Hersteller: Jura | Typ-/Modell: Giga X8c Professional | ca. Baujahr: 2017

Purchased this machine couple weeks ago and it was properly emptied for shipping as described in the manual to avoid freezing.
Had to replace all hoses with proper silicone hoses since someone used vinyl instead and they were all stiff and kinking.
Now the machine is stuck on filling system over and over, can't even access the menu.
The machine is taking water, all water ends in the dump drawer, none goes to the front spouts.
Also noticed that only one pump out of 3 is running (the one close to the ceramic valve)
Little blue 28W steam pump, and the back bottom Sysko pump both are silent.

Any ideas?
Should all pumps prime when the filling cycle is active?
I did try to prefill the other intake circuit that feeds those 2 pumps, no change.
Checked both intake flowmeters, and they look clean without any contact oxidation.

Thanks

Thank you!
I did mark everything as it was when I got it but it doesn't mean that the previous owner had it right after his "handy" work.
Inlets and outlets 100% correct but will have to chase the wiring.
Yes the flowmeters are/were clean like new.

EDIT:
Looks like the flowmeter connectors are swapped indeed!
Will test it later

That did it BS! Flowmeter connections were indeed swapped.
THANKS!

Now, new problem ERROR 15
The ventilation flap motor is making horrible sound but not moving the lever whatsoever.
I'm positive this was working before I opened it up, so my fault, but not sure what happened.
I did not remove the motor just vacuumed around it.
Do you see anything obviously wrong?
Yes, I did try with the top part fitted, no change. The motor is just not moving the lever.
When I took it out of the assembly, it also just hums but won't move.
Is it possible that it needs to be in sync with the micro switch?
Picture shows the motor in position when machine was switched off.
Does the shaft actually rotate when it extends out and when retracting?

Thanks

EDIT:
Looks like I managed to synchronize it.
The position you see above is flap open so when it boots you need to hold the flap microswitch
When you turn it off, the second you see the motor retract release it.
Now in sync again and ready to reinstall the lid.

Here you see the motor retracted and that = flap closed

While you put the top machine cover back on, the
I did see that about the vents in another thread but it did not work for me since I played with the machine no lid attached and it jumped out of sync.
When the machine was OFF the step motor was extended and it refused to retract on power on until I fake the switch status manually.
Looks like all working now, just have question about external water source and the tank. There was some talk about it in another thread so I'll continue there.

Thanks for your help BS!

One more question BS
The chrome flap around the power P and rotary dial can be lifted, why?
There is a pinhole on the back side and rubber cap on the front, what is this for?

Thanks

Interesting
Thanks!
