Table 2 Common Failures
Failure Description
Reason
Solution
The appliance does
not work.
1. Power failure.
2. Power cord is loose.
3. Control power fuse is broken.
1. Turn off the power switch and
check the power.
2. Find out the problem and fix it.
3. Replace the fuse.
The appliance has
low heating capacity.
1. Refrigerant is insufficient.
2. Water pipe's thermal insulation
performance is poor.
3. Dry filter is clogging.
4. The heat exchanger with air
has poor cooling.
1. Check if there is leakage and note
the standard quantity of refrigerant.
2. Strengthen water system
insulation function.
3. Replace the dry filter.
4. Clean heat exchanger with air.
The compressor
does not work.
1. Power supply or the controller
is broken.
2. The compressor's contactor
fails.
3. The wire is loose.
4. The compressor's overheating
protection works.
1. Find out the reason and solve it
accordingly.
2. Replace the contractor.
3. Find out the loose point and fix it.
4. Identify the reason of overheating and
then turn on the appliance after trouble
shooting.
The compressor
works noisily.
1. Internal components are
damaged.
2. Frozen oil is not enough.
1. Replace the compressor.
2. Add enough frozen oil.
The fan does
not work.
1. The capacitor is broken.
2. The screw is loose.
3. The motor is broken.
1. Replace the capacitor.
2. Tighten the screw.
3. Replace the motor.
The appliance does not
produce heat, while
the compressor is
working.
1. Refrigerant spreads out totally.
2. The compressor is broken.
1. Check if there is leakage and fulfill the
standard quantity of refrigerant.
2. Replace the compressor.
Discharge pressure is
too high.
1. Refrigerant is too much.
2. Fluorine-way system contains
non-condensable gas.
1. Expel excessive refrigerant.
2. Exclude non-condensable gas.
Suction pressure is
too low.
1. Dry filter is blocked.
2. Refrigerant is too little.
1. Replace the dry filter.
2. Check if there is leakage and fix it.
Non-Unit
Failure
1) There is water flow out of the drainage outlet of the safety valve:
When producing hot water, the cold water within the appliance is heated and expands,
so there is water flow out of the drainage outlet of the drain valve, which is normal case.
However, if there is water extruding continuously, that means the safety valve loses efficacy.
You should stop using the appliance and replace the safety valve as soon as possible.
2) The duration for heating a whole tank’s water becomes longer:
When the temperature is quite low in winter (e.g. 0℃), the heat pump’s performance
of producing hot water will not be as good as usual, so the duration for heating a whole
tank’s water becomes longer.
ATTENTION
If the appliance remains abnormal after you check as above, please contact the local service
center or dealer to send servicemen to repair the appliance promptly. Try to avoid the fuse fusing or
the leakage protector turning on and off back and forth.
