Cleaning and care

Do not use a steam cleaner to clean the cooktop.
The steam could reach electrical components and cause a short
circuit.

If the cooktop is built in over a self-cleaning oven, the cooktop
should not be used while the self-cleaning process is being carried
out, as this could trigger the overheating protection mechanism on
the cooktop (see relevant section).
