Boilers are essential for maintaining a comfortable and cozy home environment, especially during Ottawa’s chilly winters. However, when a boiler malfunctions, it often displays error codes that can be confusing for homeowners. Understanding these error codes can help you identify issues early and decide when to call in the professionals.
In this article, we’ll explore some of the most common boiler error codes, what they mean, and how AirZone HVAC Services can help you resolve them quickly and efficiently. We’ll also highlight the top-quality boiler brands we carry and how our Family Plans can save you money on maintenance and repairs.
Common Boiler Error Codes and What They Mean
Please note: Error codes can vary between different boiler brands and models. Always refer to your boiler’s user manual for codes specific to your unit.
Error Code E01 or F1 – Ignition Failure
Meaning: The boiler has failed to ignite after several attempts.
Possible Causes: Gas supply issues, faulty ignition electrode, or a defective gas valve.
What to Do: Check that your gas supply is on and functioning. Try resetting your boiler according to the manufacturer’s instructions. If the problem persists, contact AirZone HVAC Services for expert assistance.
Error Code E02 or F2 – Flame Loss
Meaning: The boiler detects that the flame has gone out during operation.
Possible Causes: Interrupted gas supply, faulty flame sensor, or issues with the burner.
What to Do: Confirm that there are no issues with your gas service. If the gas supply is fine, it’s time to call our team to inspect and repair your boiler safely.
Error Code E03 or F3 – Fan Fault
Meaning: The boiler’s fan is not functioning correctly, which can prevent safe operation.
Possible Causes: Fan motor failure, blocked flue or vent, or electrical connection issues.
What to Do: Do not attempt repairs yourself, as fan faults can be dangerous. Contact AirZone HVAC Services, and our certified technicians will safely resolve the issue.
Error Code E04 or F4 – High/Low Water Pressure
Meaning: The boiler’s water pressure is either too high or too low.
Possible Causes: Leaks in the system, recently bled radiators, or a faulty pressure relief valve.
What to Do: Check the pressure gauge; ideal pressure is typically around 1.5 bar. Follow your manual to increase or decrease pressure as needed. If you’re unsure, our technicians can help you adjust the pressure safely.
Error Code E05 or F5 – Overheating
Meaning: The boiler is overheating due to inadequate water flow or other issues.
Possible Causes: Pump failure, blocked or closed valves, or limescale buildup.
What to Do: Turn off the boiler to prevent further damage. Call us immediately—we’ll diagnose and fix the problem promptly.
