Abstract: Dishwasher appliances configured to receive cleaning agent dispensers are provided. A dishwasher appliance includes a tub that defines a wash chamber for receipt of articles for washing, the tub comprising a plurality of sidewalls. The dishwasher appliance further includes a rack assembly arranged in the wash chamber, and a sump for collecting fluid from the wash chamber. The dishwasher appliance further includes a door movable between a closed position and an open position, the door including an inner wall further defining the wash chamber when the door is in the closed position. The dishwasher appliance further includes a dispenser mounting assembly disposed within the wash chamber, the dispenser mounting assembly configured to receive the cleaning agent dispenser.

Abstract: The capture and reuse of the effluent, or grey water, from the rinse cycle of a washing machine appliance is provided. A determination is made regarding whether fabric softener is present in the effluent. If fabric softener is present, then the effluent can be reused during a rinse cycle of the washing machine so as to avoid undesirable interaction between the fabric softener in the effluent and the detergent of a rinse cycle.

Abstract: The present subject matter provides a method for operating a dishwasher appliance. The method includes finely filtering wash fluid with a fine filtration medium via cross-flow filtration and coarsely filtering wash fluid with a coarse filtration medium via dead-end filtration. The finely filtered wash fluid is directed to a spray assembly of the dishwasher appliance. A related dishwasher appliance is also provided.

Abstract: A dishwasher appliance is provided. The dishwasher appliance includes a first spray assembly and a second spray assembly. A pressure actuated valve is coupled to a supply conduit. The pressure actuated valve selectively permits wash fluid from the supply conduit to flow to the second spray assembly. A related method for operating a dishwasher appliance is also provided.

Abstract: A dishwasher appliance is provided. The dishwasher appliance includes a tub that defines a wash chamber and a rack assembly disposed within the wash chamber. The rack assembly includes a frame, a first tray and a second tray. The first and second trays are removably mounted to the frame. The first tray is sized and configured for supporting a plurality of flatware therein. The second tray is sized and configured for supporting a plurality of cooking utensils therein.

Abstract: A filtering system for a dishwashing appliance is provided that can remove fine particles from the wash and rinse fluids. The system includes a filter cartridge that can be rotated between filter media equipped for removal of different particulate sizes depending upon e.g., the cycle or stage of the cleaning process and/or anticipated particle size. The filter cartridge is positioned upstream from the pump inlet. In certain embodiments, the filter cartridge can be removable for servicing.

Abstract: An electrolytic sanitizer is disclosed for use in a dishwasher holding a salt solution, the dishwasher having a water rinse cycle. A spaced anode and cathode are provided in contact with the salt solution in the dishwasher. A source of current provides a voltage across the anode and cathode to generate chlorine from the salt solution, the chlorine being introduced into the water rinse cycle to sanitize objects in the dishwasher. Related dishwasher designs are also disclosed.

Abstract: A dishwasher includes a tub, a fluid circulation assembly, and a water flow blocking mechanism. The assembly includes a pump, which is in flow communication with a lower spray arm via a water passage and at least one other spray arm via a conduit. The water flow blocking mechanism includes a water flow blocking device, a magnet, and a magnet positioning device. The water flow blocking device is normally positioned in a pocket in the conduit. The magnet positioning device is configured to move the magnet from a first position to a second position. When the magnet is in the first position, the water flow blocking device is maintained in the pocket by magnetic forces from the magnet. When the magnet is in the second position, the water flow blocking device is not retained in the pocket by magnetic forces of the magnet.
