  Phillip BurnsAug 17, 2025
  If your Hayward Heat Pump displays a high pressure protection error, it could be due to several reasons. The refrigerating circuit pressure might be too high, the water flow could be too low, the coil might be obstructed, or the air flow might be too weak. You should check the high pressure switch and the refrigerating circuit pressure. Also, verify the water or air flow, ensure the flow controller is working properly, confirm that the water inlet/outlet valves are opening, and check the by-pass settings.

  If the Hayward Heat Pump shows a low pressure protection error, it might be caused by refrigerating circuit pressure being too low, weak air flow, or a coil obstruction. Check the low pressure switch and the refrigerating circuit pressure to see if there is a leak. Clean the coil surface, check the fan rotation speed and ensure free circulation of air through the coil.

What does it mean when my Hayward Powerline EcoPac 81502 shows a level 1 antifreeze protection?
- M
  Mike PittmanAug 28, 2025
  Level 1 antifreeze protection on your Hayward Heat Pump indicates that the air and inlet water temperature are too low, posing a freezing risk. Turn off the heat pump and drain the capacitor.
