Safety features
Control panel
42
The electronics of the control panel are equipped with
overheating protection. This switches off the heating element
automatically before the electronics overheat.
The fault message FE37 will be displayed.
Once the electronics have cooled off sufficiently, the fault
message will disappear and you will be able to operate the
cooktop normally.
The overheating protection mechanism may be switched on if
more than one cooking zone is operated on a high setting for
a longer period of time.
