Hi there,I was wondering if anyone can help me diagnose a problem that I'm having with my Hotpiont WDL540 washer/dryer, it is instantly tripping the rcd as soon as the door is closed. By then pulling the green plastic strap under the machine to open the door again and resetting the rcd, the machine comes on fine, but as soon as is closed, it instantly trips again. Is the door switch the faulty part? Many thanks in advance, Suben
