difference is.. Foto is when i turned the machine off.. And the video is when i manually start the rinse program.

I rebuilding the brewunit again and it didnt do anything. Just tried a Jura E8 and that container stay dry after cleaning. I am out of options, because everything is oke, drainage ventil, drainage motor works, brewunit goes up and down smooth and fast. Also if it finishes cleaning, it doest the last squeez and pushes last water out.

Cleaning process here. even when i start it, with empty container, i find wter in the container when its ready. I think tommorow i am going to dismantle the whole brewunit again.

it happens at the moment the brewgroup is returning to its start position, when its at hoghest point. Its comming from that mushroom thing :-D. I opend the brewunit.. but cannot find anything weird.

After a few cups its a puddle of coffee.. i dont have that with my other machine, its pretty dry

Hersteller: Jura | Typ-/Modell: S8 | ca. Baujahr: 2017 hi all, I am working on a jura S8. Rebuild the brewunit and cleaned inside and out. While making a cup of coffee the coffee pucks are nice and round. Also dry coffee pucks. But after the machine cleanes (while turning off) or after a few minutes not using.. the machine throws water in the coffee ground container.. what makes the coffeepucks watery. Its not the steppermotor, that one is working.. als the drainageventil is oke.. someone an ide…

Zitat von BlackSheep: „Thats new… In 25 years I saw never a brewgroup gear with missing teeth…(now correct - autocorrect…) But the effect is the same “

Zitat von BlackSheep: „Here is a little more detailed: An intact brew group drive motor is mechanically "stopped" at the end positions. The encoder detects that the motor is being controlled but is no longer moving – this generates the command to reverse direction. If this doesn't happen and the gears skip, it is either not mounted correctly, or (much more frequently) there is a break in the mounting lugs or a crack in the motorhousing. “ thanx blacksheep! You fixxed it again. In that large gear…

hi all, fixxed the pump issue with replacing the blown triac! Thanks all!. But now i have the same issue with the brewgroupmotor.. i keeps rotating.. from moment i start machine. Triacs are all good. Machine worked very good since i replaced the triac for the pump. I already Replaced the decoder, but it didnt do anything. Someone already had this same issue? Thanx!

that is the same one, but its a new pcb.. The triacs are smaller and soldered on lying on the board.

i found the blown triac.. but cannot find the exact same one online or in a shop. Can someone help? Where to buy? Thanx

Zitat von Tobias.L: „The Triac might be broken. You have to find out wich one it is. The one with heat sink is for the heater. Thanx!! I thought it would be someth9ng like that.. Keep you updated. “

today i replaced the pump. But the pump is working nonstop.. thats why the previous pump broke. People familiar with a pump that is constant running? Its probably a pcb issue, but where on the board? Thanx!!

Hersteller: Jura | Typ-/Modell: E8 (G2) | ca. Baujahr: 2022 hi all, I have a jura e8 2022.. with a problem. When i turn it on, it asks to remove the tray. After removing tray, it asks to rinse the watereservoir. And after that its asking to fill system.. But i never heard the pump.. i think its the pump that is dead, but i want to ask before changing if this is a known issue? I think that the pump died when doing descaling, and now its stuck in that mode. Or is is possible that its the pcb? Than…

thanx.. after turning on, it goes directly down... what i did, i turned the polarity of the brewunit motor and when it started, the brewunit went up.. and then got stuck with error 8. I shut off the machine and returned the motor kabels as it should be.. now it started from top position and went down and up again.. Something has been resetted? Because ow its working again. I have no ideaa how.. but i think machine was shut off with brewunit in top position.. and some how it kept it in memory. Th…

Hersteller: Jura | Typ-/Modell: C9 Impressa | ca. Baujahr: 2010 hi all, I have a jura c9 that is giving a error 8. I cleaned the brewunit and is running fine by hand. Also replaced the decoder, but everrytime i turn on the machine the brewunit goed down.. and it gets stuck there till i get error 8. It looks like the pcb is nog getting a signal to go up, but decoder is replaced and nothing happend. It looks like the fault is in the pcb, can someone point me in the right direction? Cannot find any…

Hersteller: Jura | Typ-/Modell: D4 | ca. Baujahr: 2015 hi all, I am trying to help someone from a distance. He has a Jura D4 and his machine is starting and cleans with no problems.. but he push the coffee button the machine starts grinding. After that nothing happening and the coffee en espresso lights are flashing. What is the meaning of this flasing? Error 8? Machine and brewunit are clean and moving. Thanx Mechanische Kenntnisse vorhanden: JA | Elektrische Kentnisse vorhanden: JA | Messgerät…

thnx! I measured all the diodes already.. but couldnt find defective ones. I am going to search for a display unit.

thnx, i opend the display module, and checked all the prints for water damage, but couldnt find any traced of water getting inside. Cleaned them all with alcohol. But nothing. I can hear the pcb in the back click.. it wants to do something.. but its stuck somewhere.
