Malfunction
Error
code
Reason
Solution
Low pressure failure
TS5
EE02
1. EEV has blocked or pipe system is
jammed
2.
Motor speed is abnormal or motor has
damaged
3. Gas leakage
1. Check the EEV and piping
system Check the motor
2.
Through the high pressure
gauge to check the pressure value
Check refrigeration system
Water flow failure
TS1
EE03
Or” ON”
1. Water flow switch is damaged
2. No/ Insufficient water flow.
1. Change the water flow switch
2. Check the filtration pump or the
waterway system
Over heating
protection for water
temperature
(T2-TH5) in heating
mode
EE04
1. Low water flow
2. Water flow switch is stuck and the
water supply is cut off
3. T2-TH5 sensor is abnormal
1. Check the water way system
2. Check the filtration pump or
water flow switch
3. Check T2-TH5 sensor or replace
T6-TH3 Dischargetoo
high protection
EE05
1.Lack of gas
2.Low water flow
3.Piping system has been blocked
4.Dischargetemp. Sensor failure
1. Check the high pressure gauge,
if too low, fill with some gas
2. Check the waterway system and
filtration pump
3.
Check the piping system if there
was any block
4. Change a new Dischargetemp.
sensor
Controller failure
EE06
1. Wire connection is not good, or
damaged signal wire
2. Controller failure
1.
Check and re-connect the signal
wire
2. Change a new signal wire
3. Turn off electricity supply and
restart machine
4. Change a new controller
Compressor current
protection
EE07
1. The compressor current is too large
instantaneously
2. Wrong connection for compressor
phase sequence
3.Compressor accumulations of liquid and
oil lead to the current becomes larger
4. Compressor or driver board damaged
5. The water flow is abnormal
6. Power fluctuations within a short time
1. Check the compressor
2. Check compressor phase
3.
Check if the power in the
normal range
4. Check the phase sequence
connection
5. Check the waterway system and
filtration pump
6.
Check mains power input
