How to fix a water inlet sensor fault on a Hayward Heat Pump?
If your Hayward Heat Pump displays a 'Water inlet sensor fault', it indicates the sensor is either open or short-circuited. To resolve this, check the CN21/RES1 connectors on the board and the extension connector. If the problem persists, consider replacing the sensor.
What to do if my Hayward Heat Pump shows a high pressure protection error?
If your Hayward Heat Pump is showing a 'High pressure protection' error, it means the sensor is open or short-circuited. You should verify the CN30/HP connectors on the card. If the issue continues, replace the sensor.
What to do if my Hayward Heat Pump shows a low pressure protection error?
If your Hayward Heat Pump is showing a 'Low pressure protection' error, it means the sensor is open or short-circuited. You should check the AI/DI03 connections on the card. If the issue continues, replace the sensor.
What to do if my Hayward Heat Pump displays a flow sensor fault?
If your Hayward Heat Pump displays a 'Flow sensor fault', it indicates that the sensor is either open or short-circuited. To fix this, check the AI/DI02 connections on the card. If the problem persists, you may need to replace the sensor.
What to do if my Hayward Heat Pump shows level 2 antifreeze protection?
If your Hayward Heat Pump displays 'Level 2 antifreeze protection' because the water temperature is below 2°C and the air temperature is below 0°C, immediately stop the heat pump operation. Empty the condenser to prevent freezing. By default, the heat pump starts both the filtration pump and the heat pump to prevent icing over.
What to do if my Hayward Heat Pump shows level 1 antifreeze protection?
If your Hayward Heat Pump displays 'Level 1 antifreeze protection' because the water temperature is between 2°C and 4°C and the air temperature is below 0°C, stop the heat pump operation and empty the condenser to avoid freezing. By default, the heat pump starts the filtration pump to prevent icing over.
Why is there a large input/output temperature difference in my Hayward Heat Pump?
If the input/output temperature difference is greater than 13°C in your Hayward Heat Pump, it may be due to a lack of water. Check the operation of the filtration pump.
What should I do if my Hayward Heat Pump is in 'Antifreeze protection Cold mode'?
If your Hayward Heat Pump is experiencing 'Antifreeze protection Cold mode' due to a water output temperature below 4°C, stop the heat pump immediately. Empty the condenser to avoid the risk of freezing.
How to troubleshoot a communication problem in a Hayward Heat Pump?
To address a 'Communication problem' with your Hayward Heat Pump, check the connectors by referring to the wiring diagram.
How do I fix a water outlet sensor fault on my Hayward Heat Pump?
To fix a 'Water outlet sensor fault' on your Hayward Heat Pump, verify the N22/RES2 connectors on the board and the extension connector. If the issue persists, replace the sensor.
