Perform a magnet test, if necessary. If a magnet sticks
to the base of the utensils, they are normally induction
compatible.

X
Pay attention to the cookware bottom. The base of
the cookware should not show any sign of curvature.
Due to incorrect temperature monitoring of the hob
caused by the air gap between the cookware and the
temperature sensor underneath the hob, overheating
may occur. The bottom of the cookware must not have
any sharp grooves or sharp edges to avoid scratching
the cooktop.

Place the cookware (without a mat or similar) directly
onto the glass ceramic.
Noises
The following noises may occur in the cookware when
using induction cooking zones, depending on the material
and the finish of the base:
Q
Q
Humming
may occur when using a high power level. It
decreases or disappears if the power level is decrea-
sed.
Q
Q
Crackling or whistling
may occur due to the bases of
cookware made of different materials (e.g. sandwich
base).
Q
Q
Clicking sounds
may occur during electronic
switching procedures especially at low power levels.
Q
Q
Whirring
may occur when the cooling fan is switched
on. In order to increase the service life of the electronic
system, the cooktop is equipped with a cooling fan.
The cooling fan switches on automatically if the
cooktop is used intensively. You will hear a whirring
sound. The cooling fan may continue running after the
device has been switched off.
5.4 How the cooktop extractor works
5.4.1 power setting
The cooktop extractor has a power-enhancing power
setting.
This power setting makes it possible to suction away high
levels of cooking vapours more quickly. After 10 minutes,
the power setting is automatically switched to power level
9
.
5.4.2 Automatic after-run
The cooktop extractor fans continue to run at level 1 and
switch off automatically after 20 minutes.
