What does error code 110 mean on a Bradford White water heater?
Error code 110 indicates an ignition failure lockout condition where the burner fails to light or maintain a stable flame.
When your water heater control board detects this fault, it shuts down gas flow for safety and displays ‘Service Needed’ alongside code 110. Meaning can vary slightly across specific electronic ignition model lines, so check your owner manual to confirm exact specifications.
- The control board initiates a call for heat and opens the gas valve.
- An electronic spark attempts to ignite the incoming gas mixture.
- The flame sensor fails to detect a proper flame signal within the safety window.
- The system locks out operation and flashes error code 110 on the digital display.
- Hot water production stops completely until the error is cleared or resolved.
Why does error code 110 happen on your water heater?
Common causes include interrupted gas supply, a dirty flame sensor, blocked venting, or a faulty electronic ignition component.
Ignition lockouts are protective responses triggered when combustion conditions are unsafe or unstable. Pinpointing the root cause requires evaluating your gas supply, electrical connections, and intake or exhaust pathways.
- Interrupted or low gas supply pressure preventing successful burner ignition.
- Corroded or soot-covered flame sensor rod unable to read the burner flame.
- Blocked air intake or exhaust venting restricting proper combustion airflow.
- Faulty electronic control module or worn internal wiring harnesses.
- Defective gas control valve failing to open properly during startup.
How can you perform a safe reset for error code 110?
Perform a soft reset using the power button or circuit breaker to clear temporary electronic lockouts.
Always ensure your hands are dry and safety guidelines are respected before touching any switches or panels. If the error immediately returns, do not continue resetting the unit.
- Locate the power switch on the water heater control panel and turn it off.
- Turn off the dedicated circuit breaker supplying power to the water heater.
- Wait at least 60 seconds to allow the internal electronic components to fully discharge.
- Turn the circuit breaker and control panel switch back to the ON position.
- Observe the digital display to verify if error code 110 disappears during startup.
What are the next troubleshooting steps if a reset fails?
Inspect external intake and exhaust vents for physical obstructions, blockages, or severe weather buildup.
If simple power cycling does not clear error code 110, you can check accessible venting components. Never disassemble gas-carrying lines or internal combustion chambers yourself.
- Turn off the power switch and breaker before inspecting any appliance components.
- Inspect the exterior termination vents outside your home for leaves, nests, or ice.
- Check that intake and exhaust pipes are securely connected and free of cracks.
- Restore power to test if clean airflow resolves the ignition lockout condition.
- Stop immediately and call a professional if the burner still refuses to ignite.
Which fix matches your specific ignition symptom?
Match your immediate symptom to the corresponding likely cause and recommended first-response action.
Different failure modes require distinct approaches ranging from basic power resets to professional component replacement.
| Symptom | Likely cause / fix |
|---|---|
| Instant lockout after reset | Blocked vent or gas supply issue; check external exhaust. |
| Clicks repeatedly, then errors | Igniter spark failure; professional inspection needed. |
| Works briefly then stops | Intermittent gas pressure drop; contact gas utility. |
| No display or power at all | Blown fuse or tripped breaker; check home electrical panel. |
When should you stop troubleshooting and call a technician?
Stop immediately and call a licensed professional if you smell gas, experience persistent lockouts, or need internal repairs.
Gas appliances present severe safety risks including carbon monoxide leaks and fire hazards. Component-level diagnostics involving gas valves or electrical control boards require professional certification.
- You detect any smell of natural gas or propane near the appliance.
- Error code 110 returns instantly every time you attempt a system reset.
- The repair involves opening the sealed combustion chamber or gas valve.
- You notice visible scorching, melted wiring, or damaged electrical components.
- Local regulations require licensed contractor service for gas appliance repairs.
What information should you have ready before calling for service?
Gather your exact water heater model number, serial number, warranty status, and a history of tried troubleshooting steps.
Providing precise details to your technician or manufacturer support line speeds up diagnosis and ensures they bring the correct replacement parts.
- Locate the rating plate label on the side of the water heater tank.
- Write down the exact model number and serial number string.
- Note the exact error code number displayed on the control board screen.
- Document whether you tried a power reset or inspected exterior venting.
- Check your purchase paperwork to see if the unit is still covered under warranty.
How can you keep error code 110 from coming back?
Schedule routine annual maintenance, keep exterior intake vents clear, and protect your electrical supply from surges.
Preventative care minimizes unexpected breakdowns and extends the operating lifespan of your water heater. Regular oversight catches minor environmental restrictions before they trigger a lockout.
- Schedule an annual professional tune-up and safety inspection every year.
- Inspect outdoor intake and exhaust terminals monthly for seasonal debris.
- Keep the area surrounding the water heater clear of dust, boxes, and lint.
- Install a surge protector to shield sensitive electronic control boards from power spikes.
- Review your owner manual guidelines for seasonal home maintenance checklists.
Frequently Asked Questions
Can I clean the flame sensor myself on a Bradford White water heater?
Cleaning internal flame sensors requires accessing the sealed combustion chamber and gas train. Because improper reassembly can result in dangerous gas leaks, this task should always be left to a licensed professional technician.
What should I do if error code 110 happens only during stormy or windy weather?
High winds can create exterior pressure fluctuations that disrupt proper drafting and trigger ignition lockouts. If the error clears automatically after weather conditions improve, your outdoor vent terminal may need a protective wind hood installed by a professional.
Does error code 110 mean my water heater gas valve is completely broken?
Not necessarily. While a defective gas valve can cause ignition failure, code 110 more frequently points to external issues like low gas supply pressure, blocked venting, or dirty sensors preventing normal burner ignition.
Is it safe to keep resetting error code 110 repeatedly?
No, repeatedly resetting an appliance that continues to fail is unsafe. If the unit locks out more than once, it indicates an underlying mechanical or venting problem that requires inspection rather than temporary manual resets.
Will a power outage or voltage drop trigger error code 110?
Yes, severe voltage fluctuations or sudden power interruptions can disrupt the electronic ignition sequence. Ensuring your water heater is plugged into a stable power source or dedicated circuit helps prevent erratic electronic behavior.
Bottom Line
Start by performing a safe power reset of your water heater control panel and circuit breaker. If error code 110 persists immediately, stop troubleshooting and contact a licensed service professional.
