Ok… some results then 👍😊
Please have a read of that Reddit thread I posted. There are two main takeaways: settings and flow rate. Read the whole thing and then see if anything could be applied to your scenario.
If you do change anything… just make a note of the change. You can’t break it. And everything is reversible. 👍
MediumRoastSteam I scrolled everything up and can’t find Reddit link can you post this again?;)

Adrianmsmith oh that was a link I thought a screenshot from conversations, forgive me :))
Damn scace devices are 500£+
I did changes to d1 from 8 to 11 and pp1 from 2.0 to 2.5 lets see what happens.
My first impression after one shot is that probably made temperature a little bit higher, at 93 degrees the steam sound is just louder , and it affected flow rate which is now bit slower , the shot that previously took 28 sec now took 33 I noticed slower flow from the first moments , but I’ll keep trying.
You need to take out some guess work and check the water temp at the group.
The current approach isnt healthy for your sanity or the machine 😎
Some people rake the piss out if using numbers and actual real data for everything. Well woo is wrong on that one!!
You Need some actual numbers .

Adrianmsmith I know I know that’s why I said that doing anything on my own is like that, the whole trial and error is pointless without proper instrument and spending 500£ in a scace device is not something I will do considering machine is under warranty and it’s retailer job to do so.

That’s right.
The PID numbers won’t change much. All it MIGHT do is stop the machine from overheating when idling, that’s all. As Adrian said, someone needs to take a look at your machine pragmatically. I hope the retailer can help you with that. The scary part is that you are not alone, and there are others, very clearly, struggling with a machine of such calibre. You shouldn’t be experiencing what you are experiencing. Looks like ECM/Profitec, whatever they did…. They managed to mess up somewhere.
You dont need that just to check water temp.
Yes that’s the ultimate.
i leave the Ferrari at home when going to Tesco!!
I realise you dont have anything to habd to use but a cheap one will do with a wire couple. Its not like you need it all day every day.
Can lend you my fluke if you want . I never use it.

Adrianmsmith Thanks ,I’ll get one from my work , it’s old device but I heard it’s very accurate. I used it in the past with sage barista touch and it gave me readings reported by other people who’s been testing temp .
I’ll report temperature in a couple days. 👍
MuddyOne - also, on that same Reddit thread, they talk about flow rates. The OP opted for a machine without the flow control valve and says the flow rate is crazy. Consider reducing your flow control valve by another quarter turn and see if that improve things (I.e: lengthen the shot by a couple of seconds) including taste.
MediumRoastSteam can you say whenever you get a chance how many ml your machine delivers in 10s?
Mine does about 100-110ml with one and a quarter turn- which is meant to be default for brewing.
MuddyOne Mine does about 100-110ml with one and a quarter turn- which is meant to be default for brewing
Mine is a vibe pump so likely to be very different.
11ml/s is what the OP says is good in that thread, so it looks like you are good. Apparently the OP’s machine delivered 17ml/s!
This is pretty much accepted as standard FOR A ROTARY PUMP ECM etc
11g per second so a can of coke , 330g in 30 seconds

Adrianmsmith so 110 in 10s which is precisely what is mine doing, seems alright.
I have posted another thread on home-barista I’m hoping for find another profitec drive user to share experience, there must be some out there.
MediumRoastSteam I just received an email from retailer basically telling me to adjust off set, pretty much to do what Jake with the link to instructions posted.
“ if you get flash boiling at 93 degrees set off set by minus 6”
How should I respond to this or just take the advice?
MuddyOne - Did you explain the problem, i.e.: that the flash boiling is only happening after the machine is left idling for a while?
MediumRoastSteam yeah I did , sent that email before Christmas break and they may have forgot about that fact. But I sent them a reminder now with screenshot of that email, and a video I recorded ( I didn’t record first video after 30 minutes)
Basically what we talked is now reflected on devices , I switched machine on , set to 95 put the wire into ports filter and after 30 minutes it showed 95 degrees, plus minus half degree. But after another 30 minutes it showed that :
I sent them this video and explained that 30 minutes after turning on it was showing 95 degrees, now 99.
MuddyOne - Excellent! I hope they “get it” (i.e.: how can a machine like fluctuate the temperature like that when idle?) - It’s a dual boiler machine, not an HX!
I hope you find resolution and that your retailer sees the problem (rather than pretend everything is just fine). And I hope you don’t hear the usual: “Oh, that’s just perfectly normal. I wouldn’t worry about that. Those machines need a cooling flush after being idle for longer than 30 minutes”. No, no, no. It’s a dual boiler. It should not behave like that.
Good luck.
