The hot water switch activates the solenoid or valve that dispenses hot water from the machine’s boiler. When pressed or toggled, it completes an electrical circuit that opens the hot water circuit, allowing hot water to flow from the group or dedicated hot water wand. A failed switch can prevent hot water dispensing entirely or cause continuous flow. Is this compatible with my Wega machine?
