ABSTRACT:
A movement reversal device is used in a dishwasher. The dishwasher has a washing receptacle and a hydraulic assembly provided with at least two spraying devices impinging upon goods to be washed with a fluid transported via a circulating pump. The transported fluid flows through the movement reversal device that contains at least two outlets for feeding different spraying devices. The outlets are opened or closed by a positioning element such that one or several or all outlets are open or closed one after another and/or continuously. In order to better influence the course of the wash cycle and to obtain an optimal washing effect corresponding to the degree of dirtiness of the goods to be washed, the characteristics of the hydraulic assembly and the characteristics of the circulating pump are simultaneously or alternately changed by the movement reversal device.
