Have this w/pool washer that starts to distribute clothes ok and then attempts to go into spin far too quickly(without ramping up slowly)It then aborts and service light comes on.I know this is tacho related.Have checked tacho and it seems to be ok (slight voltage when drum is spun).Wiring seems to be fine too.Is this likely to be a motor triac fault on board.Was going to try new tacho but cant locate part no.serv no is 859234715600.
