How to Fix / Troubleshooting

Safety first: Unplug the dishwasher before removing the door panel.

  • Check child lock: Verify that any child lock function is not activated. Refer to the user manual to disable it.
  • Reset appliance: Turn off power at the breaker for 5 minutes, then restore power and try again.
  • Inspect control panel: Remove the inner door panel to access the user interface board. Check for moisture, corrosion, or loose connectors.
  • Check ribbon cable: Ensure the flat cable between the UI and main board is fully seated and not damaged. Reseat both ends.
  • Replace UI if needed: If specific buttons do not respond and the panel shows signs of failure, replace the user interface assembly with the correct De Dietrich part.
