Perform a Manual Descale Cycle

  1. Fill the water tank with a descaling solution (preferably EcoDecalk or EcoDecalk compatible products).
  2. Place a large container under the coffee and steam outlets.
  3. Turn on the machine and access the descaling mode via the menu (refer to your user manual for specific steps).
  4. Run the descaling cycle according to your machine instructions.
  5. Once completed, rinse the water tank thoroughly and refill with fresh water.

Reset the Descale Indicator

  1. Ensure the descaling cycle is complete and the machine is turned off.
  2. Press and hold the descale button (or follow specific reset instructions from your manual, often involving pressing and holding certain buttons).
  3. Turn on the machine while holding the button(s) until the indicator resets or the light turns off.
  4. If unsure, consult your De’Longhi manual for exact reset procedures.

Check and Clean the Water Sensor

If the light remains on after descaling, the water sensor might be dirty or faulty. Carefully clean the water level sensor with a soft cloth and a little vinegar or mild cleaning solution. Make sure the sensor is dry before reassembling.

Regular Maintenance and Prevention

  • Use a water filter (like De’Longhi Replacement Water Filter, asin=B00CXQ9GQ8) to reduce limescale buildup.
  • Descale your machine every 2-3 months or as recommended based on water hardness.
  • Always use fresh, clean water and follow proper cleaning routines.
