    Leaks, rusty water, frequent pilot light issues, or reduced hot water output can indicate it’s time to replace the unit, not just repair it.

    Yes! A. O. Smith has high-efficiency tank and tankless models designed to handle colder incoming water temperatures.

    This usually means sediment has built up at the bottom of the tank, which is a common issue in Calgary due to mineral-heavy water. A flush often solves it.

    Once a year is ideal, but with Calgary’s hard water, twice a year can significantly extend the unit’s lifespan.

    Typically every 3 to 5 years, but Calgary’s mineral content may require more frequent checks.

    An anode rod is a long metal rod inside your water heater tank that protects the tank from rusting. It’s usually made of magnesium, aluminum, or a zinc/aluminum blend.

    Gas water heaters heat water faster and recover more quickly, which is helpful in Calgary homes where incoming water is colder in winter. They typically cost more upfront but are often cheaper to operate if natural gas rates are reasonable.

    Electric heaters are usually more affordable to install and maintain, but they heat water more slowly and can struggle to keep up during high-demand times. They’re a good option for smaller households or homes without gas lines.

    Regular flushing, proper temperature settings, fixing leaks, insulating pipes, and upgrading to high-efficiency or tankless units all help!

    Yes, options include raising the temperature safely, adding a mixing valve, or installing a second tank or tankless booster.

    It’s usually fine, but always follow manufacturer guidelines. Setting it too high increases scalding and energy risks.

    An annual checkup is recommended. In areas with hard water, flushing the tank more frequently helps prevent sediment buildup.

    AO Smith Water Heater Error Codes

    Meaning:

    The thermostat isn’t reading or responding correctly, so the heater can’t control the temperature properly.

    Troubleshooting information:

    • Check for loose or damaged wiring at the thermostat and control board
    • Reset the unit by turning power off for 30 seconds, then back on
    • If the wiring and reset don’t help, the thermostat may need replacement. Call a technician to test and swap it safely.

    Meaning:

    The flame sensor isn’t detecting the burner flame, so the system won’t allow the burner to run.

    Troubleshooting information:

    • Turn the unit off, open the access panel, and inspect the sensor for soot or buildup.
    • Carefully clean the sensor with fine sandpaper or a soft cloth (power off first).

    If cleaning doesn’t fix it, the sensor may be failing and should be replaced by a pro. For any gas work, contact a certified gasfitter at One Stop HVAC.

    Meaning:

    The system attempted to ignite the burner but couldn’t. No flame was established.

    Troubleshooting information:

    • Confirm the gas supply is on and other gas appliances in the home are working.
    • Check for obvious blockages in vents or flues and make sure the area is free of debris.
    • If the igniter or pilot looks damaged or the gas line seems restricted, call a licensed technician to inspect and repair.

    Meaning:

    The unit detected dangerously high temperatures and shut down to protect itself and your home.

    Troubleshooting information:

    • Power the unit down and let it cool before inspecting.
    • Look for stuck relays, tripped safety switches, or incorrect thermostat settings.

    Don’t attempt to bypass safety features. This requires a qualified service tech to diagnose and fix wiring, controls, or faulty components.

    Meaning:

    Components aren’t talking to each other properly, typically the control board and other controls or sensors.

    Troubleshooting information:

    • Inspect wiring harnesses and connectors for loose pins, corrosion, or damage.
    • Perform a system power cycle (off for 30 seconds) to see if the fault clears.

    If it returns, the control board or a sensor likely needs testing or replacement by a technician.

    Meaning:

    The tank has exceeded its normal water level, often due to a faulty valve or pressure device.

    Troubleshooting information:

    • Check for water around the unit and verify the pressure relief valve isn’t stuck open or leaking.
    • Inspect inlet valves for proper operation. Don’t force valves closed.
    • Shut off the water supply and call a tech if you see ongoing overfilling or leaks. This can lead to serious damage if ignored.
