Product Description Technically, the La Marzocco GS/3 is a commercial machine, ready for use in a coffee shop or kiosk but we are also selling it for the home. With dual stainless steel boilers for simultaneous brewing and steaming, a 118 oz water reservoir, separate stainless steel hot water and steam wands, a multifunction backlit keypad and easy to read digital display, programmable water volumes, adjustable temperature control and more, we figured that this machine was too good to hide from a retail audience. If youâ??re ready to blur the line between â??consumerâ?? and â??professional,â?? or if you think the line never really existed in the first place, then youâ??re ready to take a closer look at the respected and reputable La Marzocco GS/3. This machine has a 13 month warranty. Features & Benefits: Coffee Design To the left of the brew group are two pressure gauges â?? the far left pressure gauge shows the pressure in the brew boiler, and the gauge closer to the brew group shows the pressure in the steam boiler. Above these gauges is the steam wand, and below them is the steam activation lever. To the right of the brew group is the digital display with clock and below the display is the keypad. This is also where you find the hot water dispenser and hot water lever. They keypad has icons, so you can remember which button does which. From left to right, they stand for espresso, double espresso, coffee, double coffee, programming and tea. When in programming mode, the espresso and double espresso buttons stand for a down arrow and an up arrow, respectively. The coffee button is used to access certain menus, the double coffee button has no programming function, and the tea button is used to turn the GS/3 on and off. Brewing The machine is heated to proper brewing temperature when the keypad buttons are backlit. Before brewing, itâ??s a good idea to run some hot water through the portafilter. This warms the portafilter to brewing temperature, so your espresso is brewed at a consistent temperature. Add grounds to the portafilter, insert the portafilter into the group head, and press the button corresponding to your preferred drink â?? espresso, double espresso, coffee, or double coffee. The machine will automatically dispense a set volume of water through the grounds. When brewing, the brew boiler pressure gauge should read about 9 bars.
