Disclosed herein is a water level sensor. The water level sensor includes a reference electrode comprised of a plurality of electrode plates to detect electric conductivity of water filling a space between the electrode plates of the reference electrode. A measuring electrode is comprised of a plurality of electrode plates, which are extended along a length of a water tub to be longer than the electrode plates of the reference electrode and spaced apart from the electrode plates of the reference electrode to detect electric conductivity of water filling a space between the electrode plates of the measuring electrode.
