- Carefully inspect the area where water is leaking. Common spots include the water reservoir, brew group, steam wand, or internal components.

Check and Tighten Connections
- Remove the water reservoir and inspect the connection points for any loose fittings or seals.
- Ensure the water tank is properly seated and the valve is securely connected.
- Examine the brew group and steam wand connections for tightness.
- If any fittings are loose, tighten them gently but firmly to prevent further leaks.
Be cautious not to overtighten, as this could damage plastic components.
Inspect and Clean the Water Pathways
- Remove accessible parts like the brew group and steam wand for cleaning.
- Check for blockages or mineral buildup that may cause water to back up and leak.
- Use a soft brush or cloth to remove any debris or scale deposits.
- For stubborn scale, use a descaling solution like the De’Longhi EcoDecalk Descaler following the manufacturer’s instructions.
Regular cleaning prevents clogs and maintains optimal water flow.
Replace Worn or Damaged Seals and Gaskets
If you notice cracks or deterioration in the seals or gaskets, replacing them is essential. Use a compatible seal kit or contact De’Longhi customer service for genuine replacement parts. Follow your machine’s manual or online guides to replace seals safely. This is often the cause of slow leaks or water dripping during operation.
Test the Machine After Repairs
- Reassemble all parts securely.
- Refill the water reservoir and plug in the machine.
- Run a test cycle without coffee to observe if the leak persists.
- Check all connection points and internal areas for any signs of leakage during operation.
If the leak continues, revisit previous steps or consider professional repair services.
