Dave you wrote

"“No, machines will function correctly on water with a TDS of 3%, this is true of all machines. RODI which has 0% will probably function as well, but I have never used RODI water.”"

Did you not review a countertop RO system called Osmio in a YouTube video - did you not mention you used that RO water in a Vesuvius E61 for 4 years - or did I miss understand ?

Thx fir all your help

selmerfudd Your point being??

Note the word No has a comma after it and is an answer to a question you asked.!

Patrick

Oh Sorry - how did you manage to use RO water at less than 3% TDS and have the water probes to function correctly - I was under the impression that “boiler water level probes” need mineral content to function correctly - ?

Can I use distilled or demineralized water in my Leva Evo II ?? Or do I need to add minerals to it ?

Again thanks

Cuprajake

No, it’s corrosive

Use something like Dr pavlis

Or just plain ro water it usually has 30-70 TDs

Distilled or rodi will more likely not work

Cuprajake

To add if you are concerned about scale etc use the lowest TDs water you can like pavlis then use drops post brew to alter the taste. Alot of the decent lot do that

selmerfudd

As of now I use distilled water with additional third wave packets to make up for the lack of minerals -

my DE1 can function without the added minerals , since there is no boiler involved however for taste i add the mineral content anyway !

thx

selmerfudd My questions

1- How come the safety system only works when the machine is turned on I thought it was a passive system not active?

This may be of use to you .

Yes the mod is indeed interesting-Thank you– I am new to the Coffeetime forum, so many of the discussions i have not yet perused .

I also was concerned about the lower pressure attained with the safety system - as well as the overall weight discrepancy on the puck between 9 bar at 54mm and 9 bar at 58mm , well I managed to obtain 11.7 bar with safety ,close enough !

I still want to experiment with the flush lever pre charge and pre infusion , but so far I have not spent much time studying how to best use the flush system - to see what benefits it could yield.

thanks again interesting reading for sure

First off im not suggesting anyone does the mod, it was more to show you how it works…..

As for pre charge the best way is to set the flush lever so the pump engages as soon as you move the lever.

Make sure you move the lever to the pump on point . Pause until the pump starts

Get used to the speed required to move the lever so the pump stays on and you do not hit pre infusion pressure until the lever is at the bottom.

Why……..

By doing the above you will have very little air in the cylinder, only water.

So what……

This will give maximum pressure as air is easier to compress .

Im not buying in to the need to go past 11 bars . Some people mod to lighter springs to achieve lower start pressures as they want 9 or 10 bars max.

Psi is psi , or bar, at 20mm or 58mm.

Kg dead weight will give lower psi at 58mm and 54mm

As for the mod I understood it was simply to show the workings

How long have u had yours ?

Adrianmsmith

selmerfudd

I purchased this very early on. Its No2, originally purchased by Jake. (Dave has No1)

Prior to that i had Evo1 and Vesuvius after realising the ECM Synchronika was not the holy grail!!

Jakes, my coffee journey would be a good read when you have time ….

@selmerfudd

……

There you go .

Alternatively You can easily achieve any start pressure you want by putting very slight pressure on the lever after it settles.

@Patrick Just for you, you will see the standard ACS flush lever arm is fitted 😎

I had reached out to Jake on youtube, prior to ordering my Leva II - he mentioned selling his machine early on due to issues! I also know that dealers are not enamored with ACS and not interested in their machines , i.e. Chris’ Coffee not wanting to bring in the Leva . My friend in Canada advised that the ACS dealer there dropped ACS for quality issues.

I might be out to lunch but it seems to me that somehow much of ( not all of course ) espresso is still in “cottage industry phase” with smallish builders with limited budgets developing and building machines. This drives costs up significantly , resulting in machines costing twice that of a full fledged fridge as example, not to mention the less than rigorous testing and quality control required for a consumer commodity product these days. Whether Decent or ACS and many others , it seems the real testers are the original buyers as was Jake and others.

I wish this industry had reached the “commodity stage” , with more realistic pricing, as are many appliances like the price of today’s microwaves compared to 2 decades ago!

I would like if some LEVA II owners chime in to comment on the consensus of the in cup result of the Leva II VS a DE1 ??

thanks to all who comment

selmerfudd Am I going to be the first to cast doubts on the Decent? OK then, here goes……….you are buying some very clever software paired to a really cheap nasty vibe pump machine. You cannot mend them without sending them half around the world (just as well they do not weigh much). If Decent go out of business then you are stuffed (remembering the Decent is a failed crowdfunding machine to begin with). How many coffee afficianados really want to conduct a laboratory experiment every time they make a coffee. Yes, I hear howls of derision from all the Decent owners who feel they have the ultimate bit of kit (yes I agree, it is ridiculously overpriced). Bring it on!

PS I am a Leva 1 owner not a 2, so please feel free to disregard my rant

selmerfudd

OK ,, well i kept it to myself but I have owned two Decent machines a 1.42 and a 1.45 my experience has been sort of OK but what I really need is mouthfeel in espresso and somehow Decent cant seem to get this right , whether reducing head space or whatever i tried i never got a sumptuous cup of coffee.

As for the claim that the DE1 temp probe is right at the coffee slurry is really a red herring , the DE1 does indeed measure at the slurry but then corrects temperature discrepancies way behind in the water mixing manifold ! - The front probe never sees the corrected temperature to the slurry until its too late , ( in my opinion of course ) .

Any manufacturer can go out of business , especially the smaller ones as is ACS , and many others

Or worse decide to no longer play in the espresso game !

Why anyone would buy a Nurri at this stage for example is beyond my ability to comprehend !

Worse is the looks of some of these machines - boy are they rudimentary .

But here we are liking our hobbies to the point that we will even work for manufacturers at no cost to them when we agree to fix their problems ourselves ! Imagine if GM had this luxury !!

Agree but they tend to use fairly standard industry parts so that their machines can live on.

selmerfudd

dfk41

that is Decent’s claim as well off the shelf parts !

dfk41

selmerfudd Whose shelf though?

Oh I am not a Decent fanatic so im not promoting them in any way
