Hi group, I am new to the forum. Many thanks in advance. I need to know how the drain valve on my Jura F9 works. As is, everything dumps to the tray. I have it apart but nothing is obvious. Theory of operation would be nice to know.
Thanks

ok

well, I just signed up to help you.

the drainage valve works like this:

when the selenoid pushes the white spring (when you hear that bump noise) it allows the water to escape from the bottom (there is a small hole , a rectangular one).

when the spring is not pushed by the selenoid, the water goes up from the central plastic pipe to the infuser.

now,you have to check if the white spring on the bottom is pushed by the selenoid , if so the selenoid is faulty and needs to be replaced.

Thanks,
I actually found instructions on how to take the machine apart and discovered all its secrets. The problem is that the plastic piece that the solenoid hits has separated from the valve stem. And refuses to stay connected. I have ordered new valve and will replace all the orings at the same time. Tomorrow I am going to superglue the valve together and see if that solves things for awhile. Thanks again for the answer.

Hi,

I'm having exactly the same problem, although on th f50.

I'd be really grateful to hear the conclusion to your story.

I was thinking that the solenoid clicks and ensures the water goes into the brewing head.  However my drain valve doesn't seal properly either way (tested by blowing through and manually poking the valve)

Also interested in the instructions you found and also where you got the new valve from.

Any help most appreciated..

Thanks,

Paul

And now" for the rest of the story".
I did superglue the drain valve back together and it worked fine for about four months. Then it separated again and I replaced it with a new valve. Still working fine.

The first couple of times taking the machine apart was interesting--kept expecting to hear things break. It actually is not too difficult.

Keep us informed of progress.
