🛠️ Common Hayward Error Code Guide for Maple & Woodbridge

Hayward FDN heater displays an IF code; replaced worn silicon nitride igniter in Maple.

If your Hayward heater stops running, the digital display provides a two-letter diagnostic code. While these codes point to a safety circuit, they require a professional diagnosis to pinpoint the exact failure.

LO (Limit String Open): The most frequent signal on FDN and ED2 models. It indicates a safety switch—like the water pressure switch or high-limit—has detected an unsafe condition. We test the "limit string" to find the specific fault.

IF (Ignition Failure): The heater failed to light after three attempts. In Maple, this is often a worn Silicon Nitride igniter in the FDN or a dirty Spark Electrode in the ED2.

AO (Blower Vacuum Switch Open): Specific to the FDN model. It means the combustion blower is running, but the vacuum switch isn't closing, often due to a blocked internal vent or a failing blower motor.

If the smell of Gas is detected, but the burner hasn't lit within the safety window. Shut off gas and call us.

❓ Frequently Asked Questions: Maple, Woodbridge & Kleinburg

Why does my Hayward display show "LO" in Woodbridge?

The LO (Limit Open) code is the most frequent call we get from Weston Downs and Pine Valley. While it often indicates a flow restriction—like a dirty filter or clogged skimmer—it can also be a failed high-limit switch or a faulty water pressure switch.

My Kleinburg ED2 is sparking, but the burner won't ignite.What’s wrong?

Since the ED2 uses Direct Spark Ignition (DSI), the "clicking" you hear is the electrode trying to light the gas. If it won't fire, we often find that the burner orifices are clogged by debris—a common occurrence in the wooded areas of Kleinburg and Stegman’s Mill.

Does the hard water in Maple affect how my heater runs?

Absolutely. In Vellore Village and Discovery, mineral deposits can form a "crust" on the Hayward thermistor (temperature sensor). This causes the sensor to read the water temperature incorrectly, meaning your heater might shut off before the pool is actually warm.

My FDN heater is flashing "AO." Is the blower motor broken?

AO (Blower Vacuum Switch Open) code means the blower is spinning, but the safety switch isn't closing. While it can be a failing blower motor, in Sonoma Heights we often find it’s a pinched vacuum tube or a blockage in the internal venting.

Why You Shouldn't Clear Codes Yourself

While some codes like LO can be resolved by cleaning your pool filter, codes involving IF, AC, or bD deal directly with the gas combustion process. As TSSA-certified gas technicians, we ensure that "Ignition Failures" aren't caused by dangerous gas leaks or blocked heat exchangers.
