<p>The present invention relates to the drainage control of a dish washer. The dish washer provided by the present invention controls drainage by using a water level electrode without an additional means for controlling a drainage pump or a valve in the dish washer by including: vertical nozzle units (130a, 130b) which form a group of nozzles; a rinsing water tank (150) which supplies rinsing water to a rinsing nozzle (121) by pumping through a rinsing water pump (151); a washing water tank (160) which supplies or drains washing water to a washing chamber by pumping the washing water to a washing water pump (161); a drainage means (200) which discharges water by a control command of a control unit (300); electrodes (310) which input a current water level detection signal in a tank to the control unit (300); the control unit (300) which determines the operation of the drainage means (200) and the on/off state of the electrodes (310); and a display unit (320) which displays whether drainage is operated well or not.</p> |
