Problem
Fan noise coming
from the
induction hob.
A cooling fan built into your induction hob has
come on to prevent the electronics from
overheating. It may continue to run even after
you’ve turned the induction hob off.
This is normal and needs no action. Do not switch
the power of the induction hob off at the wall while
the fan is running.
Pans does not
become hot
and appears on
the display.
The induction hob cannot detect the pan because
it is not suitable for induction cooking or it is too
small for the cooking zone or it is not properly
centered.
Use the cookware that is suitable for induction
cooking.
See “choosing the right cookware”.
Center the pan and make sure that it’s base
matches the size of the cooking zone.
The induction hob or cooking zone has
turned itself OFF unexpectedly. A tone
and an error code is displayed.
(Typically alternating w/ 1 or 2 digits
in the cooking timer display.)
The induction hob is equipped with a self-diagnostic function. With this test the technician is able to check the function of
several components without disassembling or dismounting the hob from the working surface.
