working, replace the pump
- In areas with hard water ensure Gas Cooler
is not scaled up, descale if necessary
- Remove debris from the evaporator coil
(e.g. leaves, grass, snow)
- Replace the ambient temperature thermistor
- Replace the defrost thermistor
- Check if the thermistor is mounted
in position on the evaporator
- Replace the defrost thermistor
- Check the thermistor connectors on the
main PCB in the heat pump unit for any
disconnect, wire breakage or short circuit
- Measure resistance of the specific
thermistor indicated by the error code
- Reconnect the connector, check if it is off
the PCB
- Ensure Fan Blade is not caught on debris or
snow/ice build-up inside the unit
- Replace the fan motor
- Check the heat pump piping for blockage or
kinking
- Confirm that the connector for the water
circulation pump is connected to the PCB
correctly
- Replace the water circulation pump
- In areas with hard water ensure piping is not
scaled up, descale if necessary
Replace the PCB
(In the case of E080, check the heat pump
piping for blockage/debris, any piping bend,
blockage or kinking and pipes are not frozen )
