The machine makes use of the PID (Proportional, Integral, Derivative) temperature control system for the coffee boiler. The temperature can be adjusted by the user in a range from 85C ° to 100C°.
The La Marzocco GS3 has 2 programming menus – “machine on” programming and “machine off” programming. “Machine on” programming controls your preferences for espresso, such as the steaming and brewing temperature, digital clock adjustments, water volume, automatic on/off and more. To enter in the “machine on” programming mode, press and hold the programming button while the GS/3 is turned on. “Machine off” programming controls the actual GS/3’s performance and it’s not recommended that you adjust these settings, such as language, boiler temperatures, temperature measurement units, water filter alarm, and more. To enter into the “machine off” programming mode, turn the machine off and then press and hold the programming button.
The La Marzocco GS3 features a digital display with clock and below the display is the user friendly keypad with icons. You will find the hot water dispenser and hot water lever close to the keypad. The keypad icons, from left to right, 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 GS3 on and off.
The La Marzocco GS3 features double boilers that allow the user to operate the coffee boiler independently from the steam boiler, reducing the consumption of energy. A 2-boiler system lets you go right from brewing to steaming with no down time, so you can make cappuccinos, lattes, and other milk drinks instantly.
Saturated Brewing Group
The La Marzocco GS3’s saturated group results in more stable brew temperature. Because the La Marzocco group is integrated with the brew boiler (and thus "saturated" by the water within that boiler), there are fewer issues with the group cooling when idle, as one commonly sees in other groups.
To steam milk, what you need to do is press the steam activation lever and the ‘cool touch’ steam wand will dispense sufficient steam for frothing cappuccinos or lattes. The machine features a boiler dedicated for steaming, allowing you to brew and steam at the same time. To prevent milk residue buildup, do not forget to run a little water through the steam wand once you are done and then wipe off the steam wand with a damp cloth.
Press the tea button on the control panel to get hot water for Americanos, teas or instant soups. Hot water will begin to flow from the hot water dispenser on the right side of the machine.
Hot Water Reservoir
The La Marzocco features a large water reservoir which holds about 3.5 liters of water. The model is plumbable, so you can connect it straight to your home’s water supply. To keep your coffee tasting fresh, remember to rinse and clean the water tank with warm soapy water or in the dishwasher about once a month.
Built-In Cup Warmer
Espresso tastes its best when it is brewed into a pre-heated cup – this preserves the temperature and the crema. The machine has a built-in cup warmer which is heated using residual heat from the boiler.
The La Marzocco GS3 comes with a detailed user manual, single spout portafilter, double spout portafilter, blind filter basket, single shot filter basket, double shot filter basket, plumbing kit, tamper and cleaning solution.
