If this thread is still alive, I’m after advice about the grouphead gauge. It sits idle at 2bar, there’s a screw at the rear, and presume that’s to adjust. Just unsure how to take the gauge off. Anyone have experience of doing so?
Not an issue, would just like it sat back to zero.
Also read about firmware and have machine 003 from David, so it a V1 model. Do I need to update it, if so how? 🙏
The whole gauge just unscrews, square nut at the back. need a very thin gauge spanner 😎 .
The screw at the back is to remove the bezel .
This type of pressure gauge has a finite life and is very cheap to replace. They are prone to become strained over time.
Mine was number 5 so sat on the same bench for assembly originally!!
I believe the firmware should be good and not require updating…….

Adrianmsmith perfect Adrian thanks pal.
Will order a new one and maybe order the flush lever while I’m at it. 🙏👌
You will get a collection eventually!!
You can take off the pointer and set it to zero BUT you have no way to check calibration, except, with the evo if it starts at approx 11 bars its probable still good enough!!!
Take the gauge off . Pull off the outer bezel remove the back screw…. Its in pieces!!

Hate to be that guy but anybody heard from ACS in the past 3ish weeks? I have an email and subsequent follow up asking for the replacement parts for my steam wand valve (among a couple other things) but haven’t heard a peep.

Inspirado I have an email and subsequent follow up asking for the replacement parts for my steam wand valve (among a couple other things) but haven’t heard a peep.
Who did you contact?
I have communicated with this email address in the past so assumed it was still good (also received no auto reply saying it had been changed) z

Paolo has been helping me with a problem from Sunday to Tuesday this week. But has gone quiet since.
A few thoughts for evo2 and vostok owners who have the solenoid valve to dump the remaining water at the desired shot end .
The burning question “ how often should i back flush”.
The simple answer. Its not really necessary!!
4th december 2024 i had a look at the back of the shower screen and inside the cylinder.
30th march 2025, this is what i found.
Gave it a quick clean anyway
This is a minimum 3 shots per day so approx 350 shots minimum without doing anything but pull shots.
The bottom piston seal was in need of a smear of molykote.
Lever Action was smooth this morning. its silky smooth now again!!

I have a little leak from where the 90-degree fitting comes out of the boiler and goes into the copper pipe, once I take it out what would be the proper sealant to use. Thanks in advance for your help. 
Ptfe tape is about the best.
Ive never had anything remotely similar though so could he wrong 🤪
You need a medium weight tape.
Do not be tempted to over tighten the fitting.
If its tight and just past the 90 degree spot you need start again with more tape. Count how many wraps so you get it right the second time.
Will say this again as it is important. DO NOT be tempted to over tighten it or you will regret it!!
Simple fix. Big mistake if you get it wrong 😎😂
Will answer your next question tomorrow about how to remove it. Its easy btw . BUT Do NOT try to do anything with the back of the valve the pipe goes to .

Adrianmsmith Thanks for that, I pretty much thought it would be thread tape, but pays to do it properly the first time.
Maybe not so obvious but prior to working on it, after making a coffee(!) turn the power off and draw quite a bit of water from the boiler through the water valve.
Having studied it i thought it looked like a lot of work to remove the pipework in to the elbow . And as i said above, my opinion, do not think of removing the pipework from the back of the valve .
My solution . Drain as above . Turn machine on its side and LOOSEN the 3 nuts (dont remove them) just enough to give enough slight movement to get the pipe out of the elbow
I tightened the 3 nuts and replaced the bottom around 3 weeks later 🤪

Also use an appropriate sized spanner on the FLATS of the elbow -don’t grip near the thread.

Adrianmsmith I’m not sure if we are on the same page, the fitting that is slightly leaking is the one on top of the boiler, with the copper pipe coming out of it.
Grunta same page, same book. 🤔🤗
Sleep on it. 😁
I will read tour alternative solution with interest and possibly egg on my face……
And dont forget to remove the nut on the adjacent elbow as per picture.
P.s. copper isnt as flexible as polyethylene.

All sorted, I know what you were saying, thanks for the help
Ok, so it was just the olive not sealing and required ⅓ turn on the nut to seal it?
I guess theres 2 sides to evert elbow 😂😂😂 sorry!!!

Adrianmsmith No, it was the threaded piece that went into the top of the boiler, with the copper pipe coming out the other end.
