Noises
Why I can hear noises while I'm cooking?
Noises may be generated while using the cooktop depending on the base material of the cookware. These
noises are a normal part of induction technology. They do not indicate a problem.
Possible noises:
A low humming noise like the one a transformer makes:
Occurs when cooking at a high heat setting. The noise disappears or becomes quieter when the heat set-
ting is reduced.
Low whistling noise:
Occurs when the cookware is empty. This noise disappears when water or food is added to the cookware.
Crackling:
Occurs when using cookware made from different layers of material or when using cookware of different
sizes and different materials at the same time. The volume of the noise can vary depending on the quantity
of food being cooked or the cooking method.
High-pitched whistling noises:
Can occur when two elements are used on the highest heat setting at the same time. The whistling noises
disappear or become quieter when the heat setting is reduced.
Fan noise:
The cooktop is equipped with a fan that switches on automatically at high temperatures. The fan may con-
tinue to run even after you have switched off the cooktop if the temperature detected is still too high.
Cleaning
How do I clean the cooktop?
Using a special glass-ceramic cleaning agent produces the best results. We advise against using harsh or
abrasive cleaning agents, dishwater detergent (concentrated) or scouring pads.
