Late last summer, my SWG got where it was working about half the time. This is the 8th summer for the unit. About 2-3 years ago I changed out the flow sensor. For pool start up this year, I bought a new cell and flow sensor. This was mid April or so. It has given me some some codes indicating low flow off and on, but it would correct itself each time and then start working. I wondered if maybe my solar panels were somehow causing it since the pump it 8 years old too. I decided it was giving codes regardless of the solar being on or not though. I was out of town from 05.28-06.07 and came home to it pretty much not working. The last day or two no lights were registering on the unit. While home at lunch today, I took the cover off the box and disconnected the cable to the board, reconnected it, and turned the pump back on. The chip was warm. I now get a "flow reversing," light, the amber service light and codes 172 and 180 again. I assume the cell or flow sensor are cooked again. Is there anything I should investigate before contacting the company where I bought the new cell from? Since it died so quickly, I don't know whether that just means simply it was a bad unit, or if something more ominous is afoot since I have changed out flow sensors before. I also have an awful time with iron each year and constantly fight that. I mention that in case it could be a contributor.
thx for any advice any of you might have.
