Did it work before this?
Sometimes hard water can build up and cause blockages.
Try mixing hot water and white vinegar (50/50 mix) and try running it through the machine. If this works, run it through a few more times than run cold water through a couple times to get rid of the vinegar.
Good Luck.

Open the drawer and take out the box for the grounds. Run a rinse cycle and it should now go back into place.

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!

I had a similar problem, and solved it by turning the grinder by hand against resistance. Apparently the grinder wasn't really turning during the cycle and needed to be cleared. If your beans are "hopping" this may be a different problem.

Testimonial: "Grinder is turning but old bean oil is clogging it. Stirring beans on next brewing after drying the grinder was also customer services recommendation"

There are two possible causes. One is easy the other is hard. So try the easy one first. Remove the grinds tray completely, and place you hand in the cavity that it normally takes up. moving you hand slowly in, feel towards the top. you will find a little flap, past that flap there is the tamper and coffee filter at a slight angle. This may be blocked, so clean with a cloth.
If that does not solve the problem (and 90% of the time it does) then you may have a small spec of dust that is stuck in the water system, this needs to be flushed and cleaned. The best place to do that is with a Jura approved center. Unless you are technically minded. Your local Jura chaps sound like they need a k!$k up their behind
