Cleaned Koralia, found black washer

[submersible]

I just gave my koralia 4, and koralia 4 evo a vinegar bath, and found a black washer in the bottom of the bucket. Can't seem to find out where it fits in.

Anyone know?

Thanks!

i think it goes at the bottom of the pump under the impeller shaft

Ok, I have the same problem and would like some clarification, does it go on the magnet side in the hole?

Under the propeller there should be a white washer. The black goes under it. So it goes propeller, white washer then the black washer that will sit against the magnet.
I just had the same issue. If you lose the washer hydor is really good at replacing them for free, just call them up.

This washer snaps on to the side of the propeller that faces inside the powerhead. Without it, the koralia can make some annoying clicking/grinding noise when it is on.
