Checking standard operation noises 

5.8.1 

Problem 

The inductor makes a noise when cooking. 

5.8.2 

Cause 

Induction heating technology is based on the creation of 
electromagnetic fields that cause heat to be generated directly on the 
base of the pot. These fields, depending on the construction of the 
pot, may cause certain noises or vibrations. 

5.8.3 

Solution 

The user should be informed that information about normal operation 
noises can be found at the back of the instruction booklet and is 
included below. 

These noises form part of the induction technology and do not indicate 
a fault. 

5.8.3.1 

Low-pitched buzzing sound coming from the transformer 

This noise occurs when cooking with a high level of power. It is 
caused by the amount of energy being transferred from the hotplate to 
the pot. This noise will disappear or weaken as the level of power is 
decreased. 

5.8.3.2 

A low-pitched whistling sound 

This noise occurs when the pot is empty. This noise will disappear as 
soon as water or food is added to the food. 

5.8.3.3 

Creaking 

This noise occurs with pots that are made of various superimposed 
materials. 
The noise is caused by the vibrations that are created on the joint 
surfaces between the various superimposed materials. 
This noise comes from the pot. The amount and manner of cooking 
the food may vary. 

5.8.3.4 

High-pitched whistling sounds 

These noises are more common with pots made of different 
superimposed materials, as soon as they are put on the cooker at 
high power and in both cooking areas at the same time. These 
whistling noises disappear or reduce as soon as the power is reduced. 

5.8.3.5 

Noise from the fan 

For optimum use of the electronic system, the hotplate must operate 
at a controlled temperature. Therefore, the hotplate is fitted with a fan 
that operates when certain temperature levels are detected via 
different power levels. The fan may also operate under inertia after the 
hotplate has been turned off if the detected temperature is still too 
high.
