Sorry for the problems you're having.

But I have question: do you know whether the board problems were caused by a voltage surge?

The reason I ask, we're seeing a number of VS pumps dying because of surges, possibly from thunderstorms. Now that Intermatic has marketed a pool warranted surge protector, I've been recommending that pool owners with VS pumps install one. I hadn't really thought about whether SWCG might also need protection. I would guess that the transformer and power supply might offer protection not present in a VS pump - but I'm only guessing.

So . . . back to my question: do you have any idea what caused the board failure?

Thanks!
