Identify the Source of the Leak
The first step is to determine where the water is leaking from. Common leak points include the water tank, the brew head, the drainage tray, or internal connections. Carefully observe the machine during operation or after it has been idle for a few minutes. Check for water dripping from the water tank seal, the brew head area, or along the internal tubing.
Once you spot the leak source, you can focus on specific parts. For example, if water drips from the water tank area, the tank seal or connection might be faulty. If water leaks from the brew head, the gasket or internal valves could be the cause. Correct identification is crucial for an effective fix.

Check and Replace Seals and Gaskets
Seals and gaskets are vital for preventing leaks in your espresso machine. Over time, they can become brittle, cracked, or worn out, especially if the machine is frequently descaled or used heavily. Inspect the water tank seal, brew head gasket, and any internal O-rings for signs of damage.
If you notice cracks, deformation, or mineral deposits, consider replacing these parts. The De’Longhi Magnifica Evo Next uses specific seals that can be replaced easily. Using genuine replacement parts ensures proper fit and function. Follow the manufacturer’s instructions for removing and installing seals to avoid damage and ensure a tight seal.
Inspect Water Lines and Connections
Loose or cracked water lines are another common cause of leaks. Carefully check all visible hoses and fittings inside the machine, especially around the water pump and internal tubing. Tighten any loose fittings with appropriate tools, but avoid overtightening, which can cause damage.
If you find cracked or brittle hoses, replace them with compatible, high-quality hoses designed for espresso machines. Regular inspection and replacement help prevent future leaks and maintain optimal performance. Remember to always turn off and unplug the machine before handling internal components.
Descale Your Machine Regularly
Mineral buildup from hard water can cause blockages and internal pressure issues, leading to leaks. Regular descaling is essential for maintaining your De’Longhi espresso machine. Use a descaling solution recommended by De’Longhi, such as the EcoDecalk Descaler, for effective and safe cleaning.
Follow the descaling instructions provided with your machine and descaler. Usually, this involves running the solution through the machine, then rinsing thoroughly. Regular descaling, typically every 2-3 months depending on usage, prevents mineral deposits from causing internal leaks or blockages, extending your machine’s lifespan.
Use Genuine Replacement Parts and Preventative Maintenance
Using authentic De’Longhi parts, such as water filters and replacement gaskets, ensures compatibility and durability. The De’Longhi Replacement Water Filter, for example, can improve water quality and reduce mineral buildup, indirectly preventing leaks caused by scale.
Routine maintenance includes checking seals, cleaning internal components, and descaling. Addressing small issues early can prevent costly repairs and extensive leaks. Keep your machine in a dry environment, and avoid overfilling water reservoirs to minimize leaks.
