how can I fix my daughters washer dryer Zanussi WDA1055W?

Sequence of events-got a message m/c had finished and when she opened the door water flooded out. Told her to empty/clean the filter and got a call back can't shut door now won't lock!!!!! When i got to it I checked the outlet pipes -all clear. Got the door to lock by turning power on and rotating program knob and , got to now what I think is the real problem. selecting any program and m/c will stop at every program stop for 2 secs (approx) gets to end of cycle in less than a minute(wish it had washed the clothes though) can hear the pump start for a sec at the appropriate time and the heater fan spins for 1 sec (don't hear the main motor though!! and the drum does not move at all- belt is on!) what is wrong?? model has no dispaly so no fault code.
