Features & Functionality of the La Marzocco GS/3 Espresso Machine

    • Large Internal Reservoir: 3.5 liter reservoir loads from the bottom, resting behind the drip tray, and features an opening for easy refill without removing the entire unit.

    • Convertible Water Source: Use the internal reservoir or set the machine up to directly connect to your location's plumbing.

    • Sophisticated PID Control: Tailoring your brew temperature to achieve the best extract is simple with this digital-displayed PID that utilizes multifunction keypads.

    • No Burn Wands: Stainless steel hot water and steam wands feature 'Cool Touch' technology, decreasing the  burn factor.

    • Internal Volumetric Pump: Also known as a rotary vane pump, this quieter pump is designed to maintain a specific volume capacity that is consistently maintained.

    • Saturated Brew Group: Water is distributed evenly across the brew group, resulting in an more consistent pre-infusion and extraction rate, reducing the possibility of channeling.

    • Hot Water Tweaking: Easily select how much cold water you want incorporated into the hot water pulled from the boiler, tailoring your teas or Americanos to your preferred temperature.

    • Monster Drip Tray: If you don't setup the draining kit, no worries -- the huge capacity of the GS/3's drip tray means you won't have to empty it very often.
