What to do if my Hayward Heat Pump shows high pressure protection?
- RriverskathleenAug 17, 2025
If your Hayward Heat Pump displays a 'High pressure protection' error, it indicates that the refrigerating circuit pressure is too high, water flow is too low, the coil is obstructed, or air flow is 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 correctly, confirm the water inlet/outlet valves are opening, and check the by-pass settings.
