🔧 Product Overview

The brew unit (infuser assembly) is responsible for piercing, sealing and extracting coffee from the Nespresso capsule during the brewing cycle.

It helps:

✔ Deliver proper brewing pressure

✔ Create consistent coffee extraction

✔ Prevent internal coffee leaks

✔ Support correct capsule piercing

✔ Improve coffee strength and flavour

✔ Restore original machine performance

As brew units wear over time, internal seals and piston components can deteriorate, causing coffee leaks, weak extraction and brewing faults.
