Cause and remedy
The door is not properly closed.
 Close the door.
The door seal is not correctly fitted.
 Press it in all the way round the door to make sure
it is fitted evenly.
The door seal is damaged, e.g. cracks can be seen.
The door seal needs to be replaced.
 Call Miele Service.
 Do not use any microwave modes / functions until
the door seal has been replaced.
When the door is closed, the pressure has to equal-
ise, which can cause a whistling sound. This is not a
fault.
Finish at
The temperature in the oven compartment is too high,
e.g. after a programme has finished.
 Open the door and let the oven compartment cool
down.
These functions are not generally available in main-
tenance programmes.
The steam oven with microwave is a fully fledged
steam oven. The cooking compartment is completely
hermetically sealed. In contrast, a conventional
microwave oven is not air-tight. Because the cooking
compartment is steam-tight, condensation will form
on the side walls and the inner door panel during
long cooking programmes using microwave power
. The amount of condensate depends on the
cooking duration and the level of moisture in the
food.
