I have a hayward SWG, a day or two ago the display bgean to say "cold" when i clicked the diagnostics button it showed the water temp at about 76 degrees
Today I looked at it and it says cold again and the temp shows anywhere from 45-49 degrees Actual pool temp is 75-77 degree's
I called hayward they had me shut unit off for a minute or so and then back on to see if it corrected it- but it did not it still says COLD and various temps all below 50 degrees.
We really dont have a qualified Hayward person in my area- so I figure whoever i would call out from a local pool co. will only suggest replacing the control box and thats about $500+/-
Is there a way to repair/Correct this myself???
