@"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

prezes

Can anyone with this machine tell me what their is like as I think I’m loosing it.

I am under impression the steam boiler pressure drops lower and recovers much slower during steaming than it used to. I had it set at 125c and recently found I had to increase to 127c which is still not whatnot should be.

I flush and wait for it to come back to 127c before starting to steam. Only 160ml milk in the pitcher.
It falls to 122c before you notice it starting to recover although you can hear the boiler kick in around 125c.

I hope it’s just my mind playing games but I am convinced it wasn’t like that.

DavecUK

prezes Check your advanced settings because it sounds as if the steamboiler is behaving more like a PID control than on/off control. You need to set the PID parameters for the steamboiler to behave like an/off controller.

prezes

DavecUK thanks @DavecUK . These are the settings at the moment:

DavecUK

prezes if that’s settings for the steam boiler, change them to kP =20, kI=0 and kD= 0

is there an associated B setting for the steam boiler?

prezes

DavecUK I’m sorry Dave I had to double check. The above are brew boiler settings.

Steam boiler:

DavecUK

prezes make the same changes I suggested. With those setting it’s acting like a PID, which you don’t want and possibly dropping the power by up to 20%

prezes

DavecUK thanks a lot. I will test tomorrow and report back

prezes

So it definitely acts differently. I’ve got it set at 126c yet it goes up to 128c and then slowly comes back to 126c. When steaming it still falls but now not lower than 123c

DavecUK

prezes Which is exactly what you want

prezes

DavecUK yes, it seems to behave mich better now. Thanks for your help Dave.

sketchy

Looking as this issue that Prezes was experiencing, it seemed a bit familiar, as I’ve noticed my steam pressure and temp not being able to sustain itself in a way that I remember. My steam boiler PID settings were exactly what his was (as they are the default from the factory according to the manual). I made the changes that Dave suggested and it definitely helped retain the temp and pressure throughout the steaming of milk. Thanks Dave!!!

Given that it helped, it does make me curious why the default settings were letting the PID control it via its algorithm vs just a binary on/off.

prezes

sketchy I second that as was meant to ask the same thing. What makes me wonder as well is why does this develop with time and is not an issues that is there on new machine with the original settings.

Adrianmsmith

sketchy

That’s good to know

If by any chance you have time please @DavecUK it would be good to get your thoughts on the “best” settings

Below are what was set on my V1 and V2 Evo

No actual current issues I’m aware of, just curious 😻

sketchy

prezes Doing a bit more investigation on this, against what the default settings were (especially P & D), I’m suspecting the default PID settings paired with the capabilities of the boiler (size vs the mount it is heating) are to help prevent a more severe oscillation that may occur with the new settings. But I’m thrilled with being able to maintain steam boiler pressure better.

sketchy

prezes An update that you may be interested. After a little experimenting with my Vesuvius, I discovered something. My normal routine had been to just purge the steam wand long enough to get the water out. Even though the pressure and temp looked good shortly after this, it would drop down to an anemic 0.8bar. But then I noticed a more vigorous steam pressure as I was cleaning things up. So I changed my routine to purge the steam wand for a solid 8 seconds before I pull the shot. Once I begin steaming after the shot is pulled, I can always maintain a 1.1 or 1.2b through the completion of the steaming process.

DavecUK

sketchy I really thought the vacuum breaker already exited into the drip tray. Do you wanna check and make sure you haven’t got it wrong and trace the pipes.

sketchy

DavecUK Most certainly. Let me check when I have a chance. Thanks Dave.

Adrianmsmith

sketchy

It definitely does.

I’ve seen someone else say the same as you as it partly follows the same tube internally that’s used to fill the tank if you plumb it in….. comes from the solenoid. Easy too go cross eyed and follow the wrong pipe!!

JahLaza

I’ve noticed my Vesuvius wastes a lot of water to the drip tray for the first 20 seconds or so of each shot. Not like a dribble but a pretty big flow. I’m currently using the stock profile 1, which shoots up to 11 bar, not sure but don’t ‘think’ it wasted this much water before I’ll try get a video next shot, but, does this sound right?

Edit: Here’s a video. Funny didn’t seem to waste as much this time but maybe someone can advise if even this amount is normal? I’m also noticing a lot more water on top of the puck but that may be bean related

I believe the water is coming from the vent valve not the expansion valve, at least that’s what it looked like to me on the video. A few questions, so I can help you.

How old is it, from new.
Sounds like it didn’t always do it, when did it start (or you first notice it
The vent valves usually open at 11.5 to 12.5 bar as that’s when the spring pressure is finally overcome
When did you last backflush it and do you backflush it properly.

Adrianmsmith

I’d assume 11 bars is opening the over pressure and venting in to the tray as it should.

To confirm, use a profile at 8 bars and see how it goes

Ramp up to 8.5, 9, 9.5 etc until the bypass opens and consider resetting the over pressure valve if you require a shot at 11 bars.

11 bars is on the high side of "normal’ for the Vesuvius so adjustment may be the order if the day to settle it down.

A better video showing where the water is flowing from clearer would help 😜🫣🙃

JahLaza

Adrianmsmith hi Adrian, I can try this tomorrow but this seems to have developed recently, I’ve used this profile without this issue for a long time. DavecUK I will try get a better video in the morning

JahLaza

DavecUK hi Dave, thanks for chiming in

It is a march 2022 model I bought from new when Paolo gave us a deal on here
Only noticed it the last couple of weeks or so
I backflush with blank disc/water every three or four days and with pulycaff every three weeks maybe
I make about 4 to 5 coffees a day with it
I last back flushed with pulycaff last week. I back flush with blank disc and water a couple of times first to get rid of any free debris. I then back flush with pullycaf by pressurising to approx 5 bar,release pressure, wait about 20/30 seconds repeat. I repeat this about 4 times then clean blank basket and repeat the above flushing steps with water. This is a procedure I found on tapatalk I think that you had suggested for the Vesuvius
I also observed the vent movement of the lever was very stiff after regreasing with molycote after this procedure last week. I disassembled the release chamber (bottom part?) of the group head to see if anything was sticking or any dirt there but didn’t see anything. Still stiff when I lower the lever at the end of the shot. Just adding this in case it could coincide with the stated problem
