EA8010 in endless loop

Hello, yesterday I changed the seals at the brewing head and since then the following problem occurs: The machine is switched on and the light for emptying the coffee grounds container lights up although the and the slider are clean. The head goes down and after a few seconds it goes up again and some hot water runs into the lower drip tray. Then the light comes on again. When I put the container and the slider back in and out, the whole game starts all over again.
If I had all this fun, I could play it for hours. All I want
is coffee.

Can someone please, please help me?

Hello,

after I had no nerves for it since my entry, I left the machine nearly 2 days in the corner. Today again connected to the mains and lo and behold... the machine suddenly works again... The
only problem I now have is that the coffee
is
quite
thin

.

Does

anyone have a solution for that

for me?
