Depending on where it's leaking...you have five possible connections.

In all cases, you must support the valve assembly with one wrench while 
tightening something else with another wrench.  Otherwise you will twist the 
valve assembly and ruin your water line.

Also, do this with the machine COLD, unless you like steam burns!

1--The valve assembly attaches inside the machine to the water line.  If memory 
serves, this is a flare fitting, meaning it has no gasket and seals via 
compression.  The line is copper (soft) and so it shouldn't take much.

2--The chrome nut/thread that the water line attaches to is screwed to the 
valve housing, also with a flare fitting.  This is not normally removed for 
service, etc. and I'd be surprised if it's leaking.  If you can't get this one 
to seal, you could add teflon tape to the threads.

3--The valve stem itself (i.e. the part that the black star knob is attached 
to) has two o-rings on its shaft, as well as a white nylon seat at its end.  
The white nylon seal commonly fails due to overtightening.  You can carefully 
pry the white nylon seal out and turn it over to extend its life.  The o-rings 
don't fail often in my experience, but they should be easily found at the local 
hardware store and/or online at Chris Coffee, WLL, Espresso Parts, etc.  If 
possible, put a little food-grade silicon grease on the o-rings before 
reassembly.

4--the chrome threaded cap that goes over/around the valve stem does not seal 
anything--it just acts to complete the assembly and to keep the valve stem from 
being able to screw out all the way (giving the user a straight jet of steam in 
the face).

5--The wand itself has a white nylon gasket between the big nut that holds the 
wand in place, and the valve assembly.  Again, a pretty rare failure, but it 
has happened to me once in 6 years or so.

For me, the most likely culprits would be #3 above.  A failed nylon seal shows 
up as water dribbling out of the end of the wand all the time.  Failed o-rings 
show up as water dribbling out from behind the star knob.  Also check #5, it is 
another easy check/fix that doesn't require the assembly to be removed from the 
machine.  In both cases, look for cracks/chips/etc. on the seals and replace as 
needed.  One charming thing about the white nylon seal--I have never been able 
to find it by itself; I've had to order the valve stem and/or the whole valve 
assembly instead.  So I have an extra assembly or two.  If you need the white 
nylon wand seal, let me know, I have extra and can send you one.

Anyone know what type of plastic the wand/valve seal is?  We should set up a 
collective to make the seals for the $0.10 they actually cost, instead of 
buying extra parts we don't need.

best,
bmc

p.s. I can send you a picture of all this if it would help.
