If you’ve been asking, "how to safely clean my La Marzocco KB90 group head" or struggling with older blind filters that cause messy and dangerous hot water splashback, this dedicated insert is the solution. Engineered specifically for the revolutionary KB90 straight-in portafilter system, this component is essential for performing a proper backflush cycle, which is critical for removing stale coffee oils and grounds buildup from the brew group. This part ensures that, as the backflush ends, water drains safely through the basket hole, effectively solving the common "problem of hot water spray during backflush" and maximizing barista safety.

Installation is simple: replace your standard filter basket with the F.3.131 Backflush Insert, dose the appropriate cleaning solution, and run your machine’s programmed backflush cycle (or run five seconds on and five seconds off ten times). By using the genuine KB90 Backflush Insert, you not only improve safety and cleanliness but also ensure consistent shot quality by guaranteeing that no residual oils contaminate the next espresso extraction.
