ABSTRACT:
The present invention provides a method of controlling a washing course in a washing machine, by which a drive motor for rotating a drum is prevented from being overloaded according to a laundry amount and by which a drum can be smoothly rotated without unnecessary power consumption provided to a motor. In a washing machine having a motor for rotating a drum in a first direction, the present invention includes the steps of driving the motor to rotate the drum at a prescribed angle in the first direction, stopping driving the motor so that the drum is rotated by a gravitational force of a laundry within the drum in a second direction opposite to the first direction, and rotating the drum in the first direction again by driving the motor while the drum is rotated in the first direction switched from the first direction by the gravitational force of the laundry.
