We performed a comprehensive diagnostic and repair service on a Sundance Spas unit in San Diego. Our team inspected the internal equipment bay, including the electric water pump and the main control board, to identify specific electrical faults. We used specialized testing tools to verify current flow across the circuit board and ensure all wiring connections within the metal housing were secure and functional. Beyond electrical troubleshooting, we serviced the Jacuzzi Premium controller box and checked the integrity of the PVC plumbing unions and the filtration system. We monitored the digital control panel to calibrate temperature settings and confirmed the heater was responding appropriately to the system commands. This service restored the spa’s mechanical and electrical systems to full operational capacity for reliable use.
