Steps To Take To Fix the AO Code
If you see the AO code pop-up, the first step is to check the pressure switch next to the heating element. This part monitors the pressure in your pump and will alert you if something isn’t flowing correctly. If it has tripped, reset the switch and check to ensure everything works correctly. Inspecting your filter and skimmer baskets for any clogs that could prevent proper flow throughout the system might be necessary.

Next, confirm that all valves are open and set at the correct positions. If the motor is off or the valve is improperly positioned, this could restrict the amount of water flowing into your system and cause the AO code error. If none of these steps remedy the problem, your impeller needs cleaning. Unscrewing the panel off the front of the heater will give you access to the back side of the impeller, which can be scrubbed with an old toothbrush.
- Power down and restart: Sometimes, all it takes is a simple reboot. Turn off your heater, wait a few minutes, then power it back on. If the AO Code persists, move on to the next step.
- Check the wiring: Inspect the wiring between the blower vacuum switch and the control board. Look for loose connections, damaged wires, or other signs of wear and tear. If you spot any issues, call a professional for assistance.
- Clean the blower: Dust and debris can accumulate inside the blower, causing the vacuum switch to malfunction. Gently clean the blower with a soft brush or cloth, ensuring you don’t damage any internal components.
- Examine the vacuum switch: If you’re comfortable with a multimeter, test it to see if it functions correctly. If it isn’t, replace it with a compatible part from Hayward.
