7. Troubleshooting, water pump conection
7.1 Error code display on wire controller
Error Code Malfunction Reason Solution
EE 01
High pressure failure
TS4
1. Ambient temperature is too high
2. Water temperature is too high
3. Water flow is too low
4. Fan motor speed is abnormal or fan
motor is damaged under cooling mode
5. Gas system jammed
6. High pressure wire is loose or
damaged
7. Too much refrigerant
1. Choose the silent mode.
2. Check the water flow or filtration
pump
3. Check the fan motor under cooling
mode, replace a new one if it is
abnormal.
4. Check and repair the refrigerating
system
5. Reconnect the high pressure wire or
replace a new high pressure switch
6. Check and repair the refrigerating
system
EE 02
Low pressure failure
TS5
1. EEV has blocked or pipe system is
jammed
2. Fan motor speed is abnormal or fan
motor is damaged under heating
mode
3. Gas leakage
4. Low pressure wire is loose or
damaged
1.Check the EEV and piping system
Check the motor
2. Check the fan motor under heating
mode, replace a new one if it is
abnormal
3. Check refrigeration system or check
the pressure value through the
high ‐ pressure gauge.
4. Reconnect the low pressure wire or
replace a new low pressure switch
EE 03 or
‘ON’
Water flow failure
TS1
1. The wiring of water flow switch is
loose or water flow switch damaged
2. No/Insufficient water flow.
1. Check the wiring of water flow switch
or change a new one.
2. Check the filtration pump or the
waterway system if there is air or
jammed inside
EE 04
Over heating
protection for water
temperature (d2 ‐
TH5) in heating
mode
1. Low water flow
2. Water flow switch is stuck and the
water supply stops
3. TH5 outlet water temperature
sensor is abnormal
4. The difference of outlet water
temperature and set temperature is
7
℃
or above in heating mode
1. Check the water flow switch if it
works well
2. Check the filtration pump or the
waterway system if there is air or
jammed inside
3. Check TH5 outlet water temperature
sensor or replace a new one.
4. Change the set temperature.
EE 05
d6 ‐ TH3 Exhaust too
high protection
1. Lack of gas
2. Low water flow
3. Piping system has been blocked
4. Exhaust temp. sensor failure d6 ‐ TH3
1. 5. Ambient temperature is too high
1. Check the pressure gauge, and fill
with some gas if it is lack of gas
2. Check the filtration pump or the
waterway system if there is air or
jammed inside
3. Check the piping system if there was
