Before you order — safety firstDisconnect the machine from power and let it cool fully before opening the case. Thermostats sit on the 230V boiler circuit. Verify with a multimeter that no terminals are live before removing wires. If you are not comfortable working with mains electricity, ask a qualified person to fit this kit for you.

Two temperatures. Two distinct jobs.
The kit pairs a 107°C brew thermostat with a 145°C steam thermostat for the two temperature circuits in a compatible Gaggia machine.
Made for an M4 threaded fitting.
Both thermostats use an M4 mounting thread. Compare the thread and mounting position on your existing thermostat before ordering.
A clean thermal connection matters.
The included thermal grease fills small surface gaps between the thermostat and its mounting point for more consistent heat transfer.
Identify each thermostat before fitting.
The temperature value is stamped directly on the terminal. Match each thermostat to the correct circuit before reconnecting the wiring.
The parts needed for the replacement.
The set includes one 107°C thermostat, one 145°C thermostat, one spring, and thermal grease.
Check the thread and terminal before ordering.
Confirm the M4 thread, temperature markings, terminal shape, and mounting arrangement against the parts currently fitted to your machine.
Final safety reminderDisconnect the machine from power and allow it to cool fully before inspection or replacement. Electrical and boiler work should be completed by a competent person. HomeBaristaMods is not responsible for damage caused by improper installation.
