Common Faults and Debugging
◎
The user must hire the professional maintenance staff to fix if the unit has any problems
during working. The maintenance staff might refer to the chart to debug.
Error Status Possible reason Solution
Heat pump not
running
Power fault
Wiring loose
Fuse blow fused
Thermal Overloaded protector off
Low pressure too low
Put off the power switch, check the
power supply
find out the causes and repair
Replace the fuse blow
test the voltage and current
Water pump is
working but without
water cycle or
water pump high
noise
Lack of water in the system
with air in the water system
the valves are not all open
filter is dirty and blocked
Check the system replenishment
device and replenish the system
discharge the air in the water system
Open the water system valve
Clean the water filter
Low heating
capacity
Lack of refrigerant
Bad heat preservation of water
system;
Dry filter blocked
Bad heat dissipation of air heat
exchanger
Not enough water flow
Leakage detecting and supply
refrigerant
Reinforce the heat preservation of
water system
Change the dry filter
Clean the air heat exchanger
Clean the water filter
Compressor not
working
Power failure;

Find out the loose point and repair
Check the unit pressure and Exhaust
gas temp.
Reset the outlet water temp
Clean the water filter and discharge
the air in the system
Check the running current and whether
overload protector damage
compressor
running noise too
high
Liquid refrigerant enter the
compressor
The inner parts of compressor
damage
Too Low voltage
Check the expansion valve whether
out of effect
Replace the compressor
Check Power Voltage
Fan not working
The fastening screw of the fan
loose
Fan motor damage
Contactor damage
Reinforce the screw
Replace the fan motor
Replace the contactor
Compressor
running but heat
pump not heating
Refrigerant is all leaking out
Compressor fault
Compressor reversal
Check leakage and charging the
refrigerant
Replace the compressor
Exchange the phase order of
compressor
Low water flow
protection
Not enough water flow in the
system
Water switch fault
Clean the water filter and discharge
the air in the system
Check the water switch and replace it
