    Why would it be switching off during the day ...

    Good Morning TFP -

    I completed SLAM a few weeks ago and during that time was suspicious that my SWG was not working. Last week - I went out to check the diagnostic numbers and the cell voltage and cell output were just a bit high - I was a bit suspect since I remembered them running about 25 and 5 ish last year.

    Anyway - I checked it again at some point and I notice the cell voltage read 33.4 and the cell output 0 - yet the power and generating lights were still on. I called the manufacturer (Hayward) and all I had to do was power it off - let it sit and then turn it back on - VOILA!!

    I checked it the next few mornings to be sure it was turning back on when the pump turned on and indeed it was turning on with appropriate numbers roughly 26 and 6 respectively.

    Last night - when I went to check on everything - I decided to check diagnostics for no reason whatsoever and lo and behold the voltage was 33+ and the output 0 .

    Is this normal? I have it set to 60%. My FC is holding just fine and my water is clear but soon enough, summer is here and I have a lot of trips planned where I will be having someone else care for the pool - the SWG cell voltage and cell output were not something I was planning on teaching !

    Thanks for any input you may have.

    That is strange. Maybe you should order a new cell if you can to have on hand. In the meantime you will just have to watch it and keep an eye on your FC

    You probably caught it during the 40% time that it is off. I don't remember the timing they use, but they all use a set time frame. Set at 60% it will generate chlorine 60% of the time. Like if the time it uses is a 2hr window it will be on for 72 minutes and off for 48 minutes. They don't make 60% of max capacity of chlorine all the time, they make chlorine 60% of the time.

    As far as the time when it said it was generating chlorine, but it was not, that is a mystery.

    SWG works like a microwave oven. Anything less than 100% makes it cycle on and off. I suspect that's what's happening, since it's generating enough FC. When you reset it, it started the timer over again, with the cell on.
