10. Trouble shooting guideline
Failure
Experienced
Reason
Possible root cause
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 if
needed
High-pressure switch cannot be
restored
After letting off the pressure, measure
the resistance, replace if needed
Transformer is burned out
Measure the output voltage, replace if
needed
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 if needed
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 storage tank
is full but no pure
water is flowing
out
Storage tank doesn’t have enough
pressure
Inflate the storage bucket, empty tank
pressure should be between 0.05 and
0.07MPa
Post-activated carbon filter is plugged
Replace the post-activated carbon
filter
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
Non return valve has lost pressure
Replace the non return valve
High-pressure switch failure
Replace the high pressure switch
