Wasserlauf – Brumming loudly and hardly no coffee…

Hi Nico,

Thanks for your quick answers.

I’ve never heard of Rudolph coming from Sweden but maybe it’s in a german story? In fact Rudolph isn’t one of the more famous characters around the swedish christmas-celebrations. I don’t think our kids know who he is. I’ve only of him through the song and that’s from the english version. So I don’t know.. ???

I haven’t decalcified my machine at all. (I’ve had it for 2-3 months. Bought it as used.)
From what I know it had been used with a Claris water-cleaner all the time. I changed that one 2 weeks ago.
I ran the cleaning-procedure also 2 weeks ago but that didn’t cause any problems.

I doubt (a little ;)) that the pump is defective because the machine is building up the preasure and forces me to open the cap to relise it. When I do so the amount of water that I wanted to be coffee comes out. Could the pump be defective then?
I would suspect that there is something that is blocking the path somewhere. Because there is a small amount of coffee coming through (approximately 5-10 ml of a 50 ml brewing).
Could this info give you any more ideas of what’s wrong? :-\

Hi Nico,

Guess what.. ::)
You wouldn’t need to go to Sweden. I’ve fixed the problem  :o   and right now we’re expecting a snowstorm…  :-\

I opened up the machine and there was a lot of pieces of beans right were the coffee separates in two directions into the cup. I cleaned it up and now the machine is working again  😀

With the snowstorm coming I would have time to lit a fire in the fireplace, enjoy a cappuccino and do some more fixing with my machine.
I would mount a PAC today and also try to change the famous brewrings. I’ve bought brewrings to have at home as I understand I would need them sooner or later. Of course I bought the parts from coffeemakers.de  😉 but you should see how the cleaningsticks looked like after the journey to Sweden. None of them was longer than an ordinary match. 🙁
But I’ve decided to change the brewrings anyhow today, to see if I get more taste into my coffee. Is this something I could expect?  ???
Right now I use the finest grinding and always brews cappucchino EXTRA to get a decent flavour/taste.
I’ve never de-calcified my machine. Do I need to do that even as it always uses the claris water-cleaners? From what I’ve read there is a big chance of needing the new brewrings after such a cleaning. And if I need a cleaning I for sure would like to do it before I change the brewrings. Please give me an advise.

I’ll try to get hold of a moose and check with him/her if they heard anything about rudi   ;D

Hi again,

Maybe it’s time to change the subject of this messaging as the problem changes ::)
I think your english is very good and maybe it would be me instead who should apologize for bad english. But please don’t ask me to write in german and I for sure wouldn’t expose you to swedish ;D I understand german pretty good to follow instructions and read the inlays. But sometimes there is some words that I don’t understand…

I cleaned the „bruhgruppe“ and changed the o-rings yesterday. I followed the very-good detailed instructions from coffeemakers.de. But there was a few places in the instruction where questions popped up, but I think I got it right at last ::)
But when I would test my E75 it sounded bad. I’ve got exactly the same problems as this thread is describing:
Link aus Datenschutzgründen entferntsmf&Itemid=134&expv=0&topic=54.0
I got the errormessage/Störung 8 :'(
I would suspect that the „bruhgruppe“ don’t move around correctly. But it did move around when I tested it manually before I put it on place…. But it was a little bit hard to move when the mechanik was going around in some corners. I noticed that the „untere kolben“ was not exactly into it’s opening. When I rocked the „untere Zylinder“ it would come around. Could I have mounted the „untere kolben“ wrongly? ??? From what I saw the kolb looked the same from both sides when I put it down it’s zylinder. When I look on it it’s top is above it’s cylinder-opening just a tiny tiny bit. I suspect that it is this that makes the mechanik slightly hard-moved… or…

Another thing that was a bit strange.. 😮 On page 27 of 30 in „Wartung der Bruhgruppe Teil 1:Demontage“ it saes that I should change both Kolbendichtungen and the „dichtungen im Drainageanschluss“. Kolbendichtungen is ok but on the picture there is 2 small dichtungen marked for changing (in a red circle, number 7) but I only got 1 with the Wartungsset Jura Brühgruppe BG3. ???

Hope Rudi has finished dancing ;D
I really appreciate all the help I’ve got from you. It’s much appreciated as I don’t think there is any Jura-service available in my area. :-*

Hope to hear from you again.

Regards from a calm snowy-white Sweden

Thanks again,

I would demount the brewingunit again later this afternoon and will check and double-check everything again.

Of course I’ve used the Siliconelubricant. It’s says so in the instructions 😉
But I only put in on the innerside of the cylinder containing the „unterer kolben“. But I guess that would grease the o-rings anyway or should I grease them individually?

I assume the brewingunit-engine is that found on the other side(right side) of the machine which are fastened with 2 screws… ::)

Is it possible to mount the machine with not putting the sides and the top on to be able to have a look of what’s happening? I’ll give it a try 8)
