Part 28 here, on the Gaggia

Click Here (www.partsguru.com)

In your asking is the answer that you did not adjust it :)  It is simple to adjust you have to assemble a gauge to fit on the PF with the spouts off.  I will find a Youtube if you are interested.

This will help if you are interested, a recent thread on Gaggia Classic Pressure

http://coffeegeek.com/forums/espresso/machines/572173

Youtubes in the thread.

I will let you get back to the grinder, sorry to interrupt.

Thanks.  About 1 1/2 years ago, I had an expert on Gaggias completely examine, check pressure, etc..  I don't know how often that has to be done.  I will look at the link you sent & thanks.

You might check with him.  "Checking pressure" could simply be checking to see that is still at factory setting, or it could be setting it to 9 bar.  I think that most set it to about 9 and do not check it again unless some pressure problem arises.

I'm thinking that isn't it because I just dismantled the burrs a couple months ago and cleaned thoroughly.  I only go through 4 shots of espresso a day--so not using a ton of beans.  Plus I also use Grindz.  I'm next going to try something a little different with my dosage.

Posted September 2, 2013 link

I would take it apart again.  I have not used Grindz so I can't comment on if it helps, but I have seen the issue fixed a few times by taking it apart and manually cleaning out all of the ground coffee.  I can't explain why this has an effect, but in my experience it does.

I know people say the humidity in the home wreaks havoc on beans & can cause the gushers where you have to really make it fine to get a normal result.

Posted August 31, 2013 link

I'm from Denmark up to 85% relative humidity at night :/,,,

I experience the same problem if I let some coffee overnight in the hopper! Try keeping the beans in the bag, if that solves your problem, the the humidity is to blame, for sure!!

personal opinion -> Besides beans loose aprox 20% of flavor on daily basis if let exposed to the air like in the hopper. Complex flavors (chocolate/caramel/nutty/fruity/etc.) are the first to go, then the punch (caffeine) and the basic flavors (bitter/spicy/sweet/sourly*/etc.) starts to fade away.

Not all peps feels this way, however you can test your self -->> let some beans get exposed to air for couple of days, while you keep the rest on the bag -> pull a shot of each -> then compare. Most would agree that there is a difference, although far from all agrees that it's worth the faff..

*NOT sour but sourly, BIG DIFFERENCE!!

Good luck :)

I'd also suggest getting a tamper that meets the diameter or your basket really nice. VST for example is 58.3mm. After switching from 58 to 58.3 i've noticed a huge difference in the amount of gushers. Something about the water not gushing along the sides of the basket.

I'd also examine how you're recalibrating the burrs. maybe try to go just a smidge more finer at your starting point.

I have a 12oz. glass container with an airtight metal cover.  I keep the 12 oz. of my pound in that & the rest of the pound (4 oz.) in the bag it came in.  It doesn't but the blink of an eye (or so it seems) to go through the 4 oz. in the bag.  I never leave anything in the hopper.  I heard beans can start to go stale in 5 minutes.

It seems that it may be the dosing.  I hope so cuz that would really cut down the variables in my issue.  There seem to be so many variables in getting that great shot.   I have a Gaggia Classic espresso machine so as you already know it uses the 58 tamper.  Where did you find your 58.3 tamper?  Expensive?  Tight fit?  Thanks!

Can I ask what type of scale you use to weigh your dosages?   I only make 2- double shots per day so hopefully there is a very small, not so expensive scale out there?  Thanks.
