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
There is a general failure of all electri-
cal functions, i.e., the control lamps
have suddenly ceased to function.
Liquids or thin cake mixes are distri-
buted at a visibly uneven thickness.
The electronic timer display sudden-
ly shows a blinking 0.00.
The oven suddenly stop functioning.
The oven door window pane fogs
up.
A considerable amount of water
condensation occurs in the oven.
After prolonged use, the oven
window panes are soiled from the
inside.
Trouble-shooting Guide
Possible cause
Defective fuse.
The appliance has not been placed
or installed plumb-and-level.
The power supply was briefly inter-
rupted.
The electronic timer is set to an auto-
matic timing cycle.
This is a normal condition. It is cau-
sed by the occurrence of temperatu-
re differences.
This condition is normal with moist
cakes or with very large roasts.
This kind of soiling is normal.
Remedy
Check the fuse in the fuse box, and
replace if required.
Level the appliance using the level-
ling feet, or check the installation.
Reset the time of day.
Set the timer for operation without
automatic timing.
Heat the oven at 100 °C for about 5
minutes.
During baking or roasting, open the
oven briefly several times; wipe up
condensation after use.
Remove the oven door, and put
aside with the handle facing upward.
For cleaning, remove the two screws
at the door handle moulding with a
screwdriver.
Caution: During reassembly, install
both the door handle and the door
seal in their original positions.
