- TTerrance BarnesAug 20, 2025
If your MSpa Hot Tub isn't heating properly, here are a few things to check: 1. Temperature Setting: Ensure the temperature is set high enough. 2. Filter Cartridge: A dirty filter cartridge can hinder heating. Clean or replace it. 3. Water Level: Make sure the water level reaches at least the minimum line; add water if needed. 4. Heater Failure: Contact your local MSpa Service Center. 5. Filter Pump: Refer to the "FILTER PUMP DOES NOT WORK" section.
