Hayward Pump voltage?
Need help reading out voltage for pump. I have two wires at 115 vac each then the ground. The pump hums, just trying to figure out if it is supposed to be set at 115 or 230.
Its is a Hayward Superpump. Rated for 230V or 115VAC. The motor spins fine, it just hums when you apply power and turns off after the thermal protection kicks in. The motor body itself is very hot to the touch afterwards.
So two wires with 115V each is = 230. Is that right?
Its a pool pump
And the motor hums with it disconnected from the rest of the assembly.

read the voltage at the two wires DO_NOT USE GROUND AS A REFERENCE what you read as voltage at the two wires is what your voltage is example red and black are usually 230vac when phased together if one wire is white, then suspect a neutral
Source(s): if you have voltage to the motor and all it does is hum, then your motor is bad - B-NotableLv 61 decade ago
It sounds to me like the motor is not wired for the voltage you are connecting to it. Ok you obviously have a volt meter. I agree with the other person check the voltage between the 2 insulated wires not ground. This will give you either 120vac nominal or 240vac nominal. You say your pump motor is rated 230 or 115 vac that means it can run on either voltage but will require different wiring for each which will be shown on the data plate on the motor. To change wiring from one voltage to the other is just a matter of switching a couple of wires to a different terminal underneath the wiring cover.

The voltage is correct for a single phase 240/220 volt pump. Since it just hums and does not operate. Disconnect the motor, remove it and try to turn the shaft by hand. If it moves with little effort and seems to move freely, then check the pump itself for movement. Your problem is one of 4 possible problems.
1. The motor is seized.
2, the pump is jammed.
3. the pump is broken.
4, The motor is shorted.
In any case, the unit needs to disassembled and repaired. This is best done by a qualified professional who understands the system.

need more info . . . what is the pump for? is it a submerged pump? or a centrifical pump? do you have access to the wiring in the pump or is it hermetically sealed? what is the model number and what does the the rest of the nomenclature read? a humming sound, with no spinning of the impeller, is a good sign that the pump is dead. have you tried ohming it out to check the resistance in the coil?
