Hey
when powering up my spa after being shut off for refilling. A message comes up on the top screen “J29” then says priming. once the normal spa screen comes up the message of “possible freezing conditions” appears. And pumps cycle on and off.
the j29 is a jumper message and in the manual it says shortened durning power up and heater will not run until J29 is no longer shortened
anyone have any suggestions
Thanks
