Abstract: A rinse arm system for a warewasher includes a rinse arm (1) rotatable about a rotation axis (D), a locking mechanism (2) connected to the rinse arm (1) such that the locking mechanism (2) is rotatable with respect to the rinse arm (1), and a bushing (3). The locking mechanism (2) is latched in an interlocking manner to the bushing (3) or clamped in a force-fitting manner to the bushing (3) such that the locking mechanism (2) is fixedly connected to the bushing (3) and the rinse arm (1) is rotatable about the rotation axis (D) with respect to the bushing (3).

Abstract: A commercial dishwasher comprising spray nozzles for spraying liquid into a treatment region in the form of a treatment chamber or a treatment zone for treating items to be washed; at least two centrifugal pumps, which are arranged in series hydraulically one behind the other, for conveying liquid from the wash tank to the spray nozzles; a control device for alternatively operating only one centrifugal pump or at least two of the centrifugal pumps which are connected hydraulically one behind the other in series, in order to thus generate different liquid pressures.

Abstract: The invention relates to a dishwasher (100) in the form of a programmable machine for the mechanical basic cleaning of washing stock and to a corresponding method for the cleaning of washing stock. The method according to the invention comprises a cleaning phase, in which a cleaning fluid is sprayed out of a tank (4) in to a treatment chamber (2) through a line system (10) by means of a pump (8) and can flow back from the treatment chamber (2) into the tank (4) by gravity, and a rinsing phase, in which fresh water is sprayed as rinsing fluid in to the treatment chamber (2) through a rinsing-line system (15) by means of a rinsing pump (12) and can flow from the treatment chamber (2) in to the tank (4) by gravity.
