<p>The invention relates to a dishwasher having an upper and a lower crockery tray with associated rotatable spray arms, in which the spray arms are fed with washing liquid alternately by a circulating pump, the spray arms being connectable in succession to the output of the circulating pump by means of changeover-valve means in the circulating circuit. If the valve discs of the changeover-valve means are rotatably mounted in the risers on an axis of symmetry perpendicularly to the longitudinal axes of the risers, then they can be switched over by only a low positioning force from the switchover means even while the circulating pump is running. <IMAGE></p> |
