current protection
1. EEV has blocked or pipe system is
jammed
EE02
2. Motor speed is a abnormal, or
motor has damaged
3. Gas leakage
EE03 1. Water flow switch is damaged
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 sensor is abnormal
1.Lack of gas
2.Low water flow
EE05
3.Pipingsystem has been blocked
4.Exhaust temp. Sensor failure
1. Wire connection is not good, or
EE06 damaged signal wire
2. Controller failure
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
EE07
larger
4. Compressor
damaged
5. The water flow is abnormal
6. Power fluctuations within a short
time
Reason
or driver board

Solution
1. Check the EEV
system Check the motor
2. Through the high pressure gauge
to check the pressure value
1. Change the water flow switch
2. Check the water pump or the
waterway system
1. Check the water way system
2. Check the water pump or water
flow switch
3. CheckT2 sensor or change
another one
1. Check the high pressure gauge,
if too low, fill with some gas
2. Check the waterway system and
water pump
3. Check the piping system if there
was any block
4. Change a new exhaust temp.
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 anew controller
1. Check the compressor
2. Check the waterway system
3. Check if the power in the normal
range
4. Check the phase sequence
connection
and piping
