Rancilio Silvia Pro/Pro X: Draining the Steam Boiler (No Power or Heat)

This article shows how to drain the steam boiler of a Silvia Pro or Pro X when the machine is unable to turn on or heat.

Tools Needed:

  • Phillips screwdriver (long-reach if available)
  • Pitcher or similar vessel to catch water

Note: Depending on when the machine was manufactured a 7mm deep socket, ratchet extension, and ratchet may be needed.


Be sure your machine is unplugged, completely cooled, and depressurized before beginning.

1. Remove the panels of your Silvia Pro or Pro X.

2. Drain the steam boiler by disconnecting the push-connect fitting from the pump by pushing the collar in and then pulling the tube out.  Place the Teflon tube into a pitcher.  Open the steam valve to allow water to flow through the Teflon tube.
