Jura C5

Quick Mill 05000 "Unique Edition", WMF Ecco

My grinder was equipped with "carbon brushes".

The grinder has a white bottom and the bottom and the brush hatchers are fitted with small steel clamps.

With a bit of effort you can bend them back and get them out.

After removing the grinder it turned out that one of the two coals must have gotten bent somehow.
Because this coal was very slanted and almost used up. In addition, it showed strong marks of flying sparks.

The exchange of the coals was not sooo difficult at all. Fiddly was getting out the carbon holder plate (This plastic thing at the bottom of the engine)
This cover was secured with known "noses" of the engine housing and these could be bent back badly.

New coals I have sanded myself out of slightly bigger coals.

For those who are interested: Carbon thickness 3mm, width 6, length 8mm

After everything was now reassembled and cleaned read the first problem run to see that again everything runs as it should be.

Whether it is a Johnson or Domel engine I can not say because only some numbers but no company name were printed.

Motor housing was zinc-coloured, plastic carbon holder cover white, and the carbon was pressed onto the collector in a rectangular holder by means of a pressure spring.
(Perhaps someone can draw conclusions about the motor type from the data)

Hello,
had the same problem as described by charly93:
Machine does not brew coffee, only a few drops come and water has to be drained through the hot water/ cappuccino nozzle.

Problem in my case:
My Jura is operated with a filter cartridge, machine draws air, which must be drained through the nozzle.

Solution:
Filter out -> everything is fine, coffee runs!!!
Had additionally run the decalcification and cleaning program several times and cleaned the brewing sieve. Can't hurt!

Call to Jura-Service-Hotline confirmed this! Probably happens more often that the filter cartridges are defective!

Bin curious whether this will happen again with another cartridge. For the time being my Jura runs without a filter cartridge, but I changed it so that it is requested to decalcify. Probably it is better to let the decalcification run from time to time anyway despite the filter cartridge....

Descaling should nevertheless be carried out because the cartridges only filter out part of the lime.
depending on hardness....

I no longer use the cartridges. On the one hand too expensive and with my degree of hardness 4 I must decalcify anyway additionally.

I decalcify with Durgol 1:3 if requested and have no problems.

Durgol is available on ebay in the 10L canister quite favorably.

With it I decalcify also all other...

Good morning
love thanks for your clues. My husband is just about to disassemble the coffee machine again to follow your tips. Among other things I followed the tip with the new grinder and ordered a new one from Komtrade (with a new Domel engine). Now he's there, but looks like he's been used before. After reading it again it was in brackets revised . After google, it's a general overhaul. So already a used ???
Please inform me this side .
Thank you charly93
