Replaced motor assembly. The AppliancePartsPros.com video was very helpful except that my dishwasher was attached to the sides of my cabinets rather than the top since I have granite countertops. Once I figured out how it was attached to the cabinets the rest of the pair was fairly easy. The only exception is that my dishwasher is hardwired into a junction box behind the unit and the power cord was too short to bring the dishwasher all the way forward so I improvised and turned it sideways and set it on its back perpendicular to the cabinet.
