Check the draining system for clogs and kinks. First, check the draining hose in back of the washing machine. In Whirlpool models, this hose easily becomes kinked and can block the flow of water. Check the lint filter for clogs. Finally, check the side-check valve, which is located at the tub outlet.
Run the washer through a cycle with nothing in the tub. One of the common symptoms of a jammed Whirlpool motor is a nonrotating tub and a burned smell. The belt that powers the pump produces the smell. When the pump gets jammed, the belt begins to split off, causing friction and the burned smell. If you have these symptoms and find a damaged or broken belt, always replace the pump along with the belt. Otherwise, you will damage a new belt instead of fixing the problem.
Check for objects in the drain tubes and pump. To get to the pump and hoses, manually drain the tub and unscrew the back panel. Detach the hoses with a wrench and feel inside them for debris. If you cannot find anything in the hoses, feel inside the pump inlets and outlets with piers and remove any debris.
