Step 1: Turn Off and Unplug the Machine
Before inspecting or attempting repairs, ensure your De’Longhi espresso machine is turned off and unplugged from the power outlet. This prevents electrical hazards and allows the machine to cool down, especially if it has been used recently. Wait at least 10-15 minutes to let internal components cool before proceeding.

Step 2: Check the Water Reservoir and Its Seal
- Remove the water reservoir carefully from the machine. Inspect the edges for cracks or damage.
- Examine the rubber gasket or seal around the reservoir for signs of wear, cracks, or dirt buildup.
- If the seal appears damaged or dirty, clean it with a damp cloth or replace the water filter (if used) to ensure a tight fit.
- Reinsert the reservoir securely, making sure it clicks into place and is properly aligned.
Step 3: Examine External and Internal Hoses
- Open the access panels or remove the side panels if your model allows. Use a screwdriver if necessary, following the user manual.
- Look for any cracked, loose, or disconnected hoses—especially those connected to the water inlet, steam wand, or internal valves.
- Check for water droplets or mineral buildup on hoses and fittings.
- If you find damaged hoses or loose fittings, tighten or replace them carefully.
Step 4: Inspect the Gaskets, Seals, and Valves
Leaking often occurs due to worn or damaged gaskets or seals. Focus on the areas around the brew group, steam wand, and water inlet valve. Replace any gaskets or seals that are cracked, hardened, or deformed. Refer to your machine’s manual for specific part numbers and replacement instructions.
Step 5: Descale Your Machine
Limescale buildup can cause internal blockages and leaks. Use a descaling solution compatible with De’Longhi machines, such as the EcoDecalk Descaler, following the manufacturer’s instructions. Regular descaling (every 2-3 months) maintains internal integrity and prevents leaks caused by mineral deposits.
Tips and Warnings for Safe Repair
- Always unplug the machine before performing any maintenance or repairs.
- Handle internal components gently to avoid further damage.
- If unsure about replacing internal parts, consult a professional technician.
- Use genuine replacement parts for gaskets, hoses, and filters to ensure proper fit and function.
- Follow the manufacturer’s instructions closely to avoid voiding your warranty.
