i don't know where to post this. i am trying to fix my la pavoni by myself. the wiring is fine, everything is fine... its just that when I pull the lever up, i do not pull any water. i haven't changed the way i fill or tamp my coffee. i believe i may have caused this problem by packing too tight and forcing the lever down. i've been doing this repeatedly over a few years. This is not an issue of just packing and tamping looser. I believe that i've blown the gaskets in the pulling body. i have learned by my mistake and learn how to properly fill and tamp. is there hope for me?
please redirect/let me know where to post this note.

Welcome to coffeeGeek! Actually this should have been posted under "Lever Machines" possibly a mod will be kind enough to move it for you. Sounds like you've blown a seal. The La Pavonis are actually fairly simple to work on. You can get info, as well as order parts, from at least a couple of well known sources-

If you get steam out when the steam valve is open, then the boiler is pressurized. With the handle fully raised, the piston should be at its uppermost position, above the port from the boiler. If the boiler is pressurized, the lever is fully raised and no water is flowing out of the grouphead then the piston isn't clearing the port. If it's hot but not building pressure, there could be a serious leak, you'd probably see the steam.
If the lever is quite loose and moves up and down significantly without actually moving the valve-stem, then either the holes in the lever-arem are worn, the pins through the arm are worn or both. If the valve stem moves securely with the lever, then it is likely that the piston is unscrewing down the bottom end of the stem. You can disassemble the head, secure the piston (And check/replace the seals while in there).
