ZANUSSI aquacycle 1200 end light flashes 4 times in a cycle?

this is an error code to say the door lock has failed.remove the door lock and see if it has a brown burn mark/heat mark on the plastic outer casing.if it has then the door lock is probably blown but because it has fused i would think it has damaged the main pcb door lock triac as well.common issue on these.if both parts are required its not cheap!
