Jura J5 Interesting problem with no water and no Fault!

Hi All. I have purchased a Jura J5, with a fault. Well technically it dosnt show a fault.

Original owner said was running fine then one day was leaking water from the bottom. and no water/coffee brew was coming out of the nozzles. The original purchaser (a company) gave it to an employee and bought a new one.

The employee tore it down and changed a piece of tubeing (i dont know which one) and now now it dosnt work.

You turn it on and it does its normal thing. It starts up and when it says ready, it grins beans drops it in the brew group, compresses it and dumps it in the waste tray almost dry and no water from the nozzels at all. Capp Spout is working fine with water etc. The nozzels you can hear it burbling, but nothing comes out. The machine is now leaking hot clean water all over the bench.

You can hear, that the machine is doing exactly and sounding exactly as it should. the pump is going the grinder is going etc.

so its on my bench torn down from your instructions on this site which are blinking brilliant! thankyou thankyou thankyou.

Before (and still now if i put it back together) there is no fault code.

There is no obvious blockage. There is no damaged pipes that i can see, no water leaking now anywhere.

Right so the interesting thing is: when i dissassembled the machine I found two things.

Step one two and three show a white formed plastic part with a hose attached. I dont have that. neither the hose or the white plastic part or the nozzle that attaches the hose to the brew group. I just have a arm that goes over the big hole in the top of the brew group. There is a spot that a hose joiner can go, but there is not one there. (if i can upload a photo i will¬!)

Link to tear down

also on step ten show a hose from the drainage valve. I do not have one. (as a question, if the drainage valve was taken apart (which i dont think the brew group was taken out before as its screws look perfect and untouched not like the other side of the machine where you can see they have been undone). but if the drainage valve was taken apart and somehow put backwards would that stop the flow of water?)

If I had a hose diagram i would be able to check where it is routed wrongly!

At present i can trace the water tubing from one item in the machine to the other, and all looks same in the images on the teardown that i can see. I can only assume it is from the very point that the water has to go into the brew group?? I can see a position where the drainage valve at the bottom of the brew group lodges into a socket that goes to the other side of the machine. I (think) that is where the water comes from?

Ok. Well Heres hoping all will be well, i dont have enough experience with how the machine is working to know where to look next. any ideas and also advise would be greatly appreaciated!

thanks again.

when there is NO Drainagevalve the water can not go through the brewgroup.

The hose which goes into the Drainagevalve is also the one who brings the fresh, clear hot water from the valve near the heatingelement. When teh Drainagevalve is closed, the water goes through the brewgroup and makes the coffee. For a dry waste, the drainagevalve opens after the brewing and lets the water flow out and air in, so the wate gets out easy and isnt very wet. the drainagevalve is switched by an electric magnet, it mmakes a loud click noise.

in this link: the hose brings fresh hot clean water,

in picture ONE the part in the white circle lets the water into the brewgroup dock.

The side where you can see the spring is the middlewall, behind that wall is the elctric magnet. sorry for my bad english, was not best at school. XD

Why would the drip pan fill with excess water? Seems like after about 5 drinks the drip pan needs to be emptied. Is this normal?
