The passage of water is not passing through coffee grounds. The coffee powder is dumped dry & water is bypassing the brew group and draining into the tray.
Causes:
1- Machine was not descaled. or descaled with automatic method only, as suggested by Jura.
2- There is accumulation of Calcium in the hydraulic system, generating back pressure. This reduces the pump pressure and water cannot force its way through coffee grounds.
3- Stop using filter cartridges. Turn the reminders off.
Solution:
Descale machine manually every three months. See link. Services Unlimited Inc Parts Guru Since 1988

How to Descale Jura Espresso machines
SOURCE: Water in the drip tray of coffee machine
take out the mecanism and clean it how is instructed in manual, than get it back carefuly. Pay attention on position of mecanizm.
SOURCE: 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.
