This guide shows how to replace the power switch on a Bezzera Sole espresso machine. You will remove the switch retaining nut, disconnect the four wiring spade connectors (keeping the two blue wires on one side and the brown and black on the other), remove the old switch, install the new switch aligned to the flat spots in the front panel opening, tighten the retaining nut, and reconnect the wires.
