A dishwasher comprising a tub, a reuse tank, and a controller for implementing a wash cycle in the tub, the controller comprising a clock, the controller operably coupled to a recirculation pump and a drain pump, the controller configured (a) to cause the recirculation pump to supply liquid used during the wash cycle to the reuse tank, (b) to monitor via a clock a period of time that the liquid is within the reuse tank, and (c) when the period of time is greater than a predetermined period of time, (i) to cause a control valve in an outlet conduit to open and allow the liquid to flow from the reuse tank to a sump and (ii) to cause a drain pump to drain the liquid from the sump and out of the dishwasher.

Dishwasher system with a reuse tank

A method of operating a dishwasher includes a tub that at least partially forms a treating chamber and a reuse tank fluidly coupled to the tub for storing liquid from the tub for subsequent reuse in the treating chamber. The method includes supplying liquid from the reuse tank to the tub, sanitizing liquid in the tub by heating the liquid to a sanitizing temperature by operating a heating element located in the tub and maintaining the liquid at or above the sanitizing temperature for a sanitizing time period sufficient to sanitize the liquid, and supplying the liquid in the tub to the reuse tank after sanitizing to sanitize the reuse tank.

A method of operating a dishwasher having a wash tub and a reuse tank for storing liquid for subsequent reuse, wherein the condition of the water in the reuse tank may be monitored and/or acted upon to limit the likelihood of undesired effects associated with the growth of micro-organisms in the liquid.

A dishwasher includes a steam-generating vessel positioned in the wash chamber of the dishwasher's tub. A heating element heats water contained in the vessel to generate steam. The heating element may be embodied as thick-film heating element. The steam-generating vessel may be formed in the dishwasher's tub or embodied as a separate component that is secured to the tub.
