Some people are looking for a mod that allows to use low water light on the Rancilio Rialto and Audrey espresso machine for a heating indicator. I think I found a diagram on the web that explains how to do that. I did not open my Audrey yet to see if the diagram is accurate. I am just posting here so that other people looking for this diagram would have easier time finding it than I had. Here is the link to the file in its original location. I also attached the file to this post in case that this source would go away as many others did. Here it is - Rancilio Rialto/Audrey wiring diagram in PDF format and a .gif picture.
I also found a Partsguru.com page with pdf scans of Audrey user manuals and assembly diagrams
Hold on!
I found a forum topic where this diagram was posted. It appears that there is a mistake in this diagram. I will open my Audrey and check if it is correct.
