Krups EA8908 Evidence: Improving Coffee Strength, Grinder Settings & Comparing to EA8298

Hello
I have a Krups Evidence 8908 espresso machine.
When I select ‘long caffe’ and the ‘dark’ mode is activated – with a coffee volume of 130 ml – the coffee comes out normal; it isn’t too strong.
I’m currently using Pellini Espresso Bar coffee.
Grinding time is approx. 8 seconds, with the grinder set to 1.
Is there any way to make the coffee stronger?
Is there any way to increase the grinding time? – via the service menu?
Thank you for your help


I’m comparing this to the Krups EA8298, where, despite a larger coffee volume of 160 ml, the coffee comes out stronger.

Hallo.8s correctly may already be used stones in the grinder and that's why they had a little coffee.

Hello

Express is only 2 months old and 90 coffees behind it so the grinder is rather ok

I have already had such a case that bad material was used to produce gravel stones.

So the grinder to be replaced ??, and what does the service menu look like ??, maybe something wrong was set up there?

Hello
Please check the service manual. If it is under warranty, please take it to the service center.

Hello

Thank you, I think I will give it to the service for help if it doesn't increase the grinding length to 10 s, the book does not provide such information. We will see what the website will say

Hello, I have the same problem with this machine - even the highest quality black coffee comes out to say the least. At work, I have been using Krups EA8108 for a few thousand zlotys cheaper for several years and makes coffee much better. Did the website solve your problem?

It was still necessary to check what circles fall out. Are they quite large then check the coffee temperature 1cm under the outlet is to be about 84 degrees

Hello, I contacted the official Krups website, however, I did not get help how to improve the quality and strength of coffee, maybe this is their factory defect it's hard to admit it now
If you donate to the website, let me know if they have helped

The discs come out dry but probably smaller than with EA8108. The coffee is hot enough. Well, it is not tragic, you can drink it, but the most annoying me is that a much cheaper espresso machine from the same company makes definitely better coffee. I checked on the same type of coffee at work and at home. With EA8108 coffee comes out more aromatic, meaty with better crema. In fact, without the "Dark" option, there is no reason to switch on this more expensive machine. The only advantage of Evidence is the very good milk frothing system. Unfortunately, after 2 months of using EA8908 I regret buying.
Somewhere on Elektroda someone described entering the service menu where you could set the grinding time but now I can't find it.

Welcome to the forum, I am also looking for something on this topic, because my krups also has this symptom. just as if the coffee grinder was too short. I once had a krupsa ea8250 and there you could actually change the settings of the mill as well as calibrate the piston. here at ea891d I have no idea how to do it. and this option should be there too. maybe someone something ... I would be very grateful (and others certainly too)

Briefly i.e. how much?

short, i.e. I did not measure time, but the cookie is certainly not centimeters and falls apart, despite the focus on "dark" and the coffee is weak. like I say - I have a comparison with ea8250. I have the impression that he grinded for 1-2 seconds longer and the coffee was black (like strong coffee) and the cookie was beaten and did not fall apart. surely 1 cm thick.

that's why I think it's a matter of setting the length of the coffee grinder. and in ea8250 I know that the service menu allowed setting from 1-5 (5 it was probably 12s)

Hello

I have the same problem, too, I had a weak coffee 4-5 s and a full cookie in the tank spits out every second coffee as if it were making two coffees from one cookie is this normal? Someone has already found out how to enter this service menu?

Hello,
I also have EA891 and the grinder had less than 5 seconds, the coffee was weak and instead of a cookie ... some coffee falls out. I don't know how to change the grinding time. Save!

I am giving you how to enter the service menu. Maybe someone will need:

Calibration
1. All containers are removed (water and coffee grounds),
2. Turn on the plug to the electricity,
3. Turn on and turn off the coffee machine,
4. With the coffee machine turned off (but with electricity) press (and hold down) espresso cappuccino tea in turn,
5. Select calibration in the menu,
6. Put the calibration disk in,
7. Put the grounds container, the water container filled with water, put the cup on the drip,
(8. We refill the grinder container with coffee - I do not know if this step is necessary, I did not pass the calibration positively - no disc),
9. Press ok and calibrates.

Hello, I'm joining the topic, I had the same problem grinding the grinder briefly, the calibration in the service menu goes to the end, however, the coffee grounds are still wet after replacing all the seals, moreover, there was a problem that after brewing coffee or after the self-test, it sprays the rest of the water from the boiler after dismantling the two-bar valve turns out to be that the double-bar is suspended what's next? pls help

Added after 29 [minutes]:

Ok, one problem from the head in the new krups is a sensor in the upper part of the housing If it is exposed, the coffee machine is really getting stupid, while the problem with wet grounds remains, even though the calibration is correct when choosing the right height of the disc, little else in the service menu, apart from calibration, there is also a grinder and the gringer option is set to 8 seconds and they actually had 8 seconds after the end of the calibration process, they still had less time.help
