Perform a Manual Reset of the Descale Light

  • Turn off the machine and unplug it from the power source.
  • Wait about 10 seconds, then plug it back in.
  • Press and hold the descaling button (or combination of buttons specified in your manual) for 5-10 seconds until the light resets.

Descale Your Machine Properly

If the light remains, it’s time to descale. Use a recommended descaler such as the De’Longhi EcoDecalk Descaler, which is eco-friendly and safe for your machine.

  • Prepare the descaling solution according to package instructions.
  • Fill the water tank with the solution.
  • Run the descaling cycle as per your machine’s manual.
  • Rinse thoroughly with fresh water afterward to remove any residual descaler.

Reset the Descale Indicator After Cleaning

After descaling, reset the indicator manually if it doesn’t reset automatically. Refer to your user manual for specific reset instructions, often involving pressing and holding certain buttons during startup.

Prevent Future Descale Light Issues

  • Use filtered water with a demineralizer like the De’Longhi Replacement Water Filter (asin=B00CXQ9GQ8) to reduce mineral buildup.
  • Regularly descale every 2-3 months or as recommended based on water hardness.
  • Follow proper maintenance routines to keep your machine in top condition.
