Identify the Leak Source
Begin by pinpointing where the water is leaking from your De’Longhi machine. Common leak points include the water reservoir, the area around the drip tray, hoses inside the machine, or the area near the brew group. Carefully inspect these zones for visible cracks, loose fittings, or water drips. In my experience, leaks often originate from a loose water reservoir or a worn-out gasket. Conduct a visual check with the machine unplugged and cooled down. If water is leaking from the bottom, check for cracks or damage in the drip tray or base. For leaks near the brew group, look for loose connections or mineral buildup that could impinge on proper sealing. Identifying the exact source will guide your repair approach and help prevent future issues.

Check and Replace the Water Filter
- Remove the water reservoir from the machine and empty it completely.
- Inspect the De’Longhi Replacement Water Filter for any damage or clogging. If it’s old or clogged, replace it with a new one to improve water flow and prevent leaks caused by excess pressure or mineral buildup.
- Reinstall the filter firmly into the reservoir, ensuring it’s seated correctly.
- Refill the reservoir with clean water, and run a test brew to see if the leak persists.
In my testing, replacing the water filter often resolves leaks caused by mineral deposits or pressure inconsistencies. Using high-quality filters like the De’Longhi DLSC002 can significantly improve performance and longevity.
Inspect and Tighten Internal Fittings and Hoses
Leaking can occur if internal hoses or fittings become loose over time. Carefully disassemble the accessible parts of your machine following the user manual. Check hoses connected to the water tank, brew group, and milk frother for secure fittings. Use a screwdriver or wrench as needed to tighten any loose clamps or fittings. Be cautious not to overtighten, which could cause cracks. During reassembly, ensure all parts are properly aligned and sealed. In my experience, a simple tightening can often stop minor leaks caused by loose connections.
Clean and Descale the Machine
Mineral buildup from hard water can cause blockages or cracks in internal components, leading to leaks. Use a descaling solution like the De’Longhi EcoDecalk (or similar, compatible solutions) following the manufacturer’s instructions. Regular descaling, typically every 2-3 months, keeps internal parts clean and prevents water from leaking due to mineral deposits. When cleaning, pay special attention to the brew group, water inlet, and seals. After descaling, run several water-only cycles to flush residual solution. This maintenance step is crucial for preventing leaks and maintaining optimal performance.
Replace Worn or Damaged Parts
If you identify cracks or damaged seals during your inspection, replacing worn components is essential. Focus on parts like gaskets, seals around the brew group, or any cracked hoses. Consult your user manual or contact De’Longhi customer support for genuine replacement parts. In my testing, replacing a damaged gasket or seal restored proper sealing and eliminated leaks. Always ensure the replacement parts are compatible with your model, such as the De’Longhi Magnifica Evo Next.
