Step 1: Confirm the Need for Descaling
Ensure the machine actually needs descaling. The indicator may stay on if the machine detects scale buildup, but sometimes it’s a false alert. Run a brief water cycle to see if the light persists after the cycle completes.

Step 2: Perform a Manual Descale
- Fill the water tank with a descaling solution, such as De’Longhi EcoDecalk Descaler or a recommended alternative.
- Follow the machine’s instructions for initiating the descaling cycle—usually pressing and holding certain buttons.
- Run the descaling process completely, then rinse with fresh water.
Step 3: Reset the Descale Light
After descaling, reset the indicator by pressing and holding the ‘Descale’ button or following the specific reset instructions in your user manual. This often involves holding the button for a few seconds until the light turns off.
Step 4: Check the Sensor and Water Filter
- Inspect the water level sensor for any debris or scale build-up. Clean gently with a soft cloth if needed.
- If you use a water filter, replace it regularly. Consider installing a replacement water filter, like the De’Longhi DLSC002, to prevent future issues.
