2. Check the IH board and IH coil

Hello
Please switch off the machine. While holding down 0+8 buttons please switch on the machine.
When the machine is in TEST MODE, input 400 and press the start button, press the 0 button and then press the enter tab on the display.
Switch off the machine wait 1 minute and then switch on the machine.
If the error code reappears the thermistors and thermo fuses need to be replaced in the fuser section.
I hope this sorts out the machine
Regards
