Step 2: Check the Water Reservoir and Connections
Remove the water reservoir and inspect the connection points and the reservoir itself for cracks or damage. Ensure it’s seated properly when replaced. A loose or cracked water tank can cause leaks.
While the reservoir is out, examine the water inlet valves for blockage or damage. Clean any mineral deposits that might obstruct water flow.
Step 3: Inspect and Replace Seals and Gaskets
Leaking often results from worn or damaged seals or gaskets. Locate the seals around the water inlet, brew group, and other accessible areas.
If you notice cracks, deformation, or mineral buildup, replace these parts. Use the manufacturer’s recommended seals for a proper fit and durability.
Step 4: Clean the Water System and Descale
Mineral deposits can cause blockages, pressure issues, and leaks. Use a descaling solution such as De’Longhi EcoDecalk Descaler following the product instructions.
Regular descaling (every 2-3 months depending on usage) helps prevent leaks caused by limescale buildup and maintains optimal performance.
Step 5: Reassemble and Test
After inspecting, cleaning, and replacing necessary parts, reassemble the machine carefully. Make sure all components are securely in place.
Fill the water reservoir, plug in the machine, and run a test brew without coffee to check for leaks. Observe all connections and internal components closely.
Tips and Warnings
- Use genuine replacement parts: Always opt for manufacturer-recommended seals and gaskets to ensure proper fit and function.
- Maintain regular descaling: Prevent mineral buildup that can cause internal pressure and leaks.
- Handle parts carefully: Avoid forcing or damaging components during inspection or replacement.
- Safety first: Always unplug the machine before performing any maintenance or repairs.
- Consult professional help: If leaks persist despite troubleshooting, contact authorized service centers for assistance.
