RAPID ADVANCE SERVICE FEATURE AND DIAGNOSTICS
CYCLES
Pressing the following option keys in the sequence shown will either start the Diagnostics Cycle or turn
on the Rapid Advance feature for stepping through customer selectable cycles:
HIGH TEMP SCRUB, AIR DRY, HIGH TEMP SCRUB, AIR DRY
Or
SANI RINSE, AIR DRY, SANI RINSE, AIR DRY
(Note: HIGH TEMP SCRUB = POWER SCOUR = HIGH TEMP SCOUR)
(Note: AIR DRY = NO HEAT DRY = ENERGY SAVER DRY)
If the above key sequence is entered after starting a cycle, the Rapid Advance feature is turned on,
which allows the operator to manually advance the currently running cycle, interval by interval, by
pressing the Pots&Pans/Heavy or Anti-Bacterial/Cookware or Start key.
If the above key sequence is entered with the dishwasher in Standby, the Diagnostics Cycle is started.
The Diagnostics Cycle can be rapid-advanced, interval by interval, by pressing the Pots & Pans/Heavy
or Anti-Bacterial/Cookware or Start key.
NOTE: The door must be closed before the Diagnostics cycle will run. Likewise, the door must be
closed after each rapid advance selection of the Pots & Pans/Heavy or Anti-Bacterial/Baked On Cook-
ware key for the control to advance to the next interval of the Diagnostics or currently running cycle.
DIAGNOSTICS CYCLE TIME CHART NOTES
(DIAGNOSTICS CYCLE) NOTE 1 – R/A SENSOR ASSY CHECK
To help detect a defective or disconnected Rinse Aid level sensor, the Rinse Aid Empty LED should
light up in Diagnostics if the Rinse Aid dispenser is empty or the circuit is shorted. If the Rinse Aid
dispenser is full, the LED indicator will not light up during the diagnostic test, except in the first incre-
ment.
(DIAGNOSTICS CYCLE) NOTE 2 – THERMISTOR OPEN/SHORT DETECTION
The Diagnostics Test cycle will illuminate the ‘CLEAN’ LED throughout the operating portion of the
cycle that follows the initial display test interval whenever it detects a “short circuit” or “open circuit” on
the thermistor input.
NOTE: Warm water must be in the dishwasher when performing this test. The highest thermistor
resistance values the control can detect as its open circuit criteria are close to the normal thermistor
resistances at room temperature. Consequently, this indicator is only reliable for “open circuit” detec-
tion if warm water is in the dishwasher.
(DIAGNOSTICS CYCLE) NOTE 3 – STUCK PRESSURE SWITCH DETECTION
The Diagnostics cycle monitors the normally open soil-sensing pressure switch input for a “stuck
closed” condition by aborting wash interval 3 and skipping immediately to drain interval 1 if the control
detects a closed pressure switch.
