Step 2: Locate the Leak Source

  1. Check around the water reservoir, drip tray, and internal areas for visible water pooling or drips.
  2. Observe if the leak occurs during brewing, steaming, or when the machine is idle.
  3. Note any unusual sounds or constant water flow.

Step 3: Inspect and Tighten Seals and Hoses

Open the access panels or remove the water reservoir to examine seals, gaskets, and hoses. Look for cracks, wear, or loose fittings. Use a damp cloth to clean any mineral buildup around seals and connections. Tighten any loose fittings carefully, avoiding over-tightening which can cause damage.

Step 4: Clean and Descale the Machine

Mineral deposits can cause internal blockages leading to leaks. Use a descaling solution like De’Longhi EcoDecalk, following the manufacturer’s instructions. Regular descaling helps prevent leaks and maintains optimal performance.

Step 5: Replace Damaged Parts

If seals, gaskets, or hoses are cracked or worn out, replace them with genuine parts. For example, using a De’Longhi Replacement Water Filter can improve water quality and reduce mineral buildup, which may contribute to leaks. Consult your user manual or contact customer support for specific replacement parts.

Step 6: Test the Machine

After performing repairs or replacements, reassemble the machine, fill the water reservoir, and plug it in. Run a test brew or steam cycle to check for leaks. Observe carefully to ensure the leak has stopped and the machine operates smoothly.
