Is it pretty typical for home espresso machine's frothers to drip during brewing of espresso?  I take beautiful care of my machine, and it had the steam valve replaced 2 1/2 years ago.  I am not mechanical.  It doesn't appear that the drippy tube is affecting my shots.  Thanks.

Interesting discussion.  It is fairly typical for Gaggias to drip, not sure if that extends to most or other home espresso machines.  I had a Delonghi proir and it dripped, perhaps Oscar does not.  It is almost the norm for Gaggia and there is a fix, though it will recur fairly quickly from what I have read.  I would not fix it if I did not feel that it affected my shot as it will recur.

http://coffeegeek.com/forums/espresso/machinemods/607264   Is a leakproof steam valve on a Gaggia possible?

The parts diagram shows 2 bolts into the machine #6 one each side of the valve and 49 is the tubing down.  Also the knob needs to come off and you can see those parts.  You may need a gasket 8.  The valve is seen disassembled in the thread above.  

Click Here (www.partsguru.com)

Leaks are made worse with scale, though it is not uncommon to leak new, the seal is not great.  Mine dripped occasionally new from the box and has not changed in over a year.  I almost sent it back but then read threads on Gaggia leaks and decided that most drip.  Too much leak could leave the tank a little below full and possibly then have steam above the water.  Of course Hx machines are designed to have steam above and the closed, pumped, loop is the tubing through the tank.  Probably better explanations, but this diagram may help.  Steam leak on Hx ahould not affect pump pressure and would autofill if water becomes low.  Gaggia and most SBDU do not autofil.

Hope this helps, sorry if you already knew  :)

Thank you, thank you !   I knew that I have heard this time and time again that the Gaggias tend to drip from the frother wand.  I ALSO heard that the fix is easy, but recurs quickly.  Honestly, would I know if it was affecting my shots?  Hmmmm, I hope I could say yes to that.  I KNOW that my cappuccinos that I make at home are normally 100X better than the ones I get in 95% of coffee shops, so I must be doing something right; thus the dripping is probably not affecting my shots.  I really appreciate your response.  Of course it is human nature (maybe?) or the teacher in some of us that maybe think that I've not been diligent in descaling & backflushing.  Not the case.  I treat my machine beautiful.  I'm just not mechanical.

I used my Gaggia Classic for five years and just recently upgraded. Mine is going to my daughter and her hubby. First three years no leaks from wand, year four leaking occurred.
I dont care but it bothered me. I bet you put a glass under yours too. So I replaced the valve. It was very easy. Chanty if I lived close I would do it for nothing for you. Mine doesn't leak now
and it was that way for a year. I bought an extra just in case and will pass it along to my daughter. Bottom line is who wants a leaky espresso machine,especially when its such a great machine.

Gaggia backflushing from PartsGuru seen here.  

Click Here (www.partsguru.com)

I backflush with water daily.  I do not believe that it will harm the Classic and in fact is just using the 3 way and OPV similar to pulling a shot.  While you hit full pressure with a blind basket, the OPV limits pump pressure.  Most of us set to 9 - 10 bar and that is well below pump rating.  Many machines use similar ULKA pump and backflush daily. Once every week or two, I remove the screen and backflush with cleaner and clean the screen, and get a few grinds out and see how discolored the back of the screen was.  I do not backflush with descale as PartsGuru suggested and have not heard much about that.  When I started I did not yet have the blind basket and waited a few months.  It seemed that the 3 way was sluggish and did not backflush as well.  It is hard to make up cleaning if you get behind.  Is there a reason not to backflush frequently may be the question?

The Yahoo Gaggia group used to be open to read, now you have to join I believe.  When I was starting I read there and found about the common steam leaks.  So common that they had the repair by cutting the valve so that it would open for cleanout.  It it very common.  If I got a new valve I would also try to fix the old one as in the prior thread posted.

Iluvdabean,
Man, I'd take ya up on your offer about replacing the valve if you leaved close.  Alas, no one seems to repair machines in Metro Milwaukee, Wisconsin or even Wisconsin for that matter.  I have to almost beg to get my machine fixed when I did need it repaired, and that was different states a couple times..... It seems to be dripping more so (now that I'm "tuning in" on that issue).  Maybe it needs just a washer?   I know, about actually 1 1/2 years - 2 years ago, when the whole steam valve assembly was replaced cuz water was literally streaming (not dripping) out of the wand--it stopped dripping completely for a little bit.   This is just so frustrating to me because if it was a simpleton fix (AGAIN, NOT mechanically minded), I would attempt it.  I'm afraid of wrecking this machine.   I once had someone repair it & when another person repaired it a year later told me somehow the wiring was goofed up.  If someone "mechanical" can do that, makes me even more timid to fuss around with it.   You would think that with all the coffee "snobs" in Wisconsin, there would be someone out here that actually works or wants to work on a simple(?) repair......... :(

Thanks.  I saved the wholelattelove 14 step directions on removing/replacing steam valve assembly.   Arghhhhhh.   Uhmmm, probably won't be doing this.
