Problem
Potential cause
Solution
The hob cannot be
switched on.
No power.
There may be a power
failure. If not, make sure
the hob is connected to
the power supply and
is switched on. Check
whether a fuse may
be flipped or blown. If
the problem persists,
contact a qualified
technician.
The function buttons do
not respond.
The buttons are blocked. Deactivate the key lock
(see "Deactivating the
key lock" in the chapter
"Operation").
The buttons are difficult
to operate.
A thin film of water is on
the buttons or they are
using the tip of a finger
instead of the ball of
your finger.
Make sure the buttons
are dry and use the ball
of your finger.
The glass is scratched.
You are using cookware
with sharp edges or
an abrasive sponge or
scouring agent was used
for cleaning.
Only use cookware with
flat, clean bottoms. Do
not use any scouring
pads or scouring agents
for cleaning.
Some pans make
cracking or clicking
noises.
Due to their
construction, such
noises can occur with
certain cookware, as the
bases are often made of
different materials that
expand differently when
heated.
This is not a fault, such
noises are normal.
