ABSTRACT:
This invention provides a system and method for determining a level of liquid to be supplied for a wash cycle operation in a washing machine given a clothes load and clothes type. The liquid level setting is determined by measuring the time to fill the washer basket and the washer tub with a predetermined initial level of liquid, measuring a change in the level of liquid in the tub and basket after soaking for a predetermined time, and applying a fuzzy logic algorithm to the measured values.
