  • Publication number: 20170296030
    Abstract: A dishwasher for treating dishes according to any automatic cycle of operation may comprise a treating chamber having an access opening, a door selectively closing the access opening, and a dispenser for dispensing a treating chemistry into the treating chamber. The dispenser may comprise a treating chemistry compartment defining a cavity with an open face. The dispenser may further comprise a movable element movable within the cavity between retracted and extended positions. An actuator may move the movable element between the retracted and extended positions. When the treating chemistry is placed within the cavity, the movement of the movable element from the retracted to the extended position may expel the treating chemistry from the cavity through the open face.
