Subject: E61 Brew Group and Thermal Siphon Question
 

I was under the impression that the water to maintain the temperature of the E61 Brew Group came from the Boiler in my HX machine but after looking at it's internals I'm not so sure.  Does the water actually come from the Heat Exchanger instead?  If so, then does the 3-way solenoid play a part in this?  When looking at my machine there are two copper pipes that go to the Group Head.

Any insight into this is appriciated.

Yes.  No.

The thread "E61 Purchase Time" is one of many that includes a discussion of the E61 design.  The ECM conceptual rendition of it is easy to understand, although a little vague in details.  Below are some other threads that touch on different aspects:

Although not specifically for your machine, this La Valentina parts list includes the best schematics I've found on the net.  Below is an image that I borrowed from it to show the difference between the semi-automatic with 3-way solenoid (left) versus the lever-activated model (right).

Now that is what I call a parts diagram.  Thanks for the information.
