My 2006 Hot Springs Vanguard is not heating to temp. It stays around 80 degrees, I can't tell if it is heating at all (doesn't feel like it) or is unable to get temp above 80-81 degrees. No reset button on heater, Lim ok is green, HTR On is Red, Control unplugged is dark. Circ pump seems fine, filters seem fine. Tried several breaker resets to no avail.
I am planning on calling for service as I don't have enough of an electrical background to do any further checking, or at least much. I am just trying to get an idea of what might be wrong and a ballpark guesstimate of cost before I do as money is tight. I am in Chicago. Other than having the rear control panel replaced and a new circ pump about 3 years ago, this spa has been flawless until now.
Any thoughts much appreciated. Thank you.
