problem with impella in FX5

[noelsfishland]

I have a fluval FX5 and I took the impella out to clean and now it is making a vibration sound I took It apart twice and put it back together and still making noise,before cleaning no noise at all.is there a special way that the impella should be in housing.it clicked in and is flush.I do not want to take it apart and make the same mistake again

Check the black rubber seal is in place on the impeller unit

The impeller has 2 nobs on it make sure they line up with 2 holes on the motor housings then put the gasket on it and install it
