Abstract
A dishwashing machine includes a water circulation circuit provided with at least one rotating spray arm (6, 7) arranged in a washing tank (3). Water collecting in a sump (5) on the bottom (4) of the tank is supplied to the spray arm through a circulation pump (8). The water is heated up by an electric resistive heating element (11) housed in a casing (10) that is a part of the water circulation circuit (9). The casing (10) is arranged within the washing tank (3) in such a manner that the heating element (11) is in a heat-exchange relationship with the interior of the washing tank and the water collecting in the sump (5) through a surface of the casing.
