Dale A. Posted February 5, 2023 Report Share Posted February 5, 2023 I have an old jacuzzi hot tub. Over the years I have replaced parts and have kept it going. Have replaced the heater element, different sensors etc. It does not have any place to show codes etc. just 1 knob to adjust temperature and a little red light is on when it is heating. It will work perfectly until it gets up to temperature the everything shuts down and the red light blinks. If I hit the little button next to the red blinking light it comes right on and acts normal until I check it later and it's hot but everything shut down again. ( the button changes the motor speed, turns on the light etc. It is the only control except the rotating temp. knob ) I read another post that said the pump motor might be overheating. Any other thoughts? Yes it's probably 20 years old but we love it and still looks good. Quote Link to comment Share on other sites More sharing options...
