摘要： Disclosed herein is a washing apparatus includes a drum, a pulsator, a drum drive motor rotates the drum in a first direction or a second direction, a pulsator drive motor rotates the pulsator in the first direction or the second direction, and a controller controls the drum drive motor to rotate the drum in the first direction and to rotate the drum in the second direction when an operation period expires. When a drum drive current value is greater than a first reference current value during the first direction rotation of the drum, the controller controls the drum drive motor so that the drum drive motor stops rotating the drum in the first direction. When the operation period expires the controller controls the drum drive motor so that the drum is rotated in the second direction.
