Bradford White Water Heater Error Code No LED

No LED means the gas control valve is not receiving power and the pilot light is not lit. Without an active pilot flame, the thermocouple or thermopile produces no voltage to energize the gas control, so the status LED stays dark and both the pilot and main burners remain off. This condition causes the water heater to stop heating entirely.

The No LED condition itself is not a hazardous failure. It means the heater has safely shut down because no pilot flame was detected, which prevents unburned gas from being released through the main burner. You should still check for any smell of gas near the unit before attempting to relight the pilot, and if you detect a strong gas odor, leave the area and contact your gas utility before proceeding.

If the pilot simply needs to be relit, there is no parts cost. Replacing a pilot assembly typically runs in the range of $20 to $80 for parts, plus labor if a technician performs the work. A gas control valve replacement is more involved and parts alone generally range from $100 to $300 depending on the model, with professional labor adding to the total cost.

Start by relighting the pilot following the step-by-step instructions printed on the water heater label. If the pilot lights but goes out when you release the button, the pilot assembly including the thermocouple or thermopile likely needs to be replaced. If the pilot will not light at all after the assembly is replaced, the gas control valve itself must be replaced.

There is no electronic reset that will restore operation when the LED is completely off, because the gas control has no power to reset. The condition can only be cleared by successfully relighting the pilot, which restores thermoelectric voltage to the gas control and allows the LED to activate. If the pilot cannot be kept lit, the underlying component failure must be corrected first.
