Krups EA 8050: Coffee Leakage Inside Machine & Bubbling During Brew Process

Hello.
I had a problem with the express machine. I turn on the coffee machine, choose coffee and the grinder switches on, they had coffee and it starts brewing coffee. Only some of the coffee is poured into the cup and some are leaking somewhere in the coffee machine. Another symptom of the same is that, including cleaning, it all flies into the drip tank and only during rinsing water pours into the cup. I started to disassemble the espresso machine and the only thing I observed was that while brewing coffee, in the place where the piston squeezes the coffee disc, you can see the bubbling from the side. And this gurgling can also be heard after brewing / pouring coffee. Does anyone have any idea? Because I'm going through a bend ....
Thank you and best regards
Clove

Double tap valve, piston seals and so-called Barista or bottom piston. These items probably need to be replaced ..

And such a question, what costs could it be? And am I able to exchange it myself or does it have to be a service?

My statement was purely hypothetical, that you described the problem, no one can diagnose it 100 percent .. I suggested where to look for the reasons first ...
The leak matter itself is very simple - We look where it flows and replace this element.
Personally, I would like to replace all gaskets in KRUPS, as you can hear bubbling, I would suggest comprehensive cleaning of the coffee grinder, because this bubbling causes moisture in the grinder and its damage at a later stage.

O-rings themselves can be commissioned to sealing companies - The cost depends on the company and the material used, but please do not use ordinary silicone - It does not work in the long run.

Other gaskets, unfortunately, need to be purchased from the manufacturer (or agents) and unfortunately there are a bit higher costs.

Naturally, you need to get a screwdriver T15, T20, T10 and sometimes T8, additionally you need a certified grease resistant to water and temperature - I recommend it with the addition of Teflon.

The forum, as the department suggests, deals with small household appliances defects, not divination; p But seriously - No one can really estimate your manual skills online.
We are happy to help as much as we can but we are not liable for damages when: "oops, broke because I was too tight"

The coffee machine is taken apart from all external casings, so I will try to see where the leak is from and possibly take a picture and post it.

Possible O-rings and some gaskets are able to replace myself, until such a left one is probably not

As for the risk of damage to something, I am aware of it and will try to repair it.

Hi,
I'll connect to the topic. I have a problem with coffee leaking under the coffee machine. Initially, it looked like a large amount of water on the boiler (where the brewing unit enters) because it was leaking up when pumping water. Exactly here marked in red:

After reading many posts, I decided to replace the seals and clean the machine. I cleaned the brewer strainer, old coffee grinder and the whole coffee machine in general. I dismantled the piston and replaced the seals. One by one I undressed the boat (I unscrewed the piston and pulled out the sieve) and here I have a problem.
The seal looked like it was pushed in too far. It was inserted like this:

Looking at various topics on the Internet I have not found specific information on how to set it up.
How the gasket should be installed in the Krups EA8050PE espresso machine.
Just like number 1 or number 2



And which side up or vice versa:


I put it on as in picture 1 and the larger part at the top. I also replaced the brewing unit gaskets (what goes on the piston) and you can see that the water does not collect on it anymore. However, there is still water with coffee under the coffee machine and a little to the cup but not much.

It should be mounted as in picture No. 1.
As for the leak, all that remains is an attempt to start the espresso machine without a side casing and a visual assessment of the leak.

Tests without casing and coffee (even though I click coffee to make) do not show leaks anywhere. Only what a lot of water (as I make coffee is coffee) is collected in a tray. I checked the piston in the 2 bar valve plus this small piston in the middle and it goes without problems. Still, I cleaned it.

Hello,
Looking at the espresso machine without the housing, there are no leaks anywhere.
The problem seems to me in the amount of ground coffee through the grinder. Grinding takes about 6-8 seconds and the coffee spills a lot until it does not fit in the brewing place and it spills over the coffee machine. How can this be adjusted? Reduce the amount? Is that a matter of coffee?

I write a little late but I managed to get it right.
For others for the future.
I replaced the O-rings on the double-tap valve piston and generally for the double-tap valve. The problem is gone.

Where did you buy the O-rings and grease? e.g. north.pl?

I bought boiler gaskets and grease:

And I selected the other O-rings at LeroyMerlin (to size).

Hello. I have the same problem. The leak is exactly there.
At first I replaced two o-rings from piston with new but the leak didn't stop.
So, I saw better the procedure and I observed that the piston is going up when the coffee is coming to my cup.
See the piston. You will see that the piston is coming up. So in my case the leak is not from the two o-rings on piston.
But I can't find why is hapenning this.
I can't find the solution.
Is here someone who can help?

I bought a repair kit and my friend replaced it. I have the impression that the pressure is too low anyway. A different taste of coffee. The last time KRUPS has collapsed shelves on the website, they say that they are disposable.

Hi George, it can normaly be various causes, normaly is a pump problem, you have to repair pump with sealant bowl and kit or a new one.
It can be to a flowmeter problem or it can be the spring inside hidraulic with metal ring out or degradated inside.
