- Visually inspect the water tank, internal components, and the area around the drip tray for any visible leaks or water pooling.

Check and Replace the Water Filter
If your machine uses a water filter, a clogged or improperly fitted filter can cause leaks. Remove the filter and inspect it for debris or buildup. If it appears dirty or damaged, replace it with a new De’Longhi Replacement Water Filter (ASIN B00CXQ9GQ8). Reinstall the filter securely following the manufacturer’s instructions.
Regularly replacing the filter ensures optimal water flow and prevents mineral deposits that can lead to leaks over time.
Inspect and Tighten Seals and Connections
Loose or worn seals are common culprits for water leaks. Check the water tank, brew group, and any visible internal seals for cracks or looseness. Use a soft cloth to clean the seals and gently tighten any loose fittings. If seals are damaged, replace them with compatible parts from De’Longhi or authorized suppliers.
Be cautious not to overtighten, as this can cause further damage.
Descale Your Machine
Mineral buildup from hard water can cause internal blockages and leaks. Use a descaling solution like De’Longhi EcoDecalk (ASIN B0021IOTTW) or EcoDecalk Descaler (ASIN B008YETL18) according to the instructions. Regular descaling (every 2-3 months) maintains proper water flow and prevents leaks caused by scale deposits.
Ensure you run a full descaling cycle and rinse thoroughly afterward.
Perform a Test Run and Final Inspection
After completing the above steps, plug in the machine and run a test brew cycle without coffee to observe if the leak persists. Check all connections and seals again during this cycle. If water leaks again, identify if a specific component needs replacement or professional repair.
Always follow safety guidelines and unplug the machine before making further adjustments.
