Why is my mspa Lite LS04U-NA not heating properly?

Your MSpa Hot Tub may not be heating properly for several reasons. The temperature might be set too low, so try setting a higher temperature. The filter cartridge could be dirty, so clean or replace it. Also, ensure the water level is at least at the minimum water line by adding more water. In case the filter pump doesn't work, refer to the "FILTER PUMP DOES NOT WORK" section.
