  • Control board

    • 🔧 Step-by-Step Repair Instructions

      🔧 Step 1: Test detergent dispenser wax motor

      1. Turn off the dishwasher’s circuit breaker at your home’s electrical panel to cut power to the unit.
      2. Open the dishwasher door fully and remove the bottom dish rack by lifting it straight up and out.
      3. Locate the detergent dispenser on the inside of the door – it’s the rectangular assembly approximately 8 inches from the top of the door and centered horizontally.
      4. Remove the two T20 Torx screws securing the dispenser assembly to the door inner panel (one screw at top left, one at top right of the dispenser housing).
      5. Pull the dispenser assembly forward approximately 2 inches to access the wiring harness on the back side.
      6. Locate the wax motor – it’s a cylindrical component approximately 2 inches long and 3/4 inch in diameter mounted to the right side of the dispenser mechanism with a single white wire connector and a single black wire connector.
      7. Disconnect both wire connectors by pulling them straight off the motor terminals with your fingers.
      8. Set your multimeter to the ohms (Ω) setting at 200 ohms range.
      9. Touch one multimeter probe to each of the two terminals on the wax motor (the metal tabs where the wires were connected).
      10. Read the resistance value on your multimeter display – a functional wax motor will show between 800 and 1,500 ohms.
      11. If the reading shows “OL” (open loop/infinite resistance) or reads below 700 ohms, the wax motor is defective and requires replacement (part number WD26X23456).
      12. If the resistance reading falls within the 800-1,500 ohm range, the wax motor is functioning correctly and the issue lies elsewhere in the dispenser system.

      🛠️ Step 2: Check timer or control board signal to dispenser

      1. Unplug the dishwasher from the electrical outlet or turn off the circuit breaker controlling the dishwasher.
      2. Remove the lower front access panel by unscrewing 2 Phillips-head screws (one at each bottom corner) using a Phillips #2 screwdriver.
      3. Pull the dishwasher door fully open to access the control panel area at the top of the door.
      4. Remove 6 Torx screws along the top inner door edge using a T20 Torx bit, spaced approximately 4 inches apart.
      5. Carefully lift the control panel forward and rotate it upward, exposing the control board mounted on the backside.
      6. Locate the white 6-pin connector labeled “DISPENSER” on the main control board, positioned in the upper right quadrant approximately 2 inches from the top edge.
      7. Set your multimeter to DC voltage, 20V range.
      8. Turn the power back on to the dishwasher.
      9. Insert the multimeter’s black probe into the ground terminal (bare metal chassis) and the red probe into pin 3 of the dispenser connector (this is the signal wire, typically orange or yellow).
      10. Start a wash cycle by pressing “Start/Reset” button.
      11. Advance to the rinse cycle by pressing and holding “Start/Reset” for 5 seconds, then pressing it twice more.
      12. Watch the multimeter reading when the dispenser should activate (typically 2-3 minutes into the rinse cycle). You should see a voltage spike from 0V to approximately 120V AC for 1-2 seconds.
      13. If voltage appears, the control board is functioning correctly—the problem lies in the dispenser mechanism or wiring between the board and dispenser.
      14. If no voltage appears, the control board requires replacement (part number WD21X24901).

      ⚙️ Step 3: Inspect dispenser door mechanism

      1. Locate the detergent dispenser assembly on the inside of the dishwasher door, positioned in the upper right corner approximately 8 inches from the top edge and 4 inches from the right edge.
      2. Examine the rectangular dispenser door (approximately 3 inches wide by 2 inches tall) for cracks, warping, or white residue buildup along the edges that would prevent proper sealing.
      3. Press the dispenser door latch button with your thumb to open the door manually. The door should swing open smoothly without resistance and stop at a 90-degree angle.
      4. Inspect the spring-loaded hinge mechanism located on the left side of the dispenser door. Look for a small silver coil spring (approximately 0.5 inches in diameter) that should be intact and not stretched beyond 1.5 inches in total length.
      5. Check the wax motor actuator, a cylindrical component (approximately 1 inch diameter, 2 inches long) mounted behind the dispenser assembly. Verify the white plastic rod extending from the wax motor moves freely in and out without binding.
      6. Examine the door latch mechanism on the right side of the dispenser. The plastic latch hook should extend 0.25 inches outward when engaged and retract completely when the door opens.
      7. Run your finger along the rubber gasket perimeter of the dispenser door opening. The gasket should be pliable, not cracked or hardened, with no gaps exceeding 1/16 inch.
      8. Remove any dried detergent residue using a flathead screwdriver wrapped in a damp cloth, scraping gently along the latch catch and door edges.
      9. Test the door by closing it firmly until you hear an audible click. Pull gently on the door edge—it should not open without pressing the release button.
      10. If the spring appears stretched beyond 1.5 inches, the door shows cracks, or the latch does not engage with a click, the dispenser assembly requires replacement (part number WD12X10462).

      🔩 Step 4: Test dispenser operation manually

      1. Locate the dispenser release actuator, a white plastic arm positioned on the right side of the dispenser assembly, approximately 2 inches from the top edge of the dispenser door.
      2. Press the actuator arm inward with your index finger using firm pressure (approximately 5-10 pounds of force) until you feel it depress 1/4 inch and hear an audible click.
      3. Watch the dispenser door as you press the actuator – the spring-loaded door should pop open immediately, swinging downward approximately 90 degrees from its closed position.
      4. Visually inspect inside the dispenser cavity for the detergent cup mechanism, a clear plastic cup mounted on a rotating bracket in the center of the dispenser compartment.
      5. Manually rotate the detergent cup clockwise using your fingers – it should turn smoothly through a 180-degree arc without resistance or grinding sounds.
      6. Release the actuator arm and manually push the dispenser door closed until it latches with an audible snap, requiring approximately 3-5 pounds of closing force.
      7. Check the wax motor (a cylindrical silver component measuring 1.5 inches in diameter, located on the back of the dispenser assembly) by gently pressing the plunger rod extending from its center – the rod should move inward 1/8 inch with light finger pressure, then spring back when released.
      8. Verify all wire connections remain firmly seated on the wax motor terminals – you should see two spade connectors (one red wire, one white wire) attached to metal tabs on the motor body.
      9. Test the rinse aid cap on the left side of the dispenser by turning it counterclockwise and lifting to remove, then reinstalling and turning clockwise until tight – it should seal completely without wobbling.

      đź“‹ Step 5: Replace wax motor or control board if faulty

      1. Locate the wax motor assembly on the right side of the dishwasher tub, approximately 8 inches up from the bottom and 3 inches from the right wall.
      2. Disconnect the white 2-wire connector attached to the wax motor by pulling the connector straight out from the motor housing—it will release with moderate pulling force.
      3. Use a flat-head screwdriver (1/4-inch width) to release the metal mounting clip securing the wax motor to the bracket by prying upward on the clip’s front edge.
      4. Pull the wax motor straight out from the mounting bracket—it will slide forward approximately 2 inches before coming free.
      5. Note the orientation of the actuator pin: it extends toward the front of the dishwasher and connects to the vent mechanism.
      6. Insert the new wax motor into the mounting bracket with the actuator pin facing forward until the motor housing sits flush against the bracket surface.
      7. Press the metal mounting clip down over the motor housing until you hear it click into the locked position.
      8. Connect the white 2-wire connector to the new wax motor terminals—push firmly until the connector seats completely with an audible click.
      9. Open the dishwasher door and locate the control panel at the top edge.
      10. Remove six T15 Torx screws along the top inner edge of the door, spaced approximately 4 inches apart.
      11. Lift the control panel up and forward, tilting it toward you to expose the back side where the control board mounts.
      12. Disconnect five wire harness connectors from the control board by pressing the release tab on each connector while pulling straight out.
      13. Remove four Phillips #2 screws securing the control board to the plastic mounting panel.
      14. Lift the old board straight up to remove it from the mounting posts.
      15. Align the new control board over the four mounting posts and press down firmly.
      16. Install four Phillips #2 screws and tighten until snug (approximately 8-10 inch-pounds).
      17. Reconnect all five wire harness connectors—each connector is keyed differently and will only fit its corresponding port.
