Cycles
Auto Hot Start:
Auto Hot Start is initiated by the control board when it senses water temperature is below 80°F. If the water
is below 80°F after prewash, the unit circulates for 1 to 5 minutes (depending on the cycle selected) and then
drains for 75 seconds. This procedure repeats up to 4 times or until the water reaches 80°F.
Added Heat:
The added heat option differs for the various cycles. Some cycles will not be modifi ed, some cycles will
increase the calrod time, and some cycles will get additional segments added (e.g., AUTO has 6 segments
without added heat and 9 segments with added heat).
Heated Dry:
During HEATED DRY, the heater cycles at a rate of 60 seconds on and 51 seconds off.
Cycle Explanations and Exceptions:
• Turbidity Response is used during the SANITIZED, NORMAL, and AUTO cycles only.
• Timed cycles can change depending on the water temperature. If the minimum temperature is not met,
an extended time is added until the temperature is met or the time expires.
• Partial Drain and Fill Algorithm is used during NORMAL and AUTO cycles only.
• Auto Hot Start may cause the fi rst prewash to repeat up to 4 times.
• Disabling STEAM will shorten the cycle time.
• If STEAM is selected during NORMAL or AUTO cycles, turbidity response is ignored, and cycle defaults to
the heavy soil algorithm.
• HEATED DRY takes 34 minutes for the NORMAL cycle while the other cycles vary to as long as 60
minutes for PLASTICS. There is no HEATED DRY for the RINSE cycle.
• Drain Overlap is a short period when both the wash and drain pumps run simultaneously as the
circulation cycle ends and draining begins.
• Drain Pause is a short period between the circulation cycle ending and the drain starting.
• Extend Times enables both the circulation pump and heater to operate simultaneously.
Turbidity Response
The turbidity response is measured in DC volts. Four to 5 VDC registers light soil and a shorter wash cycle,
while 0 to 2 VDC registers heavy soil and a longer wash cycle. SANITIZED wash measures the turbidity
response during the third prewash cycle and adjusts the time based on these measurements. NORMAL wash
measures the turbidity response during the fi rst prewash and the prewash before the main wash. If a clean
response is measured during the fi rst prewash, the cycle advances directly to the main wash with no drain or fi ll. If a clean response is measured during the prewash before the main wash, the control shortens the active
heater time.

Water Hardness Test and Calibration
Test Water Hardness
The automatic liquid dishwasher detergent
dispenser (SmartDispenseTM) dispenses the optimum
amount of detergent to clean the dishes. The
amount of detergent introduced during each cycle
is based on the soil level of the dishes and the
hardness of the water. Therefore, the correct water
hardness setting is very important for both optimum
cleaning of dishes and detergent usage.
– 17 –
(Continued next page)
Page 18
Prior to its fi rst use, the dishwasher must be
calibrated for water hardness. This process requires
the use of a water hardness test strip (Part #
WD01X10295).
Test water hardness following the instructions on
the test strip package shown above.
1. Press the SELECT CYCLE and DELAY HRS
buttons simultaneously and hold for 3 seconds.
2. The current hardness setting is shown on the
TIME REMAINING display.
3. Enter the value from the test strip using the
STEAM button to increase the value or the
SELECT CYCLE button to decrease the value.
4. Press the START/RESET button to return the
dishwasher to normal operation. The last
displayed value is saved as the water hardness
value.
The 4 light green stripes on the test strip change
color depending on the water hardness. The harder
the water, the more stripes change from green to
red.
Note: If all stripes remain green after the test, the
outcome is "0 RED." The value to be entered into the
dishwasher is "1."
Convert the test reading according to the table
below.

SmartDispense
TM
SmartDispense is a bulk liquid detergent dispenser
assembly consisting of the following components:
• Detergent Reservoir – Mounted within the inner
door panel.
• Detergent Level Sensor – Connected to a LOW
DETERGENT LED on the control panel.
• Positive Displacement Pump – Injects
the optimal amount of detergent into the
dishwasher during each cycle.
Detergent Reservoir
Note: The SmartDispense system can only be used
with liquid or gel automatic dishwasher detergent.
To access the reservoir, push down on the cap
covering the reservoir to engage the ratchet, then
turn it counterclockwise to open.
To enter water hardness value (on some models):
Note: Dishwasher must be in standby mode. Press
the SELECT CYCLE button to activate the tactile
switch and illuminate the lights on the control panel.

when time
to refill
the reservoir with a liquid automatic dishwasher
detergent until the detergent reaches the threads
of the reservoir access. The dispenser tank holds
approximately 45 ounces of liquid dishwasher
detergent (about 1 to 2 months' supply).
Place the cap on the reservoir access threads, push
down, and then turn clockwise until the cap is tight.
To remove the detergent reservoir:
Note: Removing the reservoir access collar causes
structural damage to the collar. It must be replaced
with a new part (Part # WD35X10059).
Remove the outer door panel. (See Outer Door
Panel.) Insert a small, fl at blade screwdriver into the
slot in the side of the retaining collar and push the
screwdriver handle counterclockwise while turning
the reservoir access collar counterclockwise a
quarter turn. Remove the retaining collar. Unplug the
tube from the reservoir outlet and disconnect the
sensor from the control module.
Detergent Level Sensor
The SmartDispense detergent level sensor consists
of a single-level detection continuity sensor and
includes the following components:
• A grommet seal
• A LOW DETERGENT LED indicator light
• A wire harness
When the detergent in the reservoir drops below
the continuity sensor, a signal is sent to the control
board, and the LOW DETERGENT LED indicator light
is turned on. The light indicates 3 to 7 wash cycles
are left before the detergent reservoir is completely
empty.
Note: The LOW DETERGENT LED may look like it
is illuminated when in fact it is not. An illuminated
indicator shines bright red.
Note: If the SmartDispense system is not being
used, the LOW DETERGENT light can be turned off
(or on) by pressing the ADDED HEAT button 5 times
within 3 seconds. There are 3 audible beeps when
the light goes off.
The sensor is similar to the type used in several
automotive applications, such as the windshield
wiper fl uid reservoir.
Note: The dispenser tank comes as an assembly.
It includes the sensor with wire harness, gasket,
and retaining collar. The complete assembly part
number is WD35X10058.
The control takes a reading of the detergent level at
power-up (when power is restored from an outage)
and each time the door is closed and latched.
The control outputs a pulsing 5-VDC analog signal
to the sensor and monitors the return voltage.
Changes in the quantity of detergent in the tank
change the amount of current drawn by the sensor.
(Continued next page)
– 19 –
Page 20
The routing of the DC wiring from the tank is very
important. The 3 tape points on the tank keep the
DC wiring perpendicular to the AC harness wiring
running down across the front of the tank.
The dispenser pump operates on 120 VAC. During
each prewash cycle, the pump is energized for 5
seconds, dispensing 4 ml of detergent.
The electronic control uses two inputs to determine
the total amount of detergent dispensed during the
main wash cycle:
Tape Point

Sensor and Gasket
Note: The dispenser tank, sensor with wire harness,
and gasket are only available as a complete
assembly (Part # WD35X10058). They are shipped

• Soil level determined by the turbidity sensor
• Water hardness as calibrated for the location
A water hardness selection mode permits the
calibration of the water hardness for the location
at installation. (See
Calibration.)
Water Hardness Test and
To determine the amount of detergent to dispense
during the main wash, the electronic control uses
the following formula:
4 ml x Number of Prewashes
+ 25 ml + Additional Quantity for Hardness
The additional quantity is a predefi ned quantity
of detergent based on the water hardness level
programmed into the control.

Positive Displacement Pump
The SmartDispense positive displacement pump
consists of a continuous fl exible tube running from
the detergent reservoir to the inner door detergent
outlet. The tube runs around the inside edge of the
pump housing. A 3-roller impeller fi ts tightly into
the center of the pump housing, with each of the
3 rollers squeezing the sidewall of the tube. As the
impeller is driven counterclockwise by the motor, it
squeezes out a predetermined amount of detergent
for each 1/3 revolution of the impeller.

Outer Door
2. Remove 2 Phillips-head screws from the lower
right side of the door edge to release the pump
bracket.
A chemical reaction also takes place between the
chlorine detergent and the enzyme detergent,
which causes the two liquids to coagulate and
build up around the detergent level sensor. This
buildup may prohibit the sensor from sending the
low-detergent signal to the control board, and the
LOW DETERGENT light will not illuminate when the
dispenser tank is empty.
Consumer Purge Cycle
The consumer must enter service mode to activate
the purge cycle. (See
Service Mode.) The purge cycle
fi lls the dishwasher for 57 seconds, then energizes
the dispenser pump (instead of the main motor)
continuously to drain the dispenser tank.
The purge cycle deselects all other options and
runs for 65 minutes. The consumer should run the
purge cycle 3 times, fi lling the dispenser tank with
water for the second and third cycles. Total time is
approximately 3 hours.
3. Remove the grommet from the inner door panel
and unplug the tube from the reservoir outlet.
4. Disconnect the wires and remove the pump.

Consumer Purge of the Bulk Dispenser Tank
When to Purge the Bulk Dispenser Tank
Only liquid or gel automatic dishwasher detergent
can be used in the dispenser tank. The dispenser
tank must be purged if the consumer puts hand
dishwashing detergent or a rinse agent in the
dispenser tank. These products produce copious
amounts of suds, and water leaks result every time
the dishwasher is run, until the dispenser tank is
emptied.
The dispenser must also be purged if a liquid
dishwasher detergent containing chlorine (like
Cascade Pure Rinse Formula) and one containing
enzymes (like Cascade Complete) have been mixed
in the dispenser tank. When this happens, the
chlorine destroys the enzymes, resulting in poor
wash performance. You can tell if the detergent
contains chlorine or enzymes by reading the
content label on the container.
To purge the bulk dispenser tank (on some models):
1. Make sure STEAM, ADDED HEAT, and HEATED
DRY LEDs are off.
2. Press HEATED DRY button and SELECT CYCLE
button simultaneously for 3 seconds. If done
correctly, all the LEDs illuminate.
WHITE
3. Press SELECT CYCLE button and ADDED HEAT
button simultaneously for 3 seconds. If done
correctly, the AUTO and LOCK LEDs illuminate.
4. Press START/RESET button one time to exit
service mode.
5. Press START/RESET button to start an auto
cycle and make sure STEAM, ADDED HEAT, and HEATED DRY LEDs are off.
6. Dishwasher runs a complete cycle with the
main motor instead of the dispenser tank. Cycle
is complete when the CLEAN light illuminates.
This should take approximately 60 minutes.
7. Open door and wipe up the excess detergent
from the door and tub.
8. Pour water on the door and tub where there is
detergent residue.
9. Remove SmartDispense cap and fi ll dispenser
tank with water. Replace the cap.

Float Switch
Turbidity Sensor
The fl oat switch activates if water reaches the
fl oat stem inside the dishwasher. The switch only
terminates the voltage to the water valve.
To remove the fl oat swit ch:
1. Remove the two 1/4-in. hex-head screws and
the access panel.
2. Disconnect the fl oat switch wire harness.
3. Remove the 2 Phillips-head screws holding the
switch to the dishwasher.
The turbidity sensor measures the amount of
suspended particles in the wash water in the sump.
The sump water lays within the 1/4- to 3/8-in. gap
between the LED transmitter and the receptor
during the designated fi lls. Successive turbidity
measurements are supplied to the control module
and used to determine whether to add or skip any
prewash or rinse cycles and whether to adjust the
wash or heat times. By measuring the turbidity level,
the control module can conserve energy on lightly
soiled loads by skipping unnecessary cycles. If the
soil level is high, the control module adds one or
more rinse cycles and increases the wash and heat
times as necessary.
Note: If the turbidity sensor fails, the unit operates
for the maximum amount of time, using the
maximum number of wash and rinse fi lls for the
selected cycle.
The turbidity sensor can be tested by checking the
resistance across the wires on the control board at
J3, pin 1 (yellow/black wire), and J3, pin 4 (orange
wire). (See Control Board Connect Locator View.) The
thermistor's resistance has a negative temperature
coeffi cient.
Disconnect
4. Pull the fl oat switch out of the bracket.

Troubleshooting
Service Mode
The dishwasher is programmed with a service mode to aid the technician in troubleshooting it. Each
component can be cycled to detect if it is functioning correctly. Components are cycled by pressing buttons
on the control panel.
To enter the service mode:
• Put the dishwasher in standby mode.
• Press the HEATED DRY and SELECT CYCLE buttons simultaneously.
If performed correctly, the control board responds with two beeps, and all LEDs illuminate for 4 seconds. To
exit the service mode, press the START/RESET button at any time. The dishwasher will automatically exit
service mode if the control panel is inactive for 5 minutes.
Service Mode Control Operation:
When a control is activated in the service mode, the output continues to remain active until the maximum
time has expired or another button is pressed. Once the water valve is activated, the microprocessor must
perform a drain cycle to pump out the water before exiting the service mode.
Control Replacement/Calibration:
The dishwasher enters into the test/00 calibration mode when the unit is fi rst powered on. The door must be
closed and latched. Wait approximately 6 minutes for the second fi ll before canceling the cycle by pressing
the START/RESET button. The dishwasher will be ready to operate after the water is pumped out.

Factory Test Mode
The factory test mode initiates automatically upon installation of a new main control board.
Factory test mode (approximately 5 minutes total):
• All LEDs light (10 seconds).
• Close door.
• Vent opens, fan activates for 5 seconds, and vent closes (15 seconds).
• Detergent rinse module and water inlet valve are energized (45-65 seconds, depending on model).
• Main pump is energized (55 seconds).
• Turbidity sensor is calibrated and other checks occur (90 seconds).
• Drain pump is energized (75 seconds).
• When second fi ll starts, exit test mode by pressing the START/RESET button.
In some cases, it may be necessary to unplug the unit to exit the test mode. If the unit is left in factory test
mode, the dishwasher could run as long as 75 minutes before exiting.
Turbidity Sensor Replacement/Calibration:
When the main control board is replaced, the dishwasher starts a factory test mode when powered on.
During this test, the turbidity sensor is calibrated. If the turbidity sensor is replaced without replacing the
control board, the sensor may be calibrated manually by pressing the START/RESET button 100 times.
If the turbidity sensor fails, the control board uses the maximum wash/rinse cycles.
