marshall9720 Posted March 30, 2021 Report Share Posted March 30, 2021 I just bought a home with a j245 jacuzzi hot tub. After a few months the control panel display started blinking one number at a time. So if the temperature is at 100 degrees, only one number is displayed at a time (i.e. the 1 first, then the 0, then the second 0). There is no error code that I can find that matches this and I can't find any info through a google search. It seems as though everything is working fine. Does anyone know what this means?

CanadianSpaTech Posted March 31, 2021 Report Share Posted March 31, 2021 Never seen that before. Would be leaning towards the topside LCD screen malfunction but who knows. Would have to plug in another topside to verify. Perhaps post a short video. 2 Quote Link to comment Share on other sites More sharing options...
ciderjack Posted March 31, 2021 Report Share Posted March 31, 2021 The problem is with the board. Sometimes you can reset the spa and it will work for a while, but it will come back. It is not an issue other than aesthetics, so if you don't want to pay for a new board, it won't hurt anything. The board sends the signal to the display, and typically it happens so fast, you don't see the blinking numbers. The board is sending the numbers much slower, so now you see them as they are sent. 2 Quote Link to comment Share on other sites More sharing options...
