Spa Starts then shuts down, blinking o

[jguerrera]

Cal Spa 2100 Electronic operation about 10 years old. Control pad blinking O, unit not running. I restarted spa, runs for 30-60 seconds flow inindicator light on, heat light indicator goes on after several seconds, then spa shuts down, trys to start again on its own, runs about 15 seconds then quits, with blimking O shoowing on control panel.


I have checked filter and flow, the spa is reading about 93 degrees and is warm. I opened the panel and made sure all the connections were made, I removed the breaker and then resarted the Spa with the same results. Up to this point it has been running well, although I have bearing going in the motor that you hear when running.

A blinking 0 is not one of their designated error messages. So the spa will only run for 60 seconds max and then shut down? I don't think it's the thermal over heat on the pump motor cutting out only running for that long. When the pump shuts down does the flo indicator on the control panel shut off as well? If so does it come back on when the pump is trying to start on its own without pushing the jet button?
