Goldline Aqua Plus "No Cell Power"

[NewToPoolAndThings]

First of all, thank you everyone for all the inputs here.  Unfortunately, I've done everything I could find. I replaced the 20 amp fuse and replaced the relay. I actually got a replacement board, but that doesn't seem to be working properly, but with it I know the chlorinator works (I also got it tested on the pool store). But that had it's own problems, you can look here if you're interested.

Does anyone have any input on what I can try next? I tested the connection (plus many more) mentioned in Seakayaker's powerpoint and all seemed in tact. I've built computers, but this is first time doing soldering and digging into connections. Is there a way to check all the connections between that k1 relay and where the power eventually gets to the power cell? I think I saw that a bad transformer could cause something like this, but don't have a clue on how to test it. At this point, I'm about to call pool guy to get it replaced just so I can get it going again. I appreciate any help!

Was this a new board? If so then the problem is likely to be in the power supply. Did you test the red and black leads going to the board for 26vdc? Did you test for AC (from the breaker) going to the board?

Hi Mark,
I appreciate the response. I haven't done extensive testing on the new board as far as checking the voltage, and to be honest I'm not 100% sure on how to do it. The only thing I've done was check the ohms of various points. I might send the new board back and grab a new one and see what happens from there. If the same thing happens, then it's likely that something else needs to be done configuring it.

Ideally I'd like to fix my issue with the chlorinator not working on my current/old board, as everything else is already set up. Though at this point I'm not sure what/how to check. On the orange cable, next to where the relay is, I did check the ohms to see if there is any resistance and it seemed fine. Are you aware of any more testing I can do on the chlorinator power? I know the chlorinator itself is in working condition. Are the any tests I can run where the cell connects to the board? Reading all the stuff online makes it sound so easy!

Soldering the post on the backside of the board worked for me. I owe someone a case of beer!!! Thank you!

Great thread. I want to add my experience as it is a bit different.
There are two different messages that show the Hayward SWG is not working:

#1: "No Cell Power" - This is usually caused by a problem with one of the solder joints on a relay on the back side of the board. I had and fixed this problem over 6 years ago and it has worked great (I also replaced the relays but that probably wasn't necessary). The complete solution is well documented here (link is working as of June 2019): No Cell Power

#2: "Cell Power Error" - This is a different problem. The problem was the SWG got too HOT. This occurred when there was direct sunshine on a warm or hot day when my 2-speed pump was going at low speed. It has taken me over a year (maybe 2) to finally figure this out. The cell was relatively new (less than 2 years). Checked out fine with a test at my local pool supply store. Problem was intermittent. It sometime would run for several days, sometimes would die in a few hours. Turning the power off of the main controller (with breaker panel) and back on, cleared the error and problem temporarily, but did not offer a temperament solution. My solution for "Cell Power Error" was to SHADE THE SWG CELL from the sun. I placed a few boards across my heater to shade the cell and the Cell Power Error problem went away. I removed the boards that shaded it, and the problem came back. I never found anyone with this solution on the internet. Most threads also confuse the two different messages.

So in Summary: It makes a difference if you have problem #1 "No Cell Power" which is well documented or problem #2 "Cell Power Error", which my solution was to shade the cell from the sun. I hope this helps people. As a side note, it is probably a good idea to shade all your pool equipment as heat and UV is one of the worse enemies for electronics, pumps, fiberglass filter units, PVC. I have been learning this the hard way (and make sure if the equipment is next to a building, there is a gutter overhead!).
Good luck!

I appreciate that you are sharing your experience but what you're saying really does not make much sense.
