The problem with this design turned out to be water infiltrating the seal, along with sand and residue on the bottom of the tub. Changes in the triple lip seal also included some plugs that are used to plug holes in the bottom of the spin basket. This was done in theory to prevent water from reaching the seal at all. The engineers think that there is a protective bell of air under the agitator, surrounding the seal now that the plugs are in place. They also did away with the large plastic filter disk that Amana used to place under the spin basket that acted as a sand filter.
Failure of this seal was largely due to actual bearing damage from poor design tolerances on the machine base and milk stool assembly. These too were re-designed mid stream. Too little, too late. My advice is to avoid any Maytag top loader with 2 panels on the front, which indicate the Amana platform.
