WASHING MACHINE CONTROL SYSTEM AND METHODS

A washing machine system comprising an outer tub with a basket rotatably supported within the outer tub. The basket receives launderable items and wash water. The washing machine includes a drive motor that rotates the basket during the wash operation, and a balance ring associated with the basket containing counterweights that move within the balance ring to compensate for an imbalanced mass in the basket. The washing machine includes a controller communicating with the motor. The controller sends signals to the motor to rotate the basket at selective rotational speeds, and receives electronic signals indicating the power used to rotate the basket at selective speeds. The controller compensates for the imbalanced mass by preventing the drive motor from rotating the basket at a substantially constant speed between a predetermined minimum resonance speed and a predetermined maximum resonance speed for more than a predetermined maximum dwell time during the wash operation.
