    Finished vacuuming, now pump is stuck

    Hi all,

    Not sure what to do. I just finished vacuuming this morning. There was a lot of sand and dirt on the bottom (patio isn't done yet). I went to backwash and rinse, but when I flipped the pump off, changed the valve setting, and turned the pump back on, it just hummed/buzzed and doesn't turn. I suspect sand has bound it up. It was turning fine when I finished vacuuming.

    Any suggestions on how to flush it out? It's a 1.5 HP "Premium Blue by Waterway".

    Thanks!

    It could have a weak start cap. Turn power off on the pump look on the bavk of your pump motor. You should see a flathead screw driver slot. If not remove the screw holding the cover on. Now get a flathead screw driver and turn pump on and turn the shaft with the screw driver. If it takes off then you have a weak start cap.

    Another question. Did you remove the pump basket out to clean it out?. If so you may have lost the prime on the pump

    I did, but I bled the air out of the basket, so it's not a priming issue. The pump is not turning, so I'll try your other suggestion. Thanks!

    If you cant turn it or if it starts and stops again. Your motor is shot.

    Gave it about 1.5 turns with the screwdriver to loosen whatever was in there. Then if fired right up, multiple times. Thanks for the help!

    More then likely you have weak start cap. Its the round thing with the 2 wires going to it on the back of the pump. Has numbers on the side of it. Can buy one at pool store usually around 8 to 10 dollars. Try turning the power off on the pump again. If it starts on its own then your good. If it doesnt then replace the cap
