Hi all,
New to this forums and new to a bean and cup machine.

I got given a Jura s9 avantgarde from a friend with a Error 4 problem, I have since changed the steam temperature sensor which fixed the fault :)
While I had the machine apart I noticed it was FILTHY inside and also had a few minor leaks. I disassembled and cleaned the brew group and fixes all the leaks.

I replaced a load of the o-rings, the diaphragm regulator and outlet valve.

Having put the machine back together whenever I try to make a coffee shortly after it starts brewing the drainage valve kicks in and I get no coffee :-(
Anyone with any experience of fixing this machine I would much appreciate a point in the right direction.

Points to note -

The machine complains it needs de-scaling, I have not does this yet and would not have though that this is the problem.
From testing the machine will run a rinse cycle and produces hot water, steam no problem.

finally I have not run any coffee in the machine, could it be it is cleaver enough to know this and that is why it stops and turns on the drain valve ?

I can make some video's and post them if anyone thinks they can help ?

Thanks.

Droo.
