Step 1: Turn Off and Unplug Your Machine
Before beginning any troubleshooting, ensure your espresso machine is turned off and unplugged from the power source. This prevents accidental activation or electrical hazards. Remove the water tank and any removable parts to inspect for leaks more easily.
Carefully examine the machine for visible water or damp areas, especially around the water tank connection, drip tray, and internal components if accessible. Identifying the leak source is crucial for effective repair.

Step 2: Check the Water Tank and Connection Points
- Remove the water tank and inspect its edges and the connection port for cracks or damage. If the tank is cracked, it should be replaced.
- Ensure the water tank is seated properly when reattaching. A loose connection can cause water to leak out.
- Look for mineral deposits or debris around the connection points, which can prevent a tight seal. Clean these areas gently with a soft cloth or brush.
If the water tank or its connection appears damaged or worn, replacing the water filter (if applicable) or the tank itself may resolve the leak.
Step 3: Inspect Internal Seals and Gaskets
Leaking often occurs due to worn or damaged seals and gaskets inside the machine. These components keep water from escaping during operation.
- Access the internal parts carefully, following the manufacturer’s instructions or user manual. Be cautious to avoid damaging sensitive components.
- Look for cracks, tears, or mineral buildup on seals and gaskets—particularly around the brew group and water pathways.
- Replace any compromised seals with genuine De’Longhi replacement parts, which you can find using the ASIN B00CXQ9GQ8 for water filters or similar parts.
Regularly inspecting these parts prevents leaks and maintains optimal performance.
Step 4: Descale and Clean the Machine
Mineral deposits from hard water can cause internal blockages, leading to water leaks. Regular descaling is essential for maintaining your machine.
Use a descaling solution recommended by De’Longhi, such as the EcoDecalk Descaler, to remove limescale buildup. Follow the instructions provided with the descaler for safe and effective cleaning.
- Run a descaling cycle through the machine, ensuring all internal pipes and components are cleared of deposits.
- After descaling, rinse thoroughly to remove any residual solution.
This maintenance step can prevent leaks caused by clogged internal pathways and improve the overall functioning of your espresso machine.
Step 5: Reassemble and Test the Machine
Once you’ve checked and replaced worn parts and descaled the machine, reassemble all components carefully. Ensure that everything is positioned correctly and securely.
Fill the water tank, plug in the machine, and run a test brew without coffee to check for leaks. Observe the connection points and internal areas closely. If the leak persists, revisit the previous steps or consider professional repair.
Always consult your user manual for specific disassembly and reassembly instructions to avoid damaging your machine.
Tips and Warnings for Safe and Effective Troubleshooting
- Always unplug the machine before performing maintenance.
- Use genuine De’Longhi replacement parts for seals and filters.
- Do not attempt to repair internal components beyond your comfort level; seek professional help if needed.
- Regularly descale your machine to prevent mineral buildup and leaks.
- Be cautious when handling internal parts to avoid damaging delicate components.
