Too Much water , use less water .

Too Much Water .....

Too much water .

Dont worry about what that bloke said.
I have just had the same problem - the machine thinks it has a filter in it so take it out and follow the manual to deactivate the filter. You will now be able to rin the descale.

Hello, make sure the magnet in the water tank moves freely, sometimes it gets stuck with deposits, its a small black rectangle near the base. if its not free, you need to put some descaling solution it the tank to clear it.

Have you run a decal recently? This normally happens when a small particle (normally) an undesolved piece of the decal tablet is stuck in the flow meter, or sensor.
You can try and run warm water through the system and after about half a tank it should be sorted out.

Run a decalcify cycle, your system sounds clogged

You need to open the grinder, it`s probably packed with old fine powdered coffee that blocks the outlet. Clean this out and try again. Since it works normal when you use pre-ground coffee, there shouldn`t be any problems with any other parts.

Let me know if you want a description for have to open and clean the grinder.

Good luck!

call the 'Coffee Boss"  in North carolina.  you will have to find him on Google. his name is heinz and he is the guy that Jura uses when they can't fix it.  He's fixed my x90 3 times.  
good luck

try and do a heavy duty de scale of the machine , put some descale directly into the tank, heat up ( de scale works better at high temp) select rinse, clean or flush programme. the vast majorty of probs. are due to limescale in the narrow pipe work.
