Identify the Source of the Leak
Before fixing your De’Longhi espresso machine, pinpoint where the water is leaking from. Common leak sources include the water reservoir, internal hoses, seals, or the brew group. Carefully observe the machine while it is turned on or after use to see if water drips from specific areas.
Check the water reservoir for cracks or improper seating. Remove it and inspect the connection point. Also, examine the area around the brew group and drip tray for water pooling or drips. Identifying the exact source helps target the right fix and prevents unnecessary disassembly.

Check and Clean the Water Reservoir and Filter
- Turn off and unplug the machine. Remove the water reservoir carefully.
- Inspect for cracks or damage; replace if necessary. Clean the reservoir thoroughly with warm water and mild soap.
- If your machine uses a water filter, check if it’s clogged or overdue for replacement. Replace with a compatible filter, such as the De’Longhi Replacement Water Filter (asin=B00CXQ9GQ8).
- Reinsert the reservoir securely, ensuring it clicks into place.
- Plug in and run a test brew to see if the leak persists.
Regular cleaning and timely filter replacement can prevent leaks caused by mineral buildup and blockages. Proper seating of the reservoir is crucial to avoid leaks during operation.
Inspect and Replace Worn or Damaged Seals
Over time, seals within your espresso machine can wear out, crack, or become loose, leading to water leaks. Focus on the brew group seals, gasket, and any O-rings.
To inspect:
- Unplug the machine and remove the brew group following your user manual instructions.
- Carefully examine the seals and gaskets for signs of cracks, tears, or deformation.
- If damaged, replace them with genuine parts, which can often be ordered through De’Longhi customer service or authorized parts suppliers.
Reassemble the brew group, ensuring all seals are fitted correctly. A proper seal fit prevents water from escaping during brewing and internal leaks.
Perform Descaling to Remove Mineral Buildup
Mineral deposits from hard water can cause blockages and pressure issues, resulting in leaks. Regular descaling is essential for optimal performance.
Use a descaling solution like De’Longhi EcoDecalk (asin=B0021IOTTW or B008YETL18). Follow these steps:
- Fill the water reservoir with a mixture of descaling solution and water, according to the product instructions.
- Run a descaling cycle through your machine, following the user manual.
- After the cycle, rinse the reservoir and run several plain water cycles to clear any residue.
This maintenance step helps prevent mineral buildup that can cause internal pressure leaks and blockages.
Perform Safe Disassembly and Repair
If you’ve identified a specific part as faulty, such as a cracked hose or a broken valve, disassemble the necessary sections carefully. Always unplug the machine and allow it to cool down before starting.
Follow your user manual for detailed disassembly instructions. Use appropriate tools and handle parts gently to avoid further damage. Replace damaged components with OEM or compatible parts.
After repairs, reassemble and run a test cycle without coffee to confirm the leak is resolved.
Warning: If you are unsure or uncomfortable with disassembly, consult a professional technician to avoid voiding warranties or causing further damage.
