We performed a comprehensive mechanical repair and component replacement for a HotSpring spa in San Diego. Our team diagnosed issues with the heating system and water treatment setup to restore full functionality. We focused on replacing worn internal components and ensuring the electrical systems were operating within safe parameters. We installed a new Titan heating element, replaced the UV water treatment bulb, and updated several gaskets and O-ring seals to prevent leaks. After mounting the motor assembly and testing the electrical control board with a clamp meter, we verified that the spa light and control panel were fully operational. These updates improved the heating efficiency and water clarity for a more reliable system.
