E 40 Brewing group and grinding degree

For my workshop I got hold of a Jura E40, but I have the following problems. The coffee from the machine is very thin and has no cream, and there is water in the tresta cup. Thereupon I changed the grindstones, seals on the brewing group and the drainage valve. Unfortunately this was not successful, still very thin coffee and water in the Tresta cup. So I ordered a complete brewing group and grinder from BND Kaffeestudio, unfortunately without improvement.
In the office I have an E75 and the motorhome an E70, there I did the work, both do what they should. Only the E40 I do not get a grip on, what could I still try.

What do you mean, no improvement?
Still water in the pomace bowl? Coffee still thin?

Yes there is still water in the tresta cup, and the coffee is still very thin and without cream.
What I noticed is that the coffee from the grinder is very fine, as fine as the filter coffee from the self-service market.

If you leave out the pomace bowl and press the switch in the lower right corner you can see where the water
comes
from

Temperature is ok? If it is too cold the coffee doesn't

really

taste

good.


For the crema the crema valve is responsible. But since you have installed a new brewing unit it should be ok.

Thanks for the hint.

Currently I don't have the possibility to measure the temperature of the coffee, but I feel that the cap is a bit cooler than the other machines. I can drink the coffee immediately black, I can't do that with the E70/75 and C5.

When I press the switch at the bottom right I only see that the water after the broths with the marc falls down and drips a little bit. So I will open the case after a while to see where the water drips.

Now I have lifted the lid, above the brewing group everything is dry up to the bottom of the flask everything is dry.

I have just unscrewed the lid at the top of the coffee spout and the piston is dry. The water must come out of the brewing group somehow.

What surprises me is that the coffee machine has this problem from the beginning, ok the brewing group and the drenage valve I had revised myself. It could have been good that I put the same error back in, but the exchange for the new brewing group and still the same error. So 3 times the same problem where I can not see through.

The problem is solved - the E40 now produces good coffee.

It was the setting of the grinder, I had set everything to mark.
After I adjusted the grinder a little bit more coarse it got better, after that some fine tuning and it was good. I would never have thought that the pomace is so wet that it drips from the brewing group because of the wrongly adjusted grinder.
I just assumed that if I buy a grinder that it is already adjusted.

Thank you for this note with the attitude. How does the coffee in the bowl look? Does it look like a pressed tab (that would be the normal state
)? I would have expected the grind to be even finer so that the coffee is no longer thin
