sounds like a jammed impeller or blocked intake screen.

either debris in pump causing impeller to hang, or you need a start capacitor.

Humming noise is usually an indication of a bad motor.

If its the "hum" that bothers you there can be debris in the impeller, take out the pump basket, reach down and feel the plastic blades beyond the hole at the bottom of the pump, should be smooth and clean. Hair often builds up at this point and causes noise. If this is a water flow problem I'm assuming its an in-ground pool. When you "prime" the pump make sure you are pulling off only the main drain.

Your heater will not work until you fix your pump, and your pump won't work until you replace the shorted out motor.
