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.
Troubleshooting
For zone 1 & 2
Problem
Possible causes
What to do
E1,E2,E7,C1
Temperature sensor failure
E3,E4
Temperature sensor of the IGBT failure.
Please contact the supplier.
EU
The connection between the display
board and the main board is fail
EL,EH
Abnormal supply voltage
Please inspect whether power
supply is normal.
Power on after the power
supply is normal.
C3
Temperature sensor of the ceramic glass
plate Is high
C2
Temperature sensor of the IGBT
Is high
Please restart after the
induction hob cools down.
For zone 3 & 4

EL
Supply voltage is above the rated
voltage.
Please inspect whether power
supply is normal.
Power on after the power supply is
normal.
EH
Supply voltage is below the rated
voltage.
C1, C3
High temperature of ceramic plate
sensor .
Wait for the temperature of
ceramic plate return to
normal.
Touch “ON/OFF” button to restart
unit.
C2
High temperature of IGBT .
（

）
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.
No Auto-Recovery
