Brew Group Maintenance & Seal Kit
The EPDM gaskets on the pistons swell over time due to thermal cycling and exposure to coffee acidity, increasing mechanical drag. This kit provides the necessary high-temperature O-rings and food-grade silicone lubricant to restore the fluid movement required for the motor to complete its timed rotation without stalling.

Brew Group Encoder
This component tracks the revolutions of the brew group's drive shaft; if the plastic clips securing it to the motor housing fracture, the encoder loses alignment. This results in missing pulse signals to the PCB, leading the machine to erroneously conclude the brew unit is jammed.
