I had spa tub that O thought required 240v, so i got this installed, leisure bay S2 spa, had a plug attached, when I plugged in tripped GFI now I have no power at spa at all, what have I blown, I thought even if spa 120v plugging into oulet that has 240v supply would still be okay.

Can some one help please/

thanks

Nope. Giving a 240v spa 120v is ok, but doing the opposite does damage. If there is a circuit board on your tub, it is probably fried. A pic of the control box innards would help.

Thanks hope these help. I do not know much about the inside box etc

Looks like a balboa lite leader? If you hooked that into 240 with it set for 120 the board, and likely the transformer, is cooked. If you poke around on the board you might be able to find the Balboa P/N. Should be a 5-digit number.

Thanks will do

Hi again, I attempted to replace transformer, and I think I have replaced ok, no difference, I have notoced on board ( balboa Lite Leader ref 52258) that a soldered in fuse on the board, and it looks like it may be blown.

Do I need a replacement board or pack, and where best to buy second hand if possible.

Thanks

You'll have to replace the entire pack. The board you have is proprietary. There are other lite leader boards available but they have small differences that might make them useless to you. Best to just switch out for a VS501 or something of the sort.
