Step 1: Unplug and Empty the Water Tank

Step 2: Check for Visible Leaks and Blockages
Examine the machine’s exterior and internal components for visible water leaks or pooling. Focus on the area around the boiler, hoses, and seals.
If you notice water around the boiler or internal hoses, these might be cracked or loose, requiring replacement or tightening.
Use a soft cloth to wipe away mineral deposits and check if the leak persists after cleaning.
Step 3: Inspect and Replace Worn Seals and Gaskets
Seals and gaskets inside the machine prevent water from escaping during operation. Over time, these can become brittle, cracked, or worn out.
Locate the seals around the water tank, boiler connections, and internal water pathways. If damaged, replace them using compatible parts from De’Longhi or authorized suppliers.
Ensure all seals are fitted snugly to prevent future leaks.
Step 4: Clean and Descale the Machine
Mineral deposits from hard water can cause blockages and buildup that lead to water pressure issues and leaks.
Use a descaler specifically designed for espresso machines, such as the De’Longhi EcoDecalk Descaler, following the manufacturer’s instructions.
Regular descaling (every 2-3 months) maintains optimal performance and helps prevent leaks caused by mineral buildup.
Step 5: Reassemble and Test the Machine
Once you’ve inspected, cleaned, and replaced any faulty parts, reassemble your espresso machine carefully.
Fill the water tank, plug in the machine, and run a test brew. Observe closely for any leaks or unusual behavior.
If the leak persists, revisit the previous steps or consider consulting a professional technician.
