    New Pump Not Running?

    Hello and Thank you in advance for any help!

    I'm new here so if this is in the wrong place or previously posted forgive me.

    Inground spa/pool
    I have just replaced a 1.5hp motor with a new one after watching the old burn up.
    put new motor in exactly as old came out, all went well.

    Now when I push the button to turn on the air blower & pumpfor the spa, only the air blower comes on so I get air flow through the jets but no water.
    They are both on the same circuit so I know there's power.
    They both work off the same button, so I assume the button works (I hope, because it is set in concrete)
    Motor does not humm at all, just does not go on.

    Any other ideas as what it could be?

    Thank You
    B

    hi, welcome to tfp!
    Did you check the back of the pump for an on/off switch? Did you fill the pump basket with water?

    Interesting... Can you post a picture of the pump and the wiring?

    I wouldn't suppose you replaced a 120v motor with a 240v motor?

    My guess is that there's a fuse or breaker after the switch. and it's blown or tripped. The switch could actually be pulling in a pair of relays and the pump one is where the problem is. Pictures of the pump and the equipment will help.

    Re: New Pump Not Running?

    Do you have a meter with which you can confirm power to the motor terminals? Assuming that it is wired correctly at the motor, power to motor and motor not running = bad motor. No power to motor = problem further upstream.

    Also, make sure there isn't a disconnect switch over by the motor still switched off. I've done that before.
