Samsung Dishwasher Touchpad Not Working

A Samsung dishwasher touchpad not working can be frustrating, but it’s a common issue that can often be resolved with some troubleshooting. In this guide, we’ll walk you through the steps to diagnose and potentially fix the problem with your Samsung dishwasher’s touchpad.

Initial Checks:


A dirty or greasy touchpad can cause it to become unresponsive. Here’s how to clean it:

  1. Power Off:

    • Turn off the dishwasher and unplug it for safety.
  2. Cleaning Solution:

    • Mix a solution of warm water and a few drops of mild dish soap.
  3. Cleaning Cloth:

    • Dampen a soft cloth or sponge with the solution, making sure it’s not too wet.
  4. Gentle Cleaning:

    • Gently wipe down the touchpad, paying attention to any stubborn spots.
  5. Dry Thoroughly:

    • Allow the touchpad to air dry completely before plugging the dishwasher back in and turning it on.

Soft Reset:

Sometimes, a soft reset can resolve minor software glitches:

  1. Power Off:

    • Turn off the dishwasher and unplug it.
  2. Wait:

    • Leave it unplugged for at least 10 minutes to allow any residual power to drain.
  3. Power On:

    • Plug the dishwasher back in and turn it on. Check if the touchpad is now working.

Check for Error Codes:

  1. Samsung dishwashers often display error codes when something is wrong. Refer to your user manual to interpret the error code displayed on the control panel.

Check for Loose Connections:

  1. Power Supply:

    • Ensure the dishwasher’s power cable is securely connected.
  2. Control Panel Connections:

    • Carefully open the dishwasher’s control panel to access the touchpad’s connections. Ensure they are firmly connected.

Control Panel Replacement:

If none of the above steps work, it’s possible that the touchpad or control panel itself is faulty and needs replacement. In such cases:

  1. Contact Samsung Support:
    • Reach out to Samsung customer support or a certified technician for further assistance.

Firmware Update:

Outdated firmware can sometimes cause issues with the touchpad’s functionality. Check if there’s a firmware update available for your Samsung dishwasher and follow the manufacturer’s instructions for updating it.

Keypad Test:

Samsung dishwashers often have a diagnostic mode that allows you to test individual components, including the touchpad. Here’s how to access it:

  1. Power Off:

    • Make sure the dishwasher is off.
  2. Press and Hold:

    • Press and hold the “Heavy” and “Delicate” buttons simultaneously for about 3 seconds.
  3. Diagnostic Mode:

    • The control panel should enter diagnostic mode. You can now test each button on the touchpad to see if they respond.
  4. Exit Diagnostic Mode:

    • To exit diagnostic mode, simply turn off the dishwasher.

Physical Inspection:

Inspect the touchpad for physical damage or wear and tear. If you notice any cracks, loose buttons, or other visible issues, it may be necessary to replace the touchpad or the entire control panel.

Professional Repair:

If none of the above steps resolve the issue, it’s best to consult a professional technician who is experienced with Samsung dishwasher repairs. They can perform a more in-depth diagnosis, replace faulty components, and ensure your dishwasher is back to optimal working condition.
