I have a Laguna Powerjet 7000. It stopped working so I replace the impeller
and bushing. I ran fine, then when I unplugged it, and restarted it, it
doesn't pump. I pulled it apart and pulled out the impeller. Everything
looks fine. Before I reseal, I checked if it turns. Yep... until I unplug,
then replug. The impeller (still exposed) is turning erratically... almost
like it wants to backwards while turning forwards. So it kind of jiggles,
but manages to turn in one direction not achieving much.

Anyone know what's up?
