3-Way Solenoid Valve Assembly
The valve body and internal plunger are prone to calcium carbonate buildup which physically obstructs the travel of the piston. Replacing the entire assembly ensures that any pitting in the valve seat or degradation of the internal seals is addressed, restoring the pressure-relief function during the exhaust phase of the brew cycle.

Solenoid Coil
The solenoid coil is an inductor that converts electrical energy into a magnetic field; constant heat exposure causes the internal insulation to fail, leading to an electrical short or open circuit. This prevents the mechanical plunger from actuating even when the control board sends the correct signal.

Solenoid Plunger Repair Kit
This kit replaces the moving internal piston and spring which are the primary victims of mechanical wear and scale-induced friction. It is the most granular fix for a 'weeping' group head where the valve fails to fully seal due to spring fatigue or seal deformation.
