Your KitchenAid dishwasher is unable to initiate its operation despite being powered on. This issue may arise due to problems with the water supply, a malfunctioning main control board, an incorrect timer setting, or an issue with the door latch switch.

Reasons Why KitchenAid Dishwasher Won’t Start But Has Power

  1. Water Supply Issues

    • Insufficient or disrupted water flow can prevent your KitchenAid dishwasher from starting, despite having power.
    • Check the water supply line for kinks or damage, which can impede water flow.
    • Ensure the water supply line is securely connected and the inlet valve is in the open position. Consider replacing a malfunctioning inlet valve.
  2. Main Control Board Problems

    • The main control board serves as the brain of your KitchenAid dishwasher.
    • If it's defective, it won't provide the necessary power to initiate the dishwasher.
    • Troubleshoot the main control board by checking for system glitches or loose connections, and if necessary, replace it with a new one.
  3. Faulty Dishwasher Timer

    • The timer allocates power to various functions at specific times.
    • A malfunctioning timer can result in insufficient power for the dishwasher to start.
    • Resolve this issue by replacing the faulty timer with a new one.
  4. Issues with the Door Latch Switch

    • A door latch switch holds the dishwasher door closed and communicates its status to the main control board.
    • A jammed or broken door latch switch can prevent the dishwasher from starting.
    • If the latch is broken, it should be replaced. If it's jammed, clear any obstructions.
  5. Malfunctioning Drive Motor

Alternative to KitchenAid Dishwasher

Samsung Dishwashers

Samsung offers a range of modern dishwashers with smart features, including Wi-Fi connectivity, flexible loading options, and various wash cycles. Incorrect Dishwasher Settings

    • Ensure you have selected a wash cycle; the dishwasher won't start without one.
    • Deactivate the child lock or control lock functions if they are active.
    • Clear any delay start settings if present.
    • Disable sleep mode if it's preventing the dishwasher from starting.
  1. Start Switch Issues

    • If the start switch is malfunctioning, it can prevent your KitchenAid dishwasher from starting. Diagnose and repair it if possible, or replace it if needed.
  2. Selector Switch Problems

    • Selector switches are used to choose wash cycles, and malfunctioning ones should be replaced.
    • To do this, disconnect the dishwasher, access the selector switch, and test each one for continuity. Replace switches without continuity.
  3. Faulty Electronic Control Board

    • The electronic control board oversees essential dishwasher functions like washing, filling, and drying.
    • Test the board for continuity using a multimeter and replace it if there's no continuity. Replacement involves several steps and specific tools.
    • Disengage the control panel from the inner door panel by lifting the locking tab and gently shifting it to the left.
    • Release the remaining locking tabs and take off the cover of the electronic control board.
    • Remove the connector brace for the harness and the cover for the connector box.
    • Disconnect all the wires from the electronic control board and dispose of the old board.
    • Connect all the wires to the new electronic control board, reinstall the wire harness connector brace and connector box cover, and put back the electronic control board cover.
    • Insert the new control board into the mounting slots, sliding it to the right.
    • Reconnect the user interface (UI) wire harness.
    • Affix the outer door panel and control panel to the inner door panel.
    • Secure the assembly by reinstalling all the mounting screws.
    • Finally, restore power to the dishwasher by either plugging it in or resetting the circuit breaker.
  4. The Unit Has Faulty Electrical Wires

  • Your dishwasher may fail to start due to malfunctioning electrical wires, which can be a result of a power surge.
  • These wires serve as the connections between various components like motor pumps and the control panel.
  • When the wires experience burnout, it can disrupt the proper functioning of the dishwasher.
  • To resolve this problem, replace the damaged wires as needed.
  1.  Faulty Water Valve

  • If the water valve in your KitchenAid dishwasher encounters issues, it can lead to startup problems.
  • Possible reasons for water valve issues include turning off the water supply at the source, clogs in the supply hose, kinks or bends in the water hose, or a problem with the inlet valve.
  • If there are water-related problems, an error code may be displayed on the control panel.
  • Troubleshoot these issues appropriately by ensuring the water supply is turned on, clearing hose clogs, and straightening any kinks or bends in the hose.


When your KitchenAid dishwasher has power but refuses to start, it can be attributed to a range of underlying issues. It is important to diagnose the problem carefully to pinpoint the exact cause and apply the appropriate solution.

Whether it's a water supply problem, a malfunctioning main control board, a faulty timer, door latch switch issues, a problematic drive motor, incorrect dishwasher settings, issues with the start switch, or concerns with electrical wiring or the water valve, each of these potential culprits must be addressed meticulously to ensure the proper operation of your dishwasher.

Remember that some of these issues can be resolved with simple troubleshooting and maintenance steps, while others may require more advanced repairs or component replacements.

Regular maintenance and addressing any problems promptly can help keep your KitchenAid dishwasher running smoothly, ensuring that it consistently provides clean and hassle-free dishwashing.

By understanding and addressing the specific issue at hand, you can regain the convenience and efficiency of your dishwasher, making your kitchen tasks more manageable and stress-free.
