What the Group Head Assy SES450 Does
The Group Head Assy SES450 is the brewing head assembly responsible for delivering hot water through the coffee puck under pressure to extract espresso. As the core mechanical unit of the brewing process, it houses the components that ensure water flow, pressure, and seal integrity during each shot.

- Water leaking around the group head during brewing
- Inconsistent pressure or uneven extraction
- Visible cracks, corrosion, or worn seating surfaces
- Difficulty locking the portafilter securely
Any of these signs may indicate the assembly needs replacing to restore proper brewing performance.
