skitty4gzus Posted September 15, 2022 Report Share Posted September 15, 2022 I have a 2014 caldera Niagara. Apparently sometime in the last week it stopped working. There’s 240 volts going to the spa but the topside control is dead. I opened the side panel and inside the board there are 2 small red led blinking. One says spa power and the other one isn’t labeled. They’re both blinking rapidly and do so as soon as you turn the spa on. It never turns on the control panel or pumps. Water is cold and has been off for a bit. Any help would be appreciated, thank you Quote Link to comment Share on other sites More sharing options...
Couch67 Posted September 15, 2022 Report Share Posted September 15, 2022 Hi, I would get a manual for the spa if you dont have it handy, to determine what the flashing leds mean. Hopefully its something easy like a blown fuse to the pump. Quote Link to comment Share on other sites More sharing options...
skitty4gzus Posted September 15, 2022 Author Report Share Posted September 15, 2022 Unfortunately the manual doesn’t address this Quote Link to comment Share on other sites More sharing options...
In Hot Water Posted September 16, 2022 Report Share Posted September 16, 2022 Well...the other one is labeled, and may be "Controller Unplugged", or "Limit OK". Either one sucks. It may be a popped board. Can you post a pic so we can see what is flashing? We may have a solution, or bad news. Quote Link to comment Share on other sites More sharing options...
skitty4gzus Posted September 17, 2022 Author Report Share Posted September 17, 2022 I hope this helps, I’m stuck!! IMG_3827.MOV Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted September 18, 2022 Report Share Posted September 18, 2022 Post a pic of the whole circuit board with power on, close up of the small "daughter" board in the right of the second pic, the equipment area, and wiring diagram. My money is on the "daughter board" (transformer) but it's too soon to be sure. 1 Quote Link to comment Share on other sites More sharing options...

CanadianSpaTech Posted September 20, 2022 Report Share Posted September 20, 2022 To me it looks like the relay on the far left is blown. Remove that small board and look on the back for burnt and or darkened area around that relay... or the fly at J11 is holding back the power...lol Quote Link to comment Share on other sites More sharing options...
skitty4gzus Posted September 25, 2022 Author Report Share Posted September 25, 2022 Here’s a picture of the front of the board and the back side. I’m assuming something burned up at the top of the board? R1-R2? Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted September 27, 2022 Report Share Posted September 27, 2022 That board is fed from 2 breakers, are both on and sending proper voltage to the spa? I see no obvious signs of damage, so still suspect the transformer board. The fact that power is flashing and no topside or pumps says power issue to me, so likely breaker or board. Check all wiring for damage/ loose connections. Check fuse on lower right of main board. Verify proper wiring. Quote Link to comment Share on other sites More sharing options...
skitty4gzus Posted September 27, 2022 Author Report Share Posted September 27, 2022 Can you explain how to check for voltage at the board? I’m assuming I’m checking spots on the gray bar there. Visually the fuse on the board looked ok but I’ll have to pull it and check it. The wiring seems good. I had 245 at each breaker Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted September 28, 2022 Report Share Posted September 28, 2022 Yours looks to be the "geneva", center bottom wiring diagram. Test for voltage on terminal #s 2 to 4, as well as 5 to 6, 5 to 7, and 6 to 7. Post results. Quote Link to comment Share on other sites More sharing options...
skitty4gzus Posted September 28, 2022 Author Report Share Posted September 28, 2022 I tested spots 2,4,5,6 and each spot to ground had 120 volts. I tested it that way before I got your reply. I’ll try your instructions tomorrow, thanks Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted September 28, 2022 Report Share Posted September 28, 2022 Testing to ground is not sufficient on a 240v circuit, as you can read 120v to ground with one leg off, depending on component wiring. Have to test hot to hot, then hot to neutral if it has one (only one circuit does). Gfci breakers can lose a leg or neutral, which is what you're hoping for. Otherwise I'm betting circuit board, most likely the unavailable-by-itself "daughter board", which is the transformer/ power supply for the low voltage controls. An electronics/computer repair shop may be able to test it to confirm, and might even be able to fix it. Never tried with one of these myself, so can't give you any advice on it.

RDspaguy Posted October 9, 2022 Report Share Posted October 9, 2022 No, that's what you should have. Looking like the power supply to me. So bring it to an electronics repair shop or get a new one. @castletonia, any thoughts? Quote Link to comment Share on other sites More sharing options...
skitty4gzus Posted October 10, 2022 Author Report Share Posted October 10, 2022 Is it an issue with both boards? Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted October 11, 2022 Report Share Posted October 11, 2022 There are actually 3 boards, but 2 are soldered together and only available as a unit, called the main board. It is this one I suspect. The relay board can be tested, but is probably not the issue. Check voltage on the main power wires connecting the relay board to the main board (black-red, black-white, red-white) at the main board connections. 1 Quote Link to comment Share on other sites More sharing options...
skitty4gzus Posted October 17, 2022 Author Report Share Posted October 17, 2022 I sent both boards out to California for repair, hopefully repair…….. they’re the only circuit board repair company that would get back with me Quote Link to comment Share on other sites More sharing options...
