More than likely this is a coupler problem. I have found many websites that show diagrams of this washer to fix my own. Lay the washer on it's back and remove the motor assembly by removign the screws that hold the motor retention straps in place. (You may have remove the hoses from the water pump to free the motor sufficient to disengage the coupler). You will see a rubber coupler with 2 three pronged enagement couplers. They frequently break off after prolonged use or overloading the washer. These are readily available at Sears for approx. $15. (buy 2 sets for next time). Pry the 3 pronged couplers off with a screwdriver and push new couplers on. Replace motor to original position, engaging the couplers in the rubber bushing. The first time you learn a lot, the second time it's a 30 minute job that saves you $100-$150.
