I have a 1991 Hot Springs Sovereign. 110V. The Circulation Pump Failed. I replaced it and after figuring out that the wire diagram was wrong I wired it up correctly. When it was hooked up wrong the pump must of run backward because it kept tripping the control box. I checked for the hot wire and wired the pump up correctly. Then it ran and heated up to temperature.

Then two days later the control box tripped and has continued to trip every 3 or 4 hours. What should I check next?

The jet pump works fine. The heater heats up. The circulation pump is running constantly.

Any ideas?

What's tripping? Is it a GFI, the tub reset, or the high limit reset?

On the control box there are two red buttons. One of these is popping out. When pressed in it will continue to work for several hours.

This was the button that was popping out when the old circulation motor went bad. And it was popping out when I wired up the new pump backward. And by backward I mean the wire that the manual said would be the hot or load ended up being the neutral and the one labled neutral ended up being the load. The text described it one way and a photo showed it reveresed. It ended up that the photo was right.

I had gone through unpluging the main pump then the heater, and finally the circulation pump to determine which was originally causing that red button to pop out and kill the power. When I had it wired backward the circulation pump would start and stop and after 5 minutes would pop that red button. Reversing the wires got it working and heated it up to the proper tempature.

Now it pops that red button every few hours. The heater is hot the main jets work fine and the circulation pump seems to be working continuously until the red button pops out.

I was guessing that the heater might be overheating it or some relay or other might be weak. I am at a loss though how to determine what's wrong. I do have a basic mechanical and electrical background so I should be able to repair anything once I figure it out.

Thanks in advance for any help you can provide.

The two buttons are both basically overheat protection, one for your heater and one for the tub itself. From your description it sounds like it's the one in the heater that's causing the trouble. It's easily replaceable, but if you've got any other issue giving you poor circulation it will pop. For instance, if it was excessive scaling that did the old pump in, you might have a bunch of build up in your heater as well which would choke it and eventually overheat it once the tub was up to full temp.

You can do it either way: spend the money to replace the switch and see what happens or drain the tub and check the heater, etc.

Thanks for your help. The description of what each red button reacted to help me figure out the problem. Since I had changed the circulation pump and the red button associated with it and the heater was popping. Your description that it reacted to poor circulation helped me. I found the filter line was clogged. Once I flushed it out everything worked.

Thanks for your help!

Happy to help. Thanks for the update! " title="Very Happy" />
