My WDL 540 is completely dead. I’ve checked the fuse etc and I’m now suspecting the main controller. There are no LEDs lit and its as if there is no power. Any suggesting to narrow down the problem.
Remove the mains plug first then check that you have a circuit between the plug top live and neutral to the mains filter just inside the lid at the back. If you do and there is no sign of burning on the mains filter terminals, then sadly your suspicion is almost certainly correct. 😥
