One more question - the steam wand is leaking a little steam from the top of the tip, where it attaches to the wand arm. What should I use to remove or tighten it?
The tip is textured, but I can't undo it by hand and it doesn't have bevels for a wrench. I'm thinking of a pipe wrench with a cloth between it and the steam wand tip - is this a good idea?

I just noticed that steam leaks out of the water exit chute from the 3-way solenoid when the machine is on, warmed up, and idle. Is this normal? I backflushed a few weeks ago, but didn't noticed if it was doing this before.

Thought you Rancilio S series fans may find this interesting so I decided to post here :)

Scale was so bad, I scooped it out of the boiler, wire brushes did nothing..... original owner was an idiot

Why did you use muriatic acid? I have a hard time thinking of another acid I'd want to use less. That stuff stinks to high heaven - like vomit if I remember correctly. I guess you'd definitely know when it's all out?
I should be receiving an S24 tomorrow that will need to be descaled. I'd like to use citric acid, but my local homebrew store didn't have it. They did have "star san," a phosphoric acid solution. Yes, it's the same stuff as in coca cola, but a LOT more concentrated. I decided to skip it and start with a bunch of lemon juice and salt and see what happens. Next on the list is vinegar unless I hear some other suggestions from here. After that it's glacial acetic acid, then hydrofluoric for the last bits. Just kidding on those last two.
Here are a couple threads I've been reading to figure this out:

I think all the problems are now solved; just one more question...
After completely disassembling and re-building the steam and hot water valves with the existing parts (new ones haven't arrived yet) I found that I simply wasn't opening up the valves far enough! :) I'm used to a Silvia and Gaggia Espresso, where the steam flows right after the knob bottoms out. These valves open up midway through their range of travel, and are a very different experience. And they don't leek at all!
The back panel came off after unscrewing 2 semi-hidden screws near the water reservoir.
And somehow the pump ran dry in this process. My god do they sound awful when dry! I thought I'd fried it, but I filled the tube with water and blew into it when I turned it on, and it re-filled with water and works fine! So now the machine is fully functional- I'm so excited!
Before I replace all the exterior panels, I'd like to insulate the boiler. Anyone know where I can get the boiler insulation that ships on the Epoca series (S-1, ST-1, or E-1), or something comparable?

Dear All
I have opened the boiler of my S20 3 Group coffee machine. It dad a lot of scale in it that I cleaned out and then soaked it in a citric solution to clean it out. It is now clean inside but there is a few spots inside where the chrome has come off and the copper is exposed. Do I need to have it re-chrome, and if so does it need to be bright chrome or hard chrome?
Jacbri -- Thanks for the pics and diagrams! What a great resource.
I hooked up a pressure gauge to my S24 today, and I'm putting out 170 psi =~ 12 bar. Can I use a Silvia adjustable OPV in this machine? The connections look right; just hoping for some confirmation.
