Abstract
A dishwashing machine includes a water circulating circuit with rotating spray arms 6, 7 arranged in a washing tub 3 and supplied with water by a pump provided to recirculate water collecting in a sump 5. The water is heated by a resistance-type electric heating element 11 arranged in a casing 10. Through the surface of the casing, the heating element is in a heat exchange relationship with both the interior of the washing tub and the water collecting in said sump. The casing 10 is provided in the water circulation circuit of the dishwashing machine in a parallel arrangement with respect to the spray arms 6, 7, with an inlet 12 connected to the delivery side 14 of the pump 8, and with an outlet 13 communicating with the interior of the washing tub 3.
