So I have a 2022 SX hot tub. Recently hurricane Ian really devastated the entire area and my hot tub was quite affected. I was able to restore the pump, clean the tub, fix the heater, and last thing is the board itself. I cleaned it super well, used so isopropyl alcohol to clean the dirty bits of it, there is definitely some rusting and stuff but I've definitely seen boards in way worse condition work before. My question ultimately is, is there anyway to troubleshoot the issues with the board? I'm running power to it, jumpers are properly configured, and I get absolutely nothing even showing it's trying to power up. I'm running 120v 20a, the GFCI doesn't trip it just stays on but nothing powers on the board. I have experience with soldering and testing with meters but not much. Is there anyone here with that kind of experience that could help me identify where the issue is originating from?

We have a 2009 Tiger River Spa Caspian model. About 2 years ago we replaced all the boards and button controls. It has been working great since. Tried to use it last night and found the whole system didn't have any power. Checked house breaker (still ok) and both breakers at the unit. When both breakers are on there is indication that the board is trying to power up when the pwr on indicator lights up. Then the D21 sensor shows red and it seems that something is trying to start up but nothing happens. This happens multiple times to no joy. I need to figure out what this sensor (D21) is linked to. Both main breakers are off again and I could really use some help before I call the repair people. Thanks Andrea

Folks, Have a 2002 Maquis spa, with a 1 (of 2) new pumps and a new heater. Wired myself. Ran fine for several months, now that it's winter, seems to consistently be tripping the supply (not the GFI cut-out box) CB. Have some milder weather, so testing again, but what is reasonable to expect? In "standby mode", with only the one pump on low and the heater on is when this is happening. Is this a hot tub problem, or an electrical problem? Seems to run fine, even with all pumps on, for about 10 mins, then trips the CB. Thanks!! Z

Our 1992 Hot Springs Sovereign is having intermittent power issues. After we lose power to the hot tub, it sometimes regains power after about 20 minutes on it's own-- with no telling of what is causing it to lose and regain power. We tested the circuit and have reset the breaker-- the power from our house is consistent. We would like to try troubleshooting this on our own before hiring a professional to come look at it. Any ideas are very helpful!

I have Tiger River hot tub- I am guessing it is an 02 or 03 model. The tub powers up then after a couple of hours the red Power light starts blinking and it stops heating. I reset the breakers and it works for a while and then the same thing happens. The more often that I do this the shorter the duration between the resetting of the breakers and the “Blinking of the Power light”. Maybe because the water is getting warmer in the tub? The tub never gets to the set temperature (maybe 10 degrees shy of it). I tested the thermistors- they were still good I have replaced both thermistors – same results I force purged the tub with a garden hose through the gray standpipe- same results I replaced the circ pump (The new one is considerably stronger) – same results I double checked that I didn’t have an air leek or air bubbles in the circ pump. The tub has a stereo- I have removed it and the its ac/dc convertor. I have removed the filters and tested it – same results If anyone has any advice on the next steps to diagnose this problem it would be greatly appreciated.

My wife and I want to buy a new hot tub with plenty of jet power for therapeutic purposes. I've got an old injury where I really need the jet to needle in behind my shoulder-blade for a deep-tissue massage. Many of the spas we've wet-tested just don't get deep enough. Our Hot Springs dealer suggested the Hot Spot Tempo which has two 2.5HP Continuous (5.2 breakdown) pumps. We haven't wet-tested yet. Any other suggestions on tubs with lots of power? (We're more value-oriented than a bells-and-whistles oriented.) Would I get a more powerful tub out of the Hot Springs line as opposed to the Hot Spot line? Thanks so much for your input. First time on the forum, but I've been peeking at the posts for a year.

Hey all, I'm hoping you guys might be able to help out as my limited knowledge has run out of troubleshooting ideas: I have a 2005 Cal Spa that recently stopped working. No power running to it at all as if the breaker was off (which it isn't). Here's what I've noticed: About a week before it broke, I went out to use it a noticed it was off totally. Checked breakers and everything was fine. I suspected the outdoor breaker so went back and forth switching both outdoor and indoor breakers on and off in different orders, and finally it kicked on and worked great that night. I didn't think much of it at the time... A week later I went out and same problem: no power at all, except this time tripping and resetting the breakers didn't work. I'm sure the breakers are good as the outside one is GFCI and trips when I hit the test button. I also pulled the panel off and used my multimeter to assure power was running into the tub. So now having located the problem to something inside the tub, I started to use my multimeter to check fuses, connections, etc to see if anything obvious was broken (which it didn't seem to be). However, the original transformer looked pretty ratty and dated to me, so I ordered a new one and crossed my fingers that was the problem. New one arrived today and still no luck with the power. Now, here's where things get weird: With the new transformer installed, I started going contact to contact with my multimeter trying to trace the spot in the circuit where power runs out. In the process, I noticed that if I had my multimeter prongs on the board in the spot highlighted in the picture below and set to 200 ACV, nothing would happen but power was running to that spot. Then if I kept contact to that same spot and turned my multimeter dial over to the Ohms settings, the tub will make a little "click" noise and turn on like normal. The display shows an "01" then an "11" then the default temp setting "100" and then to the current temp of the water "86", and then totally loses power like before, all within maybe like 5 seconds...I'm not sure if this is normal or not since any other time I've turned it on from being off at the breaker I have been over at the box and not looking directly at the display. A google search and manual read didn't yield anything helpful about what the "01" and "11" could mean... I'm pretty stumped at this point. Is there some faulty trip switch I'm not seeing that is getting clicked over when I adjust the power slightly with my multimeter attached? My electrical knowledge is just enough to be dangerous so I don't know what other things it could be. Thanks for the time reading though my problem and helping out if you can. I really appreciate it! -Mike

Hot Springs Sovereign; I think we got it around 2000. S/N is IQ2A2015; it has the IQ2000 controls, and is wired for 220. Two GFCI breakers- a 20A that runs the controls and circulation pump, and a 50A for the heaters and main pump. After a brief power outage two days ago, every time I reset the smaller, 20A breaker, it instantly trips. I replaced the breaker but problem continues. After the power outage, water backed up into the Ozone unit. I've disconnected the Ozone electrically but no change in behavior. I removed the metal bracket that obstructs the main board, didn't see any obvious burn spots or other indications. While the bracket was off, I tried applying power and got a steady red light. I powered off to avoid the shocking hazard while replacing the bracket, and now it instantly trips the breaker again. I've also tried powering up without the thermistors attached, but no change. They measure 11.61 and 12.64; water may still be slightly warm. Any clues? At first it was just the red blinking light syndrome; now it won't come on at all, and instantly trips the 20A breaker (the control panel light flashes briefly until the breaker trips.) Thanks- Paul

Hey Guys, I have a 15 amp 240V Waterco Portapac Heat Pump (air button model). It will work for about 60 seconds and then trips out. I have to push the reset power button and the "power" light comes on again. Turn on the jets and it will run for up to a minute and then cuts out. It doesn't trip the main power on house, just the pump itself. Any ideas? Cheers

Help! My 2004 Sundance Optima spa is lifeless. I checked power to the spa and I have power but no messages on the contol box, nothing. I pulled out fuses and checked continuity and they are all fine. I checked the transformer and I get nothing. Any ideas? Thanks
