Step 1: Unplug and Prepare Your Machine
Before starting any troubleshooting, ensure your De’Longhi espresso machine is unplugged and cooled down. Remove any water containers, drip trays, or removable parts. This prevents accidental spills or electrical hazards during inspection. Have a clean cloth ready to wipe up any water leaks, and gather tools like a screwdriver, replacement seals, and water filters if needed.

Step 2: Identify the Leak Source
- Check the drip tray and water containers for overflowing or cracks.
- Inspect the area around the water reservoir for signs of water dripping or pooling.
- Look at the brew head, steam wand, and internal tubing for any visible leaks or moisture.
- Examine seals and gaskets around the water reservoir and internal components for wear or damage.
Knowing exactly where the water leaks from helps you target the specific cause, whether it’s a seal failure, cracked container, or clogged internal part.
Step 3: Inspect and Replace Seals and Gaskets
Worn or damaged seals and gaskets are common reasons for water leaks in espresso machines. Carefully remove the water reservoir and inspect the seals around the edges. Look for cracks, deformation, or mineral buildup that may prevent a proper seal.
If you find any damage, replace the seals with genuine De’Longhi replacement parts. This step often resolves leaks originating from the water reservoir connection or internal water pathways.
Step 4: Check and Replace the Water Filter
If your machine is equipped with a water filter, such as the De’Longhi Replacement Water Filter (asin=B00CXQ9GQ8), ensure it is correctly installed and not clogged. A clogged or improperly fitted filter can cause water to leak or spill during operation. Remove the filter, rinse or replace it if necessary, and ensure it fits snugly into the water reservoir.
Regularly replacing the water filter helps maintain water quality and prevents internal blockages that can lead to leaks.
Step 5: Clean and Descale Your Machine
Mineral deposits from hard water can cause internal blockages and leaks. Use a descaling solution like the De’Longhi EcoDecalk Descaler (asin=B0021IOTTW or B008YETL18), following the manufacturer’s instructions. Regular descaling (every 2-3 months) keeps internal pipes clear and prevents leaks caused by mineral buildup.
Ensure you run a full descaling cycle and rinse your machine thoroughly afterward to remove any residue.
Additional Tips & Warnings
- Always unplug the machine before inspecting or replacing parts.
- Use only genuine De’Longhi replacement parts to ensure proper fit and function.
- Handle internal components carefully to avoid damage.
- If the leak persists after replacing seals and cleaning, consult a professional technician or contact De’Longhi customer support.
