Why is my mspa Carlton M-CA062 not heating properly?

Your MSpa Hot Tub might not be heating properly due to several reasons. The temperature may be set too low, so try setting a higher temperature. A dirty filter cartridge can also cause heating issues, so clean or replace it. Ensure the water level is at least at the minimum line; if not, add more water.
