Little giant external pump buzzing help

[Victorp]

My little giant pump suddenly started to produce a loud buzzing sound does anyone know why or how I fix it? Is it over heating? It is still pumping water fine.

I unplugged it and plugged it back in and it took a while for it to start pumping water. I unplugged it again and used an air duster to clean out the fan and tried to cool the motor down because it was really hot and when I plugged it back in it pumped water smoothly but I still have that buzzing sound.

is it like a humming buzzing sound

[Victorp]

yes maybe I need to oil it?

[Victorp]

the sound never existed until now.

[Ogrodii]

yeah I would lube it up should do the trick

figured out the problem I opened up the pump and a stupid mts managed to get through the over through all the filter pads and get sucked into the pump...
