Step 1: Turn Off and Unplug Your Machine
Before starting any troubleshooting, safety is paramount. Turn off your De’Longhi espresso machine and unplug it from the power outlet. Remove the water tank and any removable parts to access the internal components more easily. Empty the water tank and wipe it dry to prevent spills.

Step 2: Inspect for Visible Leaks and Blockages
- Check the water tank, hoses, and connection points for cracks, holes, or loose fittings.
- Look inside the water chamber and around the brew group for signs of water pooling or drips.
- Ensure the seals and gaskets, especially around the water tank and brew unit, are intact and properly seated.
If you notice any cracks or worn seals, these are likely the cause of the leak and need replacement.
Step 3: Clean and Descale the Machine
Mineral deposits from hard water can cause blockages and pressure buildup, leading to leaks. Use a descaling solution such as the De’Longhi EcoDecalk Descaler, following the manufacturer instructions, to remove scale buildup.
Regular cleaning not only prevents leaks but also maintains the quality of your coffee. For routine maintenance, run a descaling cycle every 2-3 months, depending on water hardness.
Step 4: Check and Replace Worn Seals or Gaskets
Over time, seals and gaskets can become brittle or worn out, allowing water to escape. Remove the water tank, brew group, and any other removable parts, then inspect the seals for cracks or deterioration.
If you find any damage, replace these parts with genuine De’Longhi replacements. Proper sealing ensures no water leaks occur during operation.
Step 5: Reassemble, Test, and Monitor
Once you’ve cleaned and replaced necessary parts, carefully reassemble your machine, ensuring all components are securely fitted. Fill the water tank and plug your machine back in.
Run a test cycle without coffee or with a small amount of water to check for leaks. Observe all connection points and internal areas. If water continues to leak, recheck your seals or consider professional repair.
