A method for controlling a washing machine, comprising a wash cycle and a rinse cycle and wherein the washing machine comprises a tub and a drum rotatably supported in the tub, the control method comprising: a first water supply step including supplying wash water to the tub while the drum is rotated at a water supply RPM; and a first washing step which starts after the first water supply step is completed, the first washing step including accelerating the rotating drum from the water supply RPM to a first washing RPM for the wash water to form a circulating water current falling from an upper area of both ends of the tub while being circulated along an inner circumferential surface of the tub by the rotational force of the drum; characterized in that the control method further comprises: a second water supply step which is performed once the first washing step is completed, wherein in the second water supply step, additional water supply to the tub is performed while the drum is rotated at the water supply RPM; and a second washing step which is performed once the second water supply step is completed, wherein in the second washing step the drum is accelerated and rotated at a second washing RPM higher than the water supply RPM and lower than the first washing RPM for the wash water of which the amount is increased by the additional water supply to form the circulating water current. a first water supply step including supplying wash water to the tub while the drum is rotated at a water supply RPM; and a first washing step which starts after the first water supply step is completed, the first washing step including accelerating the rotating drum from the water supply RPM to a first washing RPM for the wash water to form a circulating water current falling from an upper area of both ends of the tub while being circulated along an inner circumferential surface of the tub by the rotational force of the drum; characterized in that the control method further comprises: a second water supply step which is performed once the first washing step is completed, wherein in the second water supply step, additional water supply to the tub is performed while the drum is rotated at the water supply RPM; and a second washing step which is performed once the second water supply step is completed, wherein in the second washing step the drum is accelerated and rotated at a second washing RPM higher than the water supply RPM and lower than the first washing RPM for the wash water of which the amount is increased by the additional water supply to form the circulating water current. a second water supply step which is performed once the first washing step is completed, wherein in the second water supply step, additional water supply to the tub is performed while the drum is rotated at the water supply RPM; and a second washing step which is performed once the second water supply step is completed, wherein in the second washing step the drum is accelerated and rotated at a second washing RPM higher than the water supply RPM and lower than the first washing RPM for the wash water of which the amount is increased by the additional water supply to form the circulating water current.
