5. MAINTENANCE
In the event of a problem, the heat pump’s screen displays an error code instead of temperature
indicaons. Please consult the table below to nd the possible causes of a fault and the acons
to be taken.
In case of malfuncon or a fault code is displayed, restart the heat pump. If the problem persists,
please contact a professional.
WARNING: Under normal condions, a suitable heat pump can heat up the tub water
by 1 °C to 2°C per hour. It is therefore normal that you do not feel any dierence in
temperature at the outlet level when the heat pump is on.
Code Descripon Soluon
E03 Water ow protecon Check water ow switch, change the switch if necessary
E04 Winter an-freezing
Water pump will run automacally for rst grade
anfreeze
E05 High pressure protecon
Measure the pressure value when heat pump is heang
(cooling), if it’s higher than 44.0 bar, it means heat pump
has got really higher pressure protecon:
1. Detect EEV step, low pressure and sucon temp;
2. Detect the inlet/outlet water temp.;
3. Maybe there is some air in the refrigeraon system;
4. Clean the water exchanger or water lter
E06 Low pressure protecon
(According to actual model) Measure the pressure value
when heat pump is heang(cooling), if it’s lower than 6
bar, it means heat pump has got really lower pressure
protecon:
1. Maybe there is some leakage in the refrigeraon
system.
2. Ambient temp. is too low.
3. There is some blockages on the refrigerant system.
4. Clean the n heat exchanger.
E09
Communicaon fault between display
and PCB
1.Check if the communicaon connecon wire between
display and PCB is well. Change or mend the wire if
necessary. Check the PCB or display. If damaged, Change
the corresponding part.
E10
Communicaon fault of frequency
conversion module (alarm when
communicaon between display and
PCB is disconnected)
Change PCB.
