KPc = 0.2 (PID Proportional value coffee boiler)
KIc = 0.07 (PID Integral value coffee boiler)
These settings on mine are much different to Dave’s. I found another value which was very different (Bs) and set it to Dave’s. It seems to get even hotter now
erkal -
Can you please list ALL the values here, of all parameters, please? The derivative and band/range values are also important. (e.g.: KDc and Bc), as well as the offset value (EC). And same again for the Steam values, so KPs, KIs, KDs, Bs, Es)
Many thanks.
Sure, here we go:
KPc 2.0, Klc 0.04, KDc 1.0, Bc 30, KPs 2.0, Kls 0.00, KDs 0.0, Bs 1, Ec 10, Es 0, F01 1, TR 1, ToT., EVS 1, BLS1 3, BLS2 3, BLP1 2, BLP2 5, PRG 3
What do you think?
erkal - Well…
erkal I believe, copied from Dave’s settings.
I think you haven’t copied the settings as suggested by @DavecUK :-)
See below, key in the correct values and we go from there :-) (e.g.: KPc should be 0.2, KIc should be 0.07)

Let me know if that fixes the issue :-)
Right! This is pretty perfect now, thank you so much for your help!
I don’t know why I didn’t think I could change the initial values, totally my stupidity, I have adhd and reading instructions doesn’t always lead me to the intended result :)
I pulled a shot and it dropped to about 88 and slowly creeped back up (about 30-40s) and its lingering around 93-94 now. Never went above the set value of 94. I guess this is what we wanted?
Now I just need to upgrade my grinder, get a bottomless portafilter and I will be rocking, get out the way James Hoffman!
erkal Good stuff. I’ve tried many different settings before, but just kept coming back to these ones. Give it a go, see how it works for you.
Enjoy the machine and have fun in choosing all the accessories!
Hello again,
So it seems I have a new problem now which I cannot decide whether if its the Elizabeth or my grinder. But it seems that when I pull back to back shots, the second one always seems to run faster.
I use my scales to measure the time/weight manually in the hopes that I can repeat it by setting one of the programmable buttons to the same time length, yet this hardly ever works.
For example, I have just measured a pretty decent tasting shot which took about 33s to yield 38g of espresso. I record 33s on button 2 and then set up a second shot, press button 2 and I get about 54g of espresso.
Where do you think the issue is?
Thanks!
PS. I have a Baratza Encore with the Virtuoso burrs which are relatively new (replaced them about 1.5 years ago)
erkal But it seems that when I pull back to back shots, the second one always seems to run faster.
Try flushing the machine for a couple of seconds - until water comes our of the group - before your shots. I found that for the first shot, it takes approx. 2 seconds for water to drip from the shower screen once the button is pressed. - Which could be leading to your slower first shot.
Saying that, I had a similar issue with my Profitec 700 back in the day. Annoying as it is for the perfectionist, I wouldn’t loose any sleep over it.
So how do you make consistent shots? Do you weigh every single time? About 10g extra water at similar timeframe is quite a big change in taste as well
erkal So how do you make consistent shots?
forget timed buttons. Weigh in, weigh out.
Ahh OK. That’s a shame as I chose this machine part for the timed buttons so the others in the house who don’t know much can easily pull programmed shots. Bit of a let down then :/
Anyway thanks again for the tips!
you can work off time, but get better results weighing.
are the other users milk drinkers
Decent De1pro v1.45 - Niche Duo - Niche Zero - Decent is the best machine ever made -
i wouldnt worry too much bud, as long as you are there or there about’s you will be fine,
i have the grinder set for the mrs brew, she knows the dose so grinds and tamps, on the lever she moved the cup at 8bars, and on the bianca i tell her 30s she has milk in hers but she gets 16.5g in 30g ish out
Decent De1pro v1.45 - Niche Duo - Niche Zero - Decent is the best machine ever made -
no, dual boilers much better - you did right
people just get ate up chasing perfection when theres so much variability in coffee

erkal - Unless you have a fully controlled and stable environment, a grinder that is 100% consistent and a coffee that never ages.
So it’s said that, for consistency, it’s best to control the ratio of the beverage over a period of time, but just roughly. Of course you don’t want for your 18g in, 36g out to last 50s nor 20s. But something between 30s and 35s is acceptable.
Maybe a Sage/Breville Dual boiler would have been a better choice for you, as it has volumetric capabilities. Saying that, I have no idea how accurate that volumetric flow controller is.
erkal Hey! No unfortunately not. They are Americano drinkers. I cannot believe that the whole programming feature of these machines is just a fake gimmick. Why even bother putting these features in if they cannot work with consistency
There are 3 other sources of inconsistency not being mentioned
If you do everything the same and are consistent in the 3 things above, then the volumetrics on the buttons should be right be within a couple of seconds or so.
Keep an eye on pressure gauge also, readings must be different also between first and second shot. Pretty much we all had some sort of inconsistent pressure between first and second shots with Elizabeth.
I have sent the upgraded opv but i never installed it, what i do now i place blind filter and run pump up to 30 seconds when machine is warmed up, then wait 1min to get it up to temp again. This is how overcame this inconsistency problem.

This was a jamming expansion valve in earlier models, this is a late model one isn’t it?
