Does anyone have much experience with Hot Tubs? I just hooked up a Hot tub all new from the panel to the Spa Disconnect and into the Hot Tub. To make a long story short, the wires from the disconnect to the Hot tub where all black and had to be phased and where phased incorrectly, and terminated. When we turned on the power, the light on the display came on for a second and then shut off and nothing turned on. When I opened the Hot Tub box up to troubleshoot, I noticed we had 240V Hot to Neutral and 120V Hot to Hot on the terminal bar! I made the correction to get 240V hot to hot and 120v hot to neutral, reset the breaker, and the screen did nothing. We tried pushing some buttons to get in going, but nothing. I'm now worried that we may have fried something, but no visible damage or weird smells or anything, and the breaker didn't trip the first time we turned it on when it was incorrectly terminated. I'm thinking maybe a fuse somewhere blew? I checked a few on the board, and they where good. Is it most likely a fuse somewhere that just blew after getting incorrect voltage, or is it more likely we messed something up with the board or elsewhere?

The Hot Tub is 240 volt, 2 Hot, 1 Neutral, and 1 ground connection.

Thanks!

Me, too. Providing make and model is always helpful, and is the only way to get lucky of finding someone familiar with that exact one. Their controls can be vastly different. Attaching pictures of the controls and the layout will also help us brainstorm ideas. They can be set up very differently and with different components or with the components in a different order. Hopefully, the fried the really cheap one that's really easy to get to.

Might have to bite the bullet on this one and call the manufacturer. If you can talk to the right tech, he'll know exactly what would happen if you supplied incorrect voltage. If you think you might need to go that route, don't forget that tomorrow is Friday. After that you'll have to wait until Monday, most likely.
 
So you had the hot and neutral reversed... Did you trip the gfci or the breaker in the panel. Did you check for voltage at the tub? Are there breakers in the tub panel that is under the tub?

Yes, one of the hots and the neutral was reversed. No, nothing tripped. Yes, voltage at the tub was 240v between one of the hots and the neutral. I then made it correct, and had correct voltage at the tub, but nothing was turning on.

I will get the make and model, just give me a few minutes.

I'm pretty sure that tubs that will run on either 120V or 240V have a warning about making sure it's correctly wired for the desired voltage. It also warns of what happens if it is set for 120V and 240V is applied. I don't know the spa you have but can it be either 120V or 240V?

If you found all the fuses and they all checked good then it sounds like you fried the board.

Been there. Done that. Not wrong wire but run away house generator. It put 200 some volts into my hot tubs 120 control pcb. I lucked out. It shorted two MOVS right near the 120 input on pcb. That blew the 2 amp 3Ag glass fuse. My hottub is older model. Today's may use cheaper fuse: looks like 1/4 watt resistor. Look for a "F1" etc mark on pcb if u find a resistor like device marked F on it. And it will be next to the MOVS that are there on pcb. They are round, 1/2 Dia of a dime usually. AND WILL Have CUTE LITTLE Black HOLE ON Top WHERE THEY blew. Shorted MOVS can be cut out, left out, and little fuse replaced if u r lucky like me.

I think I would go this route and call the manufacturer. I'm pretty sure he would have zapped the power supply. If so, then if he lucky the power supply will be seperate from the digital control boards. Whatever he zapped may not be that expensive to replace. If they think it just a fuse the can tell him which one and where to find it.

I will add my vote that this is the best advice.
