Abstract:
1. A method for setting the liquid level in an automatic clothes washer comprising a wash tub defining a wash chamber for receiving fabric items and a clothes mover located within the wash chamber and driven by a motor to impart mechanical energy to the fabric items upon contact, the method comprising: A) introducing liquid into the wash chamber; B) moving the clothes mover relative to the wash chamber with the motor and outputting a waveform having ripples for one of the motor current and motor speed; C) repeatedly determining a running average of the amplitude of the ripples for the waveform to define multiple running averages; D) determining from the multiple running averages a degree of engagement between the clothes mover and the fabric items based on the multiple running averages; and E) repeating steps A-D until the degree of engagement is less than a predetermined threshold to thereby set the liquid level.
