zanussi electrolux aquacycle 1000 f1045w?

It wont spin or drain water fully.I have checked the pump it is running ok.The pipes are all clean to the pump from drum and visa versa.I have checked the belt at the back of the drum to the motor and it is perfect and lined up right.Ihave checked the motor its running ok and the carbon brushes are not worn. I am thinking that the only other thing it could be is the crcuit board behind the switches that controls the programs. Could this be the problem? How much are these circuit boards?
