Malfunction Error code Reason Solution
Low pressure
failure
EE02
1. EEV has blocked or pipe system is
jammed
2. Motor speed is a 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
Water flow failure
EE03
Or” ON”
1. Water flow switch is damaged
2. No/ Insufficient water flow.
1. Change the water flow switch
2. Check the water pump or the
waterway system
Over heating
protection for
water
temperature (T2)
in heating mode
EE04
1. Low water flow
2. Water flow switch is stuck and the
water supply is cut off
3. T2 sensor is abnormal
1. Check the water way system
2. Check the water pump or water
flow switch
3. CheckT2 sensor or change
another one
T6 Exhaust too
high protection
EE05
1.Lack of gas
2.Low water flow
3.Pipingsystem has been blocked
4.Exhaust temp. Sensor failure
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
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 anew 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 the waterway system
3. Check if the power in the normal
range
4. Check the phase sequence
