Restore consistent dosing in your commercial grinder with the genuine Mazzer Upper Dosing Star (Part # M28300). Engineered as a precision replacement component, this dosing star is fully compatible with popular Mazzer models, including the Super Jolly, Kony, and Major V. This crucial part ensures that the correct volume of ground coffee is consistently swept from the dosing chamber into the portafilter, eliminating inconsistencies that can plague high-volume coffee operations. Its durable, high-quality construction is designed to withstand continuous commercial use, preventing the wear-and-tear failures common in non-OEM parts. If you are experiencing issues like an "inconsistent dose quantity" or "grinder dosing star sticking," replacing this worn or broken upper dosing star is the definitive solution to maintain accurate espresso preparation.

The key feature of the Mazzer M28300 is its precise rotational sweep, which ensures every turn of the dosing lever dispenses a perfectly leveled quantity of coffee, directly impacting the quality and repeatability of your espresso shots. A worn dosing star can lead to coffee spilling or incorrect dose weights, causing major workflow disruptions. By installing this genuine replacement, you benefit from consistent shot timing and reduced waste. Usage is straightforward for qualified technicians, integrating seamlessly into the existing dosing mechanism of your Mazzer grinder.

Ensure your Mazzer Super Jolly, Kony, or Major V maintains its factory performance with this essential component. Stop struggling with a "Mazzer doser not sweeping clean" or "coffee grounds stuck in doser" and upgrade to the M28300. This is the optimal, long-term fix for maximizing your machine's uptime and guaranteeing consistent espresso quality across all your servings.
