Step 1: Turn Off and Unplug Your Machine

Before inspecting or working on your espresso machine, ensure it is turned off and unplugged from the power source. This prevents electrical hazards and accidental activation during maintenance. Allow the machine to cool down if it was recently used, especially around the brewing area and water tank.

Step 2: Empty and Inspect the Water Tank

  1. Remove the water tank carefully from the machine.
  2. Check for cracks or damage in the tank that could cause leaks.
  3. Ensure the tank’s seal and gasket are intact and properly seated.
  4. If any damage is found, replace the water tank or gasket accordingly.

Sometimes, a loose or improperly seated water tank causes leaks during operation. Reinstall it firmly, ensuring it clicks into place securely.

Step 3: Check Internal and External Connections

  • Inspect all visible water lines and fittings for looseness or damage.
  • Gently tighten any loose fittings using the appropriate tools, being careful not to overtighten, which could cause damage.
  • Pay particular attention to the connection points around the water inlet and outlet valves.

If you notice any cracked or worn fittings, consider replacing them with genuine parts recommended for your model.

Step 4: Clean and Descale the Machine

Mineral buildup can cause internal blockages and leaks. Use a descaling solution like the De’Longhi EcoDecalk Descaler, following the instructions on the package. Regular descaling (at least every 2-3 months) helps maintain proper water flow and prevents leaks caused by scale deposits.

Ensure you flush the system thoroughly afterward to remove any residue.

Step 5: Examine and Replace Worn Seals or Gaskets

Over time, seals and gaskets can become brittle or damaged, leading to leaks. Locate seals around the water tank, brew group, and internal connections. If you notice cracking, hardening, or water seeping from these parts, replace them with authentic De’Longhi parts.

Always ensure the replacements are correctly installed and seated to prevent future leaks.
