I went about my business to let her warm up (foreplay as it might be considered
). When I returned, I noticed a huge puddle of water under her posterior. 
NOT GOOD!
So I started the process of undressing her. About 30 minutes later I finally had all of the casing parts off. Now that I've done it, it should be easier the next time (God forbid).
There is a pressure release valve (forgive my ignorance if this is not what it is), which sits in a little copper cup, atop the boiler. As she warmed up, water was coming out of this valve into the cup. Then the cup would overflow.
I figured that the 19mm bolt in the center of the cup was in need of tightening. In order to get to that bolt I had to partially remove the boiler. (There is a cross member bar that prevents easy access).
I tightened down the bolt, dried out the water, and fired her up again. NO LUCK! Still overflowing.
I called Chris.
The tech was gone for the day but a very knowledgeable guy was available to rescue me.
After several diagnostic checks we ended up removing the automatic boiler fill device. Low and behold, when I took it apart, a tiny little shard of brass fell out of it. Viola! I found the culprit!
All in all, I spent 3.5 hours getting her back to tip-top shape. I took some photos of the process for you guys.
BTW~ I haven't seen the back of the machine since I bought it (up against the wall). What a shame! The back is so pretty!
