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