Step 1: Unplug and Prepare the Machine

Step 2: Empty and Inspect the Water Tank

  • Take out the water tank completely and examine it for any cracks, holes, or damage. If you find any, replacing the tank is necessary.
  • Check if the tank’s gasket or seal is properly seated and in good condition. A worn or misaligned gasket can cause leaks.

Step 3: Examine the Hoses and Connections

  • Inspect all visible hoses, especially those connected to the water tank and internal components. Look for cracks, loose fittings, or blockages.
  • If hoses are removable, detach and clean them. Reattach securely, ensuring all fittings are tight but not over-tightened.

Step 4: Check and Replace the Water Filter

If your machine uses a water filter (such as the De’Longhi Replacement Water Filter), ensure it’s correctly installed and not clogged. A clogged filter can cause pressure issues leading to leaks. Consider replacing it with a new filter if necessary.

Step 5: Perform Descaling

Limescale buildup can cause internal blockages and pressure imbalances. Use a descaling solution like the De’Longhi EcoDecalk Descaler to clean internal components. Follow the manufacturer instructions carefully to avoid damage.

Tips and Warnings for Safe Troubleshooting

  • Always unplug the machine before inspecting or performing maintenance.
  • Use only manufacturer-recommended parts and accessories to avoid voiding the warranty.
  • If you notice significant damage, cracks, or persistent leaks after troubleshooting, contact professional service or De’Longhi customer support.
