Check the pump for free rotation.

You can do this by
1. Turning the power OFF!!!!!
2. Opening the pump, removing the strainer basket, and reaching the impeller THROUGH the opening at the back of the basket chamber. If it doesn't turn freely, you may have failing bearings OR you may have debris, ranging from pine needles to coins to plastic toys to gravel that's causing problems. *

If you have free rotation OR aren't sure, this checklist looks pretty good: http://blog.intheswim.com/hayward-po...oubleshooting/
and describes a more definitive way to check rotation. If you aren't sure, after using the method I describe, go to the one they describe.

If you order parts, I'd recommend replacing everything: both capacitors and the switch AND getting a seal and set of gaskets, so you can open the pump if you need to do so. Remember to short across the capacitor terminals before handling them so yo don't get zapped.

Depending on your knowledge level, it would be better to order from somebody like IntheSwim or Inyo, who actually knows pools, than from Amazon. You have a better chance of getting the right parts that way.

Good luck!

* Super Pump have very high suction (one reason they prime easily) and their baskets tend to CRACK if they fill up with water flow blocking debris. When the basket cracks, it allows debris to reach the impeller. If you have a cracked basket
