I can’t seem to get rid of unpleasant harshness and dryness

MMuddyOne · 24 Jan

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 ……

MMuddyOne · 2 Feb

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?

Adrianmsmith · 6 Feb

Have you tested your actual water temperature to see if that actually is your issue.

MMuddyOne · 6 Feb

acopl the machine should be with me tomorrow, you need to test if temperature is stable. Perhaps your boiler probe is bad too

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?

MediumRoastSteam · 10 Feb

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.

Adrianmsmith · 10 Feb

MediumRoastSteam

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 🤭🤔

Aacopl · 10 Feb

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.

Adrianmsmith · 10 Feb

acopl

How are you checking the actual water temperature 🌡️?

MediumRoastSteam · 10 Feb

@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.

MediumRoastSteam

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!

Aacopl · 10 Feb

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”…. 😋

RRaja123 · 16 Feb

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.

JJason1wood · 16 Feb

I always taste my espresso before adding to milk, even if it tastes rank, the steamed milk makes it taste delicious 🤣

Ok so I finally received my machine couple weeks ago, with all the mess with their broken device,Christmas period and all they had it for about a month.

Probe been changed and off set adjusted to -2. I have been testing temperature at couple different occasions.

I’m getting accurate temperature now but will keep an eye on how it behaves , they also said the pressure was fine.

I still can’t get 1:2 in 30s , 27 s is closest and then machine starts “ choking “ and extraction starts late.

I forgot to mention earlier that I have replaced screen to ims competition, if that makes much difference, I’m using darkwoods barrel aged coffee.
