How to Bleed the Group on the La Marzocco GS3

The group bleeding on a La Marzocco GS3 procedure should be done immediately after the boilers have been filled and prior to the machine warming up. Waiting for the machine to heat up may cause hot water to exit the bleeding screw and burn the user so it is very important to do while the machine is cold. Now that you have done that, now unplug the machine.1
