Maytag MHW5100DW0 runs through the cycle fine but will not go into "High" or "Extra High" spin. When it does spin, it starts out normal (low), then steps up a little in speed (Medium fast) and spins at that speed for about 30 seconds then stops. After it stops, it attempts to spin the clothes 2 more times before ending the cycle leaving the clothes excessively wet. It's almost as if it is sensing an imbalance when there isn't one. I can't find any reference to an imbalance switch in the manual or online. This happens on all cycles that call for high or extra high spin and with or without a load of clothes in the washer. The drum is draining completely and the outflow filter was clean when I took it apart. Door lock light is illuminated and door is physically locked during the entire cycle.
