Why is my MSpa Hot Tub not heating properly?
- Mmichael29Aug 3, 2025
Your MSpa Hot Tub might not be heating properly due to several reasons. The temperature might be set too low, so try setting a higher temperature. A dirty filter cartridge can also cause this issue, so clean or replace it. Ensure the water level is at least at the minimum line; if not, add more water. If none of these resolve the issue, it may require referring to the section regarding when the filter pump does not work.
