CYCLES AND CYCLE VARIATION

The KUD01 dishwasher optimizes washing performance and efficiently uses resources by varying cycle functions and length. The selection of wash options allows the consumer to customize a cycle for optimum washing performance. The soil sensor monitors soils in the wash water and sends input to the electronic control. Generally, if the consumer does not choose a wash option, the electronic control determines which cycle variation should be used.

In models without the soil sensor feature the electronic control automatically uses the Low Soil varia- tion of the cycle unless the customer has chosen the High Temp Scrub option.

Wash Options

•The consumer’s selection of a High Temp Scrub wash option mandates a preset long version of a wash cycle. The exception is the Normal cycle. If very little soils are present the electronic control will use the Low Soil cycle variation with the High Temp Scrub option.

•The Sani Rinse option will mandate a higher final rinse temperature. This does not lengthen a cycle except for the time spent in the thermal hold to raise the water temperature to the re- quired 160° F.

•The Energy Saver Dry option merely turns off the heat during the drying function of the cycle.

Soil Sensing

The Soil Sensor (pressure switch) monitors soil concentrations during wash functions and communi- cates this to the electronic control. If one or more soil sensor trips occur in the first washing interval (interval “42”) of the Pre-Wash Period, the electronic control will use the High Soil version of the cycle. If there are no trips and no options selected, the control uses the light soil version starting at interval

41.Soil sensor trips also invoke Automatic Purge Filtration (APF) events during the Pre-Wash and Wash Periods. See APF description on page 5.

First Fill Water Temperature

The duration of the Quick Cleanup cycle may be modified based upon the water temperature of the first fill. If the thermistor senses water temperature of 135°F or higher, the electronic control will elimi- nate the second wash function. The Quick Cleanup cycle is the only cycle in which this occurs.
