like baldyjoe said, i had this very same prob until minutes ago, I've just moved and i thought the removal guy's had damaged my 4 1/2 yr old machine.
anyway, on the front of my bosch at the bottom right there is a removable circular plastic panel, i took that off and unscrewed the drain-pump cover found inside, a whole load of foul smelling water gushed out and in it was 1 of my wife's chains, which i presume was inhibiting the pump. all is now well and i can cancel the £69 repair fee i was quoted ;)
