Failure
The machine will
not start
The high pressure pump
is working properly,
but no water is being
produced
The storage tank is full
but no pure water is
fl owing out
The machine is turned off
but waste water has not
stopped
After the machine is fi lled
with water, the machine
starts repeatedly
Pure water fl ows slowly
or is not fl owing

TROUBLESHOOTING GUIDELINE

Reason
• Power source not connected
• Low inlet water pressure or no water
• Low-pressure switch failure,
cannot connect the power source
• High-pressure switch cannot
be restored
• Transformer is burned out
• High-pressure pump has lost
pressure
• Inlet water solenoid valve is
faulty, no water can get in (no
pure water)
• A pre-fi lter is clogged
• Non return valve is blocked
(waste water, no pure water)
• RO Membrane is clogged
• Storage tank doesn't have
enough pressure
• Post-activated carbon fi lter is
clogged
• Inlet solenoid valve failed, cannot
effectively cut off water supply
• Non return valve has lost pressure
(low waste water fl ow rate)
• Non return valve has lost pressure
• High-pressure switch failure
• Loss of pressure in the system
• Pre-fi lter is clogged
• RO membrane is clogged
• Inlet solenoid valve failure
• Non return valve is clogged
• Post-carbon fi lter is clogged
• High-pressure pump pressure is
not enough

Possible cause

• Check power source or power
source plug
• Check inlet water pressure
• After connecting the inlet water,
measure the resistance and
replace if needed
• After easing pressure, measure the
resistance and replace if needed
• Measure output voltage and
replace if needed
• Measure water pump pressure
and replace if needed
• Replace solenoid valve
• Check pure water and waste
water and replace the pre-fi lter
• Replace the non return valve
• Clean or replace the RO
membrane
• Infl ate the storage vessel and empty
tank; pressure should be
between 0.05 and 0.07MPa
• Replace the post-activated carbon fi lter
• Check waste water, replace the inlet
solenoid valve
• Check waste water, replace the non
return valve
• Replace the non return valve
• Replace the high pressure switch
• After checking the non return valve,
check for any water leaks in the
pipelines
• Replace the pre-fi lter
• Wash or replace the RO membrane
• Replace the inlet solenoid valve
• Replace the non return valve
• Replace the post-carbon fi lter
• Measure high-pressure pump water
pressure, replace if needed
