What kind of rings fell out of the Bosh car?( ⇐ Bosch

[Christina]

Good afternoon I found 2 light-colored rubber rings, approximately 2 centimeters in diameter, in the interior of the car.
I don’t know what it is and where it fell from:(( 1 of the two rubber bands are torn.
And it’s definitely not from some kind of dishware.
What should I do? Please tell me who knows?
The sink seems to clean normally.

This is the O-ring for the middle spray arm.

Hello, I will not create the same topic, a question about this ring. I found it in the filter. Where did it fall out from or does it have something to do with the filter?

And what to do with these rings?

I found this too. And where to put it? There is a larger hole on the back wall, everything is in place on the counter part

O-rings of the upper impeller assembly.
Pull out the upper basket completely and look at her from behind carefully.
