INCIDENT AND TROUBLESHOOTING
SYMPTOM | CAUSE | SOLUTION |
Pump not working | Power not supplied
Adaptor damaged Low-pressure switch not closing due to weak pressure | Check power source
Check Adaptor Check key lock, water supply |
Pump operates unevenly with continuous noise | Insufficient water pressure
Filter core blocked | Increase water supply pressure regularly > 0.3 bar
Replace filter core Increase water supply pressure regularly > 0.3 bar Replace filter core |
Pump operates continuously but no pure water and wastewater | Electronic valve malfunction
No water supplied | Check electrical wires
Replace electronic valve Check key lock, water supply |
Excessive wastewater (Rare) | Insufficient pump pressure
R.O membrane closed | Check pump and R.O membrane (pump pressure should be between 60PSI and 90 PSI) |
Unusual taste in drinking water (Rare) | Activated carbon filter expired (filter number 5) | Replace filter number 5 (T33) |
Water leakage from the machine (Rare) | Incorrect or improperly fitted joints | Tighten joints or replace |
Insufficient or no wastewater (Rare) | Wastewater restrictor clogged | Replace restrictor valve, limit wastewater (Flow) |
Unusual taste in drinking water (Rare) | Activated carbon filter expired (filter number 5) | Replace filter number 5 (T33) |
Water tank full but low water output (Rare) | Pressure in the tank not exhausted or too weak | Check the storage tank
Check the tank pressure |
Water in the tank is consumed when not in use (Rare) | Check valve malfunction | Check or replace the check valve |
Excessive pure water compared to wastewater (Rare) | R.O membrane damaged
Defects in membrane casing (usually pure water conductivity < 40 ppm) | Replace R.O membrane or membrane casing |
Pump leaking water or making noise (Rare) | Check gaskets, bearings | Repair or replace the pump |
