i pulled the motor, reinspected the coupling, manually cranked both sides of the motor, manually cranked whatever the coupling attaches to on the back side of the motor (both directions). this moved the agitator which i had not seen before. after reconnecting motor - it worked. hallelujah! something must've been frozen/locked.... we did our first laundry load last nite - it's all good (and i learned a lot about washers).
