My Hayward Power Flo Pump Just Hums
My Hayward Power Flo pump just hums when I turn it on. Was running fine less then 24 hours ago. Any suggestions?
Take a small hammer and tap the motor casing a few times, This can “free up” any dirt / rust on the motor armature,
If tapping the pump motor a few times does not get the pump to go, let me know and I can suggest something else.

My Pool Pump Motor Is Humming
If you inspect the pool pump capacitor and gone bad, then you can replace by following the instruction here:
Place the pump motor in a vertical position and locate the plastic cap. You will see the end of the motor shaft, and there will be a slot for you to stick a screwdriver in, so that you can spin it. You can try to spin it in the clockwise direction and quickly hit the power switch on to see if it starts. If it doesn’t even after you spin it few times, then you may want to examine the capacitor.
Using multimeter, you can tell if the capacitor has gone bad or not. Take extra caution when you take it off the system as it might cause you an electrical shock. Also check the replacement part’s specification as there will be various model depending on the manufacturer.
Also check if the centrifugal switch got stuck in open position or some other foreign materials are in the way to make it partially open.
Let me know if you need more help.
