Abstract
A washing process for an automatic dishwashing machine, includes the steps of feeding a predetermined volume of water into the wash tub of the machine, adding a predetermined amount of detergent to the water to form a washing solution, heating the so formed washing solution, and subjecting the articles to be washed to the chemical and a mechanical action of the washing solution. After having reached a predetermined temperature, the washing solution is partially discharged and is replenished with a corresponding quantity of water. The detergent is added in two steps, respectively, before and after the partial discharge of the washing solution.
