Ensure Proper Descaling
- Fill the water tank with fresh water and add a descaling solution recommended for De’Longhi machines, such as EcoDecalk.
- Run the descaling cycle as per your user manual, ensuring the machine dispenses the solution through the brew and steam outlets.
- After completing the cycle, rinse the water tank and run a few cycles with fresh water to clear any residual descaler.

Reset the Descale Indicator
- Turn off your machine and unplug it from the power source.
- Press and hold the ‘Descale’ button while plugging the machine back in.
- Continue holding the button until the descale light flashes or turns off, indicating a reset.
Check and Clean the Sensors
Sometimes, mineral deposits or dirt can interfere with the sensor that detects scale. Use a soft, damp cloth to gently clean the sensor area inside the water tank connection or relevant sensor ports. Avoid harsh chemicals.
Test After Reset
Fill the water tank with fresh water and turn on the machine. Run a brew cycle without coffee to ensure the descale light turns off and the machine operates normally.
Consult the Manual or Support
If the light remains on after these steps, refer to your user manual for model-specific instructions or contact De’Longhi customer support for professional assistance.
