Abstract
The present invention relates to a method of controlling an automatic dishwasher having a tub, a lower spray arm and an upper spray arm disposed in the tub, a water circulating system including a pump for selectively supplying the spray arms with water, and a heater having a heating element in the tub. The method establishes at least an operative cycle in which the spray arms are supplied alternately with water to spray the crockery. The operative cycle includes a first phase (t1-t2) in which only the lower spray arm is supplied with water, and a second phase (t3-t4) in which only the upper spray arm is supplied with water. The heating element is only energized when the lower spray arm is being supplied with water.
