Abstract | The present invention relates to a method for controlling a laundry treatment apparatus, to reduce a frequency of water hammering noise during a process for washing a filter and a heat exchanger. According to the present invention, the laundry treatment apparatus comprises: a drum rotationally disposed in a tub to receive laundry; the heat exchanger exchanging heat between air flow and a refrigerant on a circulation path circulating air discharged from the tub therethrough; the filter filtering the air flow; a first washing device supplying washing water to one from the filter and the heat exchanger; and a second washing device supplying the washing water to the other one from the filter and the heat exchanger. The method comprises: a flow rate measurement step of measuring a flow rate while supplying water into the tub; and a washing step of controlling, based on the flow rate, a first flow path control valve controlling water supply to the first washing device and a second flow path control valve controlling water supply to the second washing device. When the flow rate is less than a preset reference flow rate, the washing step performs a low pressure washing mode of repeating opening/closing of the first flow path control valve for a plurality of times and repeating opening/closing of the second flow path control valve for a plurality of times. When the flow rate is equal to or greater than the preset reference flow rate, the washing step performs a high pressure washing mode of closing the first flow path control valve after the opening of the same for a preset first time and closing the second flow path control valve after the opening of the same for a preset second time.
