Maytag front load washer (MAH3000AWW) tries to spin but stops. Took the rear cover off to watch the motor. Tries to spin one way, begins jerking motion with the tub moving around a lot, stops, tries to spin the other way with jerking motion, stops, repeats. I can spin the tub easily by hand and it feels very smooth. Spinning the rear tub pulley is also very smooth. Door lock light comes on and door is locked when it's on.
Needs some ideas on what to check. Video of failure is here:
Note: As I was taking that video the washer began to spin smoothly and hasn't failed again?!? Spins smoothly at low and high speed.
