Perform a Manual Descale

  1. Fill the water reservoir with a descaling solution, such as De’Longhi EcoDecalk (or equivalent). Use the recommended amount per the product instructions.
  2. Place a large container under the brew spout to catch the solution.
  3. Start the descaling cycle through your machine’s menu. Follow prompts to run the full cycle.
  4. Once completed, rinse the water reservoir thoroughly and refill with fresh water.

Reset the Descale Light

After descaling, you need to reset the indicator:

  1. Access the menu and locate the ‘Descale’ or ‘Maintenance’ reset option.
  2. Select it and confirm the reset.
  3. Turn off and back on your machine to ensure the light turns off.

Verify the Descale Cycle Completion

Ensure the entire descaling process was completed properly. If the light persists, repeat the descaling and reset steps.

  • Do not skip steps during descaling, as incomplete cycles can trigger the light.
