Perform a Proper Descaling Cycle

  1. Fill the water tank with a descaling solution (recommend De’Longhi EcoDecalk or EcoDecalk Descaler).
  2. Follow the machine’s descaling instructions from the user manual, typically involving starting the descaling program and running it through the entire procedure.
  3. Make sure to rinse thoroughly afterward with clean water to remove any residue.

Reset the Descale Light

  1. Turn off the machine and unplug it.
  2. Press and hold the descaling button (or follow your model’s specific reset procedure, often involving pressing a combination of buttons).
  3. While holding, plug the machine back in and turn it on.
  4. Release the buttons once the display shows a reset confirmation or the light turns off.

Check for Sensor and Software Issues

If the light remains stuck after descaling and resetting, inspect the water level sensors and contact support if needed. Sometimes, a software update or professional servicing is required.
