ACS Vesuvius Evo Leva

Finley-72

DavecUK Thx Dave. After reading Jake’s reply I figured it did. When I had the machine in for service perhaps it was adjusted? Not sure but I will report it. I will carefully and slightly adjust the stat and get back to you. I don’t remember it being a problem before. It perhaps did this occasionally , but if so it was infrequent since I didn’t notice it as an issue.

The dead band screws feel loose in there but they turn. Take a good before pic so you can go back.

Finley-72

DavecUK I adjusted the dead band screw counter clockwise towards the +. It’s now horizontal if you look into the machine. It has worked so the machine only pulses occasionally and I think it is likely due to water seeping/creeping in the group while sitting idle at temperature. I’m looking into whether the shop adjusted it for whatever reason. Thx Dave and Jake for your time and help.

Finley-72 It has worked so the machine only pulses occasionally

What do you mean by occasionally?

Finley-72

DavecUK I did speak to soon. I did adjust the pressure stat screw. I’ll attach before and after pics. It is pump pulses every minute with both boilers and very 2 minutes with just the brew boiler. This is better than before. Basically whenever either boiler clicks to begin heating or rather maintaining it triggers the pump to pulse. Should I adjust the screw counter clockwise more?

DavecUK

No, there is a different problem. The sealed brew circuit must have a slow leak, contact ACS for advice.

I’ve also no idea why it pulses more often with the steam boiler on, and less with the steam boiler off. Be sure to mention that in your email to ACS. It could be as simple as something like the one-way valve in the water distribution circuit.

Cuprajake

Yeah sounds like a leak somewhere.

How does it react to filling the group when making a shot now?

OrangeBubblegum

Seem to still be getting this error (AL11). Ive checked the setting and F=4 is 0.

Does the sensor detect if its in water or not? Or just by the positioning of the ring? (Up = tank has water, down= tank is empty)?

Cuprajake

You may have a dodgy wire, I did.

The wire from the sensor goes down behind the boiler, and is cable tied up to the frame, one of the cables had come out of the connector, yours could be the same

It’s only 2 wires, the float just joins them to say there’s water.

Take the back off , then the weight and trace the wire back.

OrangeBubblegum

Cuprajake Do I need to take both the top and back off? Which tools do I need?

Eiffel Hi, a bit off topic, but I can’t seem to be able to access the evo leva faq that you link below (and I was able to about a month ago). Since I’ve asked ACS for a quote on an evo leva, I just wanted to check the faq. Would you mind checking accessibility? Highly appreciated!

Eiffel

I’m not sure what happened, but this new link (here or in my signature) should work.

The FAQ hasn’t been updated for nearly 18 months (someone else volunteered to do it), but what has come up in the interim seems to be only positive, setting aside the price increase… and my own Evo Leva continues to meet expectations and to work flawlessly. The Vostok 1G and upcoming Evo Leva V2 (assuming it has the same features as the Vostok 1G) may have more convenience features, but the in the cup results shouldn’t be any better 😉

Nuttybarista

Eiffel Yes, it works! Thanks

Cuprajake

yeah top and the back,

there are 4 allen hex bolts on top, for the lid,

then there are 2 top and 2 bottom holding the back on,

the counter weight is Phillips screws, be careful, this is heavier than you think, and its stuck into the screw threads so you may have to give it a pull away from the machine,

the connector is then on the right near the boiler

Grahamsphillips

Anyone recognise this Machine??

DavecUK

Grahamsphillips I do….well done, you made the right choice.

Grahamsphillips

Yeah. I’ve really enjoyed playing with the L1 but this is a completely different class. No to read the full thread!

Cuprajake

It’s a cracking machine, enjoy 😃

Grahamsphillips

Yeah it really is Jake. I can see how @DavecUK expertise has helped shape a magnificent machine and you’ve added a few artistic accoutrements! Looks stunning. So now I have a Vesuvius and an EVO for side by side comparisons! I’m like a kid with a new toy. It’s pathetic!

Grahamsphillips

Hi Evo peeps! So I’ve got the basic hang of the machine.. so now I want to learn how to fine tune it. I’ve downloaded and read the manual (truly I have) but I’d really value users’ experience and @DavecUK expertise in fine tuning. I drink almost black double-espresso (medium and light roasts) 99% of the time. All recommendations and advice welcome… TIA! Graham

dfk41

Grahamsphillips The first port of call is to get the right temps set for the group heaters and brew boiler. I as you know, drink darker roasts than you and I have mine set at 93/98. Light roasts will be higher but others will chip in
