I've used several in the past that came with used set ups. And had trouble with every one of them. One was the cheesy ceramic impeller shaft breaking several times, another was the exact problem you are describing, another was the cheap locking handles breaking at the canister body, and most of them you couldn't get a good seal between the motor housing, and canister base. So they would suck air and either quit completely, or have a very low flow. Not to mention they are a PITA to prime.
That's what I meant by(because its a Fluval)
I wouldn't take one if it was the last filter available!!!
I own 2x1+,2x2+,1x3+,2x205 & 2xFX5. They have been in service for 5-8 years, I've needed to replace a couple o rings and a few odd bits, try a new Fluval, they keep my fish alive, I've never broke the impeller shaft!
This isn't doo!
If the FX5 stays off I clean the impeller, the first time took 15 months (a test) now I clean it annually. if you check your filter with each clean it won't catch you out unexpectedly. My 205 struggled with priming because it was too close to the base of the tank. Increase the gap. Fixed. They specify a distance.
This is not a ration to you, but my experience with Fluval.
The ceramic shaft allows you to use them with Marine or brackish set ups. Bonus.
