The milk-steaming unit on my La Pavoni PC-16 is starting to leak at the joint where the fitting meets the boiler. I suspect all that's needed is a new o-ring and a tightened nut: the problem is that the nut that needs tightening is actually INSIDE the boiler, and I can't reach it with a wrench. Anybody know how to get at it? Is there a special tool? Does the boiler itself come apart somehow?

Re: Steam fitting leaks
Yes you require a special spanner which has a slight bend at the top. You can get them at most hardware or mechanic style stores as it is a type of tool mechanics would use. I believe it to be either a 16mm or 19mm. Once you have a tool that fits, hold onto nut inside boiler and unscrew the steam assembly in an anti-clockwise fashion and remove. there will be a brass washer and nut which will probably fall into the boiler. Remove these from boiler and if you go to www.theespressoshop.co.uk and click on the la pavoni machine on the right it will take you to a full parts list where you can purchase a new washer and nut. Then just re-attatch in opposite fashion.
I hope this helps.

I HAD the same problem. I fixed it for 50 cents. It takes the removal of 4 screws (2 phillips on top, 2 long standard on bottom by the group) to remove the top to access the steam wand valve. Once the the top (and the chrome bezel) is removed, then screw out the valve counterclockwise buy ALL THE WAY until it comes out. There are 2 O-rings on the stem of the valve that wear out, Cut these off with a sharp knife, go to your local hardware store, buy 2 new ones for 50 cents, install new O-rings, and reverse the disassembly procedure. Voila, no more leaky steam valve!
It seems to me that your pressure stat which is inside the base of your machine needs replacing. I would try to give it a good descale and if this doesn't do the trick then a new pressure stat is what you need. Prob around £20 if you buy it and do it yourself. www.theespressoshop.co.uk and just click on the little la pavoni machine for full parts list.
Try opening the steam nozzle while trying to pump the water through as this will get rid of any air locks. Otherwise it may be a build up of scale in the boiler or the pump itself. Try that and descale if you can.
You can buy a service kit for your machine at www.theespressoshop.co.uk and that contains all replacable gaskets and washers and gives you an exploded diagram and sachet of grease and descaler to get your machine back in as new working order. The service kit you require is the "old group service kit" and is about £20. If you go to the website above and click on the la pavoni machine on the right hand side of the home page it will give you the full parts list.
The black steam knob is bonded to the shaft. The shaft/knob assembly is removed by rotating the spring keeper on the brass housing the shaft fits into by 90 degrees to allow the shaft to be pulled out once the knob is rotated enough to disengage its thread from the brass housing.
Once the cover over the boiler is removed you will see three thermostats mounted on top of the boiler.
The middle one has the reset button located between the two power connectors. Push it down and you will hear a metallic snap as it resets.
I now have a working La Pavoni Pisa Espresso Machine again and it was free to fix it!
i havent heard of this issue , it could posibly be the bent steam wand , but the nozle is made to be that way, because the pavoni eurpicola doesnt produce enough steam pressure , it enables you to create better froth
