Adrianmsmith yeah I think something is wrong with the machine and it’s not offset , look I set off set to minus 3 and turned on machine (it started heating up from 25 degrees since last time I turned it on) after 25 minutes it reached only 84 degrees, then pid showed it dropped to 79 degrees in 30 seconds.
Second video I tested after 1h of turning it on, it reached 93-94 degrees but not 95 , something is wrong with the pid here:(
Any updates?
Yeah, I was going to make a summary of updates once the machine gets back to me.
Seller accepted that something is wrong, got my machine posted two weeks ago, they are sending me updates, one that temperature was unstable and they narrowed down the issue to ntc probe and fitted a new one, then they wanted to keep machine for couple more days for testing. I also asked to check the pressure as something didn’t seem to be right there too.
Couple days ago I got another update saying that they are back and forth with profitec but they are slow to reply and on top of that their thermocouple has broken and they are now waiting for a replacement. That’s all for now, they did not give me the reason of communicating back and forth with profitec though.
My machine should come next week, they just sent me an email saying that after thorough testing they are now happy with stable temperature, espresso been delicious and consistent, they’ve been replicating shots. Also the pressure is stable. My machine should arrive soon, once we both agree on date of delivery . I’ll run some tests and see how things taste, hopefully no more harshness
It would be good to see a list of what they have done and replaced ……

Adrianmsmith they only have told me that ntc probe was replaced and temperature been stable when left for long periods of time, also off set been set to minus 2 as the temperature been showing 4 degrees higher of what been set.
I just sent them an email to confirm if that’s all the work that has been done 👍
Hey, I’ve experienced a similar issue as yours; I can’t seem to get a good espresso from this machine. My current setting is 90°C with an offset of -2°C.
Do you have any updates on whether the machine has been fixed?
Have you tested your actual water temperature to see if that actually is your issue.

Hey, after conducting a few tests, I found that setting the temperature offset to -1c/-2c gave me the correct brew head temperature.
However, even at 93°C, I couldn’t get a tasty espresso. I’ve since dropped it to 86°C, and it’s much better now.
How about you? What’s your brew head temperature?
acopl - Your machine must have a problem then. It’s just not normal to have espresso extracted with the brew head temperature being at 86C.
is he saying that is what the temperature is set at or is that the actual water temperature.
If it is the water temperature, maybe it is the taster 🤭🤔

Hi guys, sorry for any confusion. I’m referring to the water temperature set on the machine, which seems quite accurate in matching the brew head water temperature as well.
I’ve adjusted the setting with an offset to -1/-2.
How are you checking the actual water temperature 🌡️?

@Adrianmsmith - Regardless… 86C on the display is not something normally seen on this sort of machine, unless you favour very under-extracted and sour espresso.
Or the machine is overheating and giving false readings… Or something else is off.
Exactly, but, what im asking is
Does it say 86 on the display
What is the actual water temp.
If that is 86 then the only issue is the beans!

Hi, I’m using a K-type thermocouple and placing the sensor inside the portafilter basket without any coffee grounds.
For espresso, I’m using medium-dark roasted beans.
Grinder: Niche Zero, 17 to 35 grams in 30 seconds.
Flow control to 8 ml/s.
This video should help with your technique.
Ive been referring to it for nine years to help perfect, everything ☕🤣
Happy sunday
…… I wonder who will be the first “with milk drinks it makes no difference”…. 😋

Gail is ace.
Regarding milk, my own experience is that I can still taste origin/the more potent flavor notes through it. On the flip side, it can also mask some of the unpleasant attributes of a shot. Maybe people abuse that second point, just to……put milk+coffee drinkers down, heh.
I always taste my espresso before adding to milk, even if it tastes rank, the steamed milk makes it taste delicious 🤣
