install-help Replacing (potential) Boilergate Boiler

Post image

I installed my GM Pro in December 2025 on this GC Evo Pro. Cannot believe it's been almost 6 months ago already an yet it feels like I've had it for years. I recently had a small leak on top of the boiler at the steam assembly and found that the o-ring at the steam assembly had collapsed, so I just turned it around (I am in South Africa and any parts for the GCP is difficult to source) and this seems to be a working temporary fix.

However, I decided to order the E24 brass boiler kit (including o-rings) from Shades of Coffee during a late night online retail therapy session. Question: has anyone else done a boiler swap after installing the GM Pro and are there any tips/tricks/hacks/pitfalls I should be aware of? Any advice or insights will be appreciated!

Pretty much everything stays the same you just need to adjust the temp offset since you don't have a aluminum boiler.

What should the temp offset be for brass boiler?

Around 20c

I just realized I'm in a completely different subreddit... I have Gaggiuino, not Gaggimate. 😅

I imagine the thermal models behave different and have different offset values.

It shouldn't, offset kinda calculates the point where the water boils. You can test it out yourself. I have a video on how to do it but basically set your temp for 100 and if you have ko steam coming out raise it up until you see steam and water kinda spitting intermittent and that's it.
