Checking the water flow, ensuring the pump is working correctly, and examining the pressure switch for any faults can help resolve this issue.
Other Common Error Codes: Hayward heaters may also display codes like “IF,” which signals an ignition failure, or “HS” for a high-temperature limit circuit. Each code points towards a specific problem that can be diagnosed to ensure your heater operates efficiently.

Understanding these error codes is crucial in maintaining your heater and ensuring its longevity. By familiarizing yourself with these common codes, you can quickly troubleshoot issues and enjoy a smoothly functioning heating system.

LO Error Code

Encountering error codes like “LO” on your Hayward heater can really put a damper on your pool or spa time. Here are some of the most common error codes you might come across:

“LO” Error Code: This code typically indicates a water pressure switch issue. It might be triggered by a clogged filter, low water flow, or a problem with the pressure switch itself.
“IF” Error Code: The “IF” error is often related to ignition failure. This could be caused by issues with the gas supply, improper venting, or a faulty igniter.
“HS” Error Code: The “HS” error points to a high-temperature limit switch problem. It could be due to overheating, a blocked exhaust, or a malfunctioning high-limit switch.
“CFH” Error Code: This code signifies a combustion fan high issue. It could be triggered by a blocked vent, a malfunctioning fan motor, or problems with the airflow.

When you see any of these error codes, it’s crucial to address them promptly to ensure your heater operates efficiently and safely. Always consult your heater’s manual for specific troubleshooting steps corresponding to the error code displayed.

Causes

When dealing with the “LO” error code on your Hayward heater, there are a few common causes that could be triggering this issue. Understanding these underlying reasons can help you troubleshoot the problem more effectively.

Airflow Issues: One frequent culprit for the “LO” error is insufficient airflow to the heater. This can be caused by a dirty or clogged filter, obstructed vents, or even a malfunctioning fan. Ensuring proper ventilation and cleanliness around the heater is essential to prevent this error.
Pressure Problems: Another potential cause of the “LO” error is low water pressure. This can be due to issues with the pump, clogged filters, or valves not being fully open. Checking the water pressure and the components related to water flow in your system can help identify and resolve this issue.
Temperature Sensor Malfunction: A malfunctioning temperature sensor can also trigger the “LO” error on your Hayward heater. If the sensor is not reading the water temperature accurately, the heater may shut down as a safety measure. Verifying the sensor’s functionality and ensuring it is correctly positioned can help address this cause.
Gas Supply Problems: Insufficient gas supply or issues with the gas valve can lead to the “LO” error code. It’s essential to check that the gas line is open, the valve is functioning correctly, and there are no interruptions in the gas supply to the heater.

By considering these potential causes and doing some systematic troubleshooting, you can work towards resolving the “LO” error on your Hayward heater efficiently.
