7 Flashes
Bradford White Water Heater
Severity:What Does This Error Mean?
7 flashes is a hard lockout — the unit attempted ignition, failed, and will not auto-reset. Verify gas supply and vent clearance, then perform a full manual reset using the gas valve procedure.
Affected Models
- Bradford White Defender Safety System
- Bradford White M-Series Gas
- Bradford White RG Series Gas Tank
- Bradford White AeroTherm
Common Causes
- Gas supply interrupted or shutoff valve partially closed
- Blocked or frozen exhaust vent
- Failed igniter not producing a spark
- Flame sensor coated in deposits and unable to detect flame
- Empty propane tank on LP models
How to Fix It
-
Count the LED flashes to confirm 7.
The status light on Bradford White gas models is on the gas valve body or near the access panel. Count 7 rapid flashes followed by a pause to confirm hard lockout.
-
Check the gas supply.
Confirm the manual shutoff valve behind the unit is fully open. Check other gas appliances — if none have gas, the problem is at the meter or supply line.
-
Check the LP tank if applicable.
On propane models, an empty or nearly empty tank is one of the most common causes of 7 flashes. Refill before attempting a reset.
-
Check the vent exhaust outside.
Inspect the vent pipe terminal outside for debris, ice, or bird nests. A blocked vent prevents combustion and triggers hard lockout on Bradford White models.
-
Perform the manual reset procedure.
Turn the gas valve knob to OFF. Wait 5 minutes for any residual gas to clear. Then follow the pilot lighting instructions on the label inside the access panel. Hard lockout requires this full procedure — there is no single reset button.
When to Call a Professional
If 7 flashes returns after a successful reset and restart, the igniter, flame sensor, or gas valve requires professional inspection.
Frequently Asked Questions
Why does 7 flashes require manual reset when other codes auto-reset?
7 flashes is a hard lockout designed to prevent repeated failed ignition attempts that could accumulate unburned gas. Bradford White requires manual intervention to confirm someone has inspected the unit before it tries again.
My Bradford White lights then immediately shows 7 flashes — why?
Ignition followed immediately by 7 flashes means the flame sensor is not detecting the flame even though combustion occurred. The flame sensor likely needs cleaning or replacement.
