Electrolux oven EOC68000x

My wife set it to self clean but hung a tea towel over handle It got silly hot cut out . The control board fits on 4 pegs to top they melted and the board fell down when you turn it back on at main switch and put it on it stays on as thou it is heating up but goes off after one minute with fault f8 which is the board it also seems the door lock is on how reliable are these codes thank you.
