Kids pushed Jet switch on and off multiple times. No longer works. Pushing switch does illuminate the switch panel and display the jets graphic on and off. The rest of the buttons work as well (temp up/down). No signs of burnt wires or areas on the circuit board. The Jet Pump does work...ran power directly to test. Appears as though the both the switch and the pump are working as they should. Assuming something with the circuit board. 1999 Tiger River Bengal M. Any help would be GREATLY appreciated.
Well, as the title of the topic states, the circuit board in my Sundance Spa Sentry 800 burst into flames and is beyond repair. The hot tub had been turned off for around two years or so when it had stopped working for no reason. I had winterized it well and thought id try to fix the problem myself this year. i had a feeling it was a fuse problem so I went to radioshack and purchased replacement fuses for the circuit board making sure that they were lower amp so that the equipment would not be damaged and were ceramic as they had been before. i popped in the new fuses and hit the breaker. Miraculously everything began working like it had before. a few hours later i had the hot tub filled and the pump and heater were just fine. after the hot tub had heated up a bit i thought i would make sure that the jets were still working. about 20 seconds after the jets had started the hot tub shut down. I thought it might have been a fuse as i had put a 1 amp fuse where a 1.25 amp fuse was needed, as well as an 5 amp where an 8 amp was asked for. After shutting off the power i went to the panel inside the hot tub to find smoke bellowing out of it. upon looking inside there were huge black burn marks all over the circuit board, some with exposed copper. oddly, I'm not so sure it had anything to do with the fuses i put in because the burn marks were not on the fuses or contact points for the fuse. I just ordered a new board and want to make sure that my $400.00 investment won't be for nothing and that the new board will not fry like the old one. the board that burned out was a 6600-014 and the board i am replacing it with is the same, a 6600-014 Spa Circuit Board for Sundance® Spas any ideas?? Thanks Again,
Hello - We have a Sundance 850 series 'Marin' hot tub that had a few issues in the past (see post: http://www.poolspaforum.com/forum/index.php?showtopic=26961&st=0) We resolved our previous problem by replacing the circuit board and all of the filters. After we did this in the spring last year, the hot tub worked for about 4-5 months but then just quit working. It gives us the awful "Watchdog" (----) error again. We did some tests and think the circuit board is bad again. So, recently we actually paid a Sundance hot tub tech to come out to diagnose the problem, as we did not want to keep replacing the expensive circuit board every 4-5 months just to get it to work. We figured there must be some underlying issue corrupting the boards. The tech determined that he wasn't really sure what the problem was but thought that we could start by replacing the circuit board and topside and then maybe the remote topside too if that didn't work. I gave him the old board we took out a few years ago (yes, I kept it!) in case that helped him diagnose and he said they both have the same issue. FYI - He did say that he thought one little spot in the topside might be getting a little warm. Also, when he was there, the hot tub was able to start ONCE, but then he couldn't get it to start again. I really don't want to pay to replace of those pieces as a trial and error type "solution" to the problem. He said the temp sensor is good. He looked at the capacitors on both boards, we kept the old circuit board too, and said they were not swollen and look fine. The tech was also unable to read the history/memory to get any other clues as to what could be the problem. So much for hiring someone to tell us what was wrong...ughh! (FYI - Also, in our previous problem - see link above-, we also had the breaker tripping and the tech that just came out said that was due to the ozenator so he just disconnected it since it's an option feature anyway and not required to make the spa work.) Before we buy a new circuit board or any other parts, do you have any idea if just replacing the circuit board will make it work? If it is going to cost A LOT to repair (we plan on doing the work ourselves) in parts, then we may just get rid of the tub completely. I've also seen some refurbished circuit boards online. Has anyone used a refurb board and do they work ok? I noticed some come with the Eprom and some don't. (I was told you can install your current Eprom into the refurb board fairly painlessly.) Any experience with this? THANK YOU THANK YOU THANK YOU for any help, advice, experience, suggestions you can offer!

Hello, i was trying to get my Balboa VS501Z hot tub running, but i wanted to make sure that i have the correct Amps. The back says 16A/32A, So would i set the circuit breaker to 40 to cover both 16 and 32? Thanks in advance for any and all help
