Need help from Koralia owners

[rhinox]

I took apart my koralia 3 for cleaning and didn't notice that it had two little washers (one white and one black). Fortunately, I didn't lose either but I don't know where they used to go. I think the black one goes on the bottom side of the propeller, can someone confirm? Where does the white washer go?

Thanks so much in advance everyone!

It goes down inside where the shaft meets the plastic. Basically the same as the black one, but on the other end of the shaft

Black one inside the unit, white one on the end of the shaft.
