7. Troubleshooting
7.1 Error code display on LED wire controller
Error Code Malfunction Reason Solution
EE 01
High pressure
failure
1. High pressure switch in bad
connection or failure
2. Ambient temperature is too
high
3. Water temperature is too
high
4. Water flow is too low
5. Fan motor speed is abnormal
or fan motor has damaged
1. Check the wiring for high pressure
switch or change a new one
2.Check the water flow or water pump
3. Check the fan motor
4. Check and repair the piping system
EE 02 Low pressure failure
1. Low pressure switch in bad
connection or failure
1. EEV has blocked or pipe
system is jammed
2. Motor speed is abnormal or
motor has damaged
3. Gas leakage
1. Check the wiring for low pressure
switch or change a new one
2. Check the EEV and piping system
Check the motor
3. Through the high pressure gauge to
check the pressure value
EE 03 Water flow failure
1. Water flow switch is in bad
connection
2. Water
flow switch is
damaged
3. No/ Insufficient water flow.
1. Check the wiring for water flow switch
2. Change the water flow switch
3. Check the water pump or the
waterway system
EE 04
Over heating
protection for water
temperature (T2) in
heating mode
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. Check T2 sensor or change another one
EE 05
Exhaust
temperature (T6)
too high protection
1. Lack of gas
2. Low water flow
3. Piping system 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
EE 06
Controller
malfunction
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
EE 07
Compressor current
protection
1. The compressor current is
too large momentary
2. Wrong
connection for
compressor phase sequence
1. Check the compressor
2. Check the waterway system
3. Check if the power in the normal range
4. Check the phase sequence connection
