MuddyOne - for reference on my coffee today. It was from Darkwoods - Crow Tree. Medium dark. Roasted 11 December - I’ve been drinking this over the past week. Seems to be a blend of American coffee (Peru, Bolivia, Colombia and Honduras)
Machine: Lelit Elizabeth (vibe pump, slower ramp up)
Grinder: Niche Duo, setting 7.
Basket: VST 20g
Dose: 19g
Pressure: 10 bar -> 9 bar (noble infusion)
At 8s, starts dripping. Shot finishes at 33s, 38g out.
I already ordered another bag of red brick as per other suggestions, I wonder, only wonder if adjusting off set to negative value would fix the overheating problem. I mean there is a reason why negative off set exists right?
Still I will hit b&q and screwfix tomorrow and see if I can wired thermometer before ordering online.
Sorry if ive missed it any you already posted but, have you got a video showing your situation, steam etc.

Yeah I think it’s been auto deleted after couple days.
That steaming is happening above 92 degrees with off set at 2. It does not happen after 30 minutes of turning on machine,rather after 1h. 10s after putting lever up usually gets back to normal.
Ok, so assuming your kitchen isnt at 5 degrees C and 80 percent humidity ( 😘 ) i see what you mean.
Have you checked that water temp with milk thermometer as it runs in the cup.
Dont forget especially if tou get a “cheap” thermometer to “calibrate ” it at 99.99 degrees 😎

Adrianmsmith I will get thermometer tomorrow, I have milk one but it’s not calibrated lol :)
MuddyOne wait wait wait!
Your machine… You said it was at 94C…
But look closely at the video before it starts drawing water… It reads 97C? Could this be the cause of the steam?
What’s going on?
Yeah , it was for the most part.
Then I’ve been doing some more testing, I’ve been setting machine to 90,91 degrees as stated above the problem is no longer there around these temperatures. Then I set temp to 97 to see if even less water and more steam will be coming out, I just uploaded one random video to show the issue, temperature is set to 94 degrees with +2 off set for most of the time.
And another update, just had my machine on for over hour but set off set to -4 with 94 and the issue is not here anymore.
What is the manufacturers suggested offset for that machine.
They’ve usually calculated what is required for proper operation at the group .
Also, What do you mean by offset is +2 “for most of the time”

Cuprajake sorry I owe you apologies then, I through all comments again and I honestly missed your link you posted, in avalanche of comments it happened.
Well I have two questions then, my machine allows only to be set to 99 not 100 degrees , is that ok for this calibration?
I assume that off set setting in that case should be set to zero?
I meant that temperature is set to 94 for most of the time.
Off set is by default to +2 .
Yeah, .
For me temp or more temp stability is key,
Unless you have a scace device you will never know for certain what the temp is
But like grind size as long as you can assign a number to that setting, and it’s repeatable, it’s just a number.
Once you sort your temp it could be something a simple as that, while I still think it’s the beans
Go back to basics, get temp sorted use the stock basket, it will allow a coarser grind, put the vst in the drawer for a while. Get a repeatably prep system and go from there, even if it means buying 2kg of the same bean to get used to what your changes do.
I’ve never been a massive fan of square mile.
Decent De1pro v1.45 - Niche Duo - Niche Zero - Decent is the best machine ever made -
The only info i have without a Google is for the synchronika . Do you have the similar info for your machine?
So for the synchronika the offset is set at 15 degrees C by ECM. I once did a video showing how good the syncka was but cant find it now . I never had reason to change the manufacturers settings .
What was yours originally set at.
I will say again for clarity the below is for synchronika

I mean such device with wires is not that expensive , 20-30£ unless it’s not accurate in that price range. I can also always borrow one from my workplace we use them .
If that is correct then my off set is meant to be -6 at -5 it already starts flash boiling and you can hear paper tearing/steam sound.
Adrianmsmith - you’ve missed a few posts :) - most likely in the other thread.
Essentially… ECM/Profitec in their infinite wisdom have decided to pre-code an offset in the machine. What’s wrong with zero? But no… let’s just think of a value and add there… 42 anyone? In Fahrenheit maybe? 🫠The user can now add or subtract 10 from whatever their preset offset is. And yep… your guess is as good as mine on what this pre-coded offset is…

Read on… 🥳
Adrianmsmith no I haven’t found such info in manual , just this . It says the default value is 0 but mine came with +2
MuddyOne I mean such device with wires is not that expensive
As Jake said, you’ll have an idea… but it will be by no means accurate. Just google Scace-II device.
And as Jake said, it’s just a number. It matters not. But your machine should not be overheating after being idle for 1 hour. It’s not an HX machine. You might reduce the temp, but it might mean your water is now too cold at the start (I.e: sour coffee).
Your retailer should test your machine with a scace device and go from there.
