Hi all,
Novice repair person here. My Hayward spa heater (installed 2018) is not heating the water and is displaying this LO code. I have read every troubleshooting guide and watched every video I could find. My diagnostics included:
1. Cleaned the filters, even ran the pump without the filters - still LO
2. Checked wires at pressure switch for continuity - still LO
3. Checked heater for mouse damage - still LO
4. Switched out the pressure gauge with the one used on my pool filter - still LO
5. Adjusted the pressure switch for easier contact - still LO
I have ordered a new pressure switch and new pressure gauge, and will try to switch those out. I cannot get a hayward repair person to my region and no one local has experience with hayward. I'm frustrated and see lots of freezing nights on the horizon.... Thanks for any thoughts.
