Restore the flawless dosing precision of your Mazzer Vulcano espresso grinder with the genuine Vulcano Dosing System Pressing Spring (Part # M.1.247). This small but critical OEM replacement component is engineered to maintain the calibrated tension essential for the smooth, precise return action of the dosing lever, ensuring consistent and predictable ground coffee delivery every time. If you notice your dosing lever feeling sluggish or failing to return properly—a common issue when a spring wears out or loses tension—this replacement is the definitive solution. The Vulcano Dosing System Pressing Spring is built with high-quality, durable steel to withstand repetitive commercial use, guaranteeing maximum longevity and eliminating frustrating inconsistencies in your workflow.

With a simple installation, this pressing spring restores factory performance, resulting in faster cycling, reliable dose cuts, and improved efficiency in high-volume settings. The precise specifications (Part # M.1.247) guarantee perfect compatibility and function within your Vulcano's dosing mechanism.

Don't let a minor component compromise your grinding consistency. For commercial cafes seeking to "fix a sticky Vulcano doser," the Vulcano Dosing System Pressing Spring (M.1.247) is an essential, low-cost preventative maintenance item. Invest in this authentic OEM part from Kaldi.com to ensure reliable spring-back action, maintain precise mechanical control over your dosing, and preserve the long-term performance of your Mazzer Vulcano grinder, preventing future "dosing system failures."
