Did you also check the connections for the pump, both at the board and at the pump, and check the high-speed relay on the board?

Did you check the incoming connections? That was the main problem I had that led to everything else. One of the hots was a tiny bit loose and fried the board in that area. I ended up replacing the pump and entire board because of it.

Everything seems to be working properly for several days now. I'm going to consider it "fixed-for-now." Thank you @RDspaguy and @CanadianSpaTech again for your time and effort!

No blown fuse since getting the pump up and running yesterday. I'm going to let it run for now; hoping that the fuse issue was, somehow, related to the K6 relay issue.

Thank you @RDspaguy and @CanadianSpaTech for your ongoing efforts. I really appreciate it.

I looked around the back of the pump with a mirror, but was unable to locate either FLA or amps. It is definitely not on the front-facing label.

Thanks. Your post prompted me to go back and try to reload the manual; it wasn't loading completely. There is so FLA or even amps written on the pump. It is a Gecko xp2 model 0611500-1, but I can't find the FLA searching google so far.

Thank you. The manual you linked to was not loaded completely, hence my confusion. I don't have any issue with a pump running continuously; it just didn't run at all on low speed. With the programming info, I was able to change parameters and troubleshoot. I couldn't get low speed to run in combination with any other settings. I ended up just moving it to K5 and changing the parameters to make K5 the low speed, and it seems to be working correctly now. I am going to wait and see if it still blows the fuse (again). I imagine it will, but trying to separate issues.

This other menu was accessed by holding the "lights" button, not the "jets" button. I'm guessing there's a setting in here I need to change.

I still don't see a reference to what the LL settings should be. My spa manual says that LL1 is for 120v installations, and LL2 is for 240v. The manual lists the difference as LL1 preventing the heater from running while the pump is on high speed. I tried accessing that menu again, but this time was presented with a completely different menu instead of the LL menu. Many different parameters such as 1., 2., 3., L., H., ou., E., and several others with many settings to choose from. I can't find any reference to these parameters and their settings online. Do you have a reference for these?

The ozone is, indeed, connected to p23. Jumper 1 is to use the board with 120v. It has been removed intentionally. I don't see any differences between the board and the diagram. I performed the test you suggested. Removing the red wire and moving black to C does, indeed, turn on the low speed immediately. FLA is not listed on the main pump sticker. I do have a clamp meter. Thank for trying to help. I appreciate it.

Perhaps you are looking at pic 2 in my post above, which is of the old/original board? The new board is nearly-identical, except the K6 relay looks different, and the "common" plug on K5 now runs to a second fuse before returning to the "neutral" space on the board.

What do you see that doesn't match between the diagram and the new board? They are identical from what I can tell. There was only a link to this diagram online. It was not included in hard-copy.

I have the spa hardwired to 240v, and set to LL2, which is the combination in my spa owner's manual. I don't see anything in your links or the manual for the new board that provides a settings guideline; just how to adjust the setting. Should the setting be something other than LL2?

Wiring Diagram: Pump wiring from old board, showing white wire on K5-P: New board, as currently-wired, allowing pump to run on high for around 24 hours before blowing fuse:

I own a 2015 Aquaterra Transport II. I recently had one of the main supply wires arc and the tub stopped working. The area of the arc and fried board connection was obvious, and I elected to purchase a replacement control board/box/system. I purchased a Gecko in.yj-3, which was listed as the "upgraded" equivalent replacement of the Gecko control box that was in the tub. The replacement was easy, and I made all connections exactly the same as the old board, but I am having problems since its installation. Problem 1: Originally, the pump would not run at all. On the original OEM board, the white wire from the pump was connected to K5, which is listed in the diagram as the pump 2 relay. When connected this way, as it was in the old board, there was no response from the pump. I moved the white wire to the neutral terminal, which allowed the pump to run on high speed only. If I swap the L/H (black/red) wires, the pump will run on low speed only. So, the pump seems to be fine, and it seems to be a problem with the wiring, board, or topside (topside shows only solid light/high speed or off, and goes straight to high-speed after power-up) Problem 2: The tub will run with only one speed of the pump working. Heater works fine. However, after almost exactly 24 hours, it blows the fuse (SC-20 fuse on the board) for pump 1. If I replace the fuse, it will run fine with a single speed for another 24 hours, then blows another fuse. I can't find any issue that would cause this. Other info: pump is a Gecko 120V 2-speed pump. Topside is the stock/OEM simple unit with four buttons. Any help is greatly appreciated.
