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.
Troubleshooting
1) Failure code occur during customer using & Solution;
Failure code
E1
Supply voltage is above the rated voltage.
E2
Supply voltage is below the rated voltage.
High temperature of ceramic plate sensor .
E3
(1#)
High temperature of ceramic plate sensor .
E4
(2#)
High temperature of IGBT .(1#)
E5
E6
High temperature of IGBT.(2#)
Ceramic plate temperature sensor failure-
F3/F6
-short circuit. (F3 for 1#,F6 for2#)
Ceramic plate temperature sensor
F4/F7
failure--open circuit. (F4 for 1#,F7 for2#)
Ceramic plate temperature sensor
F5/F8
failure—invalid . (F5 for 1#,F8 for2#)
Temperature sensor of the IGBT failure.
F9/FA
(short circuit/open circuit for 1#)
Temperature sensor of the IGBT failure.
FC /FD
(short circuit/open circuit for 2#)
2) Specific Failure & Solution
Failure
The LED does not
come on when unit is
plugged in.
Problem
Auto-Recovery
No Auto-Recovery
Problem
No power supplied.
The accessorial power
board and the display
board connected failure.
21
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.
Solution A
Check to see if plug is
secured tightly in outlet
and that outlet is
working.
Check the connection.
