Perform a Manual Descale Cycle
- Fill the water tank with a descaling solution (e.g., De’Longhi EcoDecalk or similar). Ensure you follow the manufacturer’s instructions for dilution.
- Turn on the machine and initiate the descaling program as per the user manual.
- Allow the cycle to complete fully, following any prompts or instructions on the display.
- Rinse the water tank and fill it with fresh water, then run a rinse cycle to clear any residual descaler.
Reset the Descale Indicator
After completing the descaling cycle, reset the descale light:
- Press and hold the descale button or combination of buttons as per your model’s manual (often the same button used for descale or a specific reset function).
- Hold for about 5 seconds until the light blinks or resets.
- Release and turn off the machine, then restart to check if the light clears.
Clean Sensors and Check for Obstructions
Use a soft, damp cloth to clean the water sensor located inside the water tank or near the water inlet. Make sure no scale deposits or dirt block the sensor’s contact points. Reassemble and restart the machine to see if the indicator resets.
Prevent Future Scale Buildup
- Use filtered water or replace the water filter regularly to reduce mineral deposits.
- Descale your machine every 2-3 months or as recommended, especially if you have hard water.
- Follow maintenance guidelines to keep sensors and internal parts clean.
