Cause and remedy
This is not a fault.
The compressor (heat pump) is operating or you have
selected the Steam smoothing programme.
 No action is required. These noises are quite nor‐
mal and can be heard when the compressor or the
condensed water pump is operating.
No obvious cause.
 Connect the tumble dryer to the mains
 Turn on the tumble dryer
 Close the door
 Check whether the mains fuse has tripped
Has there been a power cut? When power is restored
any previously running programme will restart auto‐
matically.
The dryer is in standby mode. This is quite normal
and does not indicate a fault.
The drum will turn at intervals in the anti-crease
phase.
 See "Settings menu, Dark display".
The dryer switched off automatically. This is quite
normal and does not indicate a fault.
 See "Settings menu, Appliance switch-off".
The drum lighting will switch off automatically ...
... when the door is closed.
... after a few minutes when the door is open (to save
energy).
If the dryer is switched on, the drum lighting will
come on when the door is opened.

blocked.
