Learn how to properly backflush and clean the brewing system of your F1 series espresso machine for better performance and longer life.

If you’ve ever pulled a shot and noticed your espresso tasting off—bitter, soapy, or just plain dirty—it might not be the beans. More likely, it’s buildup inside your machine’s brewing system. Coffee oils, old grounds, and mineral deposits can accumulate over time, especially around the group head, portafilter gasket, and dispersion screen. Regular cleaning isn’t optional—it’s essential for consistent shots. Here’s how to clean the brewing system on an F1 series espresso machine, step by step.
