Answer
¡ Noises may be generated while using the hob depending on the base material of
the cookware. These noises are normal for induction technology. They do not in-
dicate that there is a fault.
¡ A deep humming noise similar to a transformer: Occurs when cooking at a high
power level. This noise disappears or becomes quieter when you reduce the
power level.
¡ A quiet whistling noise: This can be heard when the cookware is empty. This
noise disappears when you add water or food to the cookware.
¡ Crackling: This noise occurs when the cookware is made from different multilayer
materials, or if you use cookware of different sizes and different materials. The
loudness of the noise can vary depending on the quantity of food being cooked
or the cooking method.
¡ Loud whistling noises: These may arise if you are operating two cooking zones
at the same time and at the maximum power level. These whistling noises disap-
pear or become quieter when you reduce the power level.
¡ Fan noises: The hob is equipped with a fan that switches on automatically at high
temperatures. The fan may also continue to run after you have switched the hob
off if the temperature measured is still too high.
