The washer has the following new components:
Drive Motor—The drive motor is an electronically commutated direct drive 3-phase brushless DC design that moves the impeller/agitator and spin basket without the use of a transmission. The motor is comprised of a stator that is bolted to the base of the washer tub and a rotor that is attached to the drive shaft. The motor direction and speed is controlled by the machine/motor controller, and is monitored by a rotor position sensor, (RPS), located on the stator.
The wash basket rides on a hub and rises up with a load of water in it. When it does so, it disconnects from the spin drive hub underneath it. The grinding & stopping could be a failure of the basket to properly stay in position during the wash. If you need to consult the service guide, you may download my copy here
