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).

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.

Please note down the error
letters and numbers, switch
the power to the induction hob
off at the wall, and contact a
qualified technician.
Solution
Please inspect whether power supply is
normal.
Power on after the power supply is normal.
Wait for the temperature of ceramic plate
return to normal.
Touch ―ON/OFF‖ button to restart unit.
Wait for the temperature of IGBT return to
normal.
Touch ―ON/OFF‖ button to restart unit.
Check whether the fan runs smoothly;
if not , replace the fan.
Check the connection or replace the
ceramic plate temperature sensor.
Replace the power board.
