Use a wrench to remove the boiler hose from the pressure release valve.

Remove the two slotted screws securing the pump brackets to the frame of the Barista.

The simple angled rubber pump brackets are designed to absorb vibration from the reciprocating pump.

Disconnect the two female AC power spade connectors from the pump and slip the thermal fuse out from its holder on the body of the pump.

The thermal fuse is a normally closed protective switch that opens the circuit once the pump has reached a critical temperature, thus shutting it down before the coil melts.
