1. A method for controlling a laundry treating apparatus that includes a tub to store water, a drum provided in the tub to accommodate laundry, a driving device coupled to the tub to rotate the drum, and a controller to detect drum vibration, the method comprising:
performing a first rotation operation such that the drum rotates at a first speed or slower;
supplying water to the tub;
performing a second rotation operation such that the drum rotates at a second speed or slower and which is faster than the first speed;
draining water stored in the tub to outside of the tub; and
detecting a laundry entangled state by detecting a maximum value or a minimum value of the drum vibration while the drum rotates one turn during the second rotation operation.
