When I removed the lower service panel (a nice feature of my Amana, you don't have to remove the whole front!) I could see the belt was severely cracked and there was a lot of black residue in the bottom of the case. I pulled the motor/pump assembly and found that the idler pulley was not rotating very well. Replaced the belt, pulley and thrust washer. Repair was pretty straightforward except that I misrouted the belt on my first attempt and had to pull the assemby out. Toughest part was that I had removed one of the heavy springs that keep the drum assembly balanced, and had a heck of a time getting it back into position. Finally realized I could get some lateral movement out of the drum and I wedged it such that the spring distance was a bit shorter. Didn't have to go to the gym that day! Cleaning all the black stuff up took as much time as the repair, and it would have gone faster had I paid more attention to the belt path when I took it out. I wouldn't have had to take the motor/pump assembly out twice!
