I have seen some similar posts, but some appear to be for a direct drive, and my washer is a belt drive. The machine will run a cycle normally, and the agitator works fine. However, on the spin cycle, the drum only spins sometimes (and seems to be getting less frequently). I know that the belts are moving and the gears are spinning, so it must be something from the gear up. Could you help me narrow it down? I'd rather not put too much into this machine guessing at possible causes!
