Problem
Possible cause
Remedy
The Booster has
deactivated early
automatically.
The overheating
protection mechanism
has triggered.
See "Overheating protection".
The cooking zone is
not working in the
usual way at the power
level set.
Power level 9 is
automatically reduced
if you select power
level 9 on two linked
cooking zones or
extended zones at the
same time.
Operating both zones
at power level 9 would
exceed the permitted
maximum power level
for the two zones.
The hob switches off
while it is in use, an
F
appears in every
cooking zone display
and a tone sounds.
One or more of the
sensors have been
covered, e.g. by finger
contact, food boiling
over or by an object
such as an oven glove.
Clean the control panel or
remove the obstruction (see
"Safety switch-off").
The food in the pan
hardly heats up or does
not heat up at all when
the Auto heat-up
function is switched
on.
There is too much food
in the pan.
Start cooking at the highest
power level and then turn
down to a lower one manually
later on.
The pan is not
conducting heat
properly.
The cooling fan
continues to run even
after the appliance has
been switched off.
The fan will continue
running until the
appliance has cooled
down. It will then
switch itself off
automatically.
