Common CausesLimescale buildup, incomplete descaling cycles, or a faulty sensor.
Step-by-Step FixDescaling, resetting the indicator, and regular maintenance prevent recurrence.

Identify the Cause of the Stuck Descale Light

  • Ensure the machine has completed the descaling process. If not, the light remains active.
  • Check for mineral deposits or lime scale, especially in the water tank and internal components.
  • Verify if the sensor or control board might be malfunctioning.

Perform a Descaling Cycle

  1. Fill the water tank with the recommended descaling solution or a mixture of water and a descaling product like De’Longhi EcoDecalk.
  2. Start the descaling process by following your machine’s specific instructions, usually involving pressing certain buttons simultaneously.
  3. Allow the cycle to run completely, ensuring the machine dispenses fluid through the system.

Reset the Descale Indicator

  1. Turn on your espresso machine and ensure it is ready for use.
  2. Press and hold the descaling button or follow the reset procedure outlined in your user manual—often involving pressing a combination of buttons.
  3. Release the buttons once the indicator resets or the light turns off.

Check and Clean Internal Components

  • Remove the water tank, drip tray, and brew unit if accessible, and clean them thoroughly.
  • Use a soft cloth to wipe sensors or contacts that may be dirty or corroded.
  • Reassemble and run a rinse cycle to clear residual descaling solution.

Prevent Future Issues

  • Use filtered water with the De’Longhi Replacement Water Filter for better water quality.
  • Follow recommended descaling intervals, typically every 2-3 months depending on usage.
  • Regularly clean the machine’s removable parts and sensors.
