Bosch WFF2001

My Bosch WFF 2001 won't wash But when I switch it on and Press Both the Pr Wash Button and the Start Button the Machine, instead of starting up the wash cycle. instead of doing this the Drum starts to spin as if to spin dry and will continue doing so until the Cycle has Finished I thought at first that it could be the Circuit Board that May be the Problem But I'm Not Sure: There was a Rapid Clicking sound Of which would Click, this would Go on until I switched off the Machine About two Months ago I replaced two New Carbon Brushes on the Motor due to it Not working at all: The Machine has been working Properly until Last week Is there anyone that has had the same Problem and was able to Find the fault and Rectify it If you can help me I would be Grateful: I Hate to Loose such a Good Machine I'm not one for Cold water Fill Machines as they take too long to wash
