The controlling method for the dish washing machine includes; spraying a washing water mixed with detergent into a tub containing dishes, spraying washing water that is not mixed with detergent into the tub, spraying steam into the tub after the spraying of washing water that is not mixed with the detergent, and reducing the humidity of the tub.

Abstract: A method for controlling a dishwasher includes sequentially performing a first main washing step, a second main washing step, and a third main washing step. The first main washing step includes supplying washing water, which is heated by a sump heater, to a washing chamber. The second main washing step includes selectively performing a steam spraying action for supplying steam to the washing chamber, and performing a water supplying action for supplying washing water to the washing chamber. The third main washing step includes supplying washing water, heated by the sump heater, to the washing chamber.

Abstract: The present invention relates to a dishwasher. A dishwasher includes a washing tub in which dishes are placed, a steam generator that generates steam and a nozzle part in which a flow direction of the steam is diverted at least one time to allow the steam exhausted to the washing tub.

Abstract: A dishwasher is provided which can reduce the discharge of noise produced by the dishwasher, thereby preventing a user from being upset due to the noise and achieving not only a comfortable use environment but also an improvement in productivity. With the dishwasher, it is possible to prevent the noise, caused during operation of the dishwasher, from being discharged from a lower side of a door, by use of a sound-insulation member with a simplified configuration. In the manufacture of the dishwasher, improved assembly productivity can be accomplished.

Abstract: A sump for a dishwasher includes a sump case for collecting washing fluid, a pump housing on the sump case, a filtering assembly provided on an upper portion of the pump housing, and a sealing member disposed around the pump housing. The pump housing is provided with a pump case therein.

Abstract: Provided is an air break, a dishwasher having the air break, and a method of controlling the dishwasher. The dishwasher includes a tub defining a washing chamber, a sump for pumping washing water into the tub, an air break connected to the sump. The sump includes an overflow line, which is formed in the air break and along which the washing water flowing back from the sump flows, and a collecting line for collecting foreign objects contained in the washing water flowing back from the overflow line.

Abstract: A sump for a dishwasher includes a sump case for storing washing fluid, a washing pump assembly including a flow guide to pump out the washing fluid, and a filtering assembly including a flow guide to accumulate foreign particles contained in the washing fluid during the circulation of the washing fluid.
