6. TROUBLESHOOTING
SUGGESTIONS
1. Check whether power is cut
2. Contact authorized service
personnel for repair.
3. Make sure the grounding is
reliable.
1. Rotate “TEMP” knob
2. Repair or replacement
of the PCB
1. Press the reset handle
of the thermal sensor
after checking and
troubleshooting
2. Change the heating
element
3. Adjust water flow
4. Change the flow sensor
5. Open the flow sensor
and clean the rotor
1. Wait for restoration of
running water supply;
2. Open the inlet valve of
running wate r.
Lower the heating power and
increase the water flow.
Contact authorized service
personnel for repair.
Contact authorized service
personnel for repair.
REASONS
1. Power supply error,
2. PCB error;
3.
4.
Occurence of leakage current
There is no ground electrode or
incorrect ground connection
1. The “TEMP” knob is off;
2.
3. The water flow
is below 1.2L/min;
PCB error ;
4. Impurities clogging the
flow sensor of the rotor
1. The running water
supply is cut off;
2. The inlet valve of running
water is not open.
1. Water p ressu re is not
stable.
2. Outlet water temperature
is too high, overheating
protection activates repeatedly
Occurence of electrical
current leakage.
PUMP malfunction.
Temperture sensor
is broken
Change the temperture
sensor

5. MAINTENANCE
DECLARATION:
this water heater can only be maintained by authorized service personnel.
Incorrect installation and use may cause serious injury or loss of property.
WARNING
Do cut off power supply before maintenance, to avoid danger such as electric shock.
!
This electric water heater should be installed in a place without direct sunshine or where
rainwater will not hit the unit. Please cut off power supply if the unit will not be used for a
long period of time.
Please run the water for about 10 seconds to drain away the impurities in the pipe before
connecting the water source to the electric water heater, to avoid clogging.
If the unit has not been used for a long time, check it first before using it again. Turn on the
unit only after water constantly flows out of the shower head.
Do not spray water to the circuit breaker or heater body directly, to avoid moisture formation.
Please cut off the power during inclement weather to avoid damaging the water heater.
If the unit will not be used for a long period of time, turn off the water supply to the water heater,
to prolong its life.
Check the power cord connecting terminals frequently to make sure that these are well and
reliably contacted, no occurence of overheating phenomenon, and grounding is good.
Disassemble the shower head and sealing ring with filter, for periodic cleaning.
