Step 2: Inspect the Water Tank and Connections

Check the water tank for cracks or damage. Ensure it is seated correctly in its compartment. Examine the water inlet and outlet hoses for any signs of wear, cracks, or loose fittings.

If hoses are disconnected or damaged, replace or reconnect them securely. Tighten any loose fittings to prevent leaks.

Step 3: Examine the Seals and Gaskets

Leaking often occurs when seals or gaskets are worn or damaged. Look around the brew unit, water reservoir, and internal connections for signs of deterioration or cracks.

If you spot worn or cracked gaskets, replacing them is essential. Consult your user manual for specific part numbers or contact De’Longhi support for replacement parts.

Step 4: Clean and Descale Your Machine

Mineral buildup can cause blockages and leaks. Use a descaling solution like De’Longhi EcoDecalk Descaler, following the instructions for your machine. Regular descaling (every 1-3 months) maintains optimal performance.

After descaling, rinse the system thoroughly with clean water to remove any residue that could cause leaks.

Step 5: Test the Machine and Final Checks

After reassembling and ensuring all parts are secure, plug in your machine. Fill the water tank and run a test brew without coffee to observe if the leak persists.

If water leaks continue, double-check all connections, seals, and hoses. Tighten or replace parts as needed. If the leak persists after these steps, consider professional service.

Tips and Warnings

  • Always unplug: Never attempt repairs on a plugged-in machine to avoid electrical shock.
  • Use genuine parts: For seals and gaskets, use manufacturer-recommended replacements to ensure compatibility and safety.
  • Regular maintenance: Descale and replace filters periodically to prevent mineral buildup that can cause leaks.
  • Handle with care: Be gentle when inspecting internal components to avoid further damage.
  • Seek professional help: If unsure or unable to fix the leak, contact authorized service centers.
