Hi, I just joined. I have been maintaining our pool since we built our home in AZ in 2002.
I shadowed the service people for a call or two then picked up the service myself.
I have been through 4 water changes, 3 Hayward pool cleaners and replaced 2 motors.
Other than that I just check CL, PH and Alk every week and add CL Tabs as needed.
But now my Hayward H400IDPL Pool/Spa Heater is off-line and I am determined to fix it.
Error code A0.
