Melitta Avanza 600 / F270 drain valve replacement

Hello dear community
Problem: Grinding works, but water runs into the drip tray and not through the coffee powder.
Attempts to solve the problem:
I have now taken my Melitta Avanza apart twice and cleaned it properly and descaled it where I could. Unfortunately, the problem still persists.
As I read here in the forum, the next solution is probably to replace the drain valve. Unfortunately, I can't find any information on various sites about how to have this valve delivered to Switzerland, and I'm not sure whether it will fit my Melitta. Does anyone know whether these drainage valves for Melitta coffee machines are all the same and would be compatible with mine?
Many thanks and best regards
Moerchen

This would fit and is also delivered to Switzerland.

All right, thank you Schlawi
If I understand correctly, this number is 6769602.
Is that correct?

Exactly. You can enter your machine at various dealers (Komtra, BND) and then look for the spare part number. There are several more numbers. The valve also fits some Nivona and Miele machines. When installing, also make sure that you install the lower part correctly. The longer bar on the inside.

Great!
I even found a dealer in Switzerland who has it in stock for the number 6769600 and will try my luck there.
