Troubleshooting
Problem
Scratches on the
glass surface
Some pans or pots
make crackling or
clicking noises.
A slight humming
noise can be heard
when operating at high
power.
Fan noise
Malfunction /
Display of an error
code
Possible cause
Metal abrasion or
other soiling may ap-
pear like scratches.
Unsuitable cookwa-
re 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 tech-
nology.
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

What to do
Glass ceramic is more abrasion resis-
tant 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 cook-
ware).
Only use cleaning agents and utensils
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 completely
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.
