Typically follows a Live (Brown), Neutral (Blue), and Earth (Green/Yellow) color code.
A: No. The 110V diagram often omits the thermal fuse and shows a different boiler terminal arrangement. Use only 240V-specific guides. Gaggia Classic Wiring Diagram 240v
Features a 3-way solenoid valve and standard rocker switches. You can find official technical schematics in the Gaggia Classic Wiring Diagram PDF .
