Here are some repair / testing tips to verify this is the part you need:
The customer complaint on a Whirlpool washer pump is usually the water won't pump out, the motor just hums, or the washer is leaving a small puddle on the floor. Watch the video below to find out how to get to the pump. If your washer is full of water the first theing you will want to do is get the water out of the tub. The best way to get most of the water out of the tub when you don't have a working pump is to take the drain hose out of the drain pipe, take it lower than the level of the tub, and let it drain into a bucket. If you drain hose is mounted high on the back of the washer you won't be able to get most of the water out, but this is still easier than getting all of the water out from the pump hoses. Now that you've gotten as much water as you can out take the washer apart as shown in the video, take the pump off of the motor, undo the clamp on one of the hoses, and drain the rest of the water out of the tub. Once all of the water is out of the tub you can undo the other clamp from the hose on the pump and check the inside of the pump for anything that might be stopping the blade from turning by manually spinning the blade in the pump with a screwdriver. Sometimes the pump blade will come loose from the shaft inside and eat into the casing of the pump. If this happens you will get water on the floor from the hole that is created in the casing by the blade. If blade in the pump won't turn, or you find an area on the pump that slides onto the shaft of the motor that shows the pump has been leaking, replace the 3363394 pump. If you washer motor is humming and the blade of the pump is spinning freely make. Undo the screws holding the clips on the motor, take the clips off of the motor, and pull the motor away from the transmission. Now that the motor is free you can manually spin the motor coupling mounted on the transmission both ways to verify that the transmission is not locked up or that something is not stopping the tub from spinning. If everything spins freely then you can by-pass the lid switch by putting a jumper wire between the 2 wires in the harness that are not green and start the washer. If the motor hums with nothing attached to it you need to replace the motor.
