Issues such as SaluSpa not heating, SaluSpa inflatable hot tub not heating, or any hot tub not heating water, are very common and can usually be fixed without the help of a professional.
For SaluSpas, heating problems are almost always associated with water flow, filter, flow control, sensors, and error code issues rather than a broken heater. This guide discusses causes, tips, and maintenance with easy-to-follow paragraphs, well-structured lists, and working tables, so you can regain heating and enjoyment of your spa.
