professional-grade espresso equipment,
built for the home

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.

performance at home – la marzocco technology and performance in an elegant, self-contained footprint.

Product Sheet

conical paddle

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.


Exposed Saturated Group
increased temperature stability, ergonomics and workspace visibility.

Dual Boiler System
separate boilers optimize espresso brewing and steam production.

Internal Pump
makes the GS3 ideal for the home.

Dual PID (coffee and steam)
allows you to electronically control coffee and steam boiler temperature.

Insulated Boilers
reduce energy consumption while contributing to temperature stability.

Ruby Flow Restrictors
synthetic ruby flow restrictors resist scale formation and erosion.

Pre-heating System
prior to entering into the coffee boiler, water is pre-heated – thus increasing productivity.



Stainless Steel Portafilters & precision baskets
for improved cup quality and consistency.

Digital Display
temperature display, shot timers, flow pulse counter and intuitive programming simplifies the adjustment of machine parameters.

Performance Touch Steam Wands
High performing steam wandsthat are cool to the touch.

Water Reservoir
an integrated 3.5 liter water tank makes plumbing optional.

Hot Water Economizer
fine tune the temperature of the hot water spout.
