Servis Caress M9090?

I just replaced the pump and it was draining the water for a while, then it stop!!! Now the machine wont go through the wash/rinse cycle and doesn't fill with water. I can here a nosie as through it wants to go through the cycle but it just terminates at the end of the programme without having completed the rinse spin and draining, so the machine is full with water. Had to drain the machine by hand.....What could the problem now be......I'm confused!!!
