I used the parts blowup diagram on PartSelect.com and dissasembled the bottom wash assembly. Carefully examining how the washer arm rotated, I determined that the spray arm support nut had broken. The extended top of it has broken off. This nut, when tightened, allows the spray arm to rotate freely. In trying to diagnose the problem, I had even removed the motor assembly at the very bottom. When I reassembled it, I apparently did not seat the gasket well and did not tighten the bolts well, so when I tested the washer, water leaked out the bottom. So, I had to dissasemble it all again and properly torque the bolts. So, I really created another problem during the diagnosis.
