    Most common repairs needed to fix a Samsung dishwasher

    Electronic Control Board Replacement

    A dishwasher that won’t turn off could have a defective electronic control board. The control board should turn off the control panel when the dishwasher is idle. When the control panel stays lit constantly, a bad relay or failed logic in the electronic control board could be causing the problem. When your dishwasher won’t turn off, have a Sears Home Services Technician check out the controls and replace the electronic control board if it’s defective.


    User Interface Control Replacement

    A damaged user interface control won’t turn off the dishwasher when the cycle finishes. The power button or another button on the user interface control will cause the control panel to stay on constantly. Checking the user interface control to determine whether it is damaged requires special tools and diagnostic equipment. When your dishwasher won’t turn off, have a Sears Home Services Repair Expert visit your home and replace the user interface control if it’s damaged.

    Drain Pump Replacement

    When you hear the dishwasher running constantly and it won’t turn off, a failed drain pump could be causing the problem. When the control detects water in the sump after the wash cycle ends, it may run the drain pump to remove the water. When a failed drain pump doesn’t remove the water, the control may continue to run the drain pump indefinitely. If water stays in the dishwasher tub and you hear the drain pump running constantly, schedule a Sears Home Services Repair Expert to examine the dishwasher and replace the failed drain pump.

    What to expect when you experience a Samsung dishwasher won't turn off issue

    How is the won't turn off problem fixed?

    Correcting most won't turn off problems usually involves replacing the electronic control board, user interface control or drain pump. 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 won't turn off

    When the dishwasher won't turn off 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 won't turn off 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.

    Samsung Dishwasher Flashing Heavy – Won’t Turn Off

    The Samsung dishwasher flashing the Heavy light and not turning off indicates that the control detects a drain problem, leak or too much water in the dishwasher.

    For Samsung dishwasher models that have the Express 60 cycle, the flashing Heavy light indicates that the control detects too much water in the dishwasher. This is often caused by a drain problem. Follow these troubleshooting tips to fix the problem so the dishwasher will work again:

    • Check the kitchen sink drain. Clear a clog in the kitchen sink if it’s not draining.
    • Run the garbage disposal if its chamber is full of food and blocking the dishwasher drain path.
    • Check the air gap if you have one installed in the dishwasher drain line. Clear the air gap if you find it clogged.
    • If you recently installed a new garbage disposal and didn’t remove the knock-out plug for the dishwasher drain hose connection, remove that knock-out plug so the dishwasher will drain properly.
    • Check the end of the dishwasher drain hose for grease and/or debris that could be clogging the drain hose. Remove a grease or debris in this area so the dishwasher will drain.

    If these basic troubleshooting tips don’t help, schedule dishwasher repair service to have an appliance technician fix your dishwasher.

    If you have a Samsung dishwasher without the Express 60 cycle, the flashing Heavy light indicates that the dishwasher’s leak sensor detects moisture. The dishwasher won’t turn off and the drain pump will run.

    Check under the dishwasher for a leak. Have a service technician repair the dishwasher if it’s leaking from under the tub.

    If you don’t find a leak under the dishwasher, shut off the water supply cut-off valve in case the water inlet valve is leaking. Schedule dishwasher repair service and we’ll send a Sears Home Services technician visit your home to 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.
