Laundry treatment apparatus and method of controlling the same

A method of controlling a laundry treatment apparatus that includes a tub having a space for containing water, a drum rotatably disposed in the tub, the drum having a space for containing laundry and a drum port provided at an upper wall thereof, a chamber to guide water, an agitator rotatably disposed in the drum to create water flow in the drum and to transfer water to the chamber, and a filter disposed at a level higher than the agitator to filter water introduced into the chamber, the method comprising:

• performing a dewatering operation, after water discharge operation, by rotating the drum only in one of a clockwise direction and a counterclockwise direction to separate water from in the drum;
• performing a first water supply operation for rinsing operation by supplying water to the tub;
• performing a dispersion operation by rotating the agitator to an angle that is less than 360 degrees to disperse laundry in the drum, the dispersion operation to separate laundry from an inner circumferential surface of the drum by the water flow;
• performing a filtering operation by rotating the agitator to an angle of 360 degrees or more at a rotational speed that is higher than a rotational speed of the agitator set for the dispersion operation, to supply water to the chamber, and to filter water through the filter;
• performing a first agitating operation by rotating the agitator to an angle that is less than 360 degrees at a rotational speed that is higher than the rotational speed of the agitator set for the dispersion operation and is lower than the rotational speed of the agitator set for the filtering operation,
• after performing the first agitating operation:
• performing a second water supply operation by supplying water to the tub;
• performing a second agitating operation by rotating the agitator to an angle less than 360 degrees at a rotational speed that is higher than the rotational speed of the agitator set for the dispersion operation and is lower than the rotational speed of the agitator set for the filtering operation;
• performing a water flow creation operation by rotating, in a same direction, the agitator and the drum to an angle of 360 degrees or more to create water flow at a circumferential surface of the tub;
• and
• performing a water discharge operation by discharging water in the tub,
• wherein initiation of performing the dispersion operation occurs during the performing of the first water supply operation.
