Some pans or pots
make crackling or
clicking noises.

Malfunction /
Display of an error

Possible cause
Metal abrasion or
other soiling may ap-
pear like scratches.
Unsuitable cookware
is used.
Unsuitable cleaning
agents or utensils are
used.
This may be caused
by the construction of
your cookware.
This can be caused by
induction technology.
An integrated cooling
fan prevents the
electronics from
overheating.
If necessary,
it continues to run
even after the hob is
switched off.
Fluctuations in the
power supply system

Code meaning see
following table
What to do
Glass ceramic is more abrasion
resistant than steel. Abrasion marks
caused by this do not represent
damage and can be removed with an
appropriate cleaning agent.
Use cookware with a clean, even
and smooth bottom (see chapter on
cookware).
Only use cleaning agents and uten-
sils suitable for glass surfaces (see
cleaning chapter).
The metal layers of the cookware
vibrate differently when heated.
This is harmless and normal.
This is normal, but the noise should
quieten down or disappear complete-
ly by reducing the power level.
This is normal and necessary for error-
free operation.Do not disconnect
the appliance from the power supply
while the fan is running.
To avoid functional restrictions,
ensure that the ambient temperature
is appropriate and that there is good
ventilation.
Disconnect the hob from the power
supply for about 20 minutes (switch
off the fuse) and then switch it on
again.
Note down the error code,
disconnect the hob from the power
supply and
contact a certified electrician.
