How to adjust the LaPavoni / Gaggia pressurestat

[prof_stack]

Can any wise soul here direct or guide me on how to get to the pressurestat on a Gaggia Factory / LaPavoni Prof?

Does the screw in the drip tray have to come out first? If so, what kind of bit is needed? Sure doesn't look like any torx bit I have. Is it a "star" type screw? Weird.

Or does the black base just pull out and down from the front lip?

I want to adjust the stat in my older Gaggia before putting it up for sale now that the new Factory is working as advertised. I've been told that the stat itself can be tricky to adjust and breakage is common among clutzes like me.

You can buy the bit that turns this or if you are crafty a good pair of small needle nose pliers will turn it (maybe).
The pressure stat has a blob of glue on it that you need to remove before you try to adjust it.

Thanks, the needlenose pliers did the trick and the bottom came off nicely. Here is what I found:


The plastic turned with some resistance, being warned not to force it, I was.

I screwed it away from the brass part and tested the unit. The gauge now goes up almost to 1.0 and then falls back a little before doing it again in a short time. So it appears that I got it fixed up by myself without messing up!

That was easy.
