Z5 dumps everything out the thermo-couple drain
Posted by: DaveSpider January 02, 2023 03:52 am
I have a Z5 and am having the issues where no matter selection I make, everything gets outputted thru the thermo-couple into the drain pan. The ceramic valve sounds like it's working correctly and no error codes are given.
I'm still guessing the CV is not functioning correctly - although when I dismantle it, I see no signs of calcification, etc.
Any suggestions?
Thanks!
Dave.

What is a thermocouple and what is CV?

Hello,
I had the same thing with a Jura Z6.
It turned out to be the driver disc in the ceramic valve.
The cams were worn and the ceramic valve stayed in a position where everything goes into the drip tray, and coffee goes dry in the coffee grounds container.
I would have no error message and all the water and steam came out in the drip tray back outlet, so not the drain valve.
Sorry for the Google German.
