ABSTRACT:
A dishwasher using steam to heat cold wash water and to propel the heated wash water through a spray arm mounted in a dish containing compartment for washing dishes for a predetermined time period. A detergent liquid is added to the wash water and the entraining action of the steam in withdrawing wash water from a tank underlying the compartment is also used in withdrawing a volume of detergent from a source of supply and delivering it into the wash water. The steam from a boiler is also used to heat cold rinse water delivered to the tank after the wash water has been drained therefrom and to propel this heated rinse water through the spray arm for rinsing the dishes after a predetermined time period. A sterilizing liquid and a rinse aid are added to the rinse water at the start of the rinsing cycle.
