Check the Water Container and Seals

- Inspect the container for cracks or damage. If you notice any, replacing the water container is essential.
- Check the rubber seals or gaskets around the water tank inlet for wear or displacement. Worn or misaligned seals are common causes of leaks.

Examine the Brew Group and Internal Components
Remove the brewing unit (if accessible) according to your model’s instructions. Look for signs of mineral buildup, cracks, or loose fittings. Mineral deposits can cause blockages that lead to water backflow.
Clean the brew group thoroughly with a damp cloth and descaling solution if necessary. Ensure all components are seated correctly before reassembling.
Perform a Descaling Process
Mineral deposits from hard water can cause internal blockages, resulting in leaks. Use a descaling solution like the De’Longhi EcoDecalk, following the manufacturer’s instructions.
Run the descaling cycle without coffee beans to flush out mineral buildup. Regular descaling every 2-3 months will keep your machine functioning smoothly and prevent leaks.
Inspect the Drip Tray and External Hoses
- Check the drip tray for overflowing or improper placement. Empty and clean it regularly.
- Inspect external hoses and connections for cracks, loose fittings, or leaks. Tighten or replace parts as needed.
- Ensure all external components are correctly reattached after cleaning or maintenance.
Replace Worn or Damaged Parts
If you identify damaged seals, gaskets, or other components during inspection, replacing them is often the best fix. Use genuine replacement parts like the De’Longhi Water Filter to maintain optimal performance.
Follow your model’s manual for specific part replacement procedures or consult a professional technician for complex repairs.
