A dishwasher and a method for operating a dishwasher reduce the length of a washing cycle in a dishwasher as well as the noise which is generated by the impact of the water therein, without altering the performance of the dishwasher. The washing method for a dishwasher having at least two spray devices includes dividing a significant period of time of a washing program duration into a plurality of different lengths of sub-units of time. Substantially every sub-unit of time is made up of at least two time sections. During a first time section, the washing liquid passes through all of the spray devices and during a second time section, the liquid only passes through the lowermost or the uppermost spray device. A dishwasher having at least two spray devices carries out the washing method.

Dishwasher and method for operating a dishwasher

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.

Dishwasher control for dealing with large amounts of food residues by variable wash programs

A method for operating a dishwasher is provided, in which the dishwasher includes at least one washing container, a re-circulation pump for conveying washing fluid to at least one spray device for acting upon items to be cleaned, which are located in the washing container, a lye pump for pumping away washing liquid from the dishwasher. The method includes executing a wash program at least including partial program steps pre-wash (V, V), clean (R, R), intermediate rinse, clear rinse (K, K) and dry, and operating the re-circulation pump and the lye pump at least temporarily in an alternating manner during at least one of the partial program steps (V, V, R, R, K, K).
