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.
