Why is my mspa F-NA062W Hot Tub not heating properly?

If your MSpa Hot Tub is not heating properly, first ensure the temperature is set high enough. A dirty filter cartridge can also cause this, so clean or replace it. Check that the water level is at least at the minimum line. If these steps don't resolve the issue, reset the heater, as the temperature protection switch may have tripped.
