ACS Vesuvius Evo Leva

LMSC He is saying the opposite, it leaks when fully cocked and pump is running, but not when he releases the lever.

LMSC How likely a faulty inlet port valve could be responsible for this?

Not likely at all from his most recent description.

Ok. That’s what he said last week and in the earlier post. The “not when the shot confused me a bit!”. Thx

DavecUK

LMSC I’m not sure what the problem is either?

LMSC

DavecUK Please see the green oval? What’s inside this area please ? I don’t know.

The metal pin comes into contact with the small lever — after the lever is locked down. Is it an open chamber or a pipe where water rushes to the inlet valve? A wild thinking is, is there a chance, when something is faulty here (inside the chamber of the green oval circle), the water is straightaway pushed up through the back of the group. Don’t laugh at me! 😁

Edit :

It would also mean a faulty O ring - my point 3.

A valve, which feeds only the water jacket of the steel wet liner and exits at the bottom of the group, below the piston.

Thanks Dave 🍻

spool hi Jacob

In happy that in some way you are satisfied with one of our machines. It could be useful also for us if you will share with the company the problem that you have found before to find a solution somewhere. Can you email me at p.cortese@elcor.it with your serial number and if you want send me the problem that you have found on this machine, it will be very helpful for us to improve our production and testing. Many thanks.

Paolo

Camby No probs, it is a super easy fix but feel free to DM or ask here if you need any help doing it. Maria at ACS was also very quick and helpful getting me set on fixing this. I would suggest using the smallest magnetic screwdriver you can find, as the space to adjust the screws and take the clear cover off is very small.

pipedreams86 Maria is great! 😀

@danielpugh is the leak past the piston when it’s at the top of it’s stroke and the pump is running resolved now?

Hi All, quick update - some seals and o-rings arrived from Paolo which i have just fitted. Much touching of wood, but 6 shots without leaks so far. Relevant info which may be of use…

i replaced both the lower gasket, the upper o-ring and the teflon bit.
to replace the upper o-ring you do not need to unscrew the springs.

Wish i had known as scratched the chrome as had to use a vise, only to realise the whole part comes out with the o-ring embedded. To remove the o-ring you just lever out with e.g. a screwdriver.
the new main gasket has a much bigger lip than my original two or the two i got as i had used the spare from ferrari espresso. so there does seem to be signficant variablity which is strange - (these were ones i got - https://www.ferrari-espresso.com/product/izzo-my-way-leva-piston-seals-x-2/).
i could see very little wrong with the o-ring apart from it seemed to have oil behind it which may be a factor. After replacing i used a thin coat of moly 111, and the same on the other gasket.
Having removed the part that holds the spring, i screwed up till it hit resistance. Not particularly tight but firm, and obviously not meant to go further - not sure if that is good or bad.

so in all the cause of the leak is a mystery, but fingers crossed gone.

next minor job is to fix the wonky steam connection - hoping this job is easier

DavecUK

danielpugh The leak was the main seal…the O ring is not for holding back water under pressure like that. Makes me wonder if somehow and incorrect main seal was fitted and supplied….who knows. Just glad for you that it’s sorted.

LMSC

danielpugh Glad you fixed the problem. It’s a mystery. However, as Dave said, unless the lower gasket, which I think you call it as a main gasket, is weaker, the water can’t shoot up. Now, you can concentrate on fixing the steam wand, install the RO and fall in love with her again. 👌

danielpugh

@LMSC always been loving, no change there, just slightly cursed with poor luck/minor problems. I know I can generally fix mechanical stuff like I’ve had. Would be good to isolate a source of good gasket versions as I have 4 that seem slightly wrong, and one that just arrived that seems to flare out more. Could be my imagination though…

DavecUK

danielpugh I’m wondering to get a big box of em from {Paolo and then people can buy them from me for no profit….what they cost), plus a self addressed envelope, or whatever. I would think as long as they stay flat should only need a first class envelope…I dunno.

LMSC

danielpugh Glad you said that Daniel. So, the Ferrari link the correct fit? Is that for the lower gasket ?

LMSC

DavecUK Good idea Dave. I think getting the critical wear and tear parts bulk from Paolo is necessary. You can then send it to us, if that’s not too much trouble.

DavecUK

LMSC You can then send it to us, if that’s not too much trouble.

Well, it would be unless the self addressed, stamped envelope thing pans out….Then I can just pop a couple of seals in.

danielpugh

@LMSC the ones from Ferrari were like the ones that came with the machine. @Paolo_Cortese sent some new parts and they seem(ed) to go outward more to my eye. Maybe it’s just my machine or my imagination, or perhaps a specific version. Unsure

DavecUK

danielpugh Paolo probably gets his direct from the group manufacturer.
