Troubleshooting
Failure code Problem Solution
Auto-Recovery
E1
Supply voltage is above the rated
voltage.
There may have been a power surge or issue
with the power supply. Please contact your
electricity supplier.
Power on after the power supply is normal
E2
Supply voltage is below the rated
voltage.
E3
High temperature of ceramic plate
sensor. (1#)
Switch the hob off and allow it to cool down.
When the hob has cooled down, press the
‘on/off’ key to switch it on again. Be careful
not to heat up empty pans for too long, and
do not allow pans to boil dry.
Touch “ON/OFF” button to restart unit.
E4
High temperature of ceramic plate
sensor. (2#)
E5
The induction unit may be getting
too hot. (1#)
Switch the hob off and allow it to cool down.
When the hob has cooled down, press the
‘on/off’ key to switch on again. Start to heat
up a pan of water and listen to hear if the
cooling fan comes on. If the cooling fan does
not come on, or it is noisier than it used to be,
please request a service visit.
Touch “ON/OFF” button to restart unit.
Check whether the fan runs smoothly;
if not , replace the fan.
E6 High temperature of IGBT. (2#)
No Auto-Recovery
Please request a service visit
F3/F6
Ceramic plate temperature sensor
failure- -short circuit. (F3 for 1#, F6
for 2#)
Check the connection or replace the ceramic
plate temperature sensor.
F4/F7
Ceramic plate temperature sensor
failure--open circuit. (F4 for 1#, F7
for 2#)
F5/F8
Ceramic plate temperature sensor
failure—invalid . (F5 for 1#, F8 for
2#)
F9/FA
Temperature sensor of the IGBT
failure. (short circuit/open circuit for
1#)
Replace the power board.
FC /FD
Temperature sensor of the IGBT
failure. (short circuit/open circuit for
2#)
