Identify the Cause of the Stuck Descale Light

The most common reasons are mineral buildup in the machine’s sensors or residual limescale that hasn’t been properly cleaned during previous descales. Sometimes, the machine’s internal sensors may fail or become dirty, causing the alert to stay on even after descaling.

Perform a Manual Descale Cycle

  1. Fill the water tank with water and add an appropriate descaling solution, such as De’Longhi EcoDecalk.
  2. Place a container under the coffee spout to catch the descaling solution.
  3. Turn on the machine and follow the descaling procedure outlined in your user manual, typically starting the descaling mode and running it through the entire cycle.
  4. Once completed, rinse the water tank thoroughly and fill it with fresh water.
  5. Run a rinsing cycle to clear any residual descaling solution.

Reset the Descale Light

After descaling, you may need to manually reset the descale indicator. Access the machine’s menu (refer to your user manual) and select the reset or descale indicator reset option. This should turn off the warning light.

Check and Clean Sensors

If the light remains, inspect the sensors inside the machine, especially near the water tank and boiler. Gently clean them with a soft, damp cloth to remove any mineral buildup or dirt that could be causing false readings.

Prevent Future Descale Issues

  • Use filtered or soft water to reduce mineral deposits.
  • Perform regular descaling every 2-3 months, depending on usage.
  • Utilize high-quality descaling solutions to ensure effective cleaning.
