Silvia Classic
The Silvia Classic is a single boiler espresso machine, which means you will have to switch between the two boiler modes when steaming milk and brewing espresso. Because of this, you will have to make sure that you have the steam setting OFF when pulling shots of espresso.
To pull a shot of espresso on the Silvia Classic, you will turn on the machine. When the light turns green, your machine is at temperature and ready to brew. The coffee button will start and stop your espresso.
Silvia Pro X
The Silvia Pro X includes upgraded features like a digital display, shot timer, brewing temperature control, Variable Soft Infusion, and - perhaps most importantly for the sake of this blog post - a double boiler to steam milk and brew espresso at the same time.
To pull a shot on the Silvia Pro X, you will turn on the machine. Once the digital display features your desired brewing temperature, hit the brew button to start and stop your espresso.
