I have a Hayward aqua troll SWG, I turned it on for the first time this spring and the no flow light stays on. I had to buy a new flow switch for it this year as the one last year the wire got cut. All I did was unscrew the other one and screw the new one on. It doesn't matter what kind of flow switch it is does it? I figure they all should be about the same. I also read that you should make sure the arrows on the flow switch is facing same direction as the flow of water, but I didn't see any arrows on the switch it self.
Anything else I should look for? The wire looks good and no damage to it, everything else is connected properly. I hate to buy a new switch if it is something simple I'm missing.
