Abstract
Dishwashers and methods of control for operation of dishwashers are disclosed. The operation of the dishwasher can include a drying cycle which uses a steam generator to supply steam to heat a washing compartment. The steam can evaporate moisture on the dishes in the washing compartment. When a condition of the dishwasher is met, such as a temperature or operation time meeting a preset value, an exhaust fan may exhaust air from inside the washing compartment. The operation of the dishwasher can improve power consumption and dry dishes more efficiently.
