1. Confirm the Water Tank Is Properly Installed
Start by ensuring that the water tank is correctly seated in the machine. An improperly placed tank can cause leaks or drips. Remove the water tank carefully, check for any cracks or damage, and then reinsert it firmly into its slot. Make sure it is securely clicked into place to prevent water from escaping during operation.

2. Check for Cracks or Damage in the Water Tank
Inspect the water tank thoroughly for cracks, chips, or damage. Even small fractures can lead to leaks. If you find any damage, replace the water tank with an original part or a compatible replacement to avoid further leaks and ensure proper water flow.
3. Examine Seals, Gaskets, and Connections
Leaking can often occur at the seals and gaskets around the water tank, brew group, or steam wand. Look for signs of wear, cracks, or misalignment. Replace any worn seals with genuine De’Longhi parts, such as the water filter or gaskets, to maintain a tight seal and prevent leaks.
4. Clear Mineral Buildup and Descale the Machine
Mineral deposits from hard water can block pipes and valves, leading to water overflow. Use a descaling solution like the De’Longhi EcoDecalk Descaler, following the manufacturer’s instructions. Regular descaling (every 2-3 months) helps maintain smooth water flow and prevents leaks caused by mineral buildup.
5. Inspect and Replace Worn Components
If leaks persist after cleaning and reassembly, inspect internal components such as valves, hoses, and the brew group. Look for signs of wear or damage. Replace worn parts with original De’Longhi accessories to ensure optimal functioning and prevent future leaks.
