Jura capresso e9 water not coming through spout

I have 3 different coffee machines and all 3 are descaling like you said using only the froter so that is normal .... Unless you misstyped the question

If it's clean water which runs out, check the hoses going from the water tank to the pump then through the boiler to the brew group. If coffee is running out instead, then it's the spout going from the brew group to the cup. I know Saeco's not Juras but they all function the same way.

You need a new drainage valve on the base of the brew unit.

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

You can find the Jura manuals here:

As the coffee is dispensed, it is normal to have some residue left in the tubing and spouts. It is the reason that the machine will require cleaning on a regular basis using the Jura tablets that dissolves the coffee film. In the case the spouts get clogged, the best approach would be to dismantle the spout assembly. Since it may not always be possible, I found that filling a cup with a coffee cleaning solution such as Puly Cleaner (pulycleaner.co.uk) and having the spout dip in the solution overnight can help. Probably that dissolving a Jura cleaning tablet in a cup of warm water would provide similar cleaning power.
Dismantling the spout is rather straightforward. You start with removing the front logo by rotating it counter-clockwise. Behind it you will find a T15 Torx screw. Removing it will allow removal of spout cover by pulling the top part lightly towards you and then sliding it down below the spouts. Grab the spouts by the sides and wiggle downwards until it comes loose. You can now clean the spouts but will most likely need to soak it. See the video showing removal of the spouts @ youtu.be/9QlRGY0eX3s

This is most likely due to a bad o'ring. The bar you speak of...Does the unit have a small spout pointing upward from the area?...with a groove? Is the o'ring in that groove damaged or missing? When the grounds are compressed in the piston, the brew unit lowers down onto this spout and seals on it. The high pressure water then is injected upward inot the brew unit. When this seal fails the water simply leaks into the tray when there are grounds providing backpressure. When rinsing and no backpressure some of the water may be getting through. Make sure you lube up any seals with a food grade lube. Olive oil will work in a pinch.

Your spout is probly cracked (a common problem). It won't hurt the machine if you want to live with making one cup at a time to catch it all.
If you want to get it repaired go to www.hotncold.com Click on Jura Repair for shipping instructions. We can turn the job around in 24 hours. The repair will also include a free software update.

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.
