SAFETY
! WARNING
ELECTRICAL SHOCK HAZARD
Disconnect power before servicing the dishwasher. Replace all panels before operating the dishwasher. Failure to do so can result in death or electrical shock.
WHAT TO DO IF THE DISHWASHER DOOR DOES NOT OPEN
If the door latch assembly is damaged or malfunctions, the dishwasher door may not open. If this occurs, the following procedure will open the dishwasher door and allow repairs to the door latch assembly.
1. Insert an Allen wrench between the countertop and the top of the console in the vicinity of the door latch.

INSTALLATION CONSIDERATIONS
GENERAL CONSIDERATIONS
For complete installation procedures see the “Installation Instructions” in the
literature packet provided with the dishwasher.
A video presentation,
4317280V, is available. This video covers the entire installation process.
Each location will present a different set of challenges that can be anticipated and solved before installation begins.
Check the planned location of the dishwasher.
Easy access to hot water, drain line and electricity.
Convenient access for loading. The dishwasher door should open and close freely.
The opening under the counter should be square and the cabinet fronts should be perpendicu­lar to the floor.
Make sure the cabinet opening is free of intrusions such as braces or utility lines.
Do not install the dishwasher on carpeted floors.
An outside wall behind the dishwasher should be insulated to prevent the water line, inlet valve and drain line from freezing and rupturing.

Additional Considerations
The application of a horizontal pump and filter technology allows for the tub to be designed three inches deeper than current models. This deeper tub and longer door design will impact the instal­lation process because there is less working space available underneath the unit and correct routing and placement of the drain hose, water supply and electrical wiring is critical.
The tub must be level. Reduced water consump­tion of this dishwasher requires that it be installed level and plumb for proper water recirculation back into the sump area during operation.
Do not remove the drain tube from the left side of the tub. If the loop is removed, the dishwasher will not initiate Automatic Purge Filtration. The drain tube also contains a check valve in the L-connector that prevents backflow of water into the dishwasher from the house­hold drain system.

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 varia­tion 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 re­quired 160° F.
The Energy Saver Dry option merely turns off the heat during the drying function of the cycle.

SOIL SENSING
* Resistance and
Wattage
Varies with Temperature
The Soil Sensor (pressure switch) monitors soil concentrations during wash functions and communi­cates 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 elimi­nate the second wash function. The Quick Cleanup cycle is the only cycle in which this occurs.
