I am not a repairman but have done a little of everything. I noticed that the machine which should have been agitating was locked into position with drum and agitator moving very slowly at the same time during the wash cycle. I immediately thought that it might be a gearbox issue. I removed the small white splutch assembly and noticed some wear but nothing extra-ordinary that would interfere with washing. The main hub that is belt-driven spun freely when I so-called " shifted the gear on the Actuator. While in the other position the entire assembly, which was quite difficult to turn while lying on its side spun...so I knew the gears were ok I took a toothbrush and cleaned all gear teeth. The next thing in line would be the actuator. I took a chance and ordered. I popped the new one in and recalibrated...turn cycle knob to left...right...right...right...left...right..turned cycle knob so that rinse cycle was lit up ...pushed the start button and ...whamo ...I got my old washing back...trouble is.. I bought another washing machine before the part..(which was very quick in getting here)...arrived. I made extra room in the basement and will use the old machine for my farm clothes. YOU CAN DO IT!
