3-Way Solenoid Valve Assembly
This valve manages the flow of pressurized water to the group head and vents excess pressure to the drip tray. If scale debris or chemical degradation affects the internal rubber plunger, the valve fails to seat properly, causing pressurized water to bypass the brew path and leak into the expansion circuit, resulting in low gauge readings.

54mm Silicone Steam Ring (Group Head Gasket)
The steam ring creates the critical hermetic seal between the portafilter and the group head. Thermal fatigue eventually hardens the silicone elastomer, leading to micro-leaks that prevent the system from building the backpressure required for espresso extraction, directly causing low or zero movement on the pressure gauge.

Ulka EAX5 Vibratory Pump
The vibratory pump is the mechanical heart of the machine's pressure generation. Wear on the internal piston seals or the compression spring reduces the pump's ability to maintain high-pressure flow against the resistance of the coffee puck, leading to a steady decline in maximum achievable BAR pressure over time.
