Perform a Manual Reset of the Descale Light

  1. Turn off your espresso machine and unplug it from the power source.
  2. Wait for at least 15 minutes to reset internal electronics.
  3. Plug the machine back in and turn it on.
  4. Press and hold the ‘Descale’ button (or as specified in your manual) for about 10 seconds until the light flashes or resets.

Run a Descaling Cycle

  • Fill the water tank with a descaling solution like the EcoDecalk or EcoDecalk Descaler. Follow the product instructions for dilution.
  • Place a container under the spouts to catch water.
  • Start the descaling process as instructed in your manual. Usually, this involves pressing a specific button combination.
  • Allow the cycle to complete, then rinse by running plain water through the machine to clear any residues.

Check Water Filter and Water Quality

Ensure your water filter (if used) is properly installed and not overdue for replacement. A clogged or expired filter can cause false alerts or descaling issues. Consider replacing it with the De’Longhi Replacement Water Filter for optimal performance.

Final Tips and Precautions

  • Always use recommended descaling solutions to avoid damaging your machine.
  • Avoid using citric acid or harsh chemicals not designed for espresso machines.
  • If the light persists after these steps, contact De’Longhi customer support for assistance.
