This accessory is to be used in non-pressurized applications only.
Thermal Expansion—When a water heater is installed in a closed water supply system, such as one having a back-flow preventer in the cold-water supply, means shall be provided to control thermal expansion. Contact the water supplier or local plumbing inspector for information regarding the control of this situation.
Tempering Valve—This water heater is capable of supplying high temperature hot water.
Tempering valves that limit hot water temperature are available for installation in hot water lines. Contact a licensed plumber or plumbing authority.
Temperature and Pressure Relief (T & P)
Valve drain requirements.
CAUTION: To reduce the risk of excessive pressures and temperatures in this water heater, install temperature and pressure protective equipment required by local codes and no less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas
Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22-1986. This valve must be marked with a maximum set pressure not to exceed the marked maximum working pressure of the water heater. Install the valve into an opening provided and marked for this purpose in the water heater, and orient it or provide tubing so that any discharge from the valve exits only within 6 inches above, or at any distance below, the structural floor, and does not contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances.
It is recommended that the drain location be planned before installing the hot water tank.
The T & P valve drain connection faces down.
Locating the drain so that it is directly in line with the connection is recommended.
The T & P valve must be connected to an adequate drain line. A 1/2" male NPT thread is required to connect to the valve.
The valve discharge line must be as follows:
• Must not be smaller than the pipe size of the relief valve or have any reducing coupling installed in the discharge line.
• Must not be capped, blocked, plugged, or contain any valve between the relief valve and the end of the discharge line.

PRODUCT OPERATION
GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
The dishwasher is provided with a Ground
Fault Circuit Interrupter (GFCI). It is a built-in safety feature designed to protect against the dangers of line-to-ground electrical faults. If a fault of this type develops, the GFCI will disconnect the power to the dishwasher. The GFCI should be tested once a month.
To do this test, perform the following steps:
1.
Press the “Test” button. The LED indicator should be “OFF” (not visible in the window).
2.
Press the “Reset” button. The LED indicator should be “ON” (visible in the window).
IMPORTANT: Do not use the dishwasher if the
GFCI test fails. Call the KitchenAid Customer

A pressure switch is used to fill the dishwasher with approximately 3.1 liters or 3/4 gallon per fill. A second switch in the pressure switch protects against an overfill condition.
levels. By keeping the pressure switch tubing higher than the water level in the dishwasher, any suds buildup can drain back into the tank.
The sensing tubing for the pressure switch is routed from the sump air dome to the pressure switch. A protective cover is provided for the pressure switch tubing at the sump to prevent foreign materials from entering the tubing. The tubing is also routed to one of the air gaps and back to the switch, providing protection against suds forming in the tubing and filling it. Should the tubing become filled with suds, the pressure switch would be unable to sense water
Pressure Switch

LID LATCH
A lid latch mechanism holds the dishwasher lid closed during the cycle. A wax motor and trip arm assembly are mounted alongside the lid mechanism to open the lid at the end of the cycle. Once the dishwasher has reached the final rinse, the wax motor is energized for the final two minutes. As the wax motor reaches its full extension, it moves the attached release arm to disengage the lid latch, and allow the lid to pop open. The opening of the lid, coupled with the high water temperatures, causes the dish load to “flash dry,” due to the sudden venting of the heat and steam in the dishwasher. This is the only means of drying. No heating element is provided for drying dishes.
Release Arm Wax Motor
Interlock Switch
INLINE WATER HEATER
An inline water heater is used to heat water during the cleaning cycle. The heater is located between the sump and the wash pump. Water from the sump flows through the heater, into the wash pump inlet, and is then recirculated through the poppet valve into the tank.
OPTIONAL AUXILIARY WATER HEATER
An auxiliary water heater can be installed to boost the water temperature for immediate hot water at the beginning of the cycle. The auxiliary water heater consists of a 2-1/2 gallon tank, and a 1100 Watt heating element. The water heater heats the water to a temperature of 165
°F / 74°C to provide a shorter wash cycle.

WASH SYSTEM
The three-level wash system provides excellent cleaning results. Three levels of filtration filter the wash water, and prevent food particles from redepositing on the clean dishes. The three levels operate as follows:
• A coarse strainer as part of the Drain Stopper assembly (1), prevents bones, pits, and other large objects from entering the pump system.
• Items small enough to pass through the coarse stainer are caught in the Drain Screen
Basket (2).
• The wash water continuously flows through the Drain Fine Screen Filter (3), trapping food particles.
• Two water jets, located under the spray arm, remove the food particles from the Drain
Fine Screen Filter.
NOTE: Before each wash load, check the coarse strainer, the drain screen basket and the drain fine screen filter and remove any objects and soil particles.
DRYING SYSTEM
TM The wash system features FLASHDRY instant drying. At the end of the cycle, the lid automatically pops open, allowing vapor to escape, aiding in fast, efficient, dishload drying.
IMPORTANT: The vapor is hot. Do not touch the lid opening during drying. Do not place anything on top of the lid when running a cycle.

Hot Water Tank Operation
WARNING
Water temperature over 120
°F can cause severe burns instantly or death from scalds.
Children, disabled, and elderly are at highest risk of being scalded.
See instructions manual before setting temperature at water heater.
Feel water before bathing or showering.
Temperature limiting valves are available.
The water supply MUST be turned ON before operating the hot water tank. Operating the hot water tank without the water supply turned on could damage the hot water tank.
NOTE: When the hot water tank is first used, it will take about 45 minutes for the hot water tank to finish heating the tank water to the selected temperature after the first dishwasher cycle is completed. The hot water tank will then continually maintain the temperature set by the
Temp Control switch.
When the hot water tank is first heated, it is normal for a slight amount of water to be discharged into the dishwasher.
To reduce the risk of scald injury, the Temp
Control switch has been factory set to “LOW”
(bottom position) which heats water to 120 °F /
49 °C.
If faster dishwasher cycle time is desired, the
Temp Control switch can be set to “HIGH” (top position) which heats water to 165 °F / 74°C.
The FREEZE PROTECT (center) setting will restart the tank periodically to prevent freezing.
Use this setting if the hot water tank and dishwasher will not be used for an extended period of time.
GROUND FAULT
CONTROL INDICATOR (GFCI)
Test the GFCI once a month (see Steps 9 through 11 on Page 2-14).
If the GFCI will not reset and the outlet is properly grounded and polarized, disconnect the power supply cord, and DO NOT use the
hot water tank.
LOCKOUT CONDITION
If either light blinks, the tank is in a “lockout” condition.
To reset, disconnect the power supply cord for
1 minute, and then reconnect the power.
If this does not correct the “lockout” condition,
DO NOT use the hot water tank.

DIAGNOSIS & TROUBLESHOOTING
DIAGNOSTICS CYCLE TIME CHART
Refer to the chart on the next page.
R/A SENSOR ASSEMBLY CHECK
To help detect a failed or misconnected “Rinse
Aid” level sensor, the control should operate the “Rinse Aid Empty” LED in Diagnostics as it does during any other cycle.
THERMISTOR OPEN/SHORT
DETECTION
The Diagnostics Test Cycle will illuminate the
“CLEAN” LED and “WATER HEATING” LED. It lights 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” detection if warm water is in the dishwasher.
As a means of testing the accuracy of the thermistor circuit, the control will turn on the
“SANITIZED/SANI COMPLETE” LED in “Interval 3” of the Diagnostics when it detects a thermistor resistance of 10 k Ω.
STUCK PRESSURE SWITCH
DETECTION
The Diagnostics Test Cycle will illuminate the
“SENSING/SOAKING” LED throughout the operating portion of the cycle that follows the initial display test interval whenever it detects an “open circuit” on the pressure switch (soil sensor) input. The Diagnostics Cycle also monitors the normally-open soil-sensing pressure switch input for a “stuck open” condition by aborting wash “Interval 3,” and skipping immediately to drain “Interval 1” if the control detects an open pressure switch.
DISPLAY TEST
All LEDs, regardless of function, are turned On during the first interval of the Diagnostics Cycle as a “Display Test.” All LEDs should light, and all segments of any time display should light. If any LED does not turn On, there is an open circuit in the keypad, and the console assembly/keypad should be replaced.
DIAGNOSTICS CYCLES
Pressing the following option keys in the sequence shown will start the Diagnostics Test
Cycle:
RINSE ONLY
SANI RINSE
RINSE ONLY
SANI RINSE
Once Diagnostics Cycle is started, the cycle can be rapid advanced to the next interval manually by pressing the “Start” key, or the
“Pots & Pans” key. NOTE: The door lid must be latched after each key press to advance to the next interval.
RAPID ADVANCE
SERVICE FEATURE
To turn on the “Rapid Advance Service Feature,” start the desired cycle, and then press and hold the “Start” key for 5 seconds. Once
“Rapid Advance” is turned On, the cycle can be rapid advanced manually, one interval at a time, by pressing the “Start” key, or the “Pots &
Pans” key. NOTE: The door lid must be latched after each key press to advance to the next interval.

CHECKING THE KEYPAD AND KEYSWITCH OPERATION
CHECKING KEYPAD OPERATION
Check the keypad ribbon tail for:
• Broken, shorted, corroded, or creased traces.
• Loose connection to the control.
• Contaminants or corrosion around the perimeter of the keypad, on the keypad or the ribbon tail, or the keypad connector at the control.
To test an LED function, confirm that the LED turns On during the “Display Test” at the beginning of the Diagnostics Cycle (refer to the
“Diagnostics Cycle Time Chart” on pages 6-1 and 6-2).
CHECKING THE KEYSWITCH
CONTACTS
Before checking the keyswitches:
• Disconnect power to the dishwasher.
• Unplug the ribbon cable at connector P1 on the control board.
Using the table below, measure the resistance across the switch when the key is pressed.
NOTE: The ohmmeter must be connected with the proper polarity.
If you are using an analog meter, the resistance reading should go from infinity (open circuit) down to a readable resistance level.
The level may be different, depending on your meter, since there is a diode in the circuit.
If you are using a digital meter, the resistance reading should go from infinity (open circuit) down to a readable resistance level.
The level may be different, depending on your meter, since there is a diode in the circuit. If available, you can use the “diode test” function of the meter, which will supply a voltage of about 1.2 VDC during the test.
If any switches fail the test, replace the console panel/keypad assembly.
If all of the switches test okay, replace the control board.

22 are “closed.” Disconnect the harness leads from the pressure switch. If there is an open circuit across 21 & 22, replace pressure switch.
4. Disconnect the harness leads from the water inlet valve and measure the resistance of the valve coil.
5. Instruct the customer on the drain stopper installation, refer to Use and Care
Guide.
6. Disconnect the water line to fill valve and inspect the inlet for obstructions.
7. Check operation of the fill valve by the control during Diagnostics.
8. Customer Instruct - normal water level is just above bottom of tub.
9. Engage drain stopper. Run water into the dishwasher. If water drains out of the dishwasher, replace the stopper.
1. Pump motor seized up (will not turn).
2. Loose harness connection in pump motor circuit.
3. Damaged wash pump motor capacitor.
4. Pump motor winding opened.
5. Faulty wash pump drive circuit on the control.
1. Remove the pump motor housing. Verify the rotation of the motor shaft by rotating the impeller. Rotation should only require a moderate force. If the rotation is difficult or not possible, replace the pump & motor assembly.
2. Check the resistances of all connections between the pump motor and the control, particularly the pump motor to its capacitor.
3. Disconnect the capacitor leads and confirm that the capacitance is as labeled on part. Also check the resistance for an open circuit across the terminals. Replace if open.
4. Disconnect all leads and check the resistance of the windings.
5. Check the operation of the wash pump motor by the control during Diagnostics.

PROBLEM
Unit will not drain or there is excess water left in unit.
The Check Drain LED is flashing.
POSSIBLE CAUSE
1. Obstructed drain hose or drain path.
2. Loose harness connection in drain motor circuit.
3. Open winding on drain pump motor.
4. Drain pump impeller fractured.
5. Drain hose check valve not sealing.
6. Faulty drain motor drive circuit on control.
SOLUTION
1. Check for blockages from the drain pump to sump. Potential items: blocked/ stuck drain pump or drain hose check valve, and/or plugged hoses.
2. Check the resistances of all connections between the drain motor and control.
3. Disconnect the harness connections and check the resistance of the drain motor windings.
4. Remove the drain pump and check the impeller by pulling and rotating it. If the impeller pulls off easily, or turns freely
(normally there is some uneven resistance), it is stripped. Replace the pump.
5. Disconnect the drain hose at the air gap.
Elevate the hose above the dishwasher and fill with water. If water flows into dishwasher, replace the drain hose.
6. Check the operation of the drain motor by the control during Diagnostics.
Poor wash performance.
Film on glasses and/or dishes.
1. Customer cycle selection not appropriate for dish load.
2. Plugged or damaged screens.
3. Spray arms not rotating.
1. Hard water leaving film on dishes.
2. Detergent carryover.
3. Drain hose check valve not sealing.
1. Instruct the customer on the cycle selection.
2. Inspect following 3 screens. Remove the dish rack and inspect the fine filter screen. Remove the coarse filter and the drain screen basket. Clean or replace as needed.
3. Check for free and proper arm rotation by operating the dishwasher and opening the lid to check that the location of the arms are not always in the same place. If the arms are blocked, instruct customer on stacking dishes. May also have restricted flow/movement due to misalignment or misassembly of the spay arm water delivery system.
1. Check for water hardness. If hard, instruct the customer to use the maximum detergent, or try pouring 1/8 cup of Glass
Magic into the bottom of dishwasher. To clean the dishwasher, recommend running with 1/2 cup of white vinegar sitting upright in the dish rack.
2. Check water hardness. If below 10 grains, instruct customer to use less detergent.
3. Disconnect the drain hose at the air gap.
Elevate the hose above the dishwasher and fill with water. If water flows into dishwasher, replace the drain hose.
6-8
PROBLEM
Poor drying performance.
POSSIBLE CAUSE SOLUTION
1. Customer use issues.
2. Heater problem. Check for an open connection or component in the heater circuit, an open in the heater, or a faulty heater drive circuit on control.
I. Recommend using Rinse Aid. Instruct on how to fill and monitor Rinse Aid.
2. Check all components and connections in the water heating circuit. Check the resistances of all connections and components between heater and control.
Check the resistance of heater, and its operation during the Diagnostics cycle.
3. Check the resistance of all connections between the dispenser and the control.
3. Rinse Aid dispenser not dispensing due to a loose harness connection.
4. Open coil on the dispenser solenoid.
5. Faulty dispenser drive circuit on control.
4. Disconnect the leads and check the resistance of the dispenser coil.
5. Check the operation of the dispenser by the control during Diagnostics.
Lid not opening after cycle.
Lid not latching.
1. Faulty lid actuator.
2. Foreign material in plunger housing.
3. Customer use issues.
1. Check all components and connections in the lid actuator circuit. Check the resistances of all connections and components between the control and the lid actuator. Check the resistance of the actuator, and check to see that the lever from the actuator engages the slider in the latch assembly.
2. Manually push plunger down and inspect the area for foreign matter. Remove or replace the housing as needed.
3. Instruct customer not to leave items on the lid during the wash cycle.
1. Lid knob not oriented properly.
2. Foreign material in plunger housing.
1. Check that the indicator on the knob aligns with the indicator on the lid. If misaligned, repair or replace the lid actuator assembly.
2. Manually push the plunger down and inspect the area for foreign matter. Remove or replace the housing as needed.
