Step 2: Examine the Water Tank and Connections
- Remove the water tank carefully and inspect it for cracks or damage.
- Ensure the tank is properly seated and locks securely into place.
- Check the rubber gasket or seal around the tank for wear or misalignment.
Step 3: Inspect Internal Hoses and Fittings
Open the machine’s access panels if possible, and look for loose or damaged hoses. Tighten any fittings that appear loose, and replace any cracked or brittle hoses.
Step 4: Check the Water Filter and Descale if Needed
A clogged water filter or mineral buildup can cause pressure issues leading to leaks. Consider replacing the water filter with a compatible model and descaling your machine using a descaler like the De’Longhi EcoDecalk if buildup is suspected.
Step 5: Test the Machine
Once you’ve inspected and addressed potential issues, reassemble the machine, refill the water tank, and plug it in. Run a test brew to see if the leak persists. If water leaks again, further inspection or professional repair may be necessary.
