Abstract
A process for treatment of laundry in a basket rotatably mounted in a tub of a washing machine by actuating a valve to introduce water into the tub from a hot water supply until the tub is partially filled so as to soak the laundry contained in the basket, rotating the basket first at low speed and in alternate directions for a predetermined period of time and then at high speed in a single direction for a predetermined period of time while simultaneously recirculating water from a collector below the basket back into the basket during rotation thereof, and discharging the liquid contained in the basket after rotation of the basket is stopped. The method of the present invention allows preheating of the laundry in the basket, the basket and the tub such that it is not necessary to reheat the washing liquid during a subsequent washing program.
