Abstract: Dishwashers and methods of control for operation of dishwashers are disclosed. The dishwasher may include an upper rack in an upper portion of a washing compartment configured to receive small dishes, such as a cup having a small washing load, and a lower rack in a lower portion of the washing compartment for placing large dishes, such as a dinner bowl having a large washing load. The operation of the dishwasher can include wash and rinse cycles having a plurality of sub-cycles. During the sub-cycles, the upper and lower racks can be selectively sprayed with water and steam can be supplied to the washing compartment based on configured conditions, such as a water temperature or operation time being reached. The operation of the dishwasher can reduce excessive washing of dishes having small washing loads and reduce power consumption of the dishwasher.

Abstract: The present invention relates to a dish washer in which a structure for mounting a drain pump is improved for minimizing residual water, vibration and noise. The dish washer includes a cabinet which forms an exterior of the dish washer, a tub in the cabinet to form a space for washing the dishes, a sump assembly at a lower portion of the cabinet, the sump assembly having a drain chamber for holding washing water to be drained, and a drain pump assembly coupled to a lower side of an outside of the sump assembly so as to be in communication with one side of the drain chamber for draining the washing water from the drain chamber by pumping, wherein the drain pump assembly is mounted tilted upward at a predetermined angle from an inside bottom surface of the cabinet.

Abstract: Dishwashers and methods of control for operation of dishwashers are disclosed. The dishwasher can include one or more racks in a washing compartment for placing used dishes having foreign matter, such as food and drink, and unused dishes having relatively little or no foreign matter and varying washing loads. Operation of the dishwasher can include wash, water drain and supply, and rinse cycles. During the cycles, preheating of a steam generator, water draining and supplying, steam supplying, and water spraying can occur and partially or fully overlap. The dishwasher can reduce excessive washing of dishes having small washing loads and improve power and water consumption.
