Step 2: Check the Water Tank and Hoses
- Remove the water tank and inspect it for cracks or warping. Ensure the water tank is seated correctly when reinstalled.
- Examine the connecting hoses for visible cracks, disconnections, or leaks. Tighten any loose fittings.
- Refill the tank and carefully observe if water leaks when the machine is powered on.
Step 3: Inspect Seals and Gaskets
Water leaks often originate from worn or damaged seals. Check all accessible gaskets, particularly around the brew unit and water inlet. Look for cracks, tears, or mineral buildup.
If seals are damaged, they should be replaced to prevent further leaks and maintain proper pressure.
Step 4: Clean and Descale the Machine
Mineral deposits can cause blockages, resulting in pressure buildup and leaks. Use a descaling solution such as the De’Longhi EcoDecalk Descaler, following the manufacturer’s instructions. Regular descaling (every 2-3 months) keeps internal components clear.
Clean the drip tray, water tank, and removable parts thoroughly to prevent debris accumulation that could cause leaks.
Step 5: Test After Repairs
Once all parts are inspected, cleaned, and reassembled, plug in the machine. Run a short brew cycle without coffee to observe if the leak persists. Monitor the water tank and internal parts for any signs of leakage.
If leaks continue, consider replacing worn components or consulting a professional repair service.
Tips and Warnings for Safe Troubleshooting
- Always unplug your machine before opening or inspecting internal parts.
- Use only recommended replacement parts and accessories.
- Follow manufacturer instructions for descaling and maintenance.
- Be cautious of hot water and steam during inspection.
- If unsure about repairs, contact a certified technician to avoid voiding your warranty or causing further damage.
