Jura F60 Impressa - Machine brewing unit will get stuck after cleaning cycle only.

    • Jura F60 Impressa - Machine brewing unit will get stuck after cleaning cycle only.

      Hersteller: Jura | Typ-/Modell: F60 Impressa | ca. Baujahr: 2007

      I just got my hands on on F60 machine that works absolutely perfect until the cleaning cycle is used.
      Every time the machine cleans fine but at the end of it the brewing unit will not return to the "home" position as it should.
      It will not reset no matter what I do.
      To get it out of this state I have to take it a part and manually reset it.
      Very strange since otherwise the machine works perfect.
      Don't tell me not to use the cleaning tablet :D

      Any ideas what's faulty?
      Thanks

    • Hello,

      this sounds like a program error in the process control.
      Should mean that a new/used control board is needed.

      Thanks for the prompt reply BS!
      That is unfortunate, does this happen often on these?
      Is there any way to get rid of the cleaning prompt without actually doing the cleaning?
      Perhaps some option to do factory reset on the machine?

      Thanks

    • Hello,

      malfunctions in the program sequence are very rare with Jura machines. However, I can't think of any logical mechanical fault that could explain your problem – therefore, I don't currently see any other possible cause.

      There is also no other way to reset the cleaning bit than to perform the cleaning cycle and complete it properly. Otherwise (as you probably already know), there's no real reset function on any Jura machine. This also applies to the F60, which doesn't exist/never existed under that name on the German market. According to a Google search, it appears to be a Jura xF50.

      The only other way to reset the cleaning bit is to access the machine's EEPROM and find and change the relevant setting within its contents. How? - I have no idea about electronics, control systems, and their programs ;) .

      I'm only familiar with program errors in Jura/Eugster machines specifically from the Krups FNF 2.43 and the Jura E10/25. With the E10/25, the two-cup brewing cycle is usually affected, meaning no water is dispensed after grinding.

      In these cases, it might be possible to salvage the control unit if you have a copy of a working EEPROM and install it. While this will result in the loss of brew counts, etc., with a bit of luck, the machine will then function perfectly again.

      Take a look at this article:
      Jura EEPROM Avantgarde dauerhaft Reinigen oder Entkalken

      It is good to use this machine as long as possible. Because no message to descale will appear. It is also not possible to descale manually, because the message to clean is not reset.

      The Jura F60 is a XF50 Classic for me, in Germany. I might have saved a working EEPROM with a normal Grinder, there were also Aroma+ Grinder built in. I had one F50 Classic there it was not possible to save the amount of water. If you switched the machine off and on you had the old, saved amount of water. It does not happen so often to newer machines that the EEPROM get broken.

      Thanks BS!
      What I find strange is that the machine will somehow get out of sync with what is the brewing unit doing.
      Yet if I just unscrew those two bolts holding the driving motor, move the brewing unit by hand to the home position,
      connect the driving motor back and power it back on, it will do it's initial cycle and will be back working and ready to go like nothing happened.

      Thanks Tobi for taking the time to reply!
      Since I use the google translator to read these forums I would have never find your post that you linked!
      Thanks!

    • Regarding the point about initializing the brewing unit, which is mentioned in the linked post by Tobias.L - see here:

      The Jura brewing unit is not in its exact starting position after installation - the brewing chamber is not centered under the powder funnel.
      Hm, that makes sense but wouldn't the machine recalibrate on the next power on cycle? In my case the brewing group is operating absolutely no friction or restrictions.
      I even tried to press the rinse button when the machine is in the wrong position, it will actually rinse, but at the end of the cycle it will park it self in the wrong position.
      Also tried at the end of the rinse to pull the drawer just before the cycle ends and the brewing unit position is in correct position , unplugging the machine, but when I plug it back and power it on it will move and stop again in the wrong position.
      Strange.

    • Hi, this has absolutely nothing to do with your machine or its behavior. This was purely an addition to the link from Tobias.L about the EEPROM, since it also mentions this.

      And no, it won't move the brewing unit to its home position the next time you switch it on, unless it "knows" from before that it's incorrectly positioned. That's precisely the difference. Previously, it did this automatically every time it was switched on; with ZES, it only happens when there's a "maintenance flag"—or when the electronics detect that the brewing unit is incorrectly positioned.

      Your machine doesn't recognize that it's in the wrong position - and that should be a problem in the control system.

      Oh, OK I get it now!
      I thought the machine uses predetermined parameters how to move the brewing unit to the home position, since it always cycles and moves the brewing unit on start up. Strange that when you rebuild the brewing unit that you don't have to insert it in it's home position and it will find the right spot anyway. (That's what I understand, never actually tried it, I always set it to home position before inserting it in)

    • Hello, the brewing unit initialization process works as follows:

      The brewing unit is in "some position" within the machine.
      To start the initialization, the drive moves upwards, and simultaneously, the encoder signal is evaluated.
      If, despite the application of voltage, the encoder no longer sends a signal, the machine knows that the brewing unit is at its highest position.
      The voltage is then reversed, and the drive moves all the way down. During this time, the encoder signals are counted and compared to a pre-programmed value.
      If the encoder no longer sends a signal despite the application of voltage, and the distance traveled matches the stored value, the machine knows that "everything is OK."
      It then moves a predefined distance (encoder signals) back upwards – so that the brewing cylinder is correctly positioned under the grinder.

      Otherwise, it will make one or two more attempts to return to the position and then (in almost all Jura models) goes to error 8 if that fails.

      From the moment of successful initialization, the machine continuously counts the encoder signals and compares them to target values. This also determines, among other things, whether and how much coffee grounds are in the brewing cylinder.

      Reinitialization can be triggered by a significant deviation in the distance traveled by the brewing unit, detected by a wrong amount of encodersignals or voltage loss during a movement process.
      It is also triggered (in newer machines with energy-saving circuitry) by a maintenance flag set in Jura's animation software, and in older machines by unplugging and replugging the machine into the mains power outlet.

      If a new machine with an energy-saving circuit performs a brewing unit initialization every time it is switched on, the maintenance flag in the control unit is set.
      This only occurs if Jura customer service did not perform a successful final diagnosis at the end of the repair. If this is successful, the maintenance flag is automatically reset. The flag is set automatically when the machine is connected to the animation software and the initial diagnosis is performed.
