hotpoint aquaris wt740 no power dead?

washer worked one day next day no power had a guy round whom seemed to think it was the pcb board but didnt really check much and said buy a new one ive got some second hand ones if u want which i declined seems a shame as the washer is only 14 months old and aint had much wear my question is, is this guy spinning me a line to buy a new one or is this the most likely problem a common fault say or is there some thing more simple to check that it could be it could be thanks
