ABSTRACT:
A laundry machine which includes a method for adaptively controlling the flow of water into the laundry machine during the rinse phases of a wash cycle. Water is admitted into the machine through a proportional valve and the flow rate with the valve set at a predetermined degree of opening is calculated. This is compared with a desired flow rate and the degree of opening of the valve is incremented, decremented or left unaltered, depending on whether the calculated flow rate is less than, greater than or substantially the same as the desired flow rate.
