Installing Condensate Removal or Direct Vent Options
NOTE
Complete installation instructions are located at the end of this service manual.
The dishwasher may be equipped with either a Condensate Removal Option or a Direct Vent
Option. These options ship separately from the dishwasher in their own containers. Separate
instructions are also included attached to the front of the dishwasher. These instructions may be
requested under the document part numbers listed below:
P/N 115109, Direct Vent Option Installation Instructions
Condensate Removal System Option
The condensate removal system removes dishwasher heat and water vapor at the end of the dishwashing cycle recovering the normally exhausted heat and transferring the recovered heat to the
built-in booster heater which may eliminate the need for a dishwasher vent hood.
Direct Vent System Option
The direct vent system option removes dishwasher heat and water vapor directly into an exhaust
vent which may eliminate the need for a dishwasher vent hood.

switch will go out. The automatic drain valve will open and the machine will drain.
2. The CYCLE light is not illuminated
during the automatic drain cycle.
I
O
3. The drain valve will remain open for 10 minutes to allow time to flush the interior with fresh
water during a cleaning operation.
4. When 10 minutes has elapsed, the drain valve will close.
The automatic drain cycle is complete.
NOTE:
The automatic drain cycle can be repeated after 10 minutes by pushing the power Switch to ON
and immediately to OFF/DRAIN. The dishwasher will drain for another 10 minutes and then
turn off.

Operation
Heavy Duty Wash Cycle Operation
! VERY IMPORTANT !
THE HEAVY DUTY CYCLE MAY BE SELECTED BEFORE OR AFTER THE POWER SWITCH IS PRESSED;
BUT, THE CYCLE SELECTOR SWITCH WILL NOT CHANGE THE CYCLE FROM 4 MINUTES TO 6
MINUTES OR VICE VERSA WHILE THE DISHWASHER IS ALREADY IN CYCLE.
Follow the instructions below to operate the dishwasher in the Heavy Duty Wash Cycle. A Rinse
Sentry feature holds the dishwasher in a wash cycle if the booster heater temperature is below
180ºF/82ºC.
1. Turn the main power on at the main circuit breaker.
2. Make sure the spray arms and the scrap screens are in place.
3. Turn the water supply on.
4. Close the dishwasher hood.
5. Turn the wash cycle selector switch to the desired heavy duty setting of 4 or 6 minutes.

Operation
Rinse Sentry Operation Mode
The final rinse water temperature must be a minimum of 180ºF/82ºC during the final rinse cycle
to ensure all wares are sanitized. If for any reason, the hot water temperature in the booster tank
cannot provide this temperature, the dishwasher will enter a Rinse Sentry Mode of operation and
extend the cycle time.
The Rinse Sentry changes the Standard and Heavy Duty cycle time as described below:
1. The Rinse Sentry constantly monitors the water temperature inside final rinse booster.
2. If the temperature inside the booster heater falls below 180ºF/82ºC, the Rinse Sentry
will extend the wash cycle time until the booster heater water temperature reaches the
proper temperature.
3. The CYCLE light will remain illuminated during the Rinse Sentry Mode.
4. The RINSE water temperature display must be monitored to ensure a minimum of
180ºF/82ºC is maintained during the rinse cycle.
5. The acceptable temperature range for the final rinse water is 180-195ºF/82-91ºC.
6. A wash cycle time of more than 6 minutes may indicate a low incoming water temperature
or a problem with the booster tank operation.
! VERY IMPORTANT !
DO NOT REMOVE WARES UNTIL THE FINAL RINSE CYCLE HAS
SANITIZED THE WARES AND THE GREEN CYCLE LIGHT GOES OUT.
! NOTE !
A wash cycle time of more than 6 minutes may indicate a low incoming water temperature or a
problem with the booster tank operation.

Cleaning and Maintenance
De-liming
Minerals accumulate on the interior surfaces of the dishwasher. The deposits have a white haze
and, in cases of heavy accumulation, may appear as a granular solid. The generic name for
mineral deposits is lime. The removal of lime deposits is called de-liming. Your dishwasher should
be de-limed regularly; how often will depend on the mineral content of your water.
Inspect your machine interior for lime deposits. If de-liming is required, a de-liming agent should
be used for best results in accordance with the chemical supplier's instructions.
! DANGER !
Death or serious injury may result when de-liming solution is mixed with sodium hypochlorite
(chlorine bleach) sanitizing agent. Mixing may cause hazardous gases to form. De-liming solution
and other acids must never be mixed with chlorine, iodine, bromine, or fluorine.
! CAUTION !
Skin contact with de-liming solutions can cause severe irritation and possible chemical burns.
Always wear protective clothing and goggles when handling chemicals.
! VERY IMPORTANT !

Checking Display Set-points
1. The set-point determines the way the semi-circular bar displays temperature. For example,
if the set-point is 70ºF/21ºC, then the bar will indicate yellow beginning at zero up to 70
and change to green from 70 and beyond.
2. There are six set-point values: 70, 120, 150, 160, 165 and 180ºF or 21, 49, 65, 71, 74
and 82ºC depending on the position of the ºF/ºC unit selector switch.
3. Locate the CHECK button on the rear of the display board. It is located in the top center
of the board.
4. Push and hold the CHECK button while observing the front of the display board. The
wash display flashes its current set-point while the rinse display is blank.
5. Release the CHECK button and both displays indicate actual temperatures.
6. Push and Hold the CHECK button, the wash display flashes its set-point and the rinse is
blank. Continue to hold the CHECK button and the wash display blanks out and the rinse
display flashes its set-point.
7. Release the CHECK button and the displays indicate actual temperatures.
Changing Display Set-points
1. Push and hold the CHECK button while observing the front of the display board.
As soon as the wash display flashes its current set-point, (70 in the example below),
immediately release the CHECK button when 70 flashes; push the CHECK button
again— 120 is displayed.
2. Push and release the CHECK button again and 150 is displayed. Push and release
advances the set-point displayed from 70-180.
3. If the desired set-point is 150 and the current set-point is 70, then you would push and
release the CHECK button two times until 150 is displayed.
4. When 150 is displayed hold the CHECK button. 150 will flash indicating that the new
set-point value of 150 is set.
70
5. If you go past the desired set-point, then start over. There is a certain amount of timing
and coordination between pushing the CHECK button and observing the display for the
desired set-point. Repeat steps 1-5 until the desired set-point is entered.

9. The set-points for both displays are now complete.
Verifying the Alphanumeric Display
! ATTENTION !
The Temperature Display Board does not control the operation of the wash tank heater
nor the booster tank heater.
The following procedure only verifies that the alphanumeric display is operating within the
design parameters of the circuit board; it does not calibrate the circuit board.
1. Turn the dishwasher power off.
2. Disconnect power to the machine at the main disconnect switch.
3. Remove the front panel and position it to the left as shown in the photo on page 53 so
the back of the display is accessible.
4. Disconnect the thermistor cable located at the top center of the display board.
5. Disconnect one wire from the rinse switch connector; it does not matter which one.
6. Push the dishwasher power switch UP to the ON position. The machine will fill.
"EEE" indicates the thermistor plug was not
disconnected before verification procedure.
