I have this model of Gaggia. Bought new in 2017.
Replaced the steam arm with the Rancilio Silvia arm and have had no problems at all.
So far excellent machine.

The screw-in part of Steam Temperature Thermostat that sits on top of the boiler has snapped off and stuck in the machine.
How can I get it out?
