More specifically, wash water is injected into a washing tub, in which the dishes are held, at a high pressure in the dishwasher and the injected wash water is configured to contact with the dishes so as to remove food scraps from surfaces of the dishes.
- Such the dishwasher is capable of filtering the food scraps or contaminants contained in the wash water by using a filter and re-using the filtered water. Also, detergent is dissolved in the wash water and supplied mixedly together with the detergent, to smoothly the food scraps.
- dishwashers of which a motor raises the temperature of the wash water or generates steam to enhance efficiency of washing performance are broadly used.
- Such the conventional dishwasher includes a case defining an external appearance; a washing tub provided in the cabinet and defining a washing space for the dishes; a door coupled to a front of the washing tub to open and close the washing tub; a sump provided under the washing tub and configured to supply, collect, circulate and drain wash water for washing the dishes; lower and upper arms for injecting the wash water supplied by the sump to the dishes; and lower and upper racks slidingly provided in the tub and selectively disposed according to the kinds and sizes of the dishes.

- wash water For the washing of the dishes, wash water has to be supplied and drained.
- the supplied wash water is guided into the sump and supplied to the lower and upper arms by an auxiliary pump.
- the wash water having been used in the washing is drained outside the dishwasher by a drainage pump.
- the drainage pump is typically located below the sump and the wash water is sucked into a drainage space defined in the drainage pump, as wash water is supplied.
- the air remaining in the drainage space has to be exhausted via a drainage pipe as the wash water is drawn into the drainage space. Because of differences between the drainage pipe and the drainage space in the height and the pressure, the air might fail to be exhausted.
- an auxiliary air outlet hole may be provided in the drainage space to exhaust the air remaining in the drainage space.
- Such an air outlet hole might be blocked by the contaminants drained together with the wash water during the wash water drainage.

- the control unit may determine whether a water level of the wash water after the water supply step (S110) starts is located between the height (H1) to the upper end of the outlet hole 146 and the height (H2) to the upper end of the outlet pipe 162.
- the determination of the wash water level may be performed based on the accumulation of the supplied wash water amount.
- a water flow sensor provided in the water supply unit determines whether the wash water level in the drainage chamber 161 is located between the height (H1) to the upper end of the outlet hole 146 and the height (H2) to the upper end of the outlet pipe 162.
- control unit operates the motor 168 intermittently to exhaust the air remaining in the drainage chamber 161 via the outlet pipe 162 (S220).
- the motor 168 is rotated in the same direction as the wash water is drained.
- the impeller 166 is rotated along the rotation of the motor 168 and the wash water together with air inside the drainage chamber 161 is exhausted along the rotation of the impeller 166.
- the rotation of the motor 168 is performed intermittently.
- the intermittent rotation is performed approximately for 1 ⁇ 2 sec. and then paused approximately for 1.5 ⁇ 2.5 sec. and the intermittent rotation is repeatedly operated two through four times.
- the wash water is fluctuated in the drainage chamber 161 and partially drained together with air by the intermittent rotation at the same time, so that the air pocket formed in the drainage chamber 161 may minimized.
