Need help troubleshooting pump; won't spin

[waterbear]

One other possiblity is that something is lodged in the impeller if it is not spinning freely or the bearings may have siezed up.

Every spring, I have to take off the strainer basket, remove the impeller and use a pliers on the motor shaft to break the motor free. (Be careful not to damage/score the shaft with the pliers.} That is how I free up my motor.
