Having some issues with my pool heater. Went to fire it up for the first time in a few months last night and all that would happen is as soon it tried to kick on it would light the service light and LO would be on the screen.
Since I last used it two things have happened:
1. The pool filter was cleaned.
2. The keypad on the heater was replaced by me.
Since #1 & #2 this was the first time we tried to use the heater. The new keypad was a little different looking that what was on there before. Could it be as simple as the incorrect keypad? I live in California, I know Hayward has part numbers with -CAL after them. Not sure if this means california or not. I didnt get a keypad with -CAL after it. I bought this one:
Could either of these things cause this issue or could it be something totally different and unrelated?
