Boiler displays E10 and will not start; may indicate fan or inducer failure.

Safety first: Turn off power and gas. The inducer is part of the combustion system; improper repair can lead to carbon monoxide hazards.

• Step 1 – Visual inspection: Remove the front panel and locate the inducer assembly. Check for obvious damage, loose mounting screws, or signs of water intrusion.
• Step 2 – Check for obstructions: With power OFF, spin the inducer wheel by hand if accessible. It should rotate freely without scraping. Remove any debris carefully.
• Step 3 – Inspect wiring: Verify that the inducer’s electrical connector is fully seated and that wires are not pinched or burned.
• Step 4 – Test operation: Restore power and call for heat. Listen for the inducer starting. If it hums but does not spin, or does not start at all, the motor is likely failed and must be replaced.
• Step 5 – Fan speed feedback (if applicable): On models with fan speed sensors, a failed sensor or control board can cause E10 even if the fan runs. This requires diagnostic tools and should be handled by a technician.

Note: Always replace the inducer with the exact Bradford White-specified assembly to ensure proper airflow and safety.
