⚠️ The water heater has shut down due to a potential dry-fire condition. This requires investigation and may indicate a problem that could damage the unit if left unaddressed.
How to Fix Bradford White Code F2

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.
