Abstract

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.
