Cleanness and Maintenance
The surface of the induction hob may be easily cleaned in the following way:
Type of
contamination
Light Immerse in hot water and wipe dry
Rings and lime Apply white vinegar to the area, wipe with
scale a soft cloth or use a commercially available
product
Sweetmeat, melted Use a special scraper for ceramic glass to
aluminium or
remove residue (a silicon product is best)
plastics
NB: Disconnect the power supply before cleaning.
Failure Display and Inspection
If any abnormality occurs, the induction hob will automatically go into protective mode and display
one of the following codes:
Failure code
E1 Supply voltage is above the rated voltage.
E2 Supply voltage is below the rated voltage.
E3 High temperature of ceramic plate sensor. (1#)
E4 High temperature of ceramic plate sensor. (2#)
E5 High temperature of IGBT. (1#)
E6 High temperature of IGBT. (2#)
Ceramic plate temperature sensor failure- -short
F3/F6
circuit. (F3 for 1#,F6 for2#)
Ceramic plate temperature sensor failure--open
F4/F7
circuit. (F4 for 1#,F7 for2#)
Ceramic plate temperature sensor failure--invalid. (F5
F5/F8
for 1#,F8 for2#)
Temperature sensor of the IGBT failure, (short
F9/FA

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.
