Based on some of the information available in the Internet, the 3-Way valve would seem to be one of the more misunderstood components of an espresso machine. I have put this series of "slides" together to assist you in understanding how the a 3-Way valve works, its function in an espresso machine, and the basic maintenance that should be followed in order to properly maintain it.

All information presented here is for entertainment purposes only. This information and the diagrams are not intended to give you an education on electricity, espresso machine maintenance, nor on on to make safe modifications to any espresso machine. Always read all precautions and instructions for your machine before proceeding with any cleaning chores or procedures.
