Our washer will not spin. I cleaned the trap and the drain hose as well as the drain. This did not solve the problem. I can hear the motor running and whirring like it is trying to spin the tub. I ran a few more cycles while looking at the washer with the front panel open and finally realized the belt is off the pulley. I took the dryer off the washer, (I had help.) and opened the back panel. All of the suggestions I have read about this suggest to check the bearings, the pulley wobbles. My bro-in-law tightened the nut and put the old band back on, spun the pulley a few times, he says he could see the band getting closer to the tub as that happens. He took the band off and said the pulley started to wobble again. He took the pulley off and says the bearings are fine. -are we missing something? Is there another part that will have to be changed. I have the new belt but do not want to put it together just to be chewed up like the original belt. Any help will be much appreciated. Thank you.
