Hayward pool heaters are known for their reliability and efficiency in maintaining the perfect temperature for swimming pools. However, like any complex system, they can sometimes encounter errors or malfunctions. Understanding these errors and their corresponding error codes is essential for troubleshooting and ensuring the optimal performance of your Hayward pool heater. In this article, we will explore some of the common error codes you may encounter and provide guidance on how to resolve them.
Understanding Hayward Pool Heaters
Before we delve into the error codes, let’s briefly understand how Hayward pool heaters work and why they are crucial for pool owners. Hayward pool heaters utilize advanced technology to heat pool water, allowing you to enjoy comfortable swimming temperatures even during colder seasons. These heaters use either natural gas or propane as a fuel source and employ a combustion process to generate heat. The heated water is then circulated back into the pool, maintaining the desired temperature.

Common Hayward Pool Heater Error Codes
- Error Code 5F
Error code 5F on a Hayward pool heater typically indicates a problem with the water pressure switch. This error can occur if there is low water flow or a blockage in the water circulation system. It’s essential to check the filter, pump, and valves for any obstructions or clogs.
- Error Code IF
When you see error code IF on your Hayward pool heater, it signifies a problem with the ignition or flame sensing circuit. This error can occur if the igniter fails to ignite the gas or if the flame sensor does not detect a flame. Inspect the igniter and flame sensor for any signs of damage or malfunction.
