  If your MSpa Hot Tub isn't heating properly, start by ensuring the temperature is set high enough. A dirty filter cartridge can also cause this issue, so clean or replace it. Also, make sure the water level is at least at the minimum water line. If these steps don't resolve the problem, it could be due to heater or filter pump failure, requiring professional attention.
