The induction hob or a
cooking zone has turned
itself off
unexpectedly, a tone
sounds and an error
code is displayed
(typically alternating
with one or two digits in
the cooking timer
display).
Technical fault.
Please note down the error
letters and numbers, switch
the power to the induction hob
off at the wall, and contact a
qualified technician.
8. Failure Display and Inspection
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.
