PROTECTIVE EQUIPMENT
CLEANING
Cleaning
Although spillage cannot "burn on", the
surface should still be cleaned immediately
after use.
In order to remove stubborn marks, use a little
mild cleaning agent (e.g. washing up liquid).
Water marks and traces of lime can most
easily be removed with the aid of vinegar.
Metallic traces, usually resulting from sliding
the pans across the ceramic surface, are
often difficult to remove. Special products are
available on the market to deal with this.
■ Never use abrasive products which cause
fine scratches where lime traces and dirt
can collect.
■ Never use sharp objects such as steel wool
or abrasive sponges.
Protective equipment
Several different protective devices are built
into the hob to protect your cooking utensils
and the electronics. When the hob is built in
correctly the protective equipment will react
seldom or never.
Detection protection
The cooking zone reacts only if there is a
suitable pan standing on it. If there is only a
spoon or a fork on the cooking zone it will not
switch on. The lights will continue to flash.
The appliance will switch itself off also if two
pans touch each other or if one pan comes in
contact with a wall. Ensure thus that the pans
are "free".
Ventilation protection
The electronics must be cooled. Cool air will
be drawn in from behind the kitchen cabinet
and blown out from the front below the work
top. The appliance can therefore only function
when sufficient air can circulate. If the
ventilation flow is insufficient the hob wil not
switch on.
Overheating protection
Three protective devices are built into the hob
to protect it against overheating.
The first device protects the electronics. If the
electronics temperature rises too high, this
device will act. The hob will be switched off.
The fan will continue to run to cool the hob. F7
will appear in the display. Press any button
and the message will disappear. Switch on the
hob again and select a lower power.
The second device protects your pans. This is
done by checking the temperature of the
ceramic plate. It is important for this device
that the bottom of the pan is flat. If the
temperature is too high the hob automatically
switches to a lower power. If this device
should be defective F1 and F2 (front zones) or
and F3 and F4 (rear zones) will appear in the
display. If the fault messages F1, F2, F3, F4, F5,
F6, F8 or F9 should appear in the display
telephone the service department.
The third device protects against a pan on
fire. If you put a pan that is empty or contains
very little on the hob it will measure the
heating process and find that it is heating too
quickly and switch automatically to a lower
power. This lower power will not be visible in
the display. As soon as the plate has reached
the maximum temperature the hob will be
switched off (the second device will have then
come into operation).
