• Make sure that the base of the cookware is
GB
always clean and dry, in order to fully utilise and
extend the life of both the cooking zones and the
cookware.
• Avoid using the same cookware which has been
used on gas burners: the heat concentration on
gas 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
when the 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 0 0 0 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.

Buzzer
This can also indicate several irregularities:
• 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
above situations may cause the buzzer to sound.
Remove the cause of the malfunction to stop the
buzzer. If the cause of the problem is not
removed, the buzzer will keep sounding and the
hob will switch off.
