Possible cause
The fuse is blown.

it operated only for a short
time or the sensor is dam‐
aged.
It is normal that there is a
dark area on the multiple

steel and with aluminium or
copper bottoms can cause the
colour change on the glass-
ceramic surface.

Make sure that the fuse is
the cause of the malfunc‐

again and again, contact a
qualified electrician.
If the zone operated suffi‐
ciently long to be hot, speak
to an Authorised Service
Centre.
