Have a Jura Capresso E8. Water is being dumped to the tray and dry grounds are being sent to the grounds bin. I do not believe it is a clogged nozzle, as the grounds are perfectly dry. Any suggestions?

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

For Jura F7 Series, "Tray Missing, can't put it back in". With a small flashlight, look in to the cavity which the tray and grounds container reside in. Along the right side above a slot to the end, you'll see a white micro switch. with a "Tooth Pick" simply press the switch inward (to the right) and hold till the machine cycles the Levcer / Flap up and out of the way.! Put your tray and grounds container back in and begin brewing!! -dh

I had the same issue. Had to send mine in for repair. Cost $235.00. Nothing I did would fix the issue. They said there was a major blockage. They cleaned it and sent it back. They also fixed my issue with water leaking from the frother.

Hi, I made a video how to fix your Jura step by step, good luck... http://fixandparts.wix.com/nicknicoloudis#!jura-coffee-machine/c15gy

I have the same machine and this seems to happen if the grounds bin is pulled out before it goes through a full cycle. take both the grounds and water trays out. Try to fit the grounds bin around the "elevator", slide the grounds tray underneath that then the water tray as well. It should slide right in then the machine will complete the cycle and work just fine :)

One of the problems that I see with these units is the Grinder setting. Sometimes the grinder is set too fine for Dark and Oily beans. This setting will ( can) clog up the brew screen after less than 10 cups are brewed. Also, running the cleaning tablets through to create a clean starting point may help you. Try turning the grinder to a slightly coarser setting and try that.

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.

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.
