Settings
The factory default of 3:20 minutes can
be changed.
It can be set between 2:30 and
3:50 minutes.

Query food

The food prompt is a reminder that the
appliance should not be used without
food inside it.
Operating the appliance without food
can damage the appliance.
If a cooking programme has been
started without the door having first
been opened, the prompt
appears in the display.
It is possible that there is no food inside
the appliance because the door has not
been opened for a long time (approx.
20 minutes).
The programme only starts after
confirming with OK or after the door
has been opened.
