ECM Puristika Issue
Starred Can the latter be speed up in one way or another?
you can put a towel over the group, probably shave 5 minutes or so off the time.
The only other way would be to overheat the brew boiler (by 10-15C) for the first 12 minutes and then drop the temperature to the correct one required for brewing…this would probably reduce heating time to 17 -18 minutes. This would require the firmware to be modified, of course.

And this is exactly what Lelit does. 😊
Flushing doesn’t help?

It might make a marginal difference…A tea towel over the group is much more effective.
Well, a quick update after 2 weeks. I have just been using the machine daily and over the last 48hrs the group head is now heating up on its own without engaging the pump. Previously it would fail 9/10 times so pretty happy that this issue has gone for now at least. Still interested to see what ECM’s fix will be.

Here a video I found on Youtube with a similar problem:

Starred He should have just reached over and grabbed a handful of group, much more dramatic….🤣
My dealer says that there are some models of other brands with the same issue and as these models never received a formal fix, it is likely that the Puristika will not get a fix either….
Cool.
I am willing to wait for a while.
But how will I know that they have fixed it?

I would imagine the retailer will send you a small part, or ask you to send it in?
Again had some email exchanges with my retailer. He said he enquired (I don’t know where) about this issue, and the response was:
“This is not a defect. This occurs in every E61 machine with Eco modus and ‘flow through’ (I don’t know if this is the correct translation?) boilers. You can speed up the heating process by flushing”
No clue what the value of this response is anymore to be honest

Very low, written by a retailer who doesn’t really understand machine design.

Any update on this issue? Thanks.
Beverast Thanks. I’m a buyer for this machine and not worried about them resolving the issue. I briefly owned a Profitec Pro 600 and it’s quality stuff. I see they are now offered via pre-order at Clive Coffee and Whole Latte Love in the US. Curious to know what the fix ends up being and would obviously prefer it arrive already squared away.

Beverast Yeah I am confident there will be a fix at some point. I have just emailed the Technical manager at Bella Barista as it’s nearly been a month since he last emailed me.
Re: the occasional thermosyphon stall on cold startup in the mornings.
This morning I got an e-mail from Michael the owner of ECM. They implemented my fix, and tested it, proving it works (as it should because a few manufacturers use my solution for vertical boilers, including ACS). I can’t really say any more because it’s up to ECM to announce it and roll it out to Retailers.
I would imagine it’s taken a while because they will have needed to test the fix…which as you can imagine, takes a while especially as the issue doesn’t happen every time

@DavecUK - What I find interesting in this particular occasion is that ECM had more than 2 years to test the Puristika since it was first announced as a prototype back in 2019, and yet got it wrong. So will they now test for a few months and think all is well? What I’m questioning here is, how come they haven’t picked this up during the testing process?
What’s also very interesting is that James Hoffman reported thermosyphon stall on the Profitec 500 (That’s an HX machine, horizontal boiler) last year.
I had a Profitec 700 (dual boiler, vertical boilers) for two years, back in 2015, and it never, ever had a thermosyphon stall. Every day religiously it was ready for me first thing in the morning as I rolled out of bed.
Given ECM is all about precision, quality and “German” engineering… This truly baffles me. Feels to me ECM is not what it used to be.
N.B.: Profitec and ECM are sister companies.
