Water will only dispense out of the frother.

It could be several soutions to this problem. First of all, try to clean the sieve in the brew unit, it may be clogged. Take out the tray, in between the 2 brown "lips" inside you can put your finger up and clean out all the old coffeegrounds stuck up there. Then put everything back in place and run a Rinse machine operation.

If this is not helping, listen out when you start up the machine; You should hear that the valve is turning 3 times, if it doesn`t it can be a problem with this valve not opening in right position. Then all the water would go out in the tray, and not into the brew unit. That maybe can be solved by changing this Multi ceramic valve or the Main Electronic board. Then it`s a job for a sertified Jura technician.

I have had the same problem, and thought it would be something expensive like a solenoid valve.. Turns out it cost nothing to repair, but you will need to dismantle the machine a bit.
There is a plastic pipe behind the front panel, which pivots like a see-saw, and this is what diverts the flow... it is just stuck, and needs cleaning.
If you are capable to do the job, it will cost nothing. otherwise, leave it to someone who knows what they are doing.
