Recently I've been hearing a very low hum in the master bathroom and closet. Couldn't figure out what it was. I tripped the GFCI in the master bath and the hum stopped. Immediately it dawned on me that a) the Hayward SwimPure Plus is on that FGCI circuit (it is the outlet by my sink and also feeds the outside outlet on the side of the house) and b) the master bath and closet share the same wall that the control box for the Hayward SwimPure Plus control box is mounted to.
Opened the outside door from the bathroom (courtyard house) and had my wfe reset the GFCI. Thyng - Thung - hummmmmmmmmmmmmmm I heard.
Opened the control panel cover and saw the standard Green power LED at the top as well as the red "No Flow" led as the pump was not running. It was pretty clearly coming from the control panel. If I put my hand on the front of the device it lessened the hum somehwta but it was still there.
Is something wrong with it? It normally stays plugged in and powered on at all times. (The inline flow switch controls whether it generates chlorine or not.) I reread the manual and don't see anythng adressing a hum, and it looks to be wired correctly.
Thanks in advance.
