Shawnf222 Posted September 30, 2020 Report Share Posted September 30, 2020 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 Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted September 30, 2020 Report Share Posted September 30, 2020 What Balboa system? (BP, VL, VS, El...) What balboa topside? How cold is the water you are refilling with? Quote Link to comment Share on other sites More sharing options...
Shawnf222 Posted September 30, 2020 Author Report Share Posted September 30, 2020 Bp501/601 topside is TP800 first time I tried refilling it was 58degrees F yesterday I used more hot water because I thought it would change the “possible freeze” and it was reading 72degrees and the “possible freezing still happens.

CanadianSpaTech Posted October 4, 2020 Report Share Posted October 4, 2020 J29.... Heater Disable Switch Connection. If J29 is shorted by any means, the heater will not run until J29 is no longer shorted. If J29 is shorted during power-up “J29” will appear on the panel. The message can be dismissed with a button press, and is the only control panel notification of J29 being shorted. No message is displayed if J29 is shorted after power-up, but the heater will not run until J29 is no longer shorted. J29 expects a switch closure (not a voltage) as the command signal. In some areas, a local power company may offer discounts based on voluntary “power shedding” devices that may be installed in conjunction with the spa. Can you post photos of the circuit board as well as the schematic on the inside cover. @RDspaguy Your the Balboa guru any thoughts on this.

Shawnf222 Posted October 4, 2020 Author Report Share Posted October 4, 2020 Just curious what it means by “shorted” I just put a new circuit board in this spring. Worked perfectly. Then now this and all I did was empty and refill. I’ll send pictures tomorrow of the board and inside cover. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted October 5, 2020 Report Share Posted October 5, 2020 Never ran into that before. Looking forward to pics, as I am not even sure where j29 is off the top of my head. I'd say check j29 and then pull the board and check for water, burns, corrosion, or debris on the back. I didn't read the whole thread, so maybe you did that already.

Shawnf222 Posted October 9, 2020 Author Report Share Posted October 9, 2020 J29 is just a small pin that nothing has ever been connected too. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted October 9, 2020 Report Share Posted October 9, 2020 I don't see any signs of damage on that board. But I notice that the aux freeze is right next to the vac (j29). As your system is showing shorts on both circuits, I am inclined to say it somehow got moisture on that part of the board. Dry it thoroughly and clean it with a toothbrush to remove any calcium deposits. If the issue continues, I guess you will need a board.

Martin rice Posted February 20, 2023 Report Share Posted February 20, 2023 on my board J44 is labelled VAC. is that vacation? and should it work in the same way as J29 mentioned on this thread Quote Link to comment Share on other sites More sharing options...
