I purchased a used Maytag MAH3000AWA front load. I replace the red wax motor with the black, and I also replaced the control board. It was burnt ! The door locks and the lights come on, the washer spins and drains, but it washes and rinses very slow. It sounds like it is only flipping back and forth every 10 seconds or so....sounds like it is just dragging. I can also still hear water on the inside when the wash is over!
I too had the same problem in my machine and finally called the Repair men. He said that the bearings in the transmission is wearing out and replaced it for 52 bucks. Its better to call a technician soon in your case.
Wash and Rinse cycle are very slow
