Trouble-shooting Guide
Calling the customer service is not always really necessary. In some cases, you can remedy the situation your-
self. The following table may contain some helpful tips.
Important general safety guidelines:
Service or repair work on the electronic components may only be performed by a qualified expert. Without exception, prior
to starting such repairs, the appliance must be disconnected from the mains. This may be accomplished by tripping the
automatic fuse or by removing the fuse from the fuse box that controls your flat or apartment.
Problem

Remedy
There is a general failure of all electri-
cal functions, i.e., the control lamps
have suddenly ceased to function.
Defective fuse.
Check the fuse in the fuse box, and
replace if required.
Liquids or thin cake mixes are distri-
buted at a visibly uneven thickness.
The appliance has not been placed
or installed plumb-and-level.
Level the appliance using the level-
ling feet, or check the installation.

sed by the occurrence of temperatu-
re differences.
Heat the oven at 100 °C for about 5
minutes.

condensation occurs in the oven.
This condition is normal with moist
cakes or with very large roasts.
During baking or roasting, open the
oven briefly several times; wipe up
condensation after use.

window panes are soiled from the
inside.
This kind of soiling is normal.
Remove the oven door
and lay

base.
Grip the
door glass
near the hinges,
pull up and remove.
Doors with 3 panels:
Disengage
inner door glass
at the
corner pieces and lift it up using, for
example, a pair of frying tongs made
of plastic or wood.
Installing the cleaned glass:
Insert the
inner door glass
and lock
into position.
Attach the
door glass
and lock into
position by pressing the glass near
the hinges.
