The machine just doesnt power up anymore.
No lights or nothing after plugged in and power on. Is there a fuse? Where should I begin in troubleshooting the board?
Use this great teardown as a way to get to the logic/control board. I do not have the J5, but other Jura manuals and they all show a fuse on the circuit board. Once you take yours apart, post an image of the board and I am sure we can assist you further. Hope this helps, good luck.
As oldturkey03 said I would suspect the fuse first. Mine too was not powering up and when it did it would not recognizing the tray being in place. I took it apart looked for any easy electronic problems: fuse, burnt areas indicating over heating or failed electrical components / short, loose electrical connections etc. Never found what the exact problem was but something may have been loose because after doing the above and putting it back together it worked:)
My J9 has a sneaky power on toggle near power cord entry to machine and can be accidentally turned off if moving machine or cleaning counter near machine.
I just bought a used Jura and it would not turn on. I found that the micro switch on the rear of the machine, which is operated by the small access door at the top, had become loose. Pushed it back in place everything worked fine
Having issues with my Jura S8. It wasn't powering up, so I fixed the switches and was able to get the power going but now the screen shows "Jura" and just keeps blinking. Does anyone know what the issues could be?
