Rancilio Silvia Pro/Pro X: Resetting the Coffee Boiler Safety Switches

Is the coffee boiler on your Silvia Pro/Pro X failing to heat? A tripped safety switch aka high-limit switch could be the culprit. Below are instructions for resetting the safety switches.

Tools Needed:
  • Phillips Screwdriver

Note: The machine should be unplugged and cooled to the touch before beginning.

  1. Remove the top panel from your Silvia Pro or Pro X.
  2. Locate the safety switches on top of the coffee boiler. 


3. Firmly press down on each of the red buttons with your finger or a screwdriver. If the switch is tripped you should feel the switch push down and hear an audible click.



4. Plug in your machine and test to see if the boiler begins to heat.
