Possible cause
No power supply
Fluctuations in the power
supply system
Fault / malfunction

was triggered.
Fluctuations in the power
supply system
Metal abrasion or other
soiling may appear like
scratches.
Unsuitable cookware is
used.
Unsuitable cleaning agents
or utensils are used.
Proposed solutions and comments
Ensure that the appliance is properly connected to an
intact power supply.
Check if the fuse has been triggered and
whether there is a power failure in your home or in the
surrounding area.
Disconnect the appliance from the power supply for
about 20 minutes by pulling the plug or releasing the
fuse, then switch it on again.
Disconnect the appliance from the power supply and
contact a certified electrician or customer service.
Make sure that the cookware does not protrude above
the cooking zone markings in the direction of the indi-
cators to avoid overheating them.
Do not use cookware with a shiny base to avoid overhe-
ating due to reflection effects.
Even fluctuations of 10 volts in the mains supply
can lead to a much longer cooking time.
Glass ceramic is more abrasion resistant than steel.
Abrasion marks caused by this do not represent dama-
ge 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 utensils suitable for glass
surfaces (see cleaning chapter).
