Bosch NITP666UC Manual

Induction technology is based on the creation of 

electromagnetic fields. They may generate heat directly 

on the bottom of the cookware. Pots and pans may 

cause a variety of noises or vibrations depending on the 

way they've been manufactured. These noises are 

described as follows:
Low humming (like a transformer)
This noise is produced when cooking at a high heat 

level. It is based on the amount of energy transferred 

from the cooktop to the cookware. The noise ceases or 

quiets down when the heat level is reduced.
Quiet whistling
This noise is produced when the cooking vessel is 

empty. It ceases once water or food is placed in the 

vessel.
Crackling
This noise occurs with cookware comprised of various 

materials layered one upon the other. It's caused by the 

vibrations of the surfaces where different materials meet. 

The noise occurs on the cookware and can vary 

depending on the amount and method of preparation of 

the food.
Loud whistling
This noise occurs with cookware comprised of different 

materials layered one upon the other, and when they are 

additionally used at maximum output and also on two 

cooking zones. The noise ceases or quiets down when 

the heat level is reduced.
Fan noises
For proper operation of the electronic system, it is 

necessary to regulate the temperature of the cooktop. 

For this purpose, the cooktop is equipped with a cooling 

fan, which is activated to reduce and regulate the 

temperature of the electronic system. The fan may also 

continue to run after the appliance is turned off if the 

detected temperature of the cooktop is still too hot after 

turning it off.
The noises described are a normal element of the 

described induction technology and shouldn't be 

regarded as defects.
