Why is my mspa MONT BLANC P-MB04 Hot Tub not heating properly?

If your MSpa Hot Tub isn't heating properly, there are a few things you can check. First, make sure the temperature isn't set too low and adjust it to a higher setting. Also, a dirty filter cartridge can cause heating issues, so clean or replace it. Ensure the water level is at least at the minimum line; if not, add more water. If these steps don't resolve the issue, it could indicate a heater or filter pump failure, in which case you should contact the MSpa Service Center.
