door lock issues.could be a faulty door interlock or main pcb triac faulty.door lock is the cheaper part to try but sometimes when they fail they take the main control pcb triac down at the same time.its not easy to decide which it is without 1st replacing the door interlock but if after fitting new door interlock it does the same then you know its killed the main pcb
