To operate this La Marzocco espresso machine, employees will simply need to press buttons or turn a knob, which requires limited training. However, learning the nuances of proper brewing, steaming, and frothing will necessitate more in depth training and practice regimens. Users can be directed to the following articles for detailed descriptions of the brewing and frothing processes, but hands-on training is necessary for the best results.

Feature Details

Steam Wand

The La Marzocco GB/5’s stainless steel steam wands are ball joint-mounted, so they move in any direction for easy access with large frothing pitchers and cups. The wands also have the option of being replaced with an auto-frothier for even easier use.

PID Control

To allow you to control the temperature of the brewing boiler down to the degree, the GB/5 features Proportional Integrated Derivative (PID) temperature control. This technology senses temperature changes in the boiler, and pulses the heating element to maintain the set temperature within ½oC at all times. With PID technology, you get unbeatable temperature stability, and you can customize a brewing temperature for each type of coffee you use, for the best flavor possible from every roast.

Programming Options

The GB/5 automatic features 4 programmable buttons for each brew group to provide customized brewing options to perfectly match your business needs. With variable temperature and water volume amounts for single and double shots, the GB/5 can be programmed to provide fast and consistent pulls during your busiest hours. Plus, the built-in hot water dispenser features a tea button that can be programmed as well, so tea drinkers can look forward to the same consistent performance that all of your customers expect.

Saturated Brew Groups

For excellent temperature stability, each brew group in the La Marzocco GB/5 espresso coffee maker is welded onto the brewing boiler. This allows a large mass of hot water to spread from the boiler to the brew groups and maintain a stable temperature between the components.

Back Up Devices

To decrease downtime for servicing, this La Marzocco espresso machine has back-up devices that allow you to keep brewing even while a technician is testing or servicing many of the machine’s primary functions.

Stainless Steel Cup Warmer

All of our La Marzocco espresso machines feature extra-large cup warmers to ensure you'll always have plenty of preheated cups ready to brew when you are.

Electrical Options

Accommodating any environment, the GB/5 is available in a 200v (1 or 3 phase), 220v (1 or 3 phase), or 380v (3 phase) model. You can also choose between standard wattage and high wattage elements.

Prior to installation, you will need to submit the following electrical and plumbing requirements (both found in the Installation Guidelines Diagram) to a general contractor, electrician, or plumber as well as your code enforcement officer to ensure the compliance of your facility with the needs of this espresso coffee maker.
