    Abstract: A method of controlling a washing machine that includes a drum rotatably provided in a tub that receives water, at least one nozzle spraying water into the drum, a washing motor rotating the drum, and a circulation pump circulating water within the washing machine, the method including: controlling a rotation of the drum by operating the washing motor to rotate the drum at a first rotation speed in a first rotation direction, and to maintain a rotation of the drum at the first rotation speed in the first rotation direction so that laundry in the drum maintains contact with an inner circumferential surface of the drum; and controlling a pump speed of the circulation pump by operating a circulation pump motor in the circulation pump to accelerate and decelerate at least once while the washing motor rotates the drum at the first rotation speed in the first rotation direction.

    Abstract: A method of controlling a washing machine that includes a tub, a drum rotatably disposed in the tub, at least one nozzle spraying water into the drum, a washing motor rotating the drum relative to the tub, and a circulation pump circulating water discharged from the tub, the method including: rotating the drum to cause laundry in the drum (i) to be raised with respect to a bottom of the drum and (ii) to fall downwards into the drum while water is supplied to the drum; spraying water through the at least one nozzle while the drum rotates; based on a first water level in the tub, controlling the circulation pump to rotate at a first rotation speed; supplying water to the drum to increase the water in the tub to a second water level; and controlling the circulation pump to rotate at a second rotation speed.

    Abstract: A method of controlling a washing machine. The washing machine includes a tub with an entry hole configured to receive laundry, a drum rotatably disposed in the tub, a ring-shaped gasket disposed along a circumference of the entry hole of the tub, a pump configured to circulate water that is discharged from the tub, and at least one circulation nozzle provided in the gasket and configured to spray the water that is circulated by the pump into the drum. The method includes: supplying water into the tub; rotating the drum; accelerating a pump speed of the pump while the drum rotates; and based on the pump speed of the pump reaching a threshold speed during the acceleration of the pump, opening a spray valve of the washing machine such that water supplied from an external water source is sprayed into the drum through a direct water nozzle.
