Hello everyone,
I have a Hayward H250FDN spa water heater and now all of a sudden an "AO" code appeared . I replaced the boards a couple of years ago and now this has happened. Any help would be greatly appreciated, Thank you.
I agree with toma nova, looks great! We're in the Oak Ridge North area and thinking of resurfacing our pool, could you also forward me the 4 PB's you received estimates from?
TIA,
Jolietboy
