code
1. EEV has blocked or pipe system is
jammed
2. Motor speed is abnormal or motor has
EE02
damaged
3. Gas leakage
1. Water flow switch is damaged
EE03
Or" ON" 2. No/ Insufficient water flow.
1. Low water flow
2. Water flow switch is stuck and the
EE04
water supply is cut off
3. T2-TH5 sensor is abnormal
1.Lack of gas
2.Low water flow
EE05
3.Piping system has been blocked
4.Dischargetemp. Sensor failure
1. Wire connection is not good, or
damaged signal wire
2. Controller failure
EE06
1. The compressor current is too large
instantaneously
2. Wrong connection for compressor
phase sequence
EE07 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
Reason

Solution
1. Check the EEV and piping
system Check the motor
2. Through the high pressure
gauge to check the pressure value
Check refrigeration system
1. Change the water flow switch
2. Check the filtration pump or the
waterway system
1. Check the water way system
2. Check the filtration pump or
water flow switch
3. Check T2-TH5 sensor or replace
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
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
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
