hot tub down

[thearm]

My emerald tub (699 classic) suddenly stopped working. The display panel is dead. I checked the GFI breaker and it would fault as soon as I turned it on. I checked the voltage coming in to it and it was good. Nothing coming out so I bought new one and replaced. I now have voltage coming out of breaker and to the tub going into the power pak. Nothing will turn on and display panel is dark. Am I missing something obvious or is it time to call a tech? Tub is 5 1/2 yrs old and we have never had any issue with it at all. Any and all input is appreciated.

 If you have 220v coming into the spa the first place I would check would be the fuse on the board or by the terminal block where the power comes in.
Usually a 25 or 30 amp fuse, then go from there.

Jim,
Good call, fast acting fuse on circuit board was blown. Replaced and it blew again. I'm guessing I have a dead short somewhere on the circuit board. Talked to tech this morning and he said to call him Monday morning in office and schedule appointment. Thanks for your help.
