Markpesci Posted January 21 Report Share Posted January 21 Having issues with my 4-year-old South Seas Spa 743D. The jets were pulsating and the Jet 2 light was flashing. I topped up the water level and flipped off the power at the breaker for two minutes. Upon turning the power back on, the jets continue to pulsate every 20 minutes or so, and now the Heat light is off and the temp reading is "- -F". Any idea what this issue could be? Wondering how much this extreme cold we're seeing might have something to do with it as well. Thanks! Quote Link to comment Share on other sites More sharing options...

Remove filter until issue is fixed. Take them out of the equation. Turn off all air injection valves. Quote Link to comment Share on other sites More sharing options...
