Had a tech out a few hours ago to replace the board, when removing found a burnt mark on the back side causing the heater to run 24/7 with the circ pump.
New board in, tests everything and all looks good. A few hours go by and I can't log into the tub on the Balboa Wifi app so I go outside to check on things. Dead, panel shows nothing and nothing operational inside the cabinet.
I check power at the terminal block...120v to red and black and 240v across the two. Checked fuses F5 and F1 and the both are fine. Checked all the connections and everything looks good and tight.
If I flip the disconnect off and then back on I can hear the spa come to life, couple beeps and the wifi comes alive. However, by the time I get to the business end of the swim spa...maybe 10 seconds or so nothing is working. Power checks out, fuses are ok...any ideas what is going on?
