The limiter on my aquarite failed. The board was visibly scorched when I took off the cover. Ordered a replacement from Digikey and installed it last night.
Everything seemed to be working last night, this morning came out and checked (ran it all night) and the face of the aquarite controller was warm to the touch. The display had been showing 2800 salt previously, was now showing 4000, and another setting is showing -4000. The hayward site is down, so I'm not able to view the manual to see what the negative number might mean.
I don't remember the box being this warm before. Wondering if I did something wrong? Could I have installed the limiter incorrectly? Here's a couple pics:
