Caffeo CI E970-101 - Water leaks out

Hello dear experts,

I own the fully automatic Melitta Caffeo CI. This I have purchased cheaply from Ebay. Unfortunately, that was it with the advantages.

My problem was when I bought that the machine had ground the beans normally, but then the coffee did not land in the front through the spout in my cup, but directly completely in the drip tray. The coffee powder was in the pomace container (wet-moist).

I then first completely cleaned the machine. I then read up on various forums and then completely replaced the drainage valve. I also changed the hose that goes from the water tank to the heating element. I also replaced the expansion chamber with a new one.

Now the machine grinds the coffee and everything sounds good for now. Unfortunately, the coffee powder then falls into the grounds container (powder is dry) and I guess the water from the coffee flows out from under the machine so I have a puddle.

Can anyone help me? Maybe someone has an idea.

Love
Knut
