Pre-heating the oven
The Booster function is used to quickly
heat up the oven compartment in some
functions.
The Pre-heat function can be used with
any function (except
Microwave
 ) and
has to be switched on separately for
each cooking programme.
If you have set a cooking duration, it will
only start to count down when the
target temperature is reached and you
have placed the food in the oven.
It is only necessary to pre-heat the oven
in a few instances.
 Most dishes can be placed in a cold
oven. They will then make use of the
heat produced during the heating-up
phase.

Pre-heat the oven for the following
preparations and oven functions:
– Dark bread dough and beef sirloin
joints and fillet with the Fan
Plus
 and
Conventional
Heat  functions
– Cakes and pastries with a short
cooking duration (approx. 30 minutes
or less) as well as delicate items (e.g.
sponge) with the
Conventional
Heat
 function (without the
Booster
function)
Booster
The
Booster
function is used to quickly
pre-heat the oven compartment in
some functions.
This function is switched on as the
factory default setting for the following
functions (
Settings | Booster | On ):
– Fan Plus 
– Conventional Heat

– Auto Roast 
– MW + Fan Plus

– MW + Auto Roast 
If you set a temperature above 100 °C
and the
Booster
function is switched on,
a rapid heating-up phase heats the
oven compartment to the set
temperature. The top heat/grill element
and the ring heating element come on
together with the hot air fan.
Delicate items (e.g. sponge or
biscuits) will brown too quickly on
the top if the
Booster
function is
used.
Switch off the
Booster function for
these items.
