Fixing Malfunctions - Bosch NIT5068UC Manual Del Usuario

Noises
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.
You can find more information about cleaning and caring for your cooktop in the section on
