Jenn-Air JDB890AWQ stopped middle cycle no motor...

The dishwasher has power -- panel lights come on. Can start and it will add water. Won't drain or run. Silence. Doesn't sound like motor to me because there is no hum, just silence. The schematic shows an overload protector on the BU wire to the motor. There is a small square item with two black wires that comes off the connection wires to the motor -- including the blue wire. I don't know if that is the overload protector or if it is attached directly to the motor somewhere... or if I'm looking for the wrong solution.
