Step 1: Unplug and Empty the Machine
Before beginning any repair, ensure safety by unplugging your De’Longhi espresso machine. Remove the water tank and empty any remaining water. This step prevents accidental spills and makes inspection easier.
Place a towel or container underneath to catch any residual water, and have a clean cloth ready for wiping up leaks or drips during the process.

Step 2: Inspect the Water Tank and Filter
Carefully remove the water tank and check for cracks or damage. Also, inspect the water filter (if installed) for clogs or buildup. A clogged filter or improper seating can cause water to leak from the tank area or back into the machine.
If you notice debris or scale, replacing the water filter (recommended model: De’Longhi Replacement Water Filter, asin=B00CXQ9GQ8) can improve water flow and prevent leaks.
Step 3: Examine Seals, Gaskets, and Hoses
Next, look closely at all visible seals, gaskets, and hoses inside the machine. Worn or cracked seals are common leak points. Use a flashlight if needed to identify hidden damage.
If you find damaged seals or gaskets, replace them promptly. This is often a quick fix that restores proper sealing and prevents water from escaping.
Step 4: Check for Mineral Buildup and Decalcify
Mineral deposits can cause internal blockages and leaks. Use a descaling solution like De’Longhi EcoDecalk Descaler (asin=B0021IOTTW or asin=B008YETL18) to clean your machine thoroughly.
Follow the instructions on the descaler packaging—typically, you’ll run a descaling cycle to dissolve limescale deposits. Regular decalcification prolongs your machine’s lifespan and avoids leak issues caused by mineral buildup.
Step 5: Test and Confirm the Repair
After completing inspections and repairs, reassemble your machine carefully. Fill the water tank, reinstall it securely, and plug in the machine.
Turn on your espresso maker and run a test cycle without coffee. Observe for any leaks or drips. If the leak persists, double-check seals, hoses, and the water tank for proper fit and integrity.
Additional Tips and Precautions
- Use genuine replacement parts: Always opt for authentic seals and filters to ensure compatibility and durability.
- Perform regular maintenance: Descale every 2-3 months or as recommended based on water hardness.
- Handle components gently: Avoid overtightening seals or forcing parts, which can cause damage.
Remember, if you’re unsure about handling internal components, consult a professional technician to avoid damaging your espresso machine.
