On my M3025 , during the wash cycle, the lights on th front flicker in time with the drum rotation, & the wash cycle neve r seems to complete.
I have to terminate the wash cycle manually & select a rinse cycle.
The lights still flicker in time with the drum rotation but the rinses do complete & it runs thru to the end of the spin cycle.
Electronics board?(I take it its the one at the top on the side?)
