1. Wash Cycles Use the arrow pads to scroll through the wash cycles. The light above or next to
the selected pad will be ON to indicate which WASH CYCLE has been selected.
™
NOTE: This dishwasher is equipped with an ExtraClean
Sensor with automatic
temperature control; therefore, cycle length and time may vary depending on
soil (heavy, medium, light) and temperature conditions.
ANTI Heavy 10.0 gallons, 93 minutes
BACTERIAL Medium 8.6 gallons, 90 minutes
Light 7.2 gallons, 90 minutes
This cycle raises the water temperature in the final rinse to sanitize your
dishware. The cycle length will vary depending on the temperature of your inlet
water.
NOTE: The Anti-Bacterial cycle is monitored for sanitization requirements.
If the cycle is interrupted during or after the main wash portion or if the
incoming water temperature is so low that adequate water heating cannot
be achieved, the sanitizing conditions may not be met. In these cases, the
sanitized light will not illuminate at the end of the cycle.

2. DELAY START — This option will allow you to delay the start time of any wash cycle for up to
24 hours (depending on model).
• Select the delay start time you want by pressing the DELAY START pad.
Multiple or continuous pressing will increment the delay hours. Select the
number of hours you want to delay the start of the cycle. Then press
START/RESET.
• After closing the door, the machine will count down and automatically start
at the correct time.
NOTE: To cancel the DELAY START selection before the cycle begins, press
the DELAY START pad until the display is blank. Pressing START/RESET will
not cancel delay hours.
3. ADDED HEAT — When selected, the cycle will run longer with heating elements on to improve
both wash and dry performance.
NOTE: Cannot be selected with RINSE ONLY cycle.
4. PRE WASH — For use with heavily soilded and/or dried-on, baked-on soils. This option
(on some models) MUST be selected PRIOR to starting the cycle. This option adds 16 minutes
to the cycle time.
NOTE: Cannot be selected with RINSE ONLY cycle.
5. HEATED — When selected, turns the drying heater and fan on for fast
DRY drying. This option will extend the cycle time by 30 minutes for
the ANTI-BACTERIAL cycle, 38 minutes for the NORMAL cycle and
COOKWARE cycle, 8 minutes for the SPEED cycle, 15 minutes for the
PLASTICS cycle and 30 minutes for all other cycles. When this is NOT
selected, the fan will turn on to dry your dishes without added heat—and
energy is saved.
NOTE: Cannot be selected with RINSE ONLY cycle.
6. LOCK — You can lock the controls to prevent any selections from being made. Or you
can lock the controls after you have started a cycle.

The Status display tells you what is happening while the dishwasher is in
operation and may flash, indicating a malfunction. The lights will come ON,
indicating the sequence of the dishwasher operation.
SENSING Displayed while the ExtraClean™Sensor is measuring the amount of soil and
temperature of water. The dishwasher will adjust the selected cycle to achieve
optimal performance.
ADD-A-DISH Displayed during prewash indicating that dishes added now will still be
cleaned.
WASHING Displayed during prewash, main wash and rinse periods.
DRYING Displayed during HEATED DRY.
SANITIZED Displayed when cycle has met sanitization conditions.
CLEAN Displayed when a wash cycle is complete and enhancements are complete.
8. Time Remaining Display (on some models)
During operation, the display shows the minutes remaining until the cycle is complete. The
display may adjust the remaining time while the Sensing light is on. During a delay start, the
display will show hours of time remaining until the cycle starts.
9. START/RESET
START — After selecting the cycle and desired enhancements, press the START/RESET
pad to ready the dishwasher to begin the cycle. Close the door to start the
cycle or begin the DELAY START countdown. When the cycle starts, the water
fill begins and approximately 60 seconds later the wash action begins.
The dishwasher will always display your last selection and enhancements. If
you don’t want to change the settings, simply press the START/RESET pad to
ready the dishwasher and close the door to begin the cycle.
NOTE: If the START/RESET light is flashing, the cycle has been
interrupted by pressing the START/RESET pad. Light will quit flashing
after the dishwasher automatically drains out the water.
Also, if a power failure occurs NORMAL and HEATED DRY will automatically
be programmed. Make any new selections and press the START/RESET pad
to begin the new cycle.
RESET — Open the door slowly to prevent splash-out. Press the START/RESET pad
to cancel the cycle and close the door. Dishwasher will pump out and turn off
after 70 seconds.
NOTE: If the START/RESET light is flashing, close the door until the water
pumps out (this takes approximately 70 seconds) and the light stops flashing.
When the light stops flashing, the dishwasher can be reprogrammed and
restarted.
10. Clean — The CLEAN light is illuminated and a double beep will sound when the
selected cycle and enhancements are complete. You may remove the dishes
at any time. Note the high-efficiency fan will run quietly for 30 minutes to 4
hours (depending on selected cycle) after the CLEAN light is illuminated to
continue drying the dishes. This can be interrupted by opening the door and
pressing any keypad.
NOTE: To turn off the double beep indicator (or re-activate it if it was
previously disengaged), press the HEATED DRY pad 5 times within 3
seconds. A triple beep will sound to indicate the end-of-cycle beep option
has been toggled.
