop of water is pure.

Scenario Applications

Fresh Kitchen Water, One Unit, Many Uses

Kitchen cooking: rice, soup, fruit rinsing, boiling — high-flow ambient and hot water on tap; better water, better-tasting food.

Tea & coffee: pH7.6 alkaline water brews a fuller tea; 45°C / 85°C / 98°C three hot levels one-touch.

Mother & baby direct drinking: low-sodium light minerals (sodium ≤20 mg/L); 45°C warm water for easy formula — drink directly without boiling.

Living room / office: the under-sink unit is hidden and space-saving, leaving only the smart faucet on the counter — clean and tidy.

Under-Sink Installation Steps

The H7 is an under-sink unit requiring inlet, drain, and power connections plus a faucet on the countertop. Below is the standard flow performed by a professional installer. Self-installation requires some skill; improper installation may cause leaks or failure to purify, and you bear responsibility.

Step 1: Confirm Under-Sink Space

 ① Reserve a spot under the cabinet: depth ≥55cm, width ≥25cm, height ≥50cm, so the unit sits steadily;

 ② A municipal cold-water inlet within 1.2m and a grounded 10A 3-prong outlet within 1.5m;

 ③ A sink/drain nearby to connect the drain tube;

 ④ A 29-31mm faucet hole on the countertop (first installation includes free on-site drilling).

Step 2: Inlet Connection (Tee Valve)

 ① Close the home main water valve;

 ② Fit a tee ball valve on the under-sink cold-water inlet — one side to the original tap, one side to the unit's 3/8" PE inlet tube;

 ③ Inlet pressure must exceed 0.15 MPa; add a booster if needed;

 ④ Push the PE tube into the fitting and secure with a clip so it cannot pull out.

Step 3: Drain Connection

 ① Run the 1/4" drain tube to the under-sink drain/sink outlet;

 ② Secure the tube with the drain clamp to prevent blow-off under flow;

 ③ Buy a sink drain tee separately if needed; keep the drain tube unobstructed and un-kinked.

Step 4: Power Connection

 ① Power is 220V~50Hz, 10A 3-prong grounded outlet recommended;

 ② Outlet within 1.5m of the unit; keep the cord away from pinch points and heat sources;

 ③ Do not plug in during installation — power on only after tubing is connected and leak-checked.

Step 5: Faucet Installation

 ① Pass the AI smart faucet through the 29-31mm countertop hole and secure it with a nut underneath;

 ② Connect the purified-water tube and signal wire between faucet and unit;

 ③ Confirm the faucet is firm and the water tubes connect to the right ports;

 ④ Slowly open the tee ball valve and main valve, then check all joints for leaks.

After installation, run water and leak-check first — power on only when no leaks are found. If a leak appears, immediately close the tee valve and cut power.

New-Unit Flushing Guide

After installation, follow these flushing steps to activate filters and clean the water path.

Step 1: Open the Tee Valve

After installation, open the tee ball valve and point the faucet toward the sink.

Step 2: Plug in for Auto-Flush

Plug in; the unit auto-flushes for about 10 minutes and the faucet shows the "Flushing" icon. No dispensing is allowed during flushing.

Step 3: Hot-Water Drain

On power-on, the tank heating is on by default; the tank fills in about 5 minutes. Touch the screen, select 98°C, press the knob — the dispensing light turns red — and drain hot water 3-4 times (each drain ends when the faucet stops).

If a leak appears, close the valve and cut power immediately. During hot flushing, keep hands and face away from the faucet's steam vent and spout to avoid burns.

Daily Use

Faucet Operation

Dispense / Temperature Knob

1. Turn the "Dispense/Temperature" knob, or touch the "45°C" "85°C" "98°C" icons on the faucet screen to set temperature;

2. Touch the "Volume" key to cycle volume: ambient 3 levels (0.5L/1L/1.5L), hot 4 levels (0.2L/0.3L/0.5L/1L); continuous flow if no volume is selected;

3. Press the "Dispense/Temperature" knob to start/stop water.

When the tank volume icon flashes, the insulated tank is low and hot levels are unavailable. Small hot preset flow is normal; in Eco mode the hot flow is even smaller.

Light-Ring Colors

Blue: dispensing ambient  Red: dispensing hot  Green: drain mode

Orange: self-cleaning / first-power drain / fault  Purple: UV sterilization active

Two Hot-Water Modes

Tank Heating Mode (Default)

On by default. Hot water comes from the unit's double-layer vacuum tank (steady 95°C) for a large hot flow, suited to cooking and heavy drinking. When the tank drops below 85°C it reheats automatically; an abrupt boiling sound during this is normal.

Eco Mode

Long-press the unit panel "ECO" key for 5 seconds to toggle. In Eco mode, the tank stops filling and recirculating; hot water is instant-heated — smaller volume but lower energy use. Enable Eco when you don't need large hot flow.

Before enabling Eco, long-press the self-clean key to drain and flush the tank, so the next hot-water temperature is not affected.

Smart Features

Smart Child Lock

Long-press the "Dispense/Temperature" knob for 5 seconds; after a beep, the child lock toggles on/off. When the lock icon is on, other dispensing keys are disabled to prevent accidental scalding by children. It is off by default at first power-on and after a power cycle.

Auto-Flush & Manual Self-Clean

Auto-flush: 30s flush after power-on; 15s flush after 30 min cumulative purification; 30s flush after 24h standby. Flushing carries away membrane contaminants and extends filter life; the unit suddenly running or vibrating during flush is normal.

Manual self-clean: If unused for over 3 days, long-press the unit self-clean key for 5s to run a full water-path self-clean (filters + tank), ending in about 10 minutes. Point the faucet at the sink during flushing — hot water comes out, never touch the flow.

Tank Drain

Long-press the faucet "Volume" key for 5 seconds; after a beep it enters tank-drain mode with a green ring. Press the knob to drain; it auto-resumes when empty. Before long idle or disassembly, drain residual water to avoid odors. Hot water is present during draining — take care.

Low Inlet-Water Alert

When the inlet valve is closed or inlet pressure is too low, the faucet shows a "tap" icon, meaning the supply is low and the unit cannot run normally. Restore the water source or adjust pressure before use.

Benefits of the Three-Filter Structure

Why Three Filters?

① Independent life, independent replacement: each filter works alone; replacing one doesn't affect the others, avoiding the "one-size-fits-all" issue of composite filters (either too late or too early).

② Taste optimization, sweeter water: the independent mineralization taste filter greatly improves drinking taste — better tea, coffee, and rice.

③ Graded treatment, finer filtration: the No.3 filter further blocks chlorides the No.2 RO membrane cannot, lightening the load on the main membrane and handling harder water.

Temperature Levels & Use Cases

The H7 supports 4 temperature levels and multiple volume presets via the AI smart faucet:

TemperatureTypical Use
AmbientDirect drinking, soup/rice, fruit rinsing, heavy cooking; up to ~4 L/min
45°CFormula, warm direct drinking; gentle on the palate, safe for babies
85°CCoffee, black tea, oolong
98°CBoiling direct drinking, noodles, tea, high-temp cooking

Hot presets: 0.2L/0.3L/0.5L/1L (small preset flow is normal); ambient presets: 0.5L/1L/1.5L, continuous if no volume selected. For large hot flow, turn off Eco mode (tank heating mode).

Filters & Care

Filter Structure & Life

The H7 uses three independent disposable filters — no technician needed; replace them yourself. Filter life decays blue → orange → red.

StageReplacementFunction
1: M20 Pre-Composite18-24 monthsBlocks rust, sediment, colloids, suspended matter; adsorbs chlorine, color/odor, pesticide residue
2: Hyper2.0 RO5-6 yearsNano-bionic filtration; bacteria, heavy metals, scale; life over 65% longer than APQ3.0
3: Q20-OH Alkaline Taste18-24 monthsImported coconut carbon + natural mineral ore; blocks chlorides, improves taste, releases minerals

Life indicator: 100%-35% blue, 35%-5% orange, under 5% red. On red, the faucet "Filter" text flashes and beeps (10s after each operation). Actual life depends on water quality, usage, and power-on time; replace within 15 days of expiry to avoid a clogged filter overloading the booster pump.

Filter Replacement & Reset

Replacement Steps
  1. When any filter reaches end of life, its front-panel light turns red and the faucet "Filter" text flashes;
  2. You must first close the inlet tee ball valve and open the faucet to run the unit for 1 minute, relieving pressure at the filter ports;
  3. Pull the filter ring; after the filter pops out, pull it straight out, then remove the decorative cover per the arrow on top;
  4. Keep the cover ring closed, screw it onto the new filter, align it with the hole and push in — a "click" means it is seated;
  5. Long-press the "Filter Reset" key for 5s; the unit light comes on and the No.1 light flashes into reset mode; press reset once to select the target filter;
  6. With the target filter selected, long-press reset for 5s; after a beep the light stops flashing and turns blue — reset done;
  7. Open the inlet valve, long-press the unit self-clean key to drain and flush; after ~2min30s return to normal use.

Do not force out a filter while the unit is running. When removing/fitting a filter cover, always close the ring before turning to the unlock/lock mark.

Regular Maintenance

Self-Cleaning & Sterilization

The H7 has a full-area self-cleaning system: UV works for 10 minutes every hour for 24-hour antibacterial protection. If unused for over 3 days, run a self-clean before dispensing.

After a Water Outage

During a tap-water outage, pipes may collect rust and sediment. To avoid clogging the unit's pipes and electrics, cut power during the outage. When water is restored, first open a normal tap to drain muddy water, then power on and use the unit.

Unit Care

Keep the under-sink installation dry and ventilated; avoid damp, direct sun, cold, and uneven surfaces. Wipe the exterior with a soft dry cloth; do not disassemble the unit yourself. If you find leaking from the bottom or external pipes, cut power, close the valve, and call the service hotline promptly.

Cleaning & Descaling

Daily Cleaning

 ①Faucet: wipe the smart faucet and light ring with a soft damp cloth; keep the touch panel dry and clean;

 ②Unit: wipe the under-sink unit with a dry cloth; keep the area dry and ventilated; don't let the unit sit in water for long;

 ③Pipe joints: periodically check joints for leaks or scale;

 ④UV self-clean: the built-in system runs UV 10 min every hour, no manual action; after 3+ days idle, self-clean before dispensing.

Pipe & Tank Descaling / Drain

 ①Tank drain: long-press the faucet "Volume" key 5s to enter drain mode (green ring), press the knob to empty; drain before long idle or disassembly;

 ②Periodic self-clean: long-press the unit self-clean key 5s for a ~10-min full water-path clean; point the faucet at the sink and watch for hot water;

 ③Descaler: if local water is hard and heating slows, contact support to use the official descaler on the heater and tank;

Do not disassemble the unit or use strong acid/alkali descalers. Hot water is present during draining and self-clean — take care.

If unsure about descaling or maintenance, contact the store where you purchased for guidance.

FAQ

Water Quality

What water does the H7 produce? Is it drinkable directly?
Water QualityAlkalineDirect Drinking

The H7 delivers pH7.6 mineralized alkaline water with 8 beneficial minerals — calcium, magnesium, potassium, sodium, zinc, strontium, selenium, and metasilicic acid — low in sodium and light in minerals (sodium ≤20 mg/L, TDS ≤100 mg/L). After Hyper2.0 RO reverse osmosis and 3-filter precision filtration, bacteria and heavy-metal removal is ≥99.9%. No boiling needed — drink ambient directly; also ideal for baby formula and tea.

Why is my water alkaline instead of pure water?
Water QualityMineralspH

Pure water from ordinary under-sink purifiers contains no minerals and is slightly acidic (pH 6.3-7). The H7 adds a No.3 Q20-OH alkaline taste filter after the RO membrane, which releases balanced minerals from natural ore — purified first, then mineralized — producing pH7.6 spring-taste alkaline water that brews a fuller tea. This is a design feature, not a fault.

White foam / bubbles in the water?
Water QualityBubblesAVP

The white foam is tiny bubbles that dissipate when left standing — safe to drink. On one hand, RO purification pressurizes air into the water, which releases as bubbles when pressure drops at the spout. On the other, the H7 has a built-in AVP micro-bubble oxygenation structure that actively raises dissolved oxygen for fresher water, making the bubbles more noticeable.

Operation

Why is hot-water flow weaker than ambient?
OperationHot WaterFlow

Small hot-preset flow is normal. The hot presets (0.2/0.3/0.5/1L) are designed for precise small-volume dispensing. For large hot flow, long-press the unit "ECO" key for 5s to turn off Eco mode and use tank heating mode — hot water then comes from the double-layer vacuum tank with a larger flow. Ambient flow reaches up to 4 L/min.

What do the faucet light-ring colors mean?
OperationLight RingFaucet

Blue = ambient dispensing; red = hot dispensing; green = drain mode; orange = self-cleaning / first-power drain / fault alert; purple = UV sterilization active (works 10 minutes every hour).

Why does the unit suddenly start purifying / flushing?
UseAuto-FlushNoise

It auto-flushes 30s after power-on, 15s after 30 min cumulative purification, and 30s after 24h standby; the tank also reheats automatically below 85°C. These routines carry away membrane contaminants and maintain filter life and water temperature. The unit suddenly running or vibrating slightly during flush is normal.

How do I toggle the child lock?
OperationChild LockSafety

Long-press the faucet "Dispense/Temperature" knob for 5 seconds; after a beep, the child lock toggles. When on, the screen shows the lock icon and other dispensing keys are disabled. It is off by default at first power-on and after a power cycle.

The unit is 455mm (L) × 190mm (W) × 425mm (H); install clearance recommended depth ≥55cm, width ≥25cm, height ≥50cm. Countertop faucet hole 29-31mm. Also need a municipal water source within 1.2m and a 10A 3-prong outlet within 1.5m.

How often to replace filters? Is daily drinking expensive?
FilterLifeCost

The No.1 M20 pre-composite and No.3 Q20-OH alkaline taste filters should be replaced every 18-24 months; the No.2 Hyper2.0 RO filter lasts 5-6 years. The three filters are staggered, so a bundle set covers 5-6 years of changes. Actual life follows the faucet indicator.

It prompts to replace the filter, but I just did / reset won't work?
FilterReset

After replacing, reset manually: long-press the unit filter-reset key for 5s to enter reset mode (No.1 light flashes), press once to select the target filter, then long-press 5s — after a beep the light turns blue and reset is done. Always close the valve and relieve pressure before removing a filter, and close the cover ring before tightening. If it still won't reset, contact the store where you purchased.

After-Sales & Service

How long is the H7 warranty?
After-SalesWarrantyExtension

3-year base warranty from purchase; after product registration you get an extra 2-year extension, for up to 5 years total. The warranty starts on successful order payment and does not cover consumables such as filters. For support, contact the store where you purchased.

Can I install it myself?
InstallSelf-Install

The H7 includes free first on-site installation; we recommend a professional installer for a neat, reliable result. Self-installation requires some skill; improper installation may damage the unit or prevent purification, and you bear responsibility. You can follow the self-installation video.

Installation & Environment

What are the basic under-sink installation requirements?
InstallUnder-SinkWater Pressure

 ① Water: municipal tap water, 5-35°C, inlet pressure >0.15 MPa (add a booster if low);  ② Power: 10A 3-prong grounded outlet within 1.5m;  ③ Environment: 4-40°C, water source within 1.2m;  ④ Drain: clamp the drain tube to prevent blow-off;  ⑤ Clearance: depth ≥55cm, width ≥25cm, height ≥50cm;  ⑥ Countertop faucet hole 29-31mm (first drilling free on site).

How do I book installation and repair?
InstallBookingSupport

 ① Scan the mini-program QR code on the unit/manual, enter the Bewinch mini-program, choose "Installation/Repair" and submit;  ② contact the store where you purchased. First installation is free; non-first installs carry a service fee, and site modifications are extra. Have the machine SN code ready when reporting a repair. For repair and on-site service, call official hotline 400-828-0808.

How does the H7 drain waste water?
Waste WaterDrainUnder-Sink

The under-sink H7 drains waste water directly into the drain pipe; secure the drain tube with a clamp to prevent blow-off under pressure. The waste water is concentrate from membrane flushing — better than tap water but not drinkable.

Operation & Modes

How do I switch between Eco mode and tank heating mode?
EcoECOTank

Long-press the unit "ECO" key for 5s to toggle between the two. In Eco mode, hot water is instant-heated with a smaller preset flow; with Eco off it switches to tank heating mode, where hot water comes from the double-layer vacuum tank with a larger flow. Ambient water reaches up to 4 L/min.

How do I use the self-clean function?
Self-CleanClean98°C

Place a heat-resistant container under the spout. When triggered, the unit automatically drains about 100mL of 98°C hot water to flush the pipes, stopping itself after about 30 seconds. If unused for over 3 days, run a self-clean.

Why doesn't the UV lamp light up?
UVSterilizeLight Ring

The H7's purple light ring means UV sterilization is running. It is a smart cycle — 10 minutes every hour — not a constant-on light, so this is normal by design.

Why does the unit auto-flush / suddenly start?
FlushAutoPurify

It auto-flushes 30s after power-on, 15s after 30 min cumulative purification, and 30s after 24h standby; the tank reheats automatically below 85°C. These routines maintain the RO membrane and water temperature; the unit running on its own or vibrating slightly is normal.

Filters & After-Sales

How do I reset H7 filters?
FilterResetH7

After replacing, reset manually: long-press the unit filter-reset key 5s to enter reset mode (No.1 light flashes), press once to select the target filter, then long-press 5s — after a beep the light turns blue and reset is done. Always close the valve and relieve pressure before removing a filter.

How long does the Hyper2.0 RO filter last?
ROFilterLife

The No.2 Hyper2.0 RO filter lasts 5-6 years; the No.1 pre-composite and No.3 alkaline taste filters should be replaced every 18-24 months. The three filters are staggered; follow the faucet indicator.

What is the H7 after-sales warranty policy?
WarrantyAfter-SalesExtension

3-year base warranty from purchase; after product registration you get an extra 2-year extension, up to 5 years total. The warranty does not cover consumables such as filters. For support, contact the store where you purchased.

What if the unit is unused for over 72 hours?
Long-TermIdleUnder-Sink

After a long idle, first open a normal tap to drain muddy water, then power on and use the unit. If you're away on a long trip, close the inlet ball valve and cut power.

Troubleshooting

Faucet screen stays black?

Symptom
The smart faucet screen is black with no display.
Cause
The unit power is off, or the signal wire between faucet and unit is loose.
Solution
 ① Check the unit power plug and whether the outlet is live;  ② check the signal wire between faucet and unit. If still black, contact official service hotline 400-828-0808.

No ambient water from the faucet?

Symptom
Pressing the knob yields no water, or very little flow.
Cause
Inlet tee valve closed, wrong voltage, filter not seated, inlet water too cold, or a fault light on the faucet.
Solution
 ① If the faucet shows a "tap" icon, the supply is low — open the inlet valve;  ② confirm voltage matches the rating plate;  ③ check filters are pushed in (click sound);  ④ use municipal water at 5-35°C. If a fault light is on, contact official service hotline 400-828-0808.

No hot water?

Symptom
Selecting a hot level yields no hot water, or the water isn't hot.
Cause
Unit heating is off, the insulated tank is low (tank icon flashing), or the heating indicator is abnormal.
Solution
 ① Check whether the unit heating light is on; if the white light is on but no heat, call service;  ② if the tank is low, wait for it to refill before dispensing;  ③ if the tank won't refill, contact official service hotline 400-828-0808.

Odd taste in the water?

Symptom
The water has a plastic, disinfectant, or other off taste.
Cause
A filter is past its life, or stagnant residual water in the pipes after long idle.
Solution
 ① Check the filter-life indicator and replace any expired filter;  ② long-press the unit self-clean key to drain residual water and run several clean flushes before use. For a new unit, complete the full flushing process first.

Loud noise / vibration?

Symptom
Noticeable noise or vibration from the cabinet during purification or flushing.
Cause
Foreign matter blocking a tube, cabinet resonance, or abnormal booster-pump operation. Vibration during auto-flush is normal.
Solution
 ① Check the drain tube and faucet tube for blockages;  ② put a soft mat or cloth under the unit to reduce cabinet resonance;  ③ mild pump and flush vibration is normal. If the noise is clearly abnormal, contact official service hotline 400-828-0808.

Water leakage?

Symptom
Pudding or seepage at the unit bottom, pipes, or faucet joints.
Cause
A leak between the inlet valve and unit, or an internal unit leak.
Solution
 ① On finding a leak, immediately close the inlet tee ball valve and cut power;  ② external tube leaks can be fixed by replacing the valve or tube;  ③ internal leaks require official service hotline 400-828-0808 — authorized repair or factory return; never disassemble yourself.

E1 Inlet NTC fault?

Symptom
The faucet shows E1 and the unit stops.
Cause
Inlet water-temperature sensor (NTC) abnormal.
Solution
Power off and restart to try clearing it; if it recurs or won't clear, the sensor has failed — book on-site repair via official service hotline 400-828-0808.

E2 Heater-outlet NTC fault?

Symptom
E2 appears when dispensing hot water.
Cause
Heater outlet temperature sensor abnormal.
Solution
Power off and restart to clear; if it recurs, the sensor may have moisture or be damaged — contact official service hotline 400-828-0808 for repair or replacement.

E3 Insulated-tank NTC fault?

Symptom
The screen shows E3.
Cause
Insulated-tank temperature sensor abnormal.
Solution
Power off and restart to clear; if it keeps alarming, contact official service hotline 400-828-0808.

E4 Dry-boil NTC fault?

Symptom
The screen shows E4.
Cause
Dry-boil temperature sensor abnormal; dry-boil protection triggered.
Solution
Power off and restart to clear; make sure the tank is properly filled before using hot water. If it recurs, contact official service hotline 400-828-0808.

E5 Faucet NTC fault?

Symptom
The screen shows E5.
Cause
Faucet temperature sensor abnormal.
Solution
Power off and restart to clear; if it keeps alarming, contact official service hotline 400-828-0808 to inspect the faucet assembly.

E6 Booster-pump blockage alarm?

Symptom
The screen shows E6 and the unit won't purify.
Cause
Booster-pump blockage alarm, usually from a filter not seated or pipe buildup after long idle.
Solution
 ① Check all three filters are pushed in (click sound);  ② after long idle, open a normal tap to drain muddy water first, then power on. If it still alarms, contact official service hotline 400-828-0808.

E7 Overflow alarm?

Symptom
The screen shows E7.
Cause
Overflow protection triggered.
Solution
Long-press the faucet "Volume" key to enter drain mode, then press dispense to empty residual tank water, and power back on. If it still won't recover, the unit must be returned to the factory.

E8 Leak alarm?

Symptom
The screen shows E8 and the orange fault light is on.
Cause
The leak detector triggered, sensing an internal or external leak.
Solution
Immediately close the inlet tee ball valve and cut power; check the bottom and pipes for water. Power off and restart to try clearing; if it recurs, contact official service hotline 400-828-0808 for disassembly inspection — never open it yourself.

No purification after install?

Symptom
After new installation, the faucet has no water and the unit won't purify.
Cause
 ① No power;  ② cold-water tee valve not open;  ③ abnormal water connection;  ④ continuous-supply (tap) icon not enabled on the faucet.
Solution
 ① Confirm power and a live outlet;  ② check the under-sink cold-water tee valve is fully open;  ③ verify inlet/PE tube connections;  ④ confirm the continuous-supply (tap) icon is enabled on the faucet. If it still won't purify, contact official service hotline 400-828-0808.

Slow flow / low purified output?

Symptom
Ambient or purified output is clearly reduced.
Cause
 ① Inlet pressure low (under 0.15 MPa);  ② pre-filter/RO clogged;  ③ tee valve not fully open;  ④ PE tube kinked.
Solution
 ① Confirm inlet pressure meets spec; add a booster if low;  ② check filter life and replace as prompted;  ③ fully open the tee valve;  ④ tidy the under-sink tubes to avoid kinks.

Slow heating / temp won't reach set level?

Symptom
Set a high temperature but output runs cool; heating slows.
Cause
 ① Lower boiling point at high altitude;  ② tank hasn't recovered after heavy dispensing;  ③ tank not preheated at first power-on;  ④ inlet water too cold.
Solution
 ① At high altitude, rerun boiling-point detection;  ② wait for the tank to recover after heavy use;  ③ at first power-on, dispense one cup to preheat pipes;  ④ use 5-35°C inlet water. If it recurs, contact official service hotline 400-828-0808.

Steam / splatter when dispensing very hot water?

Symptom
Steam or splatter appears when dispensing very hot water.
Cause
At high altitude the boiling point drops, so more steam forms in the heater tube and exits with the flow.
Solution
Hold the container close to the spout when dispensing hot water; at high altitude watch for splatter on first use, and some areas may not be able to use the highest temperature level.

Self-clean won't start / stops midway?

Symptom
After triggering self-clean, the unit doesn't run or stops partway.
Cause
 ① No heat-resistant container under the spout;  ② abnormal water level/pressure;  ③ currently purifying or heating the tank.
Solution
Place a heat-resistant container under the spout, then trigger self-clean; it automatically drains ~100mL of 98°C water and stops after ~30s. Press again to cancel. If it still won't start, contact official service hotline 400-828-0808.

Filters wear out too fast?

Symptom
Filters last noticeably shorter than expected.
Cause
 ① Power-on time counts (once water flows, it counts even if unused);  ② high inlet TDS;  ③ heavy daily dispensing.
Solution
The life indicator is a recommended cycle, not mandatory — but don't wait until fully clogged, which can damage the booster pump. The H7's Hyper2.0 RO filter lasts 5-6 years.

Leak after filter replacement?

Symptom
Pudding under the unit or in the cabinet after changing a filter.
Cause
 ① Filter not pushed in / cover ring not closed;  ② didn't close the valve and relieve pressure first.
Solution
Always close the tee valve and relieve pressure before removing a filter. After replacing, push the filter in until it clicks and close the cover ring, then open the valve and check for leaks.

Spout keeps dripping?

Symptom
After closing the faucet, the spout keeps dripping.
Cause
Debris in a new-unit water path preventing the valve from sealing, or foreign matter in the faucet cartridge.
Solution
Open and close the faucet a few times and drain some water to flush the pipes. If it still drips, contact official service hotline 400-828-0808 to inspect the cartridge.

Knob unresponsive after child lock on?

Symptom
All dispensing keys are unresponsive and the screen shows the child-lock icon.
Cause
The child lock is engaged.
Solution
Long-press the faucet dispense/temperature knob for 5 seconds to turn off the child lock; after a beep and the icon disappearing, normal use resumes. It is off by default at first power-on and after a power cycle.

Cloudy first water after long idle?

Symptom
After being away for days, the first water from the faucet is cloudy or off-tasting.
Cause
Water sitting in the internal pipes has gone stale over a long idle.
Solution
After a long idle, first open a normal tap to drain muddy water, then power on the unit; we recommend draining 1-2 liters before drinking.

Insects found in the cabinet?

Symptom
Insects around or under the unit inside the cabinet.
Cause
The unit base has drainage guide holes (to protect safety against internal leaks); in a damp cabinet, insects may enter.
Solution
Keep the cabinet ventilated, dry, and regularly cleaned. The internal water path is fully sealed, so water quality is unaffected.

Water marks on a new unit's pump/valve?

Symptom
Small water marks on the bottom or pipes when unboxing a new unit.
Cause
100% performance and waterproof water-testing before shipping may leave minor marks.
Solution
This is normal; after the first installation flush, the unit is ready for use.

Low inlet-pressure alarm?

Symptom
Purification is intermittent, faucet flow is small, with a low-frequency alarm.
Cause
Inlet pressure below 0.15 MPa; the booster pump can't draw enough water.
Solution
Confirm the inlet tee valve is fully open; for high-rise or older buildings with low pressure, install a booster device before use.

Practical Self-Help Tips

Slow / no / intermittent purification — suspected trapped air

Symptom
Slow, no, or intermittent purification, suspected trapped air.
Solution
 ① Power on and wait for purification to start (pulsing sound); once done, open the top cover and pull out the filters;  ② use a chopstick to gently poke the hole at the bottom of each filter to release air (if the chopstick meets resistance, air is trapped — water may spray from the filter bottom, never point it at your face);  ③ do this for each filter, then screw filters back, wipe the counter, and close the cover.

Off/plastic taste on a new unit or after refill, even after repeated flushing

Symptom
Off or plastic taste on a new unit or after refill that persists despite repeated flushing.
Solution
 ① Open the top cover and pure-tank lid and air out for 24 hours;  ② if it remains, brew food-grade citric acid, pour into the pure tank to soak, then drain and flush 2-3 times;  ③ complete the full new-unit flush (cold drain 3-5 times + warm flush 1-2 times).

A few drops drip after removing the cup

Symptom
A few drops continue after removing the cup.
Solution
Dripping on a new unit usually comes from residual carbon dust or debris in the path; drain several times (3-5) and it normalizes. If it persists after a period of use, contact the store where you purchased.

White floating particles in dispensed water

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

Jumpy screen numbers / unresponsive or intermittent touch

Symptom
Jumpy numbers, unresponsive touch, or intermittent touch behavior.
Solution
 ① Wipe water off the screen — capacitive touch misfires when wet;  ② check for unstable voltage and try a dedicated outlet;  ③ if the screen still flickers, it may be a touch-film fault — contact official service hotline 400-828-0808.

Pressing dispense gives no water but the display is normal

Symptom
No water when pressing dispense, display otherwise normal.
Solution
 ① Check the top cover is fully closed (an unsecured cover triggers a safety lock);  ② cut power for 1 minute and reconnect;  ③ confirm the raw tank has water and the float floats;  ④ if all else fails, it may be a diaphragm-pump hardware fault — contact hotline 400-828-0808.

Does the pure tank need regular cleaning?

Symptom
Does the pure tank need regular cleaning? How?
Solution
We recommend cleaning the pure tank every 2-3 months:  ① remove the raw tank, open the top cover and pure-tank lid;  ② long-press "Dispense/Stop" 5s to drain (auto-stops);  ③ wipe the inside with a clean lint-free cloth;  ④ refill the raw tank and wait for auto-purification;  ⑤ long-press to drain 2-3 more times.

Intermittent flow with steam when dispensing hot water

Symptom
Intermittent flow with accompanying steam when dispensing hot water.
Solution
On models with swirl instant heating, water is heated to near 100°C as it passes the heater tube, producing steam that makes the flow finer and slightly intermittent vs ambient — normal. At high altitude the lower boiling point does the same; try dispensing at 85°C.

Insects at the unit bottom or around it

Symptom
Insects at the unit bottom or around it.
Solution
The base has drainage guide holes for safety; insects may enter when they are around.  ① Keep the unit clean, dry, and ventilated;  ② place a non-toxic repellent sachet near each of the four feet. The internal path is fully sealed, so water quality is unaffected.

Plastic smell remains after flushing — how to deep-deodorize

Symptom
Plastic smell remains after flushing; how to deep-deodorize?
Solution
Wetted plastic parts are deodorized at the factory, but a sealed pack may retain a slight smell — normal. Air out the pure tank for 12-24 hours and complete the flush. If it persists, use the "dish-soap method": dilute food-grade dish soap, circulate it in the pure tank, then drain and rinse 3-5 times with clean water. See the official video for details.

White scale / crystals on the raw-tank wall

Symptom
White scale/crystals on the raw-tank wall.
Solution
White powdery scale can appear on the raw tank over time — normal. To descale:  ① take a cup of ~65°C hot water, add 5-10g food-grade citric acid (adjust for severity), stir to dissolve;  ② fill the raw tank with tap water and pour in the solution;  ③ soak 30-60 minutes;  ④ wipe the wall with a clean cloth until scale comes off;  ⑤ dump the citric water and rinse thoroughly.

New filter outer packaging looks swollen / puffed

Symptom
New filter outer packaging looks swollen / puffed.
Solution
This is normal. Filters undergo airtight testing before shipping and are sealed with gas to preserve shelf state and filtration performance, so the pack may puff. As long as the seal is intact, it is safe. Bewinch uses double-seal packaging to keep filters clean in transit.

Loud pumping on the very first use

Symptom
Very loud pumping on the unit's first use.
Solution
This is normal. New filters and pump hold a lot of air; compressing it makes noise. Repeated purification and draining soaks the path, after which noise gradually drops. If it still sounds loud, check the unit sits level and add a soft mat under it to reduce resonance.

Black powder in the raw or pure tank on first flushing

Symptom
Black powder in the raw or pure tank on first flushing.
Solution
Normal. Activated-carbon filters are sintered from carbon powder and food-grade binder; a little carbon dust washes out on first use and is non-toxic. For black dust in the raw tank, flush the new unit 3-5 times; in the pure tank, rinse with tap water, wipe with a clean cloth, then drain and flush a few more times.

Cloudy raw-tank water with green or brown floaters

Symptom
Raw-tank water looks cloudy with green or brown floaters.
Solution
Usually algae spores or pipe sediment from an aging water mains — more noticeable in summer. The raw tank holds unpurified tap water, so cloudiness doesn't affect output: after the 0.0001-micron RO membrane, microbes, bacteria, and impurities are removed and the water is safe to drink directly. Clean the raw tank regularly.

Leak found at the unit bottom or around it

Symptom
Leak found at the unit bottom or around it.
Solution
 ① Immediately close the inlet valve (if any), stop supply, and cut power;  ② self-check: did any water splash during dispensing, or did the raw tank exceed the MAX line;  ③ open the top cover, check all three filters are seated, remove and reseat them in turn;  ④ wipe up water and power on to 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 dissolved substances in water; a higher number means more minerals and impurities. TDS is determined by your inlet water and is not fixed. Old water remains in internal pipes and filters, mixing with new water so readings may run a bit above tap water. After refilling, dispense a cup so the machine purifies and the TDS probe updates to the new water.

Why leftover raw-tank water gets more concentrated / what is waste water

Symptom
Why does leftover raw-tank water get more concentrated? What is waste water?
Solution
The RO membrane is 0.1nm precision; to stop impurities clogging the pores, some water flushes the membrane surface and returns to the raw tank as "waste." Waste water is only slightly saltier than tap water, not sewage. Each refill, dump all leftover raw water and fill fresh — don't reuse waste water.

Preset volume is slightly off by a little

Symptom
Preset dispensing is slightly less or more when measured in a cup.
Solution
A little water remains in the internal pipes, so preset volume has some tolerance — normal. Hot presets may deviate slightly more because flow speed changes with water temperature. Use a precisely marked measuring cup; this is within normal tolerance.

A vertical line / mark on the body shell

Symptom
A vertical line / mark on the body shell.
Solution
This is a natural weld line where plastic fuses during injection molding — an industry-wide phenomenon that doesn't affect use or looks. We continuously improve the process to minimize it.

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

Symptom
How is filter life calculated? Must I replace when the timer says?
Solution
Filter life is computed on three factors:  ① power-on time (like food expiry — it decays once water flows through, even unused);  ② inlet TDS (worse water = faster wear);  ③ total dispensed volume (more use = faster wear). The reminder is a recommendation, not mandatory — but don't wait until fully clogged, which can overload the booster pump or burst pipes.
