Perform a Descaling Cycle

  1. Fill the water tank with the appropriate descaling solution or fresh water if using a universal descaler like De’Longhi EcoDecalk.
  2. Turn on the machine and access the descaling mode as per the user manual.
  3. Follow the prompts to run the descaling process completely.
  4. Once finished, rinse the water tank and run a rinse cycle if prompted.

Reset the Descale Light Manually

If the light remains on after descaling, manually reset it by pressing and holding the descaling button(s) as instructed in your user manual, typically for 5-10 seconds. This will clear the alert if the machine recognizes the descaling is complete.

Check and Replace Water Filter

If your model uses a water filter, replace it regularly to prevent false descale alerts caused by sensor interference.

Troubleshooting Sensor or Electrical Issues

  • Inspect the water level sensor for dirt or damage; clean gently if needed.
  • If the sensor appears faulty, contact professional repair services or De’Longhi support.
