When to replace your grinder burrs: signs and service intervals

This guide is the step-by-step Coffee Parts walkthrough covering When to replace your grinder burrs: signs and service intervals. It covers the technique in detail with the practical specifics that matter — equipment required, the sequence of steps, the common mistakes to avoid, and the small details that separate a result that works from one that doesn't. The article reflects Coffee Parts' practical experience helping home users solve the same problem dozens of times — the patterns are surprisingly consistent across the customers we work with, and the technique stack is generally simpler than most online content suggests once you cut out the noise. Where cleaning chemistry is involved, the guide uses Cafetto products throughout — that's the brand Coffee Parts technicians use on the workshop bench, formulated specifically for espresso equipment and safe across the materials home machines use. Where parts are involved, the article cross-sells the relevant Coffee Parts inventory, and where there's a deeper sub-topic worth exploring it links to other guides in the Maintenance & Repair pillar. The article is part of the wider Coffee Parts knowledge hub — 99 answers since 1999 — and links back to the cornerstone pillar guide for readers who want the wider framework.
