Fixing malfunctions
Malfunctions are commonly due to small details. Before calling
the Technical Assistance Service, you should consider the
following advice and warnings.

Do not rest hot pans on the control panel.
Normal noise while the appliance is working
Induction heating technology is based on the creation of
electromagnetic fields that generate heat directly at the base of
the pan. Depending on how the pan has been manufactured,
these may produce certain noises or vibrations such as those
described below:
A deep humming sound as in a transformer
This noise is produced when cooking on a high power level. It
is caused by the amount of energy transferred from the hob to
the pan. The noise disappears or becomes faint when the
power level is lowered.
A low whistling sound
This noise is produced when the pan is empty. It disappears
when water or food is added to the pan.
A crackling sound
This noise occurs in pans which are made from different
materials superimposed on one another. It is caused by the
vibrations that occur ajoining surfaces of the different
superimposed materials. The noise comes from the pan. The
amount of food and cooking method can vary.
Solution
Use other electrical appliances to check whether there has been a
power cut.
Check that the appliance has been connected correctly according to
the connection diagram.
If the above checks do not resolve the malfunction, contact the Tech-
nical Assistance Service.
Dry the control panel area or remove the object.
Turn the hob off from the mains. Wait 30 seconds or so and switch it
back on.*
Turn the hob off from the mains. Wait 30 seconds or so and switch it
back on.*
Wait for the electronic system to cool down. Then push any symbol
on the hob.*
The automatic time stop has been activated. Press any symbol on the
control panel. The indicator goes out. The hob may now be switched
back on.
Please contact the local electricity board.
Wait until the electronic system has cooled down sufficiently before
switching the hotplate back on.
A high-pitched whistling sound
This noise is produced mainly in pans made from different
materials superimposed on one another, and it occurs when
such pans are heated at maximum power on two hotplates at
the same time. The whistling disappears or becomes fainter as
soon as the power level is lowered.
Noise from the fan
For proper use of the electronic system, the temperature of the
hob must be controlled. For this purpose, the hob has a fan
that starts working after detecting excess temperatures at
different power levels. The fan may also work due to inertia
after the hob has been switched off, if the temperature detected
is still too high.
The noises described are normal, they are part of induction
heating technology and not a sign of malfunction.
