User Manual Neff T59TF6TN0/01 N 90 Electric cooktop

The cookware is too small for the hotplate that is switched on or it is not suitable for induction cooking.
Check that the cookware is suitable for induction cooking and that it is placed on the hotplate that best corresponds to its size. You can find information on the type, size and positioning of cookware in the sections on ~ "Induction cooking", ~ "Flex Zone" and ~ "Move
function".

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 on cleaning and caring for your hob in the section on ~ "Cleaning"

Noises may be generated while using the hob depending on the base material of the cookware. These noises are a normal part of induction technology. They do not indicate a defect.
