Lastly, if your circulation pump is running like it should be, and your flow switch is testing as it should be, then you have a rare instance where your circuit board is misreading the information sent to it by the flow switch and your circuit board will need replaced. If you are showing any other results, then you most likely need to replace the flow switch.ĥ. If your flow switch appears visually closed, and you test across those two wires, your should be getting roughly 0 ohm's or no resistance. To test the flow switch, set your meter to ohm's. Now, if your circ pump is running and the flow switch appears physically in the closed position, then test the flow switch.Ĥ. If is not receiving voltage but it should be, then you likely have a circuit board issue. If your pump is receiving the specified voltage but is not running, then replace the circulation pump. This will tell you approximately what voltage your circulation pump should be getting. The hot tub control panels on a Sundance are conveniently located and easy to use. Next, check the service tag on the side of your circulation pump. First verify your spa is receiving the specified incoming voltage into the circuit board as well as out of the circuit board to the transformer. If it's completely open, and you have verified there are no water flow obstructions, then it is time to make sure your circulation pump is receiving power.ģ. kinked plumbing line, organic build up, partially clogged filter, etc). If water is properly flowing, then you should be able to see that that the paddle inside the flow switch is firmly pressed up against the vertical reed.If its fluttering, there may be a partial obstruction (i.e. Next thing to do is open your cabinet and take a look at your flow switch. Jeff if all the other buttons work including the warmer and cooler buttons and you have water movement but the spa will just not get warmer then 37. While it is not a 100% guarantee this is your issue, it could be a contributing factor.Ģ.

A solid red light indicates that immediate attention is required to clear or fix an error code. On Sale 6600-236 Sundance Spas 680 2-Pump Topside.

So, my question to this forum: Based on the troubleshooting I've done and the discoloration/deformation of this chip, would you conclude that the source of my problem is the PC board and I need to replace it? Apparently, this chip is a voltage regulator. I flipped the board around and noticed an indisputable dark spot where that chip is. It was surrounded by what looked like burn marks instead of the crisp green color of the PC board. There is a small integrated circuit chip adjacent to the capacitors that just didn't look right. I heard the capacitors could swell over time and you'd see a bulging at the top, but this wasn't the case. All check out fine.īy process of elimination, I suspected that it must be something with the PC board, so I decided to pull it out for closer inspection - after labeling the wires of course. I removed the WiFi module that was in-line with the control panel, cycled power and no change in status.Ĭhecked power throughout the PC board including incoming 240vac, transformer input/output, and continuity of all fuses. I cycled the power after removing the control panel connection to the PC board hoping the recirculating pump would come on, but no luck. Here are the troubleshooting steps I've followed thus far:Ĭompletely shut off power at circuit breaker for 24 hours and turned it back on. I just had the control panel replaced 6mo ago under warranty. As the title suggests, it is a 2013 Sundance Optima 880 with 240vac supply and two pumps. The stereo works, I can control the LED lights from the control panel just fine, but nothing else works. My tub has completely stopped functioning to where the panel is now blank and none of the pumps can be triggered from the control panel or by power cycling the spa.
