We performed a comprehensive repair and diagnostic service on a residential hot tub in San Diego. Our team accessed the internal cabinet to troubleshoot and restore the Balboa Instruments control system and the dual electric motor pumps. We addressed issues within the electrical control box, focusing on the circuit boards and wiring configurations to ensure reliable operation. During the process, we inspected and secured the white PVC plumbing lines and integrated valve systems to prevent future leaks. We also managed the internal wiring using high-quality connectors and verified the grounding for the motor units. These targeted repairs restored full functionality to the spa’s water jets and heating controls, providing the homeowner with a fully operational and safe soaking environment.
