Step 2: Check and Replace the Water Filter
The De’Longhi Magnifica Evo uses a water filter to improve water quality and reduce mineral buildup. A clogged or expired filter can cause pressure issues and leaks.
- Remove the water filter from its compartment.
- Inspect it for signs of clogging or damage.
- If needed, replace it with a new De’Longhi Replacement Water Filter (ASIN: B00CXQ9GQ8).
- Reinstall the filter securely and fill the tank with fresh water.
Step 3: Descale Your Machine
Mineral deposits caused by hard water can block internal pathways and lead to leaks. Regular descaling is crucial for maintaining proper function.
Follow these steps for effective descaling:
- Use a descaling solution such as De’Longhi EcoDecalk (ASIN: B0021IOTTW or B008YETL18).
- Follow the manufacturer’s instructions to run the descaler through the machine’s brewing cycle.
- Rinse thoroughly by running clean water cycles afterward.
This process helps remove lime scale and prevents leaks caused by clogging.
Step 4: Inspect and Replace Seals and Gaskets
Over time, seals and gaskets may wear out, crack, or become loose, leading to leaks.
- Identify any visible damaged or worn seals around the water tank, brew group, or internal connections.
- Replace damaged seals with compatible parts. Consult the user manual or contact De’Longhi support for the correct replacements.
- Ensure all seals are fitted securely after replacement.
This step often resolves leaks originating from internal connections.
Step 5: Test the Machine and Monitor for Leaks
After completing the above steps, plug in your machine and turn it on.
Run a small water cycle without coffee to check for leaks. Observe all connections, the water tank, and internal components.
If leaks persist, revisit the steps or consider contacting professional repair services.
