La Marzocco GS3: Replacing the FlowmeterUpdated 5 months ago

Before doing this we recommend unplugging the machine and allowing it to fully cool off.

Tools required:

• 13mm socket wrench
• 14mm wrench
• 17mm wrench
• adjustable wrench

First, remove the right side panel.

When finished tighten down all tubes and test for flow, leaks and error code.
