If your MSpa Hot Tub is not heating properly, it could be due to several reasons. You may have the temperature set too low; try setting a higher temperature. A dirty filter cartridge can also cause this issue; clean or replace the filter cartridge. Make sure the water level is at least at the minimum water line; if not, add more water.
