Cleaning system

The cleaning system regenerates the self-cleaning surfaces in
the cooking compartment.
The self-cleaning surfaces are coated with a highly porous
ceramic layer. This coating absorbs and disintegrates splashes
from baking and roasting while the oven is in operation. If the
surfaces no longer clean sufficiently and dark stains appear,
they can be regenerated with the cleaning system.
Retrofitting the self-cleaning ceiling and side walls
The back wall in the cooking compartment is coated with
ceramic. In order for you to be able to use the cleaning system,
the ceiling and side walls must also be coated. You can obtain
the self-cleaning ceiling and side walls as a special accessory
from the after-sales service.
Changing the basic settings
When you have retrofitted the self-cleaning ceiling and side
walls, you must activate the cleaning system in the basic
settings. To find out how to do this, refer to the Basic settings
section.
Cleaning levels
You can choose from three cleaning levels.
Level Degree of cleaning
1 gentle
2 moderate
3 intensive

Before cleaning

Remove accessories and cookware from the cooking
compartment.
Cleaning the cooking compartment floor
Before you set the cleaning system, clean the surfaces in the
cooking compartment that are not self-cleaning. Otherwise,
stains will develop that it is not possible to remove.
Use a dish cloth and hot soapy water or a vinegar solution. If
there are heavy deposits of dirt, use a stainless steel scouring

Care and cleaning

With good care and cleaning, your oven will remain clean and
fully-functioning for a long time to come. Here we will explain
how to maintain and clean your oven correctly.
Notes
Slight differences in the colours on the front of the oven are
■
caused by the use of different materials, such as glass,
plastic and metal.
Shadows on the door panel which look like streaks, are
■
caused by reflections made by the oven light.
Enamel is baked on at very high temperatures. This can
■
cause some slight colour variations. This is normal and does
not affect their function. The edges of thin trays cannot be
completely enamelled. As a result, these edges can be
rough. This will not impair the anti-corrosion protection.

Cleaning agents

To ensure that the different surfaces are not damaged by using
the wrong cleaning agent, observe the information in the table.
