ACS Vesuvius Evo Leva

Cuprajake

I used filtered water or water with a custom recipe. However I opened the machine up today and found scale on the underside of the serviceboiler, as well as rust on the grill on the underside of the Evo. It just keeps on getting worse I guess. I’m currently descaling to see if this helps.

Thanks for the suggestion. I looked after it, but this was not the case.

DavecUK

Thanks so much for the effort! I’m based in Germany and will get in contact with ACS.

If you have scale then that may be the issue, or it had a small leak under the boiler and the drip has caused a dust spot.

All machines can get it.

What is your water, after the descale maybe change it up

deiadri

For sure going back to my custom water recipe which I used to use in the beginning. Just went on a nightly walk to the supermarket and bought 10 liters of distilled water.

So I did the following:

I read some posts ago that the frequent activation of the pump can be due to pressure getting lost from the brew circuit. I switched off the service boiler and the pump activations just continued, so I guess this could be the case.
Also read that adjusting the pressurestat helped somebody to fix this problem. I turned the screw ¼ turn clockwise and the frequency dropped to about 4-5 minutes. However preinfusion was still around 4 bars. I then choked the machine with a shot and adjusted the pressure downwards until I hit 2 bars again. I’ve been waiting for 15 minutes now and no pump activation until now. Very nice.

I will finish the descaling and and then reseal every Seal and screw I see scale on from the outside.

While doing all this I noticed that a drop comes from the shower screen every few seconds, so I guess the group needs now seals. Can somebody give me a link where I can buy the fitting ones?

Thanks to everybody already

deiadri Does the water drip from the group all of the time or just when going through the heating up process? It is quite normal apparently to drip when heating up (someone did explain why but I have forgotten). Every now and again, mine goes through a period where it drips for an hour or so when warm then stops

DavecUK

deiadri Group has an open chamber, so what dfk says is completely correct. It can also happen after a shot for a while.

Has anyone found a good fit black dosing funnel.

I really like the Sworksdesign 55MM magnetic funnel I purchased.

Changing steam tip from 3 hole (from factory) to the supplied 2 hole BUT it’s different, factory one is (left side) has a small tube attached to it, the spare part 2 hole one doesn’t, am I suppose to pull that tube out?

Also, the touchscreen, is it me, am I doing something wrong…. The Accept/Tick….. Its so hard to execute it.

I’ve tried… light touch, firmer touch, touch and hold 2sec, touch and hold 5 secs..

It’s a hit and miss, longest I spent trying to execute a change in brew temp was 30secs tapping on the accept/yes

Rest of the screen seems ok

Elcarajillo

It is to allow a ‘cool wand’ tube to be fitted over. Some cool wand tubes fit over others fit inside the tip.

@boshk

Regarding the LCD sensitivity issue, this is an issue which others have experienced too. How to resolve it is explained for instance on page 52 of the EVO (Unofficial) FAQ in my signature.

Good luck with it

boshk

Eiffel maybe I’ll skip that little part for now…..just got the machine, havent even dialed my grinder in for the 54mm basket, only so much I can/should drink in a day

Cuprajake

my screen felt buggy now its smooth, you will get used to it

Petre

got some noob questions about the machine, I’m curious why a 54mm portafilter was chosen instead of the more common 58 in case anyone knows, and also how do you find 54 compared with 58

Cuprajake

Initially it was wierd, felt smaller and basket prep was harder

But once you get used to it it’s fine

A good tamper helps and most users move over to the ims competition baskets

Interns if the group size you’d have to ask LSM I suppose I know @DavecUK highly rates the 54mm group over that of the 58mm levers.

Amberale

A lot of traditional levers have baskets smaller than 58.
Caravel = 43
Cremina = 49
La Pavoni = 49
Strietman = 50
Faema = 51

There is a generally accepted theory that the deeper/narrower baskets are more forgiving of puck prep and (possibly) give a better extraction.

MediumRoastSteam

Amberale - not only levers.

La Spaziale group is 53mm. This is a very traditional and popular machine in a commercial environment.

Sage/Breville mid range machines are 54mm.

La Pavoni lever group has grown in size to 51mm 23 years ago.

Ponte Vecchio lever group is 45mm.

Lelit make machines with a 57mm group…. Same as Ascaso, but not sure they still make them or moved to 58mm.

I read something somewhere that only reason 58mm is popular is due to the Faema E61 group once the patent ran out and clones started appearing, and hen the increasing popularity of pumped heat exchanger machines.

Petre

Do you usually dose less in a 54mm than in a 58mm or the same? What’s the most common dose people use for medium roasts?

DavecUK

Petre I dose exactly the same.

Amberale

Petre
The smaller diameter baskets are usually deeper so you dose the same and have a deeper puck for the water to go through.

Cuprajake

same dose
