My steam wand is loose and it leaks (when valve is open only) where the steam wand connects to the front plate of the machine.  I took it off and can not find a part that appears to be damaged.  The steam wand wiggles easily (the water tap does not).  I tried switching the spring and viton gasket from the water tap with the steam wand ones, the steam side still leaks and the water side does not.  Anyone have a thought on what to do next?  I have descaled recently...

The knobs that you turn are connected to the ends of the valve shafts. You say it leaks when the steam valve is open, do you mean that steam is coming up the shaft and out behind the knob?
Or, on newer machines, the whole valve is forward of the front wall of the machine and the wand is a ball and socket type joint, swinging in all directions as well as pivotting.  In these, the wand will often loosen from the ball-joint and leak at that thread.

If it's the old ECM Giotto where it only swings left and right, parallel to the face of the machine, you'd need to replace the brown o-ring hidden in the nut that holds the wand to the front of the machine.

If it's just a loose ball and socket, hold the little 6 or 8 mm flats on the top "Ball" part of the wand and turn the wand clockwise from below to tighten it.

If I don't make sense, can you take a photo and draw an arrow where the steam comes out?   I am only familiar with two eras of Giotto.

It is the older style of giotto.  The steam does not come out behind the knob but rather at the "base" of where the wand attaches to the front plate.  I'm assuming I need to replace the brown o-ring you mentioned, but I haven't found it yet =D

Yes. Hold the bulkhead fitting so that it doesn't turn in the front wall of the machine, and you can unscrew that chromed nut that the steamwand pivots in.  You'll see the o-ring as soon as you have it open. If your wand no longer stays where you point it, and sags due to gravity, replace the teflon gasket that provides a bit of friction on it, as well.  You'll see what I mean when you open it.
Used appropriate sized wrenches or good adjustables. Don't use pliers or you'll make the chrome ugly. The brass underneath is softer than the chrome.

Thank you very much!  Do you by any chance have links to where I can buy those replacement parts?

Alright - I've given it a good shot and for the life of me cannot find this o-ring online.  I think I found the part number for it (?c449900786), but does anyone know where it or a suitable alternative can be bought?
