kentuckynet Posted June 8, 2021 Report Share Posted June 8, 2021 Hello, hopefully someone will know whats wrong with my hot tub. Hot spring model JJ Serial JJ3L2486 Lights on side of tub green solid, blue flashing, When i first plugged it up the lcd said "protection mode", only the circulation pump is running. Any thoughts on what might be wrong or what to start the troubleshooting process would be appreciated. Mack Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted June 8, 2021 Report Share Posted June 8, 2021 Remove filters. Did you fill it through the filter well? Do you have a steady stream of tiny bubbles from the heat return in the footwell? Quote Link to comment Share on other sites More sharing options...
castletonia Posted June 8, 2021 Report Share Posted June 8, 2021 2009 phase II Jetsetter. Phase II just means "Orca" electronics. If the circulation pump is running but you are still in protection mode it could be one of the sensors on the heater, more likely the hi-limit. Could also be a temp sensor, a circuit board, low water level, dirty filters, weak flow from the circulation pump. Remove all filters and make sure the water level is high enough to rule those out. If you're not wanting to have a service tech come out, the sensors are the cheapest of the parts it could be. Quote Link to comment Share on other sites More sharing options...

castletonia Posted June 11, 2021 Report Share Posted June 11, 2021 If the LCD display is dead that is problematic because the display is obsolete. Only way to have a functional display is either get lucky finding a used one or upgrading to current electronics. 1 Quote Link to comment Share on other sites More sharing options...
