If the water purifier parts are damaged, it is recommended that the water purifier be
entrusted to the manufacturer or distributor, service center, or specialized technical
personnel for replacement to prevent loss caused by improper operation, the
manufacturer is not liable for losses caused by operation or use not in accordance with the
instructions and reminders.
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 power
source plug
Low water pressure or no water
Check the water pressure
Low-pressure switch failure, cannot
connect the power source
After connecting the water source,
measure the resistance, replace
High-pressure switch cannot reset
After letting off the pressure, measure
the resistance, replace
The transformer is 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 will not let water
in (no outlet water or wastewater)
Replace the inlet water solenoid valve
A pre-filter is blocked
Observe the output water and
wastewater, replace the pre-filter
The non return valve is blocked
(wastewater, no output water)
Replace the non return valve
The RO membrane is blocked
Clean or replace the RO membrane
The machine is
turned off but
wastewater has
not stopped
Inlet water solenoid valve failed, cannot
effectively cut off the water supply
Observe the wastewater, replace the
inlet water solenoid valve
The non return valve has lost pressure
(wastewater flow rate is low)
Observe the wastewater, replace the
non return valve
After the
machine is filled
with water, it
starts
repeatedly
The non return valve has lost pressure
Replace the non return valve
High-pressure switch failure
Replace the high-pressure switch
The system exhibits a loss of pressure
After checking the non return valve,
check whether there is water leakage in
the pipes
The output
water flow is low
or no water is
flowing
A pre-filter is blocked
Replace the pre-filter
The RO membrane is blocked
Clean or replace the RO membrane
Inlet water solenoid valve failure
Replace the inlet water solenoid valve
Non return valve is blocked
Replace the non return valve
High-pressure pump pressure is not
sufficient
Check the high-pressure pump output
water pressure, replace
