Abstract: The present invention relates to a method of controlling a washing machine comprising an outer tub containing water, an inner tub which accommodates laundry and is rotatably installed in the outer tub, a dispenser which supplies detergent into the inner tub, and a spray nozzle for spraying water into the inner tub, including the steps of: (a) supplying water into the inner tub via the dispenser; (b) supplying water into the inner tub through the spray nozzle, during when water is supplied into the inner tub via the dispenser; and (c) rotating the inner tub at a cloth wetting speed at which at least some of the laundry in the inner tub is adhered to an inner surface of the inner tub and can be rotated integrally with the inner tub, during when water is supplied through the spray nozzle.

Abstract: A method of controlling a washing machine includes the steps of: (a) processing the laundry by using the water supplied together with detergent; (b) draining the water used in the step (a), rotating the inner tub at a high speed, and operating the pump to drain the water discharged from the laundry; (c) rotating the inner tub at a first speed and supplying the water into the inner tub via the dispenser; (d) stopping the supply of water through the dispenser, rotating the inner tub at a second speed, and supplying the water into the inner tub through the spray nozzle; (e) stopping the supply of water through the spray nozzle and alternately rotating the pulsator at a third speed in both directions; (f) stopping rotation of the pulsator, rotating the inner tub at the second speed for a preset time, and supplying the water into the inner tub through the spray nozzle; (g) decelerating the inner tub from the second speed to a fourth speed, and operating the pump while the inner tub rotates at the fourth speed to drain the outer tub; and (h) accelerating and rotating the inner tub from the fourth speed to dewater the laundry.
