All about the La Marzocco GB5 S – Shared coffee boiler
The GB5 S brews from one large saturated coffee boiler shared by all groups: 3.4 liters on the 2-group, 5 liters on the 3-group. Every group runs at the same temperature, which suits a bar built around one house espresso. A built-in water sensor measures the hardness and conductivity of the incoming water, and Piero group caps, dual PID and 24V electronics complete a machine built for a busy specialty bar.
Which La Marzocco fits your needs?
The GB5 S comes with 2 or 3 groups, as AV (programmable doses) or ABR (scales in the drip tray). Pro Touch steam wands, high legs, a cup warmer and RAL colors are special-order options. Tell us your peak volume and bar layout and we help you choose.

Key features
Water sensor
Measures conductivity and hardness of the incoming water. Check water quality and filter performance without extra test tools.
Saturated groups and Piero group caps
Stable brew temperature shot after shot. The Piero caps have a re-engineered internal water path and flow-meter position.
Dual PID, insulated boilers
Set coffee and steam boiler temperature separately. Insulated boilers use less energy.
AV or ABR
AV stops each shot at a programmed volume. ABR weighs the shot with scales in the drip tray and uses Drip Prediction to stop on target.
Barista lights and eco mode
Dimmable LED lights in three levels for Eco, On and Brewing. Eco mode puts the machine in standby on a schedule.
Built for service
Easy-rebuild steam valve, serviced from the front. 24V electronics, USB port for firmware updates, and La Marzocco Pro app for doses, coffee boiler temperature and usage statistics.

Frequently asked questions
GB5 S or GB5 X?
The GB5 S shares its coffee boiler between the groups. The GB5 X has a separate coffee boiler per group, so each group can run its own temperature, and Pro Touch steam wands as standard.
Which electrical connection does it need?
La Marzocco builds it for 200 V single phase, 220 V single or three phase and 380 V three phase. Maximum power is 5,445 W (2 groups) or 7,240 W (3 groups). Have your electrician check the connection before installation.
What does the water sensor measure?
Conductivity and hardness of the water entering the machine, so you see when your water treatment needs attention.
AV or ABR?
AV stops the shot at a programmed volume. ABR has scales in the drip tray and stops on weight; useful when several baristas work the bar.
Which sizes can I order on this page?
This page lists the GB5 S with 2 or 3 groups. Options such as legs, color, scales (ABR) or another voltage go through a quote.
Can it run its own cleaning cycle?
Yes. On the GB5 S the barista sets boiler temperature, doses, hot water and automatic cleaning cycles in the electronics.
What does OR include with the machine?
12 kg of OR specialty coffee for espresso, a Full Barista Training for two people from your team at OR Academy, and full installation of the machine with OR coffee beans.
