The La Marzocco engineering group set out to take the most advanced La Marzocco technology and translate it for a home espresso machine. The GS3 features the thermal stability system used in the La Marzocco Strada, including a preheating system, digital PID controller, saturated groups, a dual-boiler system, and digital display. These features make for a luxury espresso preparation platform: everything you could hope for as someone who wants to enjoy the best-quality espresso at home. All that’s left for you to do is to grind, dose, and tamp.

This new conical valve system assures progressive control of water flow and pressure via an internal orifice, before applying full pressure. The paddle valve controls pre-infusion while the volumetric pump is working at full pressure, allowing the barista to perform pre-infusion on one group while the other is extracting coffee. This dynamic system allows the barista to reduce channeling for a more balanced extraction. 

Available in automatic (AV) and mechanical paddle (MP) versions. 

Features:

• Exposed saturated group for increased temperature stability, ergonomics and workspace visibility
• Dual boiler system optimises espresso brewing and steam production
• Internal pump making the GS3 ideal for the home
• Dual PID (coffee and team) allows you to electronically control coffee and steam boiler temperature
• Insulated boilers reduce energy consumption while contributing to temperature stability
• Synthetic ruby flow restrictors resist scale formation and erosion
• Pre-heating water system increases productivity
• Stainless steel portafilters and precision baskets for improved cup quality and consistency
• Digital display with intuitive programming for temperature, shot timers and flow pulse counter 
• High performing steam wands that are cool to the touch
• Integrated 3.5 litre water reservoir makes plumbing optional
• Hot water economiser
