Re: servis m9503
Ask customer if there was a light on display before the trouble started. If there’s power getting through from door lock to light (phase side I presume) try tracing the neutral path both from mains plug and from neutral side of light.
If it’s worth the time and trouble, and that’s rather a big if, I’d get a power module off EMW on sale or return before going back. If you do that though, you need to make sure there are no other issues (motor, heater, lock, pump) before fitting as they won’t refund you if it gets damaged.
