Why is my mspa P-SH069 not heating properly?

Your MSpa hot tub might not be heating properly due to several reasons: * The set temperature could be too low, in which case you should set a higher temperature. * A dirty filter cartridge can prevent proper heating. Clean or replace the filter cartridge. * If the water level is below the minimum line, add more water. If these steps don't resolve the issue, it may be due to a heater or filter pump failure, requiring professional assistance.
