burners may distort the base of the pan, causing it
not to adhere correctly.

Safety devices

Pan sensor
Each cooking zone is equipped with a pan sensor
device. The hotplate only emits heat when a pan with
suitable measurements for the cooking zone is placed
on it. If the indicator light is flashing, it may indicate:
• An incompatible pan
• A pan whose diameter is too small
• The pan has been removed from the hotplate.
Residual heat indicators
Each cooking zone is equipped with a residual heat
indicator. This indicator signals which cooking zones
are still at a high temperature. If the power display
shows , the cooking zone is still hot. It is possible,
for example, to keep a dish warm or melt butter or
chocolate. As the cooking zone cools, the power
display will show
cooking zone has cooled sufficiently.
Overheating protection
If the electronic elements overheat, the hob switches
off automatically and
followed by a flashing number. When the temperature
has reached a suitable level, this message disappears
and the hob may be used again.
Safety switch
The appliance has a safety switch which automatically
switches the cooking zones off after they have been
in operation for a certain amount of time at a particular
power level. When the safety switch has been
triggered, the display shows "0".
For example: the right rear hotplate is set to 5 and will
switch off after 5 hours of continuous operation, while
the front left hotplate is set to 2 and will switch off after
8 hours.

• An object (a pan, cutlery, etc.) has been placed on
the control panel for more than 10 seconds.
• Something has been spilt on the control panel.
• A button has been pressed for too long. All of the

switch off.
