OK three things to check -- a. do you have continuity between the door catch and the main pcb ie check the cables. b. are any of the tracks on the pcb blown off & c. Is the door interlock faulty.
Hang on I'll just grab the service manual.
OK F01 indicates that there is a problem with the motor switching Triac which is on the main PCB. But firstly check that the cables and their connectors at each end between the motor and the main pcb are not frayed and tight. Pull them off and then put them back on and recheck and see if you still get the same error.
