I have a wpse42700a0ww washer. When the machine starts to go into spin cycle, there is a loud clicking sound and the barrel seems to want to agitate, then it stops and the barrel only spins at slow speeds, then sometimes it starts to click again. When this happens it also dims the lights in my house. The tub turns both ways when I check it by hand. Don't know if it is the clutch or the transmission. Any help would be appreciated. Thanks.
