If you select the Normal Cycle, twice during the cycleyou will hear the wash motor going on and off at amuch different cadence. The pump will pulse severaltimes, repeatedly turning on for less than a secondand off for 10 seconds. This allows it to drive soils off the filter and into the drain while using very littlewater. If, after selecting the Normal Cycle, you select either the Sanitize or Hi-Temp Wash options your dishwasher will understand that a stronger wash is needed and it will not use this pulsing routine
