Brew Unit (Infuser) Assembly
The Brew Unit is the central reciprocating mechanism that compresses coffee. If the internal levers or piston become jammed due to coffee residue or lack of lubrication, the unit will fail to reach its limit switches during the homing sequence, causing the flashing alarm. Replacing the entire assembly ensures all mechanical pivot points and seals meet factory torque specifications.

Transmission Microswitch
The control board relies on physical contact switches at the top and bottom of the transmission rail to verify the infuser's position. If these switches suffer from mechanical fatigue or contact oxidation, the machine cannot confirm the infuser is 'present,' even if it is correctly inserted. This results in the flashing triangle lockout as a safety measure.

Infuser Piston O-Ring Kit
The infuser piston uses EPDM O-rings that expand and degrade over time due to thermal cycling and coffee acidity. Swollen or dry seals create excessive drag on the drive motor, preventing the transmission from completing its vertical travel and triggering the position-based alarm.
