Kenmore 90 Series, M# 100 22922 100. Washer fills and agitates fine, during rinse/spin cycles tub does not spin, water does drain out. If you "help" it by manually turning the tub and starting/stopping it after it starts to spin (it moves slowly), you can here it engage (light clunk) and it will usually spin/rinse fine.

Does not always happen, sometimes complete cycle will process. Other times, no movement during spin-type cycles.

Prior issues with similar washer was failed coupling, coupling is not issue this time, checked. No visible gear lube leaks, no odd noises, no water/fluid leaks. Timers move and go thru entire cycle. This is a washer about 6 years old, but only runs about 4 loads (medium size at that) per week.

Help!!1
