How to Fix the Hayward Heater IF Code [SOLVED]

Occasionally, I’ve encountered the IF code when asked to come out to a client’s house to troubleshoot their Hayward pool heater issues. This error code indicates an ignition failure, preventing the heater from starting. Ignition failures can be caused by various issues, ranging from minor problems to major malfunctions. In this article, I’ll cover the most common causes of the Hayward heater IF code and provide step-by-step instructions on how I fixed this issue.

Understanding the Hayward Heater IF Code

Before we dive into the troubleshooting steps, let’s first understand what the Hayward heater IF code means. The IF code appears on the heater display when the ignition sequence fails to complete. The heater attempts to light the burner three times before displaying the IF code and shutting down. The code protects the heater from damage caused by a gas buildup or other ignition-related problems.

Common Causes of the Hayward Heater IF Code

There are several reasons your Hayward heater may be displaying the IF code. Here are the most common causes:

1. Gas supply issues: If your heater isn’t receiving a sufficient supply of gas, it won’t be able to ignite the burner. Check the gas valve and make sure it’s fully open. It would be best to verify that the gas line is clear of debris or blockages.
2. Pilot light problems: If the pilot light isn’t lit, the heater won’t be able to ignite the burner. Check the pilot light assembly and ensure it’s clean and debris-free. It would be best to verify that the pilot light’s gas supply is working properly.
3. Igniter issues: The igniter is responsible for lighting the burner. If it’s not functioning correctly, the heater won’t be able to start. Check the igniter for signs of wear or damage. You should also ensure that the igniter’s wires to the control board are properly connected.
4. Control board problems: The control board is responsible for regulating the various components of the heater. The heater may display the IF code if it’s not working correctly. Check the control board for signs of damage or wear. You should also ensure that all connections to the control board are properly connected.
