Abstract:
1. A method for determining a size of a fabric load in a washing machine comprising a wash tub, an agitator for agitating a fabric load in the tub, and a pressure sensor for sensing a level of water in the tub, the method comprising: determining a volume of water supplied to the tub to reach a first level in the tub; determining whether the determined volume of water is indicative of a first qualitative load size; determining a first qualitative load size when the determined volume of water is indicative of the first qualitative load size; and determining a second qualitative load size of the fabric load based on a variation in an output of the pressure sensor during agitation of the fabric load with water in the tub at a level less than an operational water level for the second qualitative load size when the volume of water supplied is not indicative of the first qualitative load size.
