Abstract: A dishwasher has a treating chamber for receiving dishes for treatment according to an automatic cycle of operation and a dispensing system for storing and dispensing a treating chemistry to the treating chamber during the cycle of operation. The dishwasher may dispense a treating chemistry when a temperature of a liquid in the treating chamber satisfies a predetermined temperature threshold. The temperature of the liquid may be maintained to satisfy the predetermined temperature threshold for a predetermined period of time based on the treating chemistry.

Abstract: A foreign object protection system for dishwashers is disclosed. The foreign object protection system prevents large objects from damaging other components of a dishwasher.

Abstract: A dish treating appliance for treating dishes according to an automatic cycle of operation and including a tub at least partially defining a treating chamber, multiple sprayers emitting a liquid into the treating chamber, and a diverter valve having a rotatable valve body, which can be rotated to discrete rotational positions to selectively fluidly couple with the multiple sprayers. A rotary drive is located exteriorly of the tub and comprises a housing defining an interior with a liquid leak reservoir, a motor carried by the housing, an output shaft rotationally driven by the motor, extending through the housing and the tub, and operably coupled to the valve body, and a printed circuit board (PCB) located within the housing.

Abstract: A dishwasher includes a tub with an access opening to a treating chamber, a sump, at least one sprayer emitting liquid into the treating chamber, a pump, a conduit fluidly coupling the sump to the pump and the pump to the at least one sprayer, thereby defining a recirculation circuit through which the liquid sprayed into the treating chamber collects in the sump and is pumped back to the at least one sprayer. The dishwasher also includes a filter assembly in the sump for filtering the liquid in the recirculation circuit including a cleaning element.

Abstract: A dishwasher includes a tub having an air outlet, an airflow conduit fluidly coupling the tub air outlet to ambient air, a blower assembly forcing air to flow from the tub and through the tub air outlet into the airflow conduit, a first reservoir associated with the airflow conduit and collecting liquid condensed from the air forced through the airflow conduit, the first reservoir fluidly coupled to the tub for draining the collected liquid into the tub, and a second reservoir associated with the airflow conduit downstream of the first reservoir and collecting liquid condensed from the air prior to the exhaustion of the air to the ambient air, wherein any liquid not collected by the first reservoir is collected by the second reservoir for evaporation.

Abstract: A dish treating appliance includes a tub having an access opening and at least partially defining a dish treating chamber a rotating spray arm having multiple spray nozzles and a first supply conduit fluidly coupled to the multiple spray nozzles, and a manifold supplying liquid to the first and second supply conduits, wherein the supply of liquid from the manifold to the first supply conduits causes liquid to be emitted from the multiple spray nozzles into the treating chamber.

Abstract: A dishwasher includes a filtration system that can be configured in a chopping or filtration only arrangement. A check valve cover attached to an accumulator is inserted into a main intake of a sump and divides the main intake into a fluid recirculation chamber in communication with a recirculation intake port, and a separate fluid draining chamber in communication with a drain port. When a drain pump is actuated, fluid is pulled from the accumulator through the drain port until pressure within the fluid draining chamber drops below the pressure of the sump and a check valve in the check valve cover is forced open, allowing fluid to be channeled out of the fluid recirculation chamber into the fluid draining chamber. Optionally, a fine filter system can replace the convertible filtration system, whereby the main intake is in fluid communication with both the recirculation intake port and the drain port.
