Hi. I have a GE spacemaker laundry combo model # WSM2700DAWWW. Normal wash cycle and rinse cycle work properly. Spin cycle does absolutely nothing. The timer turns to spin and it just shuts off. Checked lid switch. Working properly. Took pump apart and no obstructions. Took drain hoses off and no obstructions. What could cause it not to run spin cycle. Do not hear any noise coming from pump or motor or timer. Any ideas??
