Abstract

A dishwasher includes at least one adjustable-height basket to which an associated spray arm and its inlet tube are secured. The inlet tube is disposed horizontally and is connected by a coupling to a supply line secured to a side wall of a tub. An open connection fitting and two closed blind fittings protrude toward the inlet tube. The coupling has two openings into which the connecting fitting and one of the blind fittings respectively protrude. In order to provide a simple way of assuring the joining together of the coupling to the fittings, and to assure that pressure losses in the water supply to the spray arm connected to the coupling through the use of the supply and resultant worsening of the cleaning action are effectively avoided, regardless of how the basket is loaded, the coupling has an end oriented toward the supply line with a centering plate and downstream thereof a sealing plate having flexible sealing lips and being freely movable between a housing of the coupling and the centering plate.
