Problem Possible causes What to do
The cooktop cannot be
turned on.
No power. Make sure the cooker is
connected to the power supply
and that it is switched on at the
wall. Check whether there is
a power outage in your home
or area. If you’ve checked
everything and the problem
persists, call your Authorised
Service Centre or Customer
Care.
The glass is being
scratched.
Rough-edged cookware.
Unsuitable, abrasive scourer or
cleaning products being used.
Use cookware with flat and
smooth bases. See ‘Choosing
the right cookware’.
See ‘Care and cleaning’.
Some pans make
crackling or clicking
noises.
This may be caused by the
construction of your cookware
(layers of different metals
vibrating differently).
This is normal for induction
cookware and does not indicate
a fault.
The cooktop makes a low
humming noise when
used on a high heat
setting (especially
PowerBoost).
This is caused by the technology
of induction cooking.
This is normal, but the
noise should quieten down
or disappear completely
when you decrease the
heat setting.
Fan noise coming from
the cooktop.
A cooling fan built into
your cooktop has come on
to prevent the electronics
from overheating. It may
continue to run even after
you’ve turned the cooktop
off.
This is normal and needs
no action. Do not switch
the power to the cooktop
off at the wall while the
fan is running.
