A method of controlling a dishwasher, which heats air in a washing chamber while supplying water into the washing chamber to generate hot water through a heat exchange between the heated air and the supplied water. Further, a second method of controlling a dishwasher operates an air generator while starting of the supplying of water into a washing chamber to heat the supplied water and air in the washing chamber. If a temperature of the water in the washing chamber exceeds a first reference value, the supplying of water is stopped and the air generator is operated.
