@"DavecUK"#p12737 Thanks Dave.. interesting because it occurrs to me the Vesuvius plus a bluetooth connection and the right programming would be the perfect synthesis of build quality (ECM) innovation (Decent) all wrapped in a traditional E61 style body. Can you convince @"Paolo_Cortese"#90 to update it? I love mine, which I bought second hand largely on the basis of your reviews; its taken me a year but I think I've finally got the hang of it!

@"Grahamsphillips"#p13074 I'd put an order in for one of those!

> @"Grahamsphillips"#p13074 Can you convince [@Paolo_Cortese](https://coffeetime.freeflarum.com/u/Paolo_Cortese) to update it? It would mean losing that lovely old, but proven super reliable main board…..

hi, could some one with a vesuvius with the wood/metal handle please email off my sig

I have a wooden handled bottomless pf (generic) that I bought for my Elizabeth then a barista pro IMS basket in it. Will this IMS basket fit the supplied bottomless pf that comes with the Vesuvius?

So, my Vesuvius arrived today. I didn’t want to start another thread and this looked like the most appropriate place to discuss my first day! It left Italy last Friday and arrived in my house today - 6 days, yipee! Mine was definitely used, the plastic was gone from it, there was dirt here and there, spilled water underneath the water tank and for some reason the pipes going onto the tank had a black residue of some sort on parts of them. The panel on top of the machine, where the cup test sits is pretty badly finished with dirty plastic covering it but doesn’t bother me. I didn’t pay for a brand new machine I guess!! Assembling was easy as the provided guide is comprehensive (remember the first thing you do is unscrew the four screws on the top of the side panels, no hammer or anything required) The Teflon furniture gliders I pre purchased are perfect for moving it around on the counter top. A bag of felt pads come with the machine. I put 1L through the group 200ml at a time with at least 15 seconds in between. I then emptied the service boiler twice as per manual. I noticed the shower screen had coffee on it so I soaked that in puly caff and gave a good wash. At this stage I only had time to pull 4 shots as I had to leave! I was close to dialled in by the fourth albeit a bit long but I took it with me in the car- I have to say it was very very nice. So I look forward to playing with it tomorrow. I thought I had a dodgy touch screen as it didn’t seem to respond some times but apparently there are different delay times for different choices on it.. phew..! Looks a stunning machine on the counter and I love the almost totally silent pump. I thought the water reservoir wasn’t the best design but I think I’ll get used to it and won’t have to be refilling it so often when I’m not flushing the system through and just using it to make coffee! It really is a different operation to the Elizabeth but I don’t think it will take long to get used to it. So, I can’t wait to drink coffee from it tomorrow

[upl-image-preview url=//i.imgur.com/cumOEwk.jpeg] I use this type of oil can to fill any of my machines with water.

@"DavecUK"#p13617 I ordered this one by someone’s recommendation on here: https://www.toolstation.com/laser-plastic-measuring-jug/p20428 Seems really ok although the spout is not very flexible

@"prezes"#p13619 mines very similar and probably on something from nu-man, the image I found seems to have brewers droop.

I used a plastic 2 litre water bottle today!

Vesuvius Pressure Profiling Machine - General Discussion

DavecUK

The valve splits halfway down for lubrication, nothing in there should need replacement for a long time (many years).

Adrianmsmith

DavecUK

Thanks Dave

Just feels like valve plug is sticking slightly and needs a clean

Has there been a step by step or any info to remove the valve from the body to cure the slight leak.

May become clear once I get time to have a look

John_Yossarian

Adrianmsmith I suspect that you might find some generic type steam valves blown up diagrams on the net. I do not know which one exactly ACS use but surely they have not developed it from scratch. As @DavecUK said, these are bullet proof and hopefully you should be able to resolve it.
EDIT: I hope it is not against the rules but here you can find a bunch of coffee machine manufacturers with steam valve diagrams: https://espresso-solutions.co.uk/

DavecUK

Hope this helps, this is the disassembled wand., I have the main body rotated 180 degrees the wrong way.

Plus a short video.

Adrianmsmith

DavecUK

thanks for this Dave.

very interesting. I guess my “leak”, tiny as it is must be from the copper connection to the back of the valve, inside the machine, as its seen on the body. the coating is blistering slightly. i dont know the history or if it has previously been disassembled. will update with my findings. when i refit, i would like to find a copper or stainless washer to hide the blistered body coating…… but then i have to do the water valve, just to make it match!!

hope i will have time at the weekend to investigate. will be interested to know how easy it is to access the back of the valve from inside the machine. 🤞🏻

DavecUK

Adrianmsmith I think your machine used to be stainless?

Getting to the rear is a mild pain in the ass, made easier by boiler removal..

Adrianmsmith

Tap required to clean out these threads. what size?

DavecUK

finally today i have time to look at the V

as you said, pain in the A to get access but my steam valve is behind the electrics no the boilers so 1% easier!!!

As suspected no thread locker on the valve on the rear side. BUT it did have from the factory, Previous owner “hasn’t worked on it” Well, someone clearly has! threads totally dry and easily removed by hand.

Dave do you know the correct tap size please to clean out the old thread locker on the back side of the valve.

Also what semi permanent thread locker would you use to re-assemble?

Adrianmsmith

Thanks Dave.

That would explain things

It’s an Evo day today until it’s sorted.

Adrianmsmith

The plot thickens!!

looked closely at the evo and vesuvius valves and then your picture to realise the teflon(?) washer is missing.

then realised the valve could by hand be unscrewed from the back boss!

no washer. lo threadlock….

havent removed it as steam wand was still on :) do you happen to know the size to order?

DavecUK

Adrianmsmith no washer. lo threadlock….

havent removed it as steam wand was still on :) do you happen to know the size to order?

I wouldn’t worry about the washer…you can simply use PTFE tape on the threads…the washer isn’t doing very much. Use enough that it’s very tight to screw up so it won’t leak and when refitting secure from turning when tightening up the knot on the back of the panel by holding the front nut. It also means that future internal maintenance will not require valve removal from the machine.

It’s very strange no threadlock or washer though?

kautivo

kautivo Dear @DavecUK , remember if you have time for your visit in italy to see my vesuvius in Acs factory…we haven’t news i understand for host milano they are busy but it would be interesting if you also can help with the diagnostic…

Thanks a lot!

DavecUK

kautivo I will spend a few hours with Paulo tomorrow morning. Looking at your machine but then I have to return to the UK.

kautivo

DavecUK Ok keep us informed please, i hope a final solution!

If the problem can’t be repaired i accept one Falcon I pleased!!! Hehe @Paolo_Cortese

DavecUK

kautivo If the problem can’t be repaired i accept one Falcon I pleased!!! Hehe

It’s a very strange problem, it doesn’t really make any sense? I have 4 tests I want to try.

The Falcon I is still a prototype, software and PID settings still to be finalised plus start/stop shot button to be placed on the front panel. I am hoping to get it to the UK so I can test and work on the software. 🤞

kautivo

DavecUK Ok let us know when you see the machine!

Thanks a lot!!!

kautivo

Ok let us know when you see the machine!

DavecUK

kautivo I have worked on the machine this morning and

Cannot get any difference with steam boiler on or off HX enabled disabled. As this didn’t make any sense I was not surprised.
The pump PID settings required a lot of work. This is because the Cruzet drive unit on the pump had changes in later machines than mine.
The settings will always be a compromise based on the type of profiles used/phases and times. e.g the system gives a straight 9 bar shot a very different proportional and derivative pump response, compared to a shot with preinfusion at 2 barn then a rise to 9 bar as you are closer to the target pressure for each phase.

The above would result in a slight overshoot for a straight 0 to 9 bar shot because of a big proportional rresponse. By the time the derivative kicks in you get a slight overshoot that takes a long time to settle

Or conversely A profile shot with a 2 and a 9 bar phase would actually be slowed down as it gets to 2 bar. And then the rise to 9 bar is a shorter distance, so the proportional response would be smaller and the derivative response would have more effect. So you might not quite reach the 9 bar you set.

In the above 2 examples you might use more derivative for the first and more proportional for the second. It all really depends on the profiles. Or leave the average settings I programmed and simply adjust the pressure profiles as needed, to hit the numbers you want.

kautivo

DavecUK But then why when you switch off steam boiler the profile 8sec 2bar and 40sec 8bar works right and if you switch on the steam boiler it jumps over 8bar?

kautivo

DavecUK Honestly i think the problem in this case isn’t configuration software!

kautivo

But then why when you switch off steam boiler the profile 8sec 2bar and 40sec 8bar works right and if you switch on the steam boiler it jumps over 8bar?

DavecUK

kautivo we couldn’t simulate any abnormal behaviour. I am at the moment uploading videos with different settings but they still show nothing significant. The ideal mis settings I gave earlier were done with coffee. i spent hours on the machine this morning and I have to leave and catch my flight now.
