bosch wff1401 washing machine, programmer ?

when programmer is set it works untill it reaches no.7 on the dial, then trips my electrics, does'nt blow the fuse in the plug......it works if i bypass no.7 but of course this is'nt satisfactory........... do i need a new programmer ? i've never had a washmachine were the programmer has faulted. So need it comfirmed, many thanks
