Detergent Dispenser does not open

It is located within the door assembly, close to the detergent dispenser cup. You will need to gain access to the inside of the door.

The detergent door on this model is operated by a wax motor. It can be tested by using a power cord across the two terminals of the wax motor and plugging it into a 120v outlet. The plunger of the motor should push out in approx 45-60 seconds, opening the lid. Use extreme care if testing it this way. The part number for the wax motor is 902899. You also need to look at the linkage where the motor connects to, making sure everything is intact. If you would rather not fool with the thing, you can always pick up detergent tabs that are just added to the bottom of the tub. Hope this puts you on track.
