Professional Repair Time: 60-90 minutes
DIY Repair Time: 90-150 minutes
Difficulty Rating: Advanced (4/5) — Requires advanced technical knowledge, careful handling of electronic components, precise reconnection of 8-12 electrical connectors, attention to detail, understanding of multiple circuit functions

CRITICAL WARNING: This is an advanced repair requiring careful handling of electronic components and precise reconnection of multiple electrical connectors (typically 8-12 wire harnesses). If you are not comfortable working with electronic components or do not have the required tools, hire a professional appliance repair technician. Improper installation can cause electrical damage, component failure, or dishwasher malfunction.

1. Turn off power to the dishwasher at the circuit breaker to ensure complete power disconnection.
2. Close the water supply valve to the dishwasher to prevent water leakage during the repair.
3. Verify power is off by attempting to turn on the dishwasher. The dishwasher should not respond and the display should be blank.
4. Open the dishwasher door fully to provide access to the internal components.
5. Take multiple photos of the control board location, mounting, all electrical connector positions, and wire routing before disassembly. Document from multiple angles. This is absolutely critical for proper reassembly. Use a camera or smartphone to capture high-quality images.
6. Create a detailed connector map by photographing each of the 8-12 wire harnesses and labeling them with their function (motor, water inlet valve, drain pump, heating element, detergent dispenser, user interface, door latch, temperature sensors, power supply, etc.). Use masking tape to label each connector as you photograph it. Number each connector (1-12) for easy reference.
7. Remove the lower access panel or kick plate at the bottom of the dishwasher by removing the mounting screws (typically 2-4 screws).
8. Remove the dishwasher door panel by removing the screws securing the inner door panel to the outer door panel (typically located along the sides and top of the door). Carefully separate the inner panel from the outer panel.
9. Locate the electronic control board mounted on the inside of the dishwasher door or on the front panel behind the control panel area.
10. Take additional detailed photos of all electrical connectors before disconnecting. Photograph each connector from multiple angles to capture the connector type, orientation, wire colors, and pin positions.
11. Disconnect all electrical connectors from the old control board by pressing the locking tabs and pulling the connectors straight off. Do not pull on the wires—grasp the connector bodies. Label each connector with masking tape indicating its number (1-12), function, and original position.
12. Verify all connectors are disconnected by attempting to gently move the control board. The board should not be attached to any connectors.
13. Locate the control board mounting screws that secure the board and support bracket to the dishwasher door or panel (typically 4-6 mounting screws).
14. Remove the mounting screws using a Phillips screwdriver or nut driver.
15. Carefully remove the old control board from the dishwasher and place it on a clean work surface with adequate space for inspection.
16. Inspect the old control board for visible damage such as burned components, cracked solder joints, corrosion, discoloration, bulging capacitors, burned triacs or relays, or burned areas. This confirms the diagnosis.
17. Inspect the control board mounting location on the dishwasher door or panel for damage, corrosion, or debris. Clean the mounting area if necessary using a dry cloth.
18. Unpack the new W11087226 electronic control board from its packaging. Handle carefully to avoid damaging the board or components. Avoid touching the circuit board surface or electronic components.
19. Verify the control board specifications match the old board: board dimensions approximately 10-11 inches x 7-8 inches, connector types and positions (8-12 wire harnesses), mounting hole locations, relay and triac positions, support bracket design.
20. Compare the new control board to the old one to verify the dimensions, connector positions, mounting holes, and overall appearance match. Ensure you have the correct replacement part.
21. Inspect the new control board for any damage or defects before installation. The board should be intact with no visible damage, burned components, or cracked solder joints.
22. Position the new control board and support bracket on the dishwasher door or panel, aligning the mounting holes with the mounting points.
23. Install the mounting screws to secure the board and support bracket to the dishwasher door or panel. Tighten gently but firmly—do not overtighten, which can crack the board or mounting bracket.
24. Verify the control board is securely mounted and does not wobble or shift when gently pressed.
25. Reconnect all electrical connectors to the new control board by pushing each connector straight onto the board terminals until it clicks into place. Use your numbered and labeled connectors and detailed photos to ensure correct connector placement.
26. Verify each connector is fully seated by gently tugging on the connector. The connector should not pull off—it should be firmly seated.
27. Double-check all connector connections by comparing your installation to your detailed photos. Verify each of the 8-12 connectors is in the correct position and fully seated.
28. Verify no connectors are loose or partially seated by visually inspecting all connections. All connectors should be flush against the control board.
29. Reinstall the dishwasher door panel by positioning the inner panel against the outer panel and securing it with the mounting screws along the sides and top.
30. Reinstall the lower access panel or kick plate by securing it with the mounting screws.
31. Restore power at the circuit breaker.
32. Open the water supply valve to the dishwasher.
33. Turn on the dishwasher and observe the control panel display. The display should illuminate and show the default settings or welcome screen.
34. Test the control panel buttons by pressing various buttons. The buttons should respond and the display should change accordingly.
35. Run a short test cycle (approximately 10-15 minutes) to verify the dishwasher fills, washes, drains, and heats properly.
36. Verify the door latch engages when the cycle starts. The door should lock and remain locked during the cycle.
37. Monitor the dishwasher throughout the full cycle to verify proper operation of all functions including filling, washing, draining, heating, and drying.
38. Test multiple wash cycles with different settings to verify the control board operates properly under various conditions.
39. Listen for unusual noises from the control board area. The control board should operate quietly without clicking, buzzing, or humming sounds (except for normal relay clicking during cycle transitions).
40. Monitor the dishwasher for 24-48 hours to ensure the control board operates properly without issues.

Safety Notes: Always turn off power at the circuit breaker before working on the dishwasher to prevent electrical shock. Handle electronic components carefully to avoid damaging sensitive circuits. Do not touch the circuit board surface or electronic components with bare hands—use an anti-static wrist strap if available. Ensure all 8-12 electrical connectors are fully seated and secure before restoring power. This repair requires advanced technical knowledge and careful attention to detail—most homeowners should hire a professional appliance repair technician for this repair.

1. Document all 8-12 wire harnesses with detailed photos and create a comprehensive connector map before disconnecting. Take high-quality photos of each electrical connector from multiple angles, capturing the connector type, orientation, wire colors, and pin positions. Create a detailed connector map or reference guide with labels for each connector function (motor, water inlet valve, drain pump, heating element, detergent dispenser, user interface, door latch, temperature sensors, power supply, etc.). Number each connector (1-12) with masking tape as you photograph it. This documentation is critical for ensuring correct reconnection and avoiding costly mistakes.
2. Use a systematic numbering and labeling approach for all connectors. As you photograph each connector, immediately label it with masking tape indicating its number (1-12), function, and original position on the control board. Keep the labeled connectors organized in numerical order as you disconnect them. This prevents confusion during reassembly and ensures correct connector placement.
3. Verify connector orientation and pin alignment before reconnection. Some connectors can be inserted in the wrong orientation, which will prevent proper board operation or cause component damage. Compare each connector orientation to your reference photos before reconnecting. The connector should insert smoothly without forcing. If a connector does not insert smoothly, stop and verify the orientation is correct. Never force a connector onto the board.
4. Test the old control board with a multimeter before ordering a replacement. Use a multimeter set to voltage mode to test for power at the control board power input connector. A functioning board should show 120V AC at the power input connector. Zero voltage indicates a power supply failure or burned-out board. Test the motor output with the dishwasher set to wash cycle—you should see voltage at the motor connector. Test the water inlet valve output—you should see voltage when the dishwasher is filling. Testing prevents unnecessary board replacement and identifies upstream power supply issues.
5. Inspect all capacitors for signs of failure before concluding the board is faulty. Electrolytic capacitors commonly fail in control boards, causing loss of functions or erratic operation. Look for bulging, leaking, or burned capacitors on the board. Bulging or leaking capacitors indicate board failure and require replacement. A single failed capacitor can disable entire circuit sections. Capacitors typically fail after 5-10 years of operation.
6. Inspect all relays and triacs for signs of burning or corrosion. Relays control motor and pump activation, and triacs control heating element operation. Look for burned or discolored relays and triacs on the board. Burned components indicate board failure and require replacement. Relay or triac failure will prevent proper component activation even with a functioning microprocessor.
7. The control board manages both 120V AC circuits for logic and high-current circuits for motor and heating element control. Verify 120V AC is present at the power input connector before concluding the board is faulty. Loss of power will prevent all board operations. Check the household circuit breaker and verify the dishwasher is properly connected before replacing the control board.
8. Allow the dishwasher to complete a full cycle before evaluating performance. After installing the new control board, run a complete wash cycle (approximately 2-3 hours) to verify all functions operate properly throughout the entire cycle. Do not interrupt the cycle. Monitor the dishwasher throughout the cycle to verify filling, washing, draining, heating, and drying all function correctly.
9. The control board communicates with multiple sensors throughout the dishwasher. The temperature sensor monitors water temperature, the door latch sensor monitors door position, and other sensors monitor cycle progress. If the dishwasher does not operate properly after board replacement, verify all sensors are connected and functioning correctly by testing with a multimeter.
10. This repair is cost-effective compared to dishwasher replacement. The cost of control board replacement ($120-200) is far less than the cost of a new dishwasher ($800-2,500+). Replace the control board promptly when failure is detected to prevent the need for expensive dishwasher replacement and to restore proper dishwasher operation and all electronic functions.
