I took the machine completely apart last weekend and removed the motor, transmission, and even the tub. Taking that tub out wasn't fun. I had to remove the top of the machine to get to the tub which was not an easy job, but I wanted to make sure nothing was inside the tub to block drainage such as a wash towel. I found nothing inside the tub to slow down drainage so I proceeded to put the tub and outer machine housing back together. I got it together with a lot of cursing. Next I looked at the clutch and noticed some dark black grease caked at the bottom of the clutch housing and inside the clutch shoe rivets. So I cleaned off the clutch housing and clutch shoes with some automotive brake cleaner and put the transmission back in, put the motor back in (which looked like new including the shaft), and then the pump. I filled the machine with water and put it through a cycle and it pumped great! So I think the clutch was slipping while spinning the tub and causing weak drainage. Does this make sense to you pros out there? My wife has done quite a few loads and the machine is now draining 100% every time.
