This fault could be condensation on the printed cucuit board or a dry soildered joint or loose plug conector on the board or even a faulty board .Did you know that all hoover washers have a full 3 year or 5 year parts guarantee weather you took one out or not at the point of sale some times its cheaper to pay a call out charge than it is to buy the parts.Iwould guess that a pc board would be over £80.00 plus fitting etc and Hoover also would guarantee the parts they fit Hope this helps
this is only my opinion and sugestion you could alway phone them and ask .Jim at Arnold domestics 01253 693551
