Abstract

A washing machine capable of determining an accurate state of a water supplier during a water supply course includes a tub; a drum rotationally arranged in the tub; a driving motor configured to rotate the drum; a water supplier configured to supply water into the tub; a water level sensor configured to measure a water level in the tub; and a controller configured to control the driving motor to perform a first weight detection course before water supply is started, and control the driving motor to perform a second weight detection course based on the water level in the tub being less than a preset water level when a predetermined time has elapsed after the water supply into the tub is started.
