Abstract:
A method for operating a washing machine having a tub with a drum rotatably mounted in the tub and configured to hold a fabric load comprises a pre-wash step; a heating step comprising introducing steam into at least one of the tub and the drum; and a washing step. The pre-wash step comprises recirculating liquid between the tub and the drum; rotating the drum at a first spin speed to distribute the clothing within the drum; and rotating the drum at a second spin speed greater than the first spin speed to draw the liquid through the fabric load.
