I have a 1.5 HP variable speed Blue Torrent pump which is wired into a light switch. Yesterday I flipped the switch before actually turning the pump off and got the low voltage alert on the screen. I flipped the switch back on and heard a pop from the pump, now it appears as though the pump is no longer receiving power. The display and LEDs aren't lighting up and there's no sound from the pump. The breaker is still on and electricity is making it past the switch because my salt cell is hooked up to the same switch and it has power. Is there an internal fuse or something for me to check?
