1. A dishwasher comprising:

  • a tub at least partially defining a treating chamber with an open side;

    a cover selectively closing the open side;

    a heat-emitting component warming the surrounding air to create warm air; and

    a closed loop condenser comprising;

    a moist air conduit fluidly coupling a first portion of the treating chamber to a second portion of the treating chamber, and having a moist air inlet fluidly coupled to the first portion, an outlet fluidly coupled to the second portion, and a warm air inlet selectively fluidly coupled to the warm air; and

    a dry air conduit fluidly coupled to ambient air and having a portion in overlying relationship with a portion of the moist air conduit, wherein the overlying portions of the moist air conduit and the dry air conduit form a heat exchanger to cool moist air in the moist air conduit and thereby precipitate moisture from the moist air; and

    a controllable gate selectively opening the warm air inlet of the moist air conduit to effect a supply of the warm air to the moist air conduit, wherein the warm air may be supplied to the treating chamber.
