damaged
3. Gas leakage
1. Water flow switch is damaged
EE03 2. No/ Insufficient water flow.
Or" ON"
1. Low water flow
2. Water flow switch is stuck and the
water supply is cut off
EE04
3. T2 sensor is abnormal
1.Lack of gas
2.Low water flow
3.Pipingsystem has been blocked
4.Exhaust temp. Sensor failure
EE05
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

Solution
1. Check the EEV and piping
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
