Troubleshooting

Faults with indication (Self diagnosis function)

If a fault occurs during operation, the LEDs flash for an extended period or an error code is displayed (e.g. EH 02).

If a fault is present for more than 10 minutes:

• Briefly disconnect the power supply and switch the indoor unit back on.

If a fault persists:

• Call customer service and provide the fault code and details of the appliance.

Faults not indicated

If faults occur during operation that cannot be eliminated:

• Call customer service about the fault, providing details of the device.

Fault	Possible cause
The output of the indoor unit is too low.	Temperature is set too high or too low.
	Air filter is soiled and must be cleaned.
	Unfavourable ambient conditions for the indoor unit, e.g. the ventilation openings of the devices are obstructed, doors/windows in the room are open or the room contains powerful heat sources.
	Low-noise operation is activated and prevents the full output from being used.
Indoor unit does not switch on.	The indoor unit has a safety mechanism to prevent overloading. It may take 3 minutes, until the indoor unit can be restarted.
	The batteries of the remote control are empty.
	The timer is switched on.
Operating mode changes from Cooling or Heating to Fan Mode.	The indoor unit changes operating mode to prevent the formation of frost.
	The set temperature is reached provisionally.
A white mist is coming from the indoor unit.	In humid regions, white mist may appear if there is a significant temperature difference between the indoor air and air-conditioned air.
White mist is emerging from the indoor unit and outdoor unit.	If heating mode is activated directly after automatic defrosting, this can generate white mist due to the higher level of humidity.
There is noise coming from the indoor unit and outdoor unit.	A swooshing noise may be heard inside the indoor unit if the position of the airflow grille is set back.
	A quiet hissing noise is normal during operation. This is caused by the flow of refrigerant.
	Creaks and squeaks may be heard, as the metal and plastic parts of the device expand or contract during heating/cooling.
	The outdoor unit also emits a range of other noises during operation which is normal.
Dust is being discharged from the indoor unit or outdoor unit.	Dust may accumulate in the devices if they are shut down for an extended period and not covered.
Unpleasant odour during operation.	Unpleasant odours in the air may enter the devices and spread.
	There may be mould on the air filter and it must therefore be cleaned.
The fan of the outdoor unit is not running continuously.	Variable fan control is used to ensure optimum operation.
Operation is irregular or unpredictable or the indoor unit is not responding.	The indoor unit may be affected by interference from mobile radio masts or external signal amplifiers. Briefly disconnect the indoor unit from the power supply then restart it.
Air baffle or louvres do not run correctly.	Air baffle or louvres have been adjusted manually or have not been correctly installed. Switch off the indoor unit and check whether the components are engaged correctly. Power on the IDU.
