An improved control program for a dishwashing machine which reduces the energy consumption of the dishwashing machine. At the end of a first wash cycle, a portion of the wash liquid, which is at an elevated temperature, is expelled from the tub by operation of a pump. The portion of heated liquid expelled has entrained therein soil filtered from the wash liquid during the wash cycle. An amount of fresh wash liquid, generally equal to the amount expelled, is added to the dishwasher prior to a second wash cycle. The wash liquid is heated prior to the second wash cycle to return the wash liquid to the elevated temperature. The present invention reduces the liquid consumption of the dishwasher, and the amount of electricity used to heat the liquid as compared to current dishwashers which completely drain following each wash cycle.
