Abstract
A dishwashing machine includes a tub having an interior that holds a first liquid and a booster tank that includes a housing and at least one heater disposed within the housing. The booster tank is at least partially disposed within the interior of the tub such that at least a portion of the booster tank is at least partially submerged within the first liquid, whereby the first liquid is heated by the booster tank. A dishwashing machine includes a tub containing a liquid therein and a wash pump assembly that includes a pump housing; an inlet in the pump housing; an outlet in the pump housing; and a pump having a motor that pumps the liquid from the tub through the pump housing via the inlet to a device that sprays the liquid within a dishwasher via the outlet. The liquid is heated by means of a heater which is disposed either in proximity to the inlet, in proximity to the outlet, and/or in the spray device before the liquid is pumped out of the spray device.
