Perform a Manual Reset

  1. Turn off and unplug your espresso machine.
  2. Press and hold the ‘Descale’ button (or equivalent) for about 10 seconds.
  3. While holding, plug in the machine and continue holding for another 10 seconds.
  4. Release the button and turn the machine on. The descale light should reset.

Run a Descaling Cycle

If the reset doesn’t clear the light, run a descaling cycle using a descaler like De’Longhi EcoDecalk. Follow your machine’s specific descaling instructions, ensuring you:

  • Fill the water tank with the descaling solution.
  • Start the descaling process and let it complete fully.
  • Rinse thoroughly afterward to remove any residue.

Check and Replace Sensors or Filters

If the light remains after descaling, inspect the water filter (if installed) and replace it if necessary. Ensure sensors are clean and free of mineral deposits by gently wiping with a soft cloth.

Prevent Future Issues

  • Use a quality water filter like the De’Longhi Replacement Water Filter to reduce mineral buildup.
  • Descale regularly according to your usage—every 1-3 months.
  • Follow the manufacturer’s instructions for cleaning and maintenance.
