Abstract: A structure for blocking outflow of a fluid for a washing machine includes a door installed at an outlet of a detergent supply unit such that the door opens the outlet when wash water and detergent are supplied from the detergent supply unit to a washing tub and closes the outlet of the detergent supply unit when foam or steam is discharged from the washing tub to the detergent supply unit, thereby preventing the fluid, such as foam or steam in the washing tub, from flowing to the detergent supply unit through a water supply bellows.

Abstract: A system and method for controlling a hot water wash cycle in a washing machine is provided. The method includes supplying water to the washing machine, and determining a water level in the washing machine. When the water level reaches a heating water level at which a heating unit is submerged, the heating unit is turned on to heat the water while water continues to be supplied to the washing machine. When the water level reaches a washing water level and the water in the washing machine is at a washing water temperature, the heating unit is turned off and a wash cycle associated with a selected washing condition may be initiated. By turning on the heating unit as soon as it is submerged, wash time may be reduced.
