Gaggia espresso machines

cross-posted from: https://lemmy.nowsci.com/post/9721947

Hi all,

I've got an uncoated aluminum boiler to replace the flaking one in my Gaggia Classic Pro Evo. Given that aluminum boiler coupled with the brass group head will cause galvanic corrosion, what are my options?

I know I can wait for companies to get chrome plated group heads in stock, but I hear the new (since April) GCP Evos are using the brass group head and the uncoated boiler. How are they pulling that off?

Thanks.

I just picked up a Gaggia Classic 2019 manufactured in March 2023. I was originally wanting to get the new EVO model, but it is not available where I am living right now which is a bummer, but I am not at all disappointed with the 2019 model as it is making very good espresso. I have owned 5 different machines over the decades, some in the many thousands of dollars that needed to be plumbed in, and thus have been spoiled with good espresso. I was not expecting the Gaggia to be so good out of the box with just a few insights like temp surfing and all the other espresso workflow best practices. Like I am actually very surprised how good it is and all of my family and parents in law feel the same way. I knew it was a solid machine, but this is rather unexpected. I feel zero need to modify or upgrade as it would be pointless. Maybe my tastebuds have changed as I have gotten older, but this thing is seriously on par with any no frills high end machine when used right IMO. I can see why it is so well reviewed and recommended. So glad I picked it up as I was considering a more expensive machine again but felt it was too big for my current space.

To get more into espresso i finally got a used gaggia classic and upgraded it with a replacement controller running the open source gaggiuino project.

Fully with loadcell scales, pressure sensor, pid temperature control and a hand soldered all in one pcb.

You can also use standard arduino style modules for most components but the pcb makes it much more compact and reliable.

In this case the modifications are fully reversible in case a future owner wants to revert it back to stock.

Works great and automates a lot of steps to be more consistent. Now i just need to practice the manual parts of making espresso ;)

Note: this is not my project, i just documented the build process on my machine. Maybe it helps someone to get an overview what goes into such a conversion and inspires more users to attempt it.

The community is already pretty big and many also adapted the project for other machines.
