What Causes Capsule Not Piercing?
Keurig machines rely on K-Cup puncture needles and water flow sensors that are prone to clogging.
- 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.
