Description of functions
Steam reduction
If a cooking temperature above approx.
80 °C has been set, the appliance door
will automatically open a fraction just
before the end of a cooking programme
to release some of the steam from the
cabinet.

the display. The door will then close
again automatically.
Steam reduction can be switched off if
you wish (see "Settings - Steam reduc-
tion"). If switched off there will be a lot
of steam emitted from the cabinet when
the door is opened.
Microwave power
How it works
In the steam oven with microwave there
is a high-frequency tube called a mag-
netron. This converts electrical energy
into microwaves. These microwaves are
distributed evenly throughout the oven
interior, and rebound off the metal sides
of the oven interior to reach the food
from all sides.
In order for microwaves to reach the
food, they must be able to penetrate the
cooking utensil being used. Microwaves
can penetrate porcelain, glass, card-
board and plastics, but not metal. Do
not, therefore, use utensils made of
metal, or which contain metal, for ex-
ample in the form of gold or silver trim.
The metal reflects the microwaves and
this could cause sparking. The mi-
crowaves cannot be absorbed.
Microwaves pass through a suitable
container and find their way directly into
the food. All food contains moisture
molecules which, when subjected to
28
will appear in
microwave energy, start to oscillate
2.5 thousand million times a second.
The friction caused by this vibration
creates heat, which first starts develop-
ing around the outside of the food and
then slowly penetrates towards the
centre. The moisture, fat and sugar
content of food will affect the speed at
which it is cooked. The heat is gener-
ated in the food itself.
Advantages
Food can generally be cooked without
adding much liquid or cooking oil.
Microwaves stop being produced as
soon as the cooking process is inter-
rupted or the appliance door is
opened. When the appliance is in op-
eration, the closed, sealed door pre-
vents microwaves escaping from the
appliance.
