Abstract:
Disclosed is a method of controlling a washing machine having a tub for containing water, a drum rotatably provided in the tub, at least one nozzle disposed in front of the drum to spray water toward the drum, a washing motor configured to rotate the drum, and a circulation pump configured to circulate water discharged from the tub to the at least one nozzle, the method including: a step (a) of supplying water with detergent into the tub to a first water level; a step (b) of operating the circulation pump at a first speed such that the washing motor is repeatedly accelerated and braked while the circulation pump is operating at the first speed, causing laundry in the drum to be stuck to an inner circumferential surface of the drum in response to the acceleration of the washing motor and causing the laundry to fall from the inner circumferential surface of the drum in response to the deceleration of the washing motor, wherein the first speed is set within a range in which the water discharged from the circulation pump is not allowed to reach the at least one nozzle or, even if the water reaches the at least one nozzle, the sprayed water is not allowed to reach an inner circumferential surface of the drum; a step (c) of supplying water into the tub such that a level of water in the tub rises from the first water level to a second water level; and a step (d) of repeating acceleration and deceleration of the washing motor such that the circulation pump is accelerated in response to the acceleration of the washing moto, and the circulation pump is decelerated in response to the deceleration of the washing motor.
