Pump buzzing, tripping breaker

[HenderPool]

Hello,

I have a Hayward Super Pump 700. I noticed this morning the pump, which is on a timer, was off when it was supposed to be on. The breaker had blown. I flipped it back on, restarted the pump, and all I hear is a buzzing from it -- no water moves. After 15 seconds or so, the breaker blows again.

Any thoughts on how to troubleshoot this?

I have the same issue where mine humms and will trip. Called pool store I used and they said it could be from all the wet weather and to let it dry out for a day or two. Hoping that's the issue.

Buzzing and humming could be two different things. Humming is often a sign of a failed start/run capacitor. If you are handy, many owners can replace that themselves.

Buzzing could be different. Could be the motor itself, or something else internally. First you might try checking to see if the motor shaft spins freely with power OFF. In the pump pot try to turn the impeller with your fingertips. If you've ever removed the motor rear cover, you should be able to get to the motor shaft from there as well with a wrench to see if it turns. Also with the cover off, perhaps check for any signs of electrical arcing. If the buzzing s really more like a hum, then the capacitor noted above could apply.

Thank you for this tip! I followed your advice and found a very small stem of a leaf in the impeller. After I removed it, the pump turned on and seems to be working as normal so far. Can't believe something so small caused it to stop.

That seems odd. I would think the pump would have enough torque to overcome a leave stem.

That seems odd. I would think the pump would have enough torque to overcome a leave stem.

The starting torque of any pool pump, but especially the motor on a Hayward Super Pump 700, is incredibly small.

Hmm, I didn't know that. I guess it's because the load is just water.

Pump just Hums after power outage

Hi this is Kim, In the wee hours of Thursday morning we had a power outage which of course I didn't discover until I got up around 10:00 a.m. I went about my day and then I realized that my pool pump wasn't working cuz I saw no movement in my water. So I went to the circuit breaker the switch...

You might want to track down the capacitors in case you need them.

I would get them to have if needed.

As the capacitors begin to fail, the starting torque decreases.
