I had to buy a new chlorine generator last year. Old one lasted 10 years. I have a big bucket of tabs from last year I use when the water is too cold beginning of the season for the generator to work.
Regular chlorox will do the trick
My Hayward heater threw an IF code. Thing was running then just quit. Tried to restart and got the IF. Blower works. Need to check the igniter, see if I’m getting 24VAC to the gas valve while it’s trying to fire, then clean the flame sensor. I ordered a new board, igniter, and flame sensor. So unless it’s the gas valve itself or a pressure problem, I should have it covered. If none of that fixes it, it’s the valve or pressure. If that’s the case I’ll have to call the propane company and out a manometer on the intake and the manifold .
I hate this crap. Just work dammit.
Since it quit in the middle of a run, and I can’t smell gas when it’s trying to go thru the light cycle, my guess is the board shyte the bed and closed the valve.
