Understanding the Causes of Grinder Clogs
Grinder clogs in Breville espresso machines typically result from a combination of factors. Coffee oils and residues can accumulate over time, especially if the grinder isn’t cleaned regularly. Additionally, using a grind that’s too fine can increase resistance and cause grounds to jam between the burrs. Debris or damaged beans may also introduce foreign particles that block the grinding mechanism. Recognizing these causes helps in both prevention and targeted fixing, ensuring your machine remains efficient and reliable.
