A dishwasher includes a housing, a wash chamber in the housing that receives kitchenware therein, a detergent dispenser for introducing a detergent into the wash chamber, and a heater for raising temperature in the wash chamber. The dishwasher further includes a controller for selectively controlling water supply to and from the dish chamber. The controller establishes a temperature of the wash fluid circulating in the wash chamber during the first period in a range from about 115° F. (46° C.) to about 135° F. (58° C.) to enhance the wash performance of enzyme-based detergents and establishes a temperature of the wash fluid during a second period in the range from about 150° F. (65° C.) to about 160° F. (72° C.) to enhance wash performance of a chlorine-based detergent. A method of washing kitchenware contained in the dishwasher comprises (i) removing loose soil on the kitchenware in at least one pre-wash cycle, (ii) washing the kitchenware in a main wash cycle, and (iii) rinsing the kitchenware in at least one rinse cycle. The main wash cycle comprises the actions of (i) washing the kitchenware in a first temperature range for enzyme-based detergent for a first period and (ii) washing the kitchenware in a second temperature range for chlorine-based detergent for a second period.
