The drain valve needs to be rebuilt. I had the same problem with my Jura. I disassembled it and rebuilt the drain value and brew group. It is back up and running after replacing the o-rings and regreasing the parts. There’s plenty of videos on YouTube that shows you how to rebuild it. You can buy o’ring rebuild kits on eBay.

Where is the drain valve?
It's attached to the bottom of the brew group.

Hi there,
It sounds like the water lines are blocked with calcium. Have you descaled the machine?

Your drain valve is failing, allowing coffee to drain to the pan. It's a common problem. Either the seals are bad, or the steel plunger rod's plastic cap has unseated. Buy a rebuild kit for the drain valve, and consider gluing the cap on.

It might be the heat exchanger clogged with calcium. Locate the part and take it off. Unscrew the part and soak in descaler not clean. Reinstall.

Coffee dispenser works one time. Next time just dry grounds and no coffee at all.
The pump works? I would then follow these instructions for replacing the seals in the brewing unit and drainage valve (in the bottom of the brewing unit)
