Normal operating

noises for the

appliance

Low humming like a

transformer

Quiet whistling

Crackling

High pitched whistle

Fan noise

Induction heating technology is based on the vibration

resistance of certain metals when subjected to

high frequency waves. In some circumstances, these

vibrations can cause a certain degree of noise, such

as the following:

This occurs when cooking at a high power. The cause

of this is the amount of energy which is transmitted

from the hob to the cookware. This noise disappears

or becomes quieter when the power is turned down.

This occurs when the cookware is empty. This noise

disappears when water or food is added to the

cookware.

This noise occurs when cookware is used which

consists of layers of different materials. The noise is

caused by vibrations in the joint faces between the

different layers. This noise is made by the cookware. It

may change depending on the amount and type of

food being cooked.

This noise occurs principally in cookware which

consists of layers of different materials when it is used

at the highest heat setting and on two hotplates next

to each other. This whistling disappears or becomes

quieter when the power is turned down.

The electronics require a controlled temperature in

order to function reliably. The hob is therefore fitted

with a fan which runs at various speeds according to

the temperature detected. The fan may also run on

once the hob has been switched off if the temperature

it detects is still too high.

The noises described are normal and part of the

induction technology and do not indicate a fault.
