What to do if the E03 alarm code appears on my Hayward EnergyLine pro?
If the E03 alarm code appears on your Hayward Heat Pump regulator, it means the pool filtration pump might not be running. Make sure that the pool filtration pump is running.
What to do if my Hayward Air Conditioner shows high pressure protection?
If your Hayward Air Conditioner displays a high pressure protection error, it could be due to several reasons: the refrigeration circuit pressure being too high, low water flow, an obstructed coil, or weak airflow. You should: * Verify the high pressure switch. * Check the refrigeration circuit pressure. * Ensure proper water or air flow. * Confirm the flow switch is working. * Verify the water inlet/outlet valve openings. * Check the by-pass setting.
What should I do if my Hayward Air Conditioner's compressor won't start?
If the compressor on your Hayward Air Conditioner isn't starting, the issue might be a missing phase or an incorrect phase order. To resolve this, check that all three phases are present and, if necessary, modify the phase order at the heat pump’s electrical connection terminal block.
What to do if my Hayward Air Conditioner shows low pressure protection?
If your Hayward Air Conditioner is showing a low pressure protection error, it may be because the refrigeration circuit pressure is too weak, the airflow is insufficient, or the coil is obstructed. Here’s how to address it: 1. Verify the low pressure switch and the refrigeration circuit pressure to check for leaks. 2. Clean the coil surface. 3. Check the fan rotation speed. 4. Ensure there's free airflow to the coil.
What to do if my Hayward Air Conditioner has a communication problem?
If your Hayward Air Conditioner is experiencing a communication problem, the issue might stem from the LED controller or the PCB connection. You can resolve this by checking the connection of the NET and NET 1 cables.
What to do if my Hayward Swimming Pool Heater shows low pressure protection?
If your Hayward Swimming Pool Heater shows a low pressure protection error, it could be due to weak refrigeration circuit pressure, weak air flow, or an obstructed coil. Verify the low pressure switch and the refrigeration circuit pressure to determine if there is a leak. Clean the coil surface, verify the fan rotation speed, and ensure free air flow to the coil.
