Spa appears dead—no display, no control of jets or blowers or temps.The only function that worked was turn the lights on/off. Checked all power supply voltages—everything looks OK. All fuses good (checked out of circuit). Re-seated all connectors, tightened pins. No luck. Turned off main breaker for the night. Came back the next morning and the display had the icon for the heater and the ozonator—but no other display—or control. The circulating pump was running and the ozonator was making bubbles.
Wiggled all connectors–no luck. Came back an hour later and spa and display were totally dead—no ozonator, no heater, no display.
