ACS Vesuvius Evo Leva

Adrianmsmith

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 🤪

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.

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

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.

Adrianmsmith I have a hissing sound coming exactly form the elbow fitting you have removed in that picture.

Currently managed to unscrew the nut, but stuck on getting the pipe out of the elbow, when I stumbled upon your post.

Do I understand you correctly that I need to loosen the boiler screws on the bottom and unscrew the nut of the other elbow to be able to get the pipe out of the leaking elbow?

Grunta

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!!!

Grunta

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

Ah OK, good you got it fixed. out of interest, im intrigued how you removed it, assuming my method was not necessary. Maybe the production units ae a different arrangement for the plumbing?

Grunta

There was just enough flex to very slowly get the pipe out of the fitting. As you say the plumbing maybe different on mine.

Adrianmsmith

Grunta

Thats good to know. I had to create the flex as described . Was otherwise rock solid 💪🏼 😁

Does anyone have a parts diagram for the boilers on the ACS evo leva2, I fixed my first hissing steam leak, but now I have another sound somewhere like the first hissing steam sound, but very hard to pinpoint it.

Paulo will have the cad of the boilers and their fittings, he should be able to send you a screenshot….send an e-mail to Maria, NOT Paolo.

I’m intrigued how that will help you when you have all the information you require with the machine right in front of you.

A steam leak is easier to find with the machine heating and cooling, not simply idling

Hi Dave. Do Paolo and Maria use the same email address?

Been waiting for a response from Paolo for a new vac breaker for the Vesuvius (not leva)

Grunta

Adrianmsmith I have been checking while it is on and hot, just helpful to have parts diagrams for the future.

LMSC

A dentist mirror or a tissue should help, if you haven’t already.

Grunta

LMSC I’ve tried all those, plus I have a long bendy inspection camera, it’s not bad at the moment, will have to take most of the covers off, but can’t be bothered at the moment.

With my slight leak the other month it was self healing once hot.

Only visible and leaking as it past 100 to 120 degrees.

Once it gets hot, to investigate, turn power off and open hot water outlet until it drains. Then start again……

Grunta How old is your machine (when was it manufactured), as although Jake is correct…he is only correct for earlier models. The Vostok has used compression fittings on the back of the steam/water arms for a while now, probably 6 months or so. The Evo doesn’t have space to allow the use of them.

P.S. Even before those dates of compression fittings (on Vostok), flexible sealant began to be used around 2 to 2.5 years ago which also makes the problem far less likely to occur. It was caused by the expansion and contraction of the metals and a permanent (non flexible threadlock). The semi permanent is not only much easier to remove, but is flexible which alleviates the problem.

Cuprajake

depending on the version it could be off the steam arm and that is a nightmare!!

DavecUK The date on my invoice is 8th of October 2024

Thinking of adding the flush lever to my Evo V1(anyone else done that mod?) and replacing the gauge as it’s sitting at 2 bar.

Would it be best to contact Maria at ACS to see if that’s possible and to place an order.

I find trying to locate their site a bit of a mystery and the odd time I’ve found it, have difficulty navigating it.
