Unlikely to a pcb problem. So I take it it the machine ORIGINALLY did not spin, though it did pump out, so you changed the motor. Were the motor brushes worn out or was the armature shot, is that the sole reason why you changed the motor?
What you need to do is this: does the drum go around on a wash programme? If your new motor does then other than a broken wire it is not a motor fault. The most common reason for no spin on one of these machines when they get on a bit is a a blockage of yukk in the machine`s are trap: sequence is: the machine typically fills higher than is normal, pumps out as normal ( all being well with the pump filter ) but as the machine has drained the compressed air in the air trap / pressure switch hose cannot excape because of the blockage so the machine thinks it has water in it so it will not spin. You need to turn the power off, remove the lid, and you are looking for a thin hose on the right that goes from the bottom of the machine to a switch called the pressure switch. Remove the hose at the pressure swt end , take a gob of water and shoot that water down through the pipe, any restrictions as you blow = a blockage = your problem. To do the job properly normally means dismantling the removal of the front panel or working on the machine underneath to remove and clean out the air trap physically. Hope this suggestion helps.
