My Kenmore 80 Series washer (bought in 2003) won't spin - this happens on an intermittent basis, maybe once a month. When I go to empty the washer, I find all the clothes sopping wet. The pump works during the spin cycle, though, because I can see & hear it pumping the water out. I can get it to spin again if I completely empty the washer. After one or two tries, it will generally start spinning; then I can load the wet clothes back in, start the spin cycle, and it will work. Any ideas on what can be causing this? Thanks! - Katie
