Abstract
A method and control for an automatic washer is provided in which moisture extraction from a fabric load is controlled by extracting the moisture at increasingly faster levels of basket rotation. Initially the basket is rotated relatively slowly and it is subsequently rotated at successively faster speed levels, each increase occurring after substantially all of the moisture has been removed which is removable at a given speed level. Inertia of the fabric load is measured to determine the amount of incremental moisture removal. Use of such a method substantially reduces the force applied to the fabric load during the centrifugal extraction resulting in less wrinkling of the fabrics.
