Could be the induction heater board or a door switch.
Had that once or twice.

You need to perform this procedure to get rid of that code:

B. Procedure
1. Turn OFF the main power switch.
2. Turn main power switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the main power switch, turn it on again more than 10 seconds after and
check if the machine starts correctly.
