DOES IT DO THIS ON EVERY WASH OR SOMETIMES? IF SOMETIMES, CHECK LID SWITCH( THERE'S A LITTLE HOLE WHEN YOU OPEN THE LID, ON THE LID SHOULD HAVE A LITTLE PLASTIC PIECE THAT GOES IN THAT HOLE. THE SWITCH IS UNDER, INSIDE THAT HOLE. YOU CAN GET A PEN OR KEY TO SEE IF IT'S BROKEN.)

Bad lid switch

We had the same problem with the same model machine and solved it.

Our machine was a month old and started getting stuck at minute 8, so we arranged service calls through Amana customer service. Long story short, the first three service reps couldn't figure out the problem. Two of them called Amana's in-house tech support line and the Amana techs didn't know what the problem was. The fourth repairman was smarter than his predecessors. He called the Amana in-house tech line, spoke to a rep who didn't know what was wrong, and then called in again. He explained that. based on his experience, some in-house techs knew more than others. That turned out to be the case because on his next call-in to Amana, that rep knew exactly what the problem was and recommended replacing the main computer board module. The repair guy ordered and installed the part. The machine has been working perfectly for a month.

you mean you changed plugs on it
if this is the case then you might have a bad ground in which this is plaeging you

Sounds like the water seal is damaged and the leaking water has damaged the top bearing which is just below the water seal. You will need to have the hub & seal kit replaced.
