Fixing malfunctions
Malfunctions are generally caused by minor faults. Before
contacting the Technical Assistance Service, make sure you
have read the following recommendations and warnings.
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.
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.
Indicator Malfunction Measure
none The electric power supply has been inter-
rupted.
Use other electrical appliances to check if there has been a power
cut.
The appliance has not been correctly con-
nected following the connection diagram.
Make sure that the appliance has been connected correctly.
Electronic system malfunction. If in the above checks, the malfunction is not resolved, contact the
Technical Assistance Service.

The hotplate has overheated and switched
off to protect its working surface.
Wait until the electronic system has cooled down sufficiently before
switching it back on.
* If the warning persists call the Technical Assistance Service.
Do not place hot pans on the control panel.
