Basic Cleaning & Descaling
- Turn off and unplug the machine before maintenance.
- Remove the bean hopper and clean it thoroughly with a dry cloth.
- Use a soft brush to clear any coffee grounds or debris from the burrs.
- Descale the machine using a recommended descaling solution like the EcoDecalk, following product instructions.
Adjust the Grind Settings
In my testing, overly fine grind settings can cause the grinder to strain and produce noise. Try increasing the grind size slightly, then test the machine.
Use the machine’s control panel to select a coarser setting and run a test brew to check if noise diminishes.
Check for Worn or Damaged Parts
- Inspect the burrs for signs of wear or damage. Worn burrs can cause grinding noise and inconsistent coffee.
- Replace burrs if they appear dull or chipped—refer to the user manual or contact De’Longhi support.
- Ensure all screws and components are securely fastened.
Prevent Future Noise & Maintain Your Machine
- Clean the grinder regularly, ideally after every few uses.
- Use fresh, high-quality beans to reduce strain on the grinder.
- Follow a descaling schedule to prevent mineral buildup.
