Perform a Manual Descaling Cycle

  • Fill the water tank with a descaling solution (recommend using De’Longhi EcoDecalk Descaler for eco-friendly, effective cleaning).
  • Follow the machine’s instructions to start the descaling process, usually by pressing specific buttons or menu options.
  • Allow the cycle to complete, then rinse thoroughly with fresh water.

Check and Clean the Water Sensor

Sometimes, mineral deposits can obstruct the water sensor, causing false alerts. Carefully locate the sensor (consult your user manual), and clean it gently with a soft, damp cloth. Avoid harsh chemicals to prevent damage.

Ensure Proper Water Quality and Regular Maintenance

  • Use filtered water to reduce mineral buildup.
  • Perform descaling every 2-3 months or as recommended.
  • Replace the water filter periodically if your model has one.

When to Contact Support

If the descale light remains stuck after trying these steps, your sensor may be faulty. Contact De’Longhi customer support or a qualified technician for assistance to avoid further damage.
