Maxspect XF350 help needed

[hrdneglcry]

I have a duo maxspect xf350 which has been running on alternating ocean gyre mode for a few months. But now one pump was making noise. I pulled it and took it apart. Not much by way of gunk. The noise continued and now it just stopped working. I checked to see of I had it back together correctly. And it seems alright. But I can feel it vibrating but it will not work. Any tips? What is making not work?
Also these run as a pair and I'd like to run the other one full time but I do not know how to make the adjustment. If anybody can help please post.

These have ceramic bearings that wear out and need replacing.

Ceramic bearings in the motor?

Ceramic bearings in the motor?

The Motor block is a sealed unit with a floating hub/rotor and ceramic "Bearings/bushings" in it. These wear over time and do need replaced. If you havent removed the rotor from the motor block to clean it, thats also a possible cause.

I pulled the shaft out and cleaned the whole thing. Maybe I need a new motor. Definitely still making a noise when running. I thought it was a snail stuck in the impeller but I can't find anything in the impeller. Have read ithers have had noise and cleaning helped. Also people replace the bushings on the shaft.
