Step 2: Inspect the Water Tank and Connections
- Remove the water tank carefully and check for cracks or damage.
- Ensure the tank is seated correctly and the valve is closed tightly.
- Look for any loose or damaged hoses or fittings inside the machine, especially around the water inlet and outlet areas.
Step 3: Check and Replace Seals and Gaskets
Worn or damaged seals are a common cause of leaks. Inspect all visible seals and gaskets, especially around the brew group and water tank connection. If you find any cracks or brittleness, replace them with compatible parts.
Step 4: Clean and Descale Your Machine
Mineral deposits can cause blockages and pressure issues that lead to leaks. Use a descaling solution like De’Longhi EcoDecalk Descaler following the instructions. Regular descaling helps maintain optimal performance and prevents leaks caused by buildup.
Step 5: Test the Machine After Repairs
Reassemble all parts securely, refill the water tank, and plug in the machine. Turn it on and run a short brew cycle without coffee to check if the leak persists. If leaks continue, further inspection or professional servicing may be required.
