    Most common repairs needed to fix a LG dishwasher

    Electronic Control Board Replacement

    When your dishwasher is not starting a cycle, a defective electronic control board could be causing the problem. The control board will freeze up and fail to start a cycle when its internal memory and logic is corrupted. A failed internal electronic relay or bad electronic part on the circuit board could be causing the control board to freeze up and not start a cycle. Determining whether a control board is defective is difficult. Have a Sears Home Services technician diagnose and repair your dishwasher when it won’t start a cycle.


    User Interface Control Replacement

    When your dishwasher is not starting, a damaged user interface control could be causing the problem. The user interface control connects to the electronic control board through a wire harness and sends signals to the control board to help control the dishwashing cycle. A bad start key on the user interface control can prevent the dishwasher from beginning the cycle. Also, a stuck key on the user interface control can cause the electronic control board to stop all dishwasher operations and the dishwasher won’t work until the damaged user interface control is fixed. Have a Sears Home Services Repair Expert visit your home and replace the user interface control if it’s damaged.

    Wire Connector Replacement

    When your dishwasher is not starting, a stripped wire connector between the user interface control and electronic control board could be causing the problem. The wire harness between the electronic control board and user interface control must also stay connected to keep the dishwasher working. The control board will stop the dishwasher and keep it from starting when that wire harness is damaged or disconnected. When your dishwasher isn’t working, have a Sears Home Services Repair Expert visit your home and fix the problem.

    What to expect when you experience an LG dishwasher not starting issue

    How is the not starting problem fixed?

    Correcting most not starting problems usually involves replacing the electronic control board, user interface control or wire connector. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

    Sears Home Services recommendations for a dishwasher that is not starting

    When the dishwasher is not starting it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dishwasher failures.

    What to look out for with a dishwasher not starting diagnosis

    Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dishwasher problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

    LG Dishwasher Won’t Start Just Blinks Troubleshooting

    When your LG dishwasher won’t start and just blinks, follow these troubleshooting steps.

    1. Make sure the dishwasher door is fully shut. The cycle won’t start unless the control detects that the door is fully closed. Push in firmly on the dishwasher door to fully close it. Make sure nothing is blocking the door from shutting.
    2. See whether the control lock is engaged. Press and hold the button designated for the control lock for 3 seconds to disable the control lock if it’s turned on.
    3. Check for the delayed start feature enabled. If you find that your LG won’t start because the delayed start is on, press and hold the On/Off button for 3 seconds to disable the delayed start.
    4. Reset the electronic control board. Unplug the dishwasher or flip the power switch beside the sink off for 2 minutes to completely disconnect power from the dishwasher. Restore power and see if the dishwasher works after the electronic control board boots up.
    5. Check the water supply. Make sure the water supply cut-off valve is fully open. Open that water valve if you find it shut off.

    If your LG dishwasher won’t start and just blinks after following these basic troubleshooting tips, schedule dishwasher repair service to have a Sears Home Services technician visit your home and fix the problem.

    James called to give an estimated arrival time. He was professional and personable. He had 2 professional ideas of the problem and found 1 was correct, but he didn't stop there. He did a thorough check of the appliance. 1 small part was needed. He ordered the part to my house. Fortunately, he was able to schedule for the next week, just before Thanksgiving. As before, he called ahead, arrived and quickly fixed the problem. My appliance is working perfectly.
