Food is not cooked
(in baking sensor operation)
Vapour valve does not close completely.
-
If the vapour valve does not close completely, this can cause the baking sensor to
switch the appliance off prematurely. Food is not cooked enough.
►
Check the function of the vapour valve. (Page 76)
►
Replace vapour valve if defective. (Page 100)
►
Replace vapour valve motor if defective. (Page 101)
(for "Hot air eco"/"Top/bottom heating
eco")
Vapour valve does not close completely.
-
In these operation modes, only a little energy is supplied to the cooking
compartment. If the vapour valve does not close completely, energy will escape
outwards. Food will not be cooked enough. Baked goods will collapse and crumbs
will become greasy.

Food is heated too slowly
(for "microwave")
Not a fault.
► Advise customer:
When the microwave is being operated at high power, the output power is reduced
after 1 minute to prevent the appliance from overheating.
If the appliance has not cooled off sufficiently when it is restarted, only reduced
power will be generated despite a high power setting.
After the cooling fan has switched off, the power that is set will be available when
the appliance is restarted.
Cleaning action is inadequate
(for "EasyClean")
Vapour valve does not close completely.
-
The functioning principle of EasyClean is based on the condensation of the steam
on the surfaces of the cooking compartment. If the vapour valve does not close
completely, the steam escapes and is not available for condensation. The dirt
on the surfaces of the cooking compartment is not moistened sufficiently and is
therefore harder to wipe off.

Pieces of dough form a skin
(in the "dough proving setting"/"dough
proving setting with steam")
Vapour valve does not close completely.
-
If the vapour valve does not close completely, moisture will escape outwards.
The proving process will be disrupted and skin may form on the pieces of dough,
for example. This can make it more difficult to continue processing the pieces of
dough.
