read the post i have...just before yours...no need to replace the board....not sure if you maybe did not see my post about repalcing the capacitors

Ok, so this seems to be a common question with owners of sundance hot tubs. I will answer the problem and explain why it happens. On the main circuit board of a sundance tub, there are 2 large capacitors in the center of the board. These 2 capacitors act as a filter for electricity which is mainly used on start up. A capacitor generally has a life span of about 2,000 hours, and when they start to go bad, they either will leak or buldge on the end. The buldge may be ever so slightly, but it is indication that the capacitor is bad. Again these are mainly used on startup when they are charged with a higher voltage and "blast" of electricity. If the capacitor can't handle it and "purify the current, it will trip the board. in turn this is why you see the watchdog code. you will notice when looking at these there are a few numbers on the side. when you order new ones keep in mind those numbers. but you need to change is the voltage. The current one is either 20 or 25v......buy one for 35v and use that as the replacement. yes this is ok...just means the capaciter can handle better voltage and will last longer. I believe this is something sundance overlooked when making the boards (lifespan and improper voltage) bot capacitors should run about $6. You may have read about a blow dryer trick, and everyone says this is not possible to make it work, but they are WRONG. What the blowdryer does, is apply heat to the capacitor which warms the gel like substance inside, the heat forces the gel back to its original place and shrinks it back so the electricity can flow---i forget the technical name, but if it is not severly shot, this blow dryer trick will work, either until the tub is put under heavy load or the power goes out. this usually only happens in cold weather, as when it is hot out the capacitor is warmed enough by the outside air temp. to replace the capacitor your self you will need a soldier gun, soldier, and the cloth like strip to pull the older soldier when removing the old capacitors. keep in mind the positive and negative side, and that direction should be the same for both capacitors. with out cutting off the new capacitor wire insert them in the open holesben them slightly to hold in palce and re- soldier. have a good tip soo it does not splatter, ensure you have a steady hand and do not over do it! once secure in place take a wire snip and cut off remaining leads and make sure no ther connections ar touching where you soldiered. replace board in control unit and restart------of course shut the power off at the breaker before doing any of this. it is not necessary to remove the board completely, just enought to flip it down forward. Hope this helps, i am sure there will be critics----hot tub repair companies as they will advise to buy a new board.---keep in mind hot tub reapir people are not electricians for this type of job...maybe plumber/electrician for household stuff.....they are there to make money and sell you expensive stuff to make a living. If you don't feel comfotable doing it yourself, simply take a picture of the wire connections, remove the board order the new capacitors and take to a tv/ electronic repair shop and tell them you want the 2 capicitors you bought swapped with the old-----no need to tell them anything else or even for what it is for and they should do it for a nominal fee. this litterally takes less than 5 min. take it home look at pictures and hook it back up. Again this i believe was an oversight by sundance in these earlier models and is a very easy fix,,, don't fall fo rthe new board stuff. In addition if you do the blow dryer trick other things such as the light and sensors may not operate as they are supposed---you may see erratic light changes, or the display saying their is air in the system---this is caused by the current not being pure as it passes through the defective capacitor that has been "over ridden" Hope this helps, i know i will recieve critism, but guess what....i am right, i have done it, i have knowledge of electronics, and it works!
