Jura Ena 5 defective

I have a faulty Jura Ena 5. Display shows "ready". If you want to brew a coffee, the coffee is ground, the pump starts, pumps a little water and then sounds as if something is blocking. The machine then stops the brewing process. The pumped water lands together with the wet coffee grounds in the collection container.
We have cleaned the machine several times (cleaning program and manually, brewing group etc.). We laymen then decided that it could only be a defective brewing group (seals). But I could have saved myself the purchase of the revised ones, the error still exists...
Has anyone got an idea?
Thanks for your help

Does the message "Fill beans" appear? Does the rinsing function smoothly?

Thanks for the quick reply
The message "fill beans" does not appear. After repeated cleaning and decalcification the rinsing works without problems.

Flushing and cleaning works, so the coffee path is obviously not blocked.
"filling beans" does not appear, so the brewing process is not stopped due to lack of ground material.
You have already replaced the brewing unit.

Hmm, there is not much left, maybe the pump is weakening or the diaphragm regulator has a problem...

"tap open" does not appear either in the display?

"Cock on" the machine demands a break - that's right.
We still have a second pump lying around - so we could just "test". Had ruled that out until now, since pumping is the way it is. Hot water is great to prepare.

If the request for venting appears, it is quite certain that the ground material is too fine, then the brewing sieve will clog/glue. Forget about the defective pump, check the grinding degree and wipe the brewing sieve clean with a damp Zewa...

Unfortunately, still the same mistake. We've checked the grinding degree, the sieve is also clean. While we were at it, the new pump was also installed. Still:
Switching on the machine
Heating up
Ready
A cup to be brewed
Coffee to be ground
Pump running
Powder lands in the brewing group
Short noise as if the water wants to be "pressed" to the coffee,
there is some blockage - the brewing process stops, the wet ground material falls into the collecting container.
Then "Open tap" and "Close tap".
No coffee

Hello,

>sounds somehow like a drain valve.... this often dies

But then rinsing and cleaning would work just as little as the coffee supply. Either the coffee way is free or not. Since the water reaches the brewing chamber, the AV actually falls out as a suspect...

Hello together,
Yesterday we tried to avoid the grinding process and brew coffee with ground coffee. Unfortunately also without success.
It seems almost as if the coffee powder (whether before ground or not) falls almost dry into the collecting container and only becomes moist afterwards by some leakage (does not look like a pellet). Water slightly coloured by coffee also ends up in the bowl under the powder collecting bowl.
The pressure built up during the interrupted brewing process is then reduced by the hot-air nozzle. That until the water tank is empty.
...but a flaw in the electronics?

With our J5 the same thing has happened since today, only here is bean filling in the display and with powder filling it works.
I removed all beans and cleaned the grinder after unscrewing the plastic rust.
What else can I do? Unscrew grinder? Is there a fuse for the grinder?

If the grinder does not start at all, in most cases the motor is simply defective, in rare cases it can also be due to the power electronics. There's no fuse.

is confusing...actually all the water comes through the coffee spout nozzles while "rinsing"...all the water is not washed...all the water is washed away...all the water is washed away...all the water is washed away...all the water is washed away...all the water is washed away.??

When water is pushed downwards, it is actually the drainage valve, or else, the brewing group was incorrectly assembled (lower brewing piston incorrectly inserted)

otherwise there is not much left. I exclude electronics.

I would disconnect the water hose from the heater to the brewing group once at the brewing group and hold it in a cup. Then trigger the coffee brew. If the cup is made nicely full of water, the sturgeon is found. That leaves only the brew group. If no water comes out of the hose, keep searching backwards.

This must be possible to solve.

because I am now in the same situation, I would like to know how it turned out?
My Ena 5 is on strike since today. Everything exactly like questioner.
End with "tap open, water out and tap close "
Many greetings and thank you in advance.
