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 cakes
having very moist toppings (fruit), or
with very large roasts.
Energy pulses (e.g. lightning flash).
This kind of soiling is normal.
Remedy
Check teh 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.
Reset the relevant functions.
Detach the oven door and lay front
side down on a soft, clean 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.
