3-Way Solenoid Valve Assembly
The 3-way solenoid valve is the primary failure point in the hydraulic circuit when flow to the group head is restricted despite pump activation. Mineral scale precipitates within the boiler and migrates to the valve, where it lodges in the micro-sized pilot orifice or prevents the plunger from retracting fully. Replacing the entire assembly ensures that the plunger seat, internal seals, and electromagnetic coil are all within factory specifications, restoring proper pressure relief and brew flow.
