Hayward C48K2N143B1 electrical motor overheating and make weird noises

SOURCE: pump motor makes loud noise when pump comes on

If this is a high pitched sound, then this sounds like you have bearings that are starting to go out.  There is not much that you can do to prevent eventual failure.
The only other option that I see is that there is something causing friction inside the pump between the impeller and diffuser.

Dont run pump any longer. Could damage it further. Recommend overhaul at qualified well established pool repair shop. If unset of noise suden probally somethign stuck. If onset of noise gradual probally bearing. Kirk

If you have a crack in your basket you may have a clogged impeller. With the power off reach back into the pump through the pump pot with a long screwdriver and feel around. If it feels spongey it there you have a clog. Take the serew driver an use an oceleting motion in a counter clockwise direction this should loosen the clog then reach in with a long set of thin pliers and pull the clog out. This should fix your problem and once water is flowing your pump should quiet down.

Thank you for posting your question here on Fixya.com.

Your motor bearings are failing. It is most often caused by a leaking pump seal. It is a relatively inexpensive repair if it is caught early enough; before the shaft is damaged from the corrosive water eating into the steel. Take it to a local electric motor repair shop for inspection. It will likely need a set of 203 bearings and a 201 seal. All told, depending on the labor rates, it should be less than $75.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!

To the motor housing. This will be a green screw on the top of the wire box in the back of the motor. It will be inside the wire box but on the outside edge of the housing.
