Just went thru this and bought a MCU but no fix. When I checked the motor I found that the resistance check on the brushes was three times what it should have been. Then discovered that the stator surface was uneven and causing uneven wear to the brushes. Changed the brushes but it only lasted 6 months before having the same problem. Bought a new washer instead of spending $400.00 for a motor. I did NOT buy a Whirlpool.
