Title: Jacuzzi J325 --- fault
Post by: im45us on September 30, 2015, 07:05:01 am

Good Morning,

I have a 1 year old Jacuzzi J325 hot tub that gets the --- watchdog fault way too often. Plug off and on resets but with winter coming want this gone. The repairman says because I plug it into a GFI plug that the 2 GFI's might be working against each other. I doubt that's it but will change the plug.

Any ideas what might be causing this, where to start? An on-line search says hi-lo limit might be the problem.

Thanks in advance.

Ivan

From the software/firmware standpoint term "watchdog" always refers to internal circuitry or software that monitors main circuitry or software. In case that main component fails "watchdog" suppose to reset it. My guess is that you have either board or software corruption.

  Watch dog is 90% of the time a faulty sensor with the high limit being very low on the failure rate.   You could run the GFCI cord into a extension cord and pug that in someplace else and see if it changes.

How does software get reset on these? If firmware then I assume would have to replace control board.

Problem is I have nothing close to the tub that's not GFI. I could change the plug for a month or so to non GFI.
