What Causes Capsule Not Piercing?
DeLonghi super-automatics feature adjustable burr grinders and self-cleaning brew groups.
- Maintenance neglect: Irregular descaling and cleaning are the top causes.
- Component wear: Seals, gaskets, and pumps degrade with use.
- Water quality: Hard water causes scale that blocks sensors and heating elements.

Step-by-Step Fix
Follow these steps specifically for Delonghi machines:
- Check capsule holder alignment on Delonghi. It should seat firmly until it clicks.
- Inspect piercing needles for clogs. Clean with a thin needle or paperclip.
