Descale Your Machine Properly

  1. Fill the water tank with the appropriate descaling solution (e.g., De’Longhi EcoDecalk or EcoDecalk Descaler).
  2. Place a container under the steam wand and coffee outlet to catch water.
  3. Follow your machine’s manual to initiate the descaling cycle, typically by pressing specific buttons.
  4. Complete the cycle and rinse the water tank thoroughly with fresh water.

Reset the Descale Light

  1. Turn on the machine and ensure it is in standby mode.
  2. Press and hold the ‘Descale’ button or the combination of buttons specified in your user manual (commonly ‘Coffee’ and ‘Steam’ buttons simultaneously) for about 5-10 seconds.
  3. Release the buttons when the descale light begins flashing or turns off.
  4. If the light remains on, repeat the process or consult your manual for specific steps.

Check and Confirm

After resetting, turn off and unplug the machine. Wait a moment, then restart it to verify that the descale light is no longer illuminated. Run a short brew cycle to confirm proper operation.

Tips and Warnings

  • Always use genuine descaling products recommended by De’Longhi to avoid sensor or system damage.
  • Perform descaling every 2-3 months or as indicated by your water hardness level.
