Caffeo CI, extremely sour coffee

Hi,

I have been the owner of a Caffeo CI for about one week now.
I have about 50 covers on the machine at the moment, but unfortunately I haven't been able to drink more than 10 - 15 coffees because they all tasted extremely bad.

Before the CI I had a Nespresso lattisima, based on the comparison machine my perception of the coffee is related. For example, I find a Kazahr with 25 ml to be intense in taste, but neither bitter nor sour.

I have already tried several bean varieties at CI, e.g. Espresso Crema of the brand "JA! natürlich" (Sold in Österrecih at a REWE Group shop as organic fair trade coffee). But I have already ordered coffee like this: "GEPA Mexico Bio Cafe Chiapas Bean" from Amazon. Or also a coffee from a local espresso/juice bar (Buna).

However, no matter what I adjust, the coffee is always sour. If I set it to 40ml, hot, 4 beans (starch) and finest grind, the coffee is bitter with an acid aftertaste...

So I can get it bitter, but the acid never goes away...

After a little googling I looked at what makes the coffee sour, I tried to adjust the machine so that I get the sour off, but without any success.

One thing I noticed was that the coffee is sour everywhere when the brewing time is too short, unfortunately I can't adjust the CI. Now my question to the owners of the Caffeo CI`s:

How long does it take your machine to make an espresso?
When I press the espresso button I get 40ml from the machine (which is quite a lot from the quantity). The machine only needs 5 - 8 seconds for such a quantity of coffee, depending on the degree of grinding and temperature. The nominal value is 15 - 25 seconds for 25 ml. So my brewing time is extremely short, is that normal? Or is my device defective? Is the Üulver perhaps not properly compressed? The pomace also appears moist to me.

Edit: The 5 - 8 seconds refer purely to the brewing time, without grinding and without pre-brewing.

Do you have no right of exchange?
would they be cleaner and returned to the market.
As an alternative I would lower the brew temperature restaurant.
grind quantity less, somewhat coarser.
That the coffee pomace is moist, normal, design related.

Hi,

I tried a lower brewing temperature, in all grinds and in all combinations. My result e.g.: coarse with temperature low or normal - > not bitter but extremely sour.

The only setting that is drinkable at all is: 3 beans (starch), temperature medium, grind medium. This is also sour, but still so that you can swallow it.

I have on the machine 30 days money back guarantee from the dealer received. However, I am not sure if I should give it for repair because it is broken, or if I should exchange the device for another (other) manufacturer.

I do not know what is with it nevertheless say that you your exchange right were should and to you first with the specialist dealer the KVA´s demonstrate lets.

You cannot transfer the parameters for espresso preparation with a sieve carrier machine 1:1 to a fully automatic machine. But that it actually tastes "sour" with all settings cannot be. Is a filter cartridge inserted in the tank? If yes, test without...

In the water tank I have no filter cartridge because the water is filtered at the house supply line. This inlet filter was necessary because every household appliance was broken within a few years (2-3).

My kettle had a 3mm layer of lime on the inside after one week of use.
The water is extremely hard here.

Since I have a filter at the inlet, my water has 8° dH. But this should fit, right?

Any news? Did you find the solution?
