sump pump repair
My problem is with a submersible sump pump. Flotec FPSC3250A. When it kicks in, I can feel that the motor wants to run, but the impeller doesn't want to turn and the housing gets very warm. If I give the impeller a little push, it starts to turn at what seems the normal speed. Does anyone have any ideas?
Thank you

Just a guess. Any dirt/rocks present. Maybe getting ready to fail. Can you post some pics? Thanks.

no rocks or any kind of blockage. I've got the base off and have easy access to the impeller

dry bushing in motor?
dirt inside?
Why risk a basement flood. Replace it.

I believe those things are filled with oil. If you decide to open it do it in a large pan.

Is there a hump on the side of the motor with two screws holding the cover on?
If so that's the capacitor.
It gives the motor a kick in the butt to get started.

Sounds like the capacitor (if it has one) When they go it wont start but will start if ya give it a spin. Usually mounted on the side of the motor. Easy to replace also.

OOPS. joecaption beat me to it while i was typing. also saw it is a submersible. Not sure where the cap is, probably inside of it.

I took the top off and the capacitor is there. It looks a little distorted (hump in the middle like someting blew up inside the casing.) I'll see if I can find a new capacitor. Thanks guys

Replacing a capacitor is usually pretty easy, but make sure you understand how to discharge the capacitor before removing it. Lots of videos on You Tube to show how to properly discharge a capacitor. It can really hurt if the capacitor discharges through you. Many "dead" capacitors still hold a pretty good charge, better safe than sorry.
