Italian Craft. Home Precision. Professional Power.
Handmade in Florence, Italy, the La Marzocco GS3 represents the gold standard for home espresso machines—combining the brand’s legendary dual-boiler technology, saturated group system, and PID precision in a form refined for everyday use. Engineered for performance and reliability, it brings the same temperature stability and control found in La Marzocco’s commercial machines into your kitchen, office, or mobile café.
Equipped with a 3.5L steam boiler and 1.5L coffee boiler, the GS3 delivers effortless power and consistency, even under heavy use. The built-in water reservoir makes plumbing optional, transforming this into a portable espresso station that performs flawlessly on standard 110V power. From its Performance Touch steam wand to its dual PID temperature system, every element is designed to give you total command over your espresso experience—without compromise.
This is La Marzocco performance, distilled into a self-contained masterpiece.
Why It Stands Out
• Dual-Boiler System — Dedicated boilers for brewing and steaming maintain perfect thermal balance and eliminate recovery time.
• PID Precision Control — Independently control both coffee and steam boiler temperatures for unmatched stability.
• Performance Touch Steam Wand — Cool-touch, high-output wand provides smooth, powerful milk texturing.
• Auto-Volumetric Dosing — Program exact shot volumes for repeatable perfection, shot after shot.
• Thermal Stability System — Water passes through key components before extraction, ensuring perfect brew temperature.
• Digital Interface — Simple, intuitive display for shot timers, temperature control, and system settings.
• Optional Plumbing — Use the integrated 3.5L water reservoir for portability, or plumb directly for continuous service.
• Ruby Flow Restrictors — Synthetic ruby restrictors reduce scale buildup and extend internal component life.
• Internal Rotary Pump — Self-contained, quiet, and consistent in pressure delivery.

- Grind and dose your espresso, then tamp evenly.
- Lock in the portafilter and begin extraction—monitoring flow time for balance.
- Use the steam wand to texture milk as needed, then purge and clean immediately after use.
Care & Maintenance
Care & Maintenance
- Backflush the group head daily with fresh water; use espresso cleaner weekly.
- Wipe steam wands and portafilters after every session.
- Descale every 3–6 months depending on water hardness.
