GB 18
The cooking zone only reacts if a suitable pan is placed on it.
If there is just a spoon or a fork on the cooking zone, the
cooking zone does not switch on.
The displays of cooking settings continue to flash.
The electronics have to be cooled. Cool air is drawn in behind
the kitchen cupboard and blown out again under the hob. The
appliance is only able to function, therefore, if sufficient air
can circulate.
When there is insufficient air circulation, the appliance
switches itself off after a short time.
