Group Head Gasket (Steam Ring)
The group head gasket creates the airtight seal between the portafilter and the brew head. When this seal degrades due to heat exposure, pressurized water escapes around the edges of the basket instead of being forced through the coffee grounds, resulting in a low reading on the manometer. Replacing this restores the hydraulic integrity of the extraction chamber.

Ulka EAX5 Vibration Pump
The vibration pump utilizes an electromagnetic piston to create pressure. Over time, internal springs lose tension or the piston seal wears down, preventing the pump from overcoming the resistance of the coffee puck or the 9-bar Over-Pressure Valve setting. This results in the pump stalling at a lower pressure threshold regardless of grind fineness.

Brew Head O-Ring Service Kit
Internal leaks at the thermocoil junctions or the three-way solenoid valve reduce the effective flow rate to the group head. Small ruptures in these high-temperature silicone O-rings allow pressurized water to divert into the drip tray or internal chassis, bleeding off the pressure required for a proper extraction.
