Have a Master Spa hot tub that suddenly stopped working. Getting power (220) to junction box at tub but that's it. Nothing on the tub works. I have replaced two 25 amp fuses but that didn't help. Any suggestions? Thanks.
What I would do is get a wiring diagram (schematic diagram) for the hot tub and test various points with a multimeter. But then I know electronics, understand what all the various components are for, how they *should* work, know how to read electrical diagrams, and I understand how to safely test these things.*
If you don't understand electronics, then there would be no point in testing anything since you would not know what various parts should be doing. In that case, call a repairman.
*I would estimate it would take at least two years of learning to fully understand something like a hot tub control panel. Sort of like a dentist fixing a cavity in a tooth. Looks easy, but takes years of learning!
Thanks for the replies. Not the gfci, it's working properly. I think it might be one of three other fuses that I overlooked before. One was pretty well hidden. If that's not the problem will have to call repairman.
