To manually activate the defrost cycle, hold down the key for 5 seconds.
If the defrost conditions are not satisfied:
- the parameter OdO ≠ 0 (EWPlus 902/961/971/974)
- the evaporator probe Pb2 temperature is higher than the defrost end temperature (EWPlus 971/974)
the display will flash 3 times, to indicate that the operation will not be carried out.

To switch off the buzzer, press and release any key, the relative icon will continue to flash.

signalled.

indication E1.
Models EWPlus 971/974: A probe 2 (Pb2) malfunction alarm will appear
directly on the display with the indication E2.
