Identify the Source of the Water Leak
The first step is to determine exactly where the water is leaking from. Common areas include the water reservoir, the brew head, the drain tray, or internal hoses.
Start by unplugging the machine and visually inspecting all accessible parts. Check for puddles or drips around the water reservoir, and see if water is escaping from the brew head or the drain tray. If the leak is internal, you may notice water pooling inside or underneath the machine.
Understanding the leak location helps you focus your troubleshooting efforts on the right components, saving time and avoiding unnecessary disassembly.

Check and Secure Water Connections
Loose or damaged water hoses are a common cause of leaks in fully automatic espresso machines like the De’Longhi Magnifica Evo. Carefully examine all visible hoses and connections, especially around the water reservoir and internal pathways.
If you find any hoses that are loose, secure them firmly. Look for cracks or signs of wear, which may require replacing the hoses. Ensure the water reservoir is properly seated and locked into position, as an improperly fitted reservoir can cause leaks.
For internal connections, if you’re comfortable, gently disconnect and reconnect hoses to ensure they are snug, but avoid forcing them, which can cause damage.
Inspect and Replace Seals and Gaskets
Worn or damaged seals and gaskets are often the culprits behind persistent leaks. Check around the brew head, water inlet, and other access points for signs of deterioration, such as cracks, brittleness, or missing pieces.
If you notice any compromised seals, replace them with original parts or compatible replacements. This is especially important for the water inlet gasket, which seals the connection between the water tank and the internal system.
Replacing seals and gaskets restores the airtight and watertight integrity of your machine, preventing leaks and ensuring optimal performance.
Descale and Clean Your Machine
Mineral deposits and lime scale buildup can obstruct water flow and cause leaks. Regular descaling with the right products, such as the De’Longhi EcoDecalk Descaler, is essential for maintaining your machine’s health.
Follow the manufacturer’s instructions for descaling, typically involving running a descaling solution through the machine’s water circuit. Additionally, clean the drip tray, water reservoir, and brew head regularly to prevent blockages and buildup.
Consistent cleaning reduces the risk of leaks caused by mineral deposits and keeps your coffee tasting fresh.
Replace Faulty Components and Seek Professional Help
If you’ve identified a damaged or worn part that cannot be repaired with simple cleaning or resealing, replacing it is the best course of action. Use original replacement parts to ensure compatibility and reliability.
For internal components like pumps or valves that are malfunctioning, consider contacting a professional repair service or De’Longhi authorized technician. Attempting complex repairs without proper tools and knowledge can cause further damage or void your warranty.
Always prioritize safety and professional assistance for complex issues.
