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
'ON'
or
EE03
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

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
