Abstract
A method is provided enabling a dishwasher to be operated with variable wash programs, wherein the filter systems of the dishwasher do not become overloaded with protruding wash residues in the rinsing fluid. The method makes it possible to vary the pressure used to convey the rinsing fluid from the circulating pump to the at least one spray device. The advantage thereof is that protruding wash residues in the rinsing liquid can be reduced or flattened in order to prevent the filter systems in the dishwasher from becoming overloaded so that the cleaning effects of the filter system can remain functional.

A method for operating a dishwasher comprising at least one washing container, a circulating pump which conveys washing fluid to at least one spray device for acting upon items to be cleaned, which are located in the washing container, and comprising a wash program at least composed of the partial program steps pre-wash (1), clean (2), intermediate rinse (3), clear rinse (4) and dry (5), the method comprising varying the pressure at which the washing liquid is conveyed from the circulating pump to the at least one spray device in order to remove food residues in small quantities by a pre-determined hydraulic abrasion capacity, e.g. spray pressure and spray quantity and carry them away from the dishwasher, thus ensuring that the filter remains functional in the remainder of the wash program.
A dishwasher comprising at least one washing container, a circulating pump which conveys washing fluid to at least one spray device for acting upon items to be cleaned, which are located in the washing container, and means for executing a wash program at least composed of the partial program steps pre-wash (1), clean (2), intermediate rinse (3), clear rinse (4) and dry (5), the dishwasher being operable to vary the pressure at which the washing liquid is conveyed from the circulating pump to the at least one spray device in order to remove food residues in small quantities by a pre-determined hydraulic abrasion capacity, e.g. spray pressure and spray quantity and carry them away from the dishwasher, thus ensuring that the filter remains functional in the remainder of the wash program.
