    Question New Motor, only hums when attached to pump! HELP!

    New motor runs perfectly until it's hooked up to our pump, then it only hums.

    Not sure all the info you need... in ground pool... 115/230 motor.

    Any thoughts would be helpful!

    thanks!

    What is the voltage to the motor, 115 or 220?

    With the power off reach through the pump basket and try to spin the impeller. Is it seized?

    need to make sure the pumps not locked up or in a bind when coupled together. if thats good but still will not turn check to see if the motor is correct to your voltage and that it is single phase not 3. also look to see if its level with the pump and no shims are needed. hope this helps
