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.
Baked On Cookware
The most aggressive to virtually eliminate bacte-
ria from the dish load. Use this cycle for hard-to-
clean, heavily soiled pots, pans, casseroles and
regular tableware. Initial display time: 99 min.
Heavy
Use this cycle for hard-to-clean, heavily soiled
pots, pans, casseroles and regular tableware.
Initial display time: 97 min.
Normal
Use this cycle for loads with normal amounts of
food soil. (The energy-usage label is based on
this cycle.) Initial display time: 95 min.
Light/China
Use this cycle for china and crystal. This cycle
uses a light wash and gentle dry. During heated
dry, the heating element cycles on and off. Initial
display time: 79 min.
