Ena Micro 9 one touch Error 8

Hello,

my Ena Micro 9 has done now about half a year error-free your service (Espresso, Cappucino, Latte mac. regularly) and that very satisfactory. I myself used the caffeinated beans in the grinding compartment. My wife uses Illy coffee decaffeinated ground via the extra tray. Since a few days the machine needs some time longer for the grape marc ejection and it sounds as if the mechanics have to work harder than before. Once the display showed "Error 8" and then nothing happened anymore. My guess is the powdered coffee has settled in the mechanics. You can't get anywhere. According to the operating instructions, the specialist dealer must be consulted if this error occurs...does someone have similar experience and, if necessary, a solution?

Jura ENA Micro 9 One Touch

Error 8 does indeed indicate problems with the brewing unit, if it runs strained, you are absolutely right with your guess. In my opinion, coffee powder cannot get stuck in the mechanics, too fine powder would only clog the brewing sieve and prevent coffee from being dispensed, you would notice that directly. Since there is certainly still a manufacturer's guarantee, you should better not open the machine yourself, the brewing group is not so easy to reach...

Thank you for pointing that out. I bring the device tomorrow to the dealer (with own attached Jura workshop...) and will report...

I've had an ENA 9 since January 2012. So far I've had 2 times error 8 and the machine had to go to the workshop 2 times.

Hello espresso friend,
I bought the JURA Ena micro 9 one touch in November 2011. Had the same error even after a short time (ERROR 8). I sent the machine to service, this went quickly within a week of take out. Machine came back, infected, Loud Rattling. Then I packed them up again and sent them back to the service. She came back a week later. In summer the machine is now defective for the third time with the error (ERROR 8). Now we have a new/different ENA micro 9 touch for about 2 weeks now - This one is already defective again with error/ERROR 6! I also have to say that we are a 2 person household and we use the machine for between 1-4 coffees, which I think should still be within the scope of this machine! I am seriously disappointed by the quality of this machine. I think I will now return this machine to the dealer and pick another make from another company!

Hello,
mal a current state of affairs on the problem. At the end of 2011 we had bought 2 machines from the dealer. In the meantime, both were for repair, both with Error 8. According to the log printed out by the dealer, it says: "check encoder/cable b!" and "initialization/positioning not possible!" Both devices were repaired under warranty. As soon as one of them was back, the other machine issues the error "fill beans", although the tray is full...

If somebody has a hint how to solve the problem without running back to the workshop, gladly...

Lansam is getting rid of my enthusiasm for the device, I would have expected better from Jura...

My Ena9 micro did the same.
Mal error8 then mal error again 6
Also brewing unit disassembled overhauled ... no success
Drainage motor replaced .... no success
Encoder replaced ... no success
I disassembled the machine 3x and found the error by accident.
The holding clamp of the encoder was lame, causing the encoder to slide 1-2 mm up or down.
The clamp bent back and since then the machine has been running super again for days.

Hello,

though the contributions are already years ago but I would like to report from my last Odyssey also times. My ENA Micro 9 was last also with the appropriate Jura dealer to the repair because of Error 8. The whole then was the purest Odyssey. The first repair attempt was 4 weeks. Afterwards the machine was back home for a short time ...worked for 3 days and then went back to the dealer. It took another 8 weeks until I had the machine again. The machine showed error 8 at both Error 8.

Sometime I had the machine again ...it worked partially ....but the brewing group ran sluggishly and screeched. I then decided not to move the machine anymore and was already thinking about buying a new one...but now I wanted to know:

The brewing group didn't stir anymore and the gear motor rattles at the gear of the brewing group. The reason was: Due to the cumbersome brewing group, a bracket on the geared motor ruptured: So the geared motor including bracket was reordered and replaced.

The brewing group was still not running. So BG disassembled, cleaned and reassembled. It actually went relatively well. But it still appeared ERROR 8.
I then ordered a new revised brew group at a reasonable price. Built-in but it still came to ERROR 8.

I exchanged the encoder for a cheap replacement model and still ERROR 8 came. Then I checked the cables for continuity from the encoder to the control board. But that was okay, too.
Because I had noticed that the encoder moved minimally in the holding clamp, I bent the clamp and fixed the encoder with small cable ties crosswise. I also used Teflon tape to keep the encoder on the geared motor better in the guide. It sits now wobble-free.

Furthermore I checked the circuit board of the power sprint (where all cables sit on it) with all plugs for continuity and with the circuit board I noticed that the continuity check of the solder joints was not clean with all. Probably corroded or something. She had a few years on her back. So all solder joints of the plugs on the back of the board soldered and measured again - now everything was ok.

In another forum I read that someone claimed that the polarity of the gear motor does not matter. Unfortunately, I hadn't remembered how he was hooked up either. Another forum, on the other hand, said that the BG's initialization drive always goes up first. With me it was briefly down, then up, down again, then up, down again, down again and stopped ...so ERROR 8.
The solution: Replace the plug of the gear motor (plug left to right, plug right to left) and behold....now it's running again.

I had two test coffees with the message "bean container empty" although it was full.... but the machine grinded anyway. Now the message doesn't come anymore. I have already tapped 20 coffees again. She's running. If the message bean container empty comes again, I will disassemble the grinder again.

Now I hope that the machine will run well for another few years.

Great contribution. You are absolutely right about the geared motor. It is essential that a mark is made before removing the cable. Never mix up red and black. Dadorch changes the direction of rotation. With the grinder it is usually the case that with the first two cups either only a small amount of coffee is dispensed or the message "Fill beans" is displayed. This message also appears when the millstones are worn out or not properly adjusted.

I got the dreaded Error 8 on my ENA-8. I had heard that it was struggling through its cycles on power up and down. After reading everything I could find online (power down, tap sides, etc.) I tried repeated cleaning cycles. Like twice a day for a few days. Those little tablets are costly, but cheaper than dealing with a repairdude. Not only is the error clear but I can now hear that it cycles without effort. Clearly this wonʻt work for everyone, but may be worth a shot.
