Bradford White gas water heater status light: 2 quick flashes (a strobe), then a pause
No fault: the thermostat is calling for heat and the water heater is operating normally. Not a fault.
If you smell gas
Stop: do not relight or troubleshoot anything. Bradford White’s own words (first page of both Installation and Operation Manuals, 238-51007-00R and the Ultra Low NOx 238-53393-00K):
- DO NOT try to light any appliance.
- DO NOT touch any electrical switch.
- DO NOT use any phone in your building.
- Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.
- If you cannot reach your gas supplier, call the fire department.
Calling from a neighbor’s phone means leaving the building first.
What you see: two quick flashes, then a pause, repeating. Applies to: Bradford White residential gas-fired tank water heaters with the ICON System electronic gas control.
