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.
