Why is my MSpa Hot Tub not heating properly?
- TTimothy JohnsonAug 13, 2025
If your MSpa Hot Tub isn't heating properly, consider these potential causes: * The temperature might be set too low, so set a higher temperature. * The filter cartridge could be dirty; clean or replace it. * The water level might be below the minimum line; add more water. If these steps don't resolve the issue, and especially if the filter pump isn't working, contact your local MSpa Service Center, and refer to the "FILTER PUMP DOES NOT WORK" section.
