Hello all, I seem to be having trouble getting my Lx74 spa up and running properly. It seems that every time I fix one thing another just happens to go wrong. I just had both of my pumps removed and serviced last month and they are now running seemingly well but when I try to begin the initial start up my balboa panel is giving me a code "Dr" twice and then the third try it says "Dry". I'm not sure if it is just simply air lock or a more severe issue. Both my blowers and my jets are working, as well as the two different speeds for the jets. I'm not sure if the heater is working just yet because the spa does not run for a long period of time before shutting itself down. It is to my knowledge that those error codes are telling me that there may be insufficient water supply to the heater but when I hand loosen the pipe fittings on both sides of the heater/circuit board, water is leaking out. Also when the tub is initially powered up the blowers go on and remain on regardless of me turning them on/off via my balboa TP600 top side panel. Would you happen to know a way that I can troubleshoot or correct those error codes? Any help would be greatly appreciated.
