Bosch Washing Machine (Goldsworth Park GU21)

This is a 5 years old Bosch Vario Perfect Serie 6 (WAT2840SGB/69) washing machine. It is mechanically sound but is not working. A local "expert" establishment diagnosed a faulty control card but a change of card is not the problem. I think it is a fairly simple problem but I have neither the time nor inclination to work further on it. Ideal for someone with the time and ability to sort it out.
