And now it’s gone again lol , it seems to be happening when steam boiler is working/charging, this weekend first time for some time I had milk drinks . I’ll keep an eye on what is happening, I just have no clue what is causing this.
Profited drive lever weird noise
One thing I didn’t mention is that I have also been replacing control board couple days ago, they sent me new one with new firmware as there was a bug with old one.
That sound is coming and going , if I keep lever up after 25-30s it’ll go away and water is pouring without any noise, anyone can help identify this?
MuddyOne - sorry what’s wrong?
Lol it’s normal behaviour?🤪
Well it’s similar to first video I posted above it’s steam /tearing paper noise when operating the group Lever unless I’m Suddenly over sensitive and overthinking after doing few maintenance tasks on my machine 🤪

MuddyOne - what’s the temperature, and offset? And to be clear, are you saying this only happens when steam boiler is on? And when that happens… how long as the machine been on for? (Answer the questions and I think I know what’s happening).
Temperature is 94 for red brick, offset 3,I will test if that happens only with steam boiler I have switched it off now and let I cool down ,then test. Machine been on for few hours had three coffees but yeah that wasn’t happening in first 30 minutes after turning on .
After 10 seconds it stops giving that sound like when brew temperature drops.

MuddyOne - ok. Yao me, it seems like your machine is overheating. Given it’s a new machine… i’d contact the retailer and let them sort it out. All that “German quality” hey….
When you say offset is 3… that”s strange. It should be 14 or so. Can you list the PID / machine settings here?
Is machine going into some sort of standby mode?
All I can think of:
- machine is overheating due to misconfiguration;
- machine is still in express warm up phase - water in the boiler is overheated;
- machine is waking up and performing some express warm up (not sure if that’s even a thing)
MediumRoastSteam machine is going into standby mode but it remains on , display floats . As mentioned above I have changed control board recently. Off set was 2 by default and fast heat is off… I have no other choice I’ll contact the retailer, thanks for everything.
- Edited
MuddyOne - no worries. As said before, an offset of 2, or 3 makes absolutely no sense.
Don’t you want to put the config values of the machine here before sending it back? Up to you, but it could be a simple setting tweak.
Also… if the machine goes on standby mode - what does that mean? Boiler temp goes down to 80C and then full blast to warm up again? I’ve got so many questions… 🤣
How to get these settings?
I mean it’s only a display standby so the Oled display won’t burn in, it’s between my coffees .
After I’m Done brewing for today I put it on regular standby where temperature starts dropping, but this been happening between my coffees so no the boilers were not charging up between that

MuddyOne - No, don’t put the machine back into fast heat up - that’s not what wanted you to do. I was just curious of the machine config settings - wondering if something is not quite right and the machine is overheating when left idling for a while. I’m not familiar with this new version of the machine, so anything I would do would be based on my own research rather than first-hand experience.
Anyway, good luck with trying to figure things out. It’s not the ideal experience when paying £2k for a machine. I’d expect it to just work, but it doesn’t seem to be how things work these days anymore, sadly.
When I had my Pro-700 back in 2014, the Gicar Box also had to be replaced 10 months in.
Edit: Ignore my offset comments, as well as flow control “fully open”: I did some research and looks like Profitec has changed the interface and parameters significantly so the offset now goes from -10 to +10 (whatever that means). Back in the day the offset would be the difference between the water temperature in the brew boiler and by the time it reaches the group. I don’t know what the numbers mean now. (https://www.home-barista.com/espresso-machines/profitec-drive-coffee-offset-correction-t92429.html)
On the Flow Control device… I forgot that on the ECM/Profitec ones you can actually do full turns, unlike the Bianca (hence why when I suggested fully open, I was thinking of the Bianca, rather than the Profitec one which means 1 ¼ turn in comparison as the OP correctly pointed out). (
MediumRoastSteam I didn’t mean to put machine in fast heat mode anyway, the pid settings which exactly you ask for?
Pre infusion is off, fast heat off, steam temp 128, brew temperature 94, off set 3, I think that’s all relevant information do you need anything else?
MuddyOne - Nope. All good. Thanks for that. The only other relevant thing I was thinking of would be the PID settings themselves - but I wouldn’t have a clue on how you tweak those in this new UI.
MediumRoastSteam I have sent a video to machina coffee now, it certainly looks like it’s overheating. I put lever up and you get hissing sound and decent amount of steam from group head, once the sound is gone I put lever down and notice the temperature just dropped to 88-89 degrees. So that sound seems only to happen above these temperatures…. So that means it’s not a leak from wrong placed spindle /cam .
MuddyOne - I don’t think it would make a difference, but did you try with the steam boiler off?
Yeah I allowed steam boiler to drop to 98 before I tried again, same thing. I can try again once I’m back the machine and boiler will fully cool down I will leave it on with brew boiler only for 40 minutes and see what happens.
MediumRoastSteam Profitec has changed the interface and parameters significantly so the offset now goes from -10 to +10 (whatever that means).
I think they probably used the same system on the ECM Barista Max…. this they made +/-5
There is a built in offset, which could can then vary by -/+ 1 C up to 10C difference.
e.g. if the built in offset is 10 and you put in +3, then it changes to 13 for hotter brew temperatures (for any given temp set on the display). Conversely if you change it to -3, it changes the offset to 10, for cooler brew temps (for any given temp set on the display)

DavecUK - I just don’t understand why they make things complicated… there’s no difference in having the setting go from -30 to +30 (with no “built in” offset as a starting point). Why make things more obscure and complicated when they don’t need to be. 🤷♂️

So yeah it’s happening with steam boiler fully off and cooled down .
It’s not happening straight away, one video is after about 25 minutes and there is nothing wrong happening, group head was already red hot as the whole machine was.
Second video is after about one hour , already different , I can’t be the only one puzzled here 🤔
Edit: no crazy amount of steam either on one video.

Because they a German
