Malfunctions are usually due to small details. Before
calling the Technical Assistance Service, you should
consider the following advice and warnings.
Normal noise while the appliance is
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
