Abstract
An apparatus for detecting an error in the measurement of a water level in a washing machine includes a water level sensor measuring a water level in a washing tub; a water supply and drain device supplying water to the washing tub or discharging water from in the washing tub; and a control unit controlling the water supply and drain device to adjust the water level in the washing tub, and detecting a measurement error of the water level sensor based on a water level change measured by the water level sensor while the water level is adjusted.
