2. Check the Water Tank and Its Seal
- Remove the water tank carefully from the machine.
- Inspect the tank for cracks or damage. Replace if any cracks are found.
- Ensure the tank is seated properly when reinserting, with the seal fitting snugly to prevent leaks.
If the seal is worn or damaged, replacing the water tank or seal may be necessary.
3. Inspect Water Connections and Hoses
- Check all visible water hoses and connections for looseness or cracks.
- Tighten any loose fittings gently without over-tightening to avoid damage.
- If you notice damaged hoses, replace them with compatible parts.
This is especially common around the internal water pathways and fittings.
4. Clean and Descale Your Machine
Mineral deposits can cause internal blockages and leaks. Use a descaling solution like De’Longhi EcoDecalk Descaler to clean the machine regularly, following the manufacturer’s instructions. This helps maintain proper water flow and prevents leaks caused by buildup.
5. Reassemble and Test
After inspection and cleaning, carefully reassemble all parts. Fill the water tank, turn on the machine, and run a test cycle without coffee to check for leaks. Observe if the leak persists and note the source if it does.
