I was in the basement today and all of a sudden i started to hear a noise very similar to what a washer or dryer makes when they are done, but this noise was coming from my external pump that runs the closed loop. I checked the intake and outputs to make sure something wasnt stuck and didnt see anything. So I plugged the pump back in and the noise kicked off immediatly.
Any idea what the noise could be, its god awful and the pump isnt pushing any water.
By the way, I do not know the model as its not in a good spot for me to check, but i do know it is approxamtly three years old
