Failure Diagnosis and Resolution
Failure
Experienced
Reason Resolution Method
The machine
will not start

The power source is not connected

Check the power source or the
power source plug

Low inlet water pressure or no water

Check the inlet water pressure

Low-pressure switch failure, cannot
connect the power source

After connecting the inlet water,
measure the resistance, replace

High-pressure switch cannot be restored

After letting off the pressure,
measure the resistance, replace

Switch Mode Power supply is burned out

Measure the output voltage,
replace

Fuse in the computer box burned out

Measure the output voltage,
replace
The high
pressure pump
is working
properly, but no
water is being
produced

High-pressure pump has lost pressure

Measure the water pump pressure,
replace

Inlet water solenoid valve is faulty, no water
can get in (no pure water)

Replace the solenoid valve

A pre-filter is blocked

Observe the pure water and waste
water, replace the pre-filter

Non return valve is blocked (waste water,
no pure water)

Replace the non return valve

The RO Membrane is plugged

Clean or replace the RO membrane
The machine is
turned off but
waste water has
not stopped

Inlet solenoid valve failed, cannot
effectively cut off the water supply

Observe the waste water, replace
the inlet solenoid valve

Non return valve has lost pressure (small
waste water flow rate)

Observe the waste water, replace
the non return valve
After the
machine is filled
with water
(stand by), the
machine starts
repeatedly

Non return valve has lost pressure

Replace the non return valve

High-pressure switch failure

Replace the high pressure switch

System is exhibiting a loss of pressure

After checking the non return valve,
check whether there is water
leakage in the pipelines
The pure water
flow is small or
not flowing

Pre-filter is plugged

Replace the pre-filter

RO membrane is plugged

Wash or replace the RO membrane

Inlet solenoid valve failure

Replace the inlet solenoid valve

High pressure pump pressure is not
enough

Measure the high pressure pump
water pressure, replace
