i have a J335 jacuzzi, 2007 model. went out to get in it, and it was completely dead. no lights, no error messages. by the temp, i can tell it has been dead for at least a couple days while i was out of town. While i was gone, there was a 3 hr power failure. I reset the main circuit board breaker, no change. I then went and turned off the dedicated 50 amp breaker (which had NOT gone to off position during or after the power failure), reset it, and still no change. Hot tub completely dead. I am assuming a fuse may have been blown, but i am not sure, and I could use the wisdom and guidance of this group. thanks.
