La Marzocco Linea PB 3 Group AV (Automatic) Espresso Machine

La Marzocco's Linea PB 3 Group is the professional barista’s benchmark. Engineered for high-volume cafés and precision-focused espresso programs, the Linea PB delivers advanced temperature stability, volumetric dosing, and performance reliability in a sleek stainless steel frame.

Refined by Piero Bambi, this 3-group espresso machine builds on the legacy of the Linea Classic with a new level of craftsmanship and programmable control — making it one of the most trusted machines in specialty coffee.

Key Features of the Linea PB 3 Group

To complement its stylistic updates, the Linea PB features improved component longevity and new electronics that give the barista control over functions directly from the machine interface – including boiler temperatures, brewing volume, hot water tap dose, and auto-backflush, among others.

• Dual boilers optimize espresso brewing and steam production for consistent coffee brewing and are designed for high volume output, while the Dual PID allows you to electronically control coffee and steam boiler temperatures.
• Saturated groups ensure unsurpassed thermal stability, shot after shot, and Piero Group Caps ensure water never leaves the coffee boiler during the brewing process, eliminating instability.
• Barista LED lights allow you to focus on your extraction and the cup.
• Ruby flow restrictors resist scale formation and erosion, extending the life and performance of your machine.
• Eco-mode saves energy: after extended idle periods, boiler temperatures reduce to lower set-points.
• Proprietary electronics drive intuitive programming and provide heads-up information and systems monitoring on a digital display; shot timers, flow pulse counter, USB firmware updates, boiler temperatures, and system alerts.
  

Which Model Is Right for You? (AV vs MP vs EE)

• AV (Auto Volumetric) – Best for busy cafés; programmable dosing for consistent output.
• MP (Mechanical Paddle) – Ideal for baristas who want full manual control and variable pre-infusion.
• EE (Semi-Automatic) – A great balance of control and speed with traditional push-button extraction.
