Here is something strange: My tub is wired for 230 but is only drawing 115. I have the tub running on full speed with the heater and it only shows 115 on the tub side of my GFCI and 230 on the supply side. I took the GFCI out(just for testing) and now the 115 goes all the way back to the junction box in my house again with 230 on the supply side.

Is this normal? Should my heater be running at 115 or 230? It tests out at 115 on both side of the terminals when the heater should be on.
