How to Fix Bradford White Code F2
- Step 1: Check that the main water supply valve to the water heater is fully open.

What does F2 mean?
The F2 error code on your Bradford White tankless water heater indicates a 'Dry Fire Protection' lockout. This safety feature is triggered when the unit detects the burner is firing, but water flow is insufficient to cool it. Basically, the heater is getting too hot, which can damage the heat exchanger and other components. This is a protective measure to prevent serious damage. It's important to address this issue promptly to avoid further problems and ensure the longevity of your water heater. The unit will likely require a reset after the issue is resolved.
