If a Bradford White gas water heater has no hot water, first confirm whether the problem affects every hot-water outlet and whether the heater shows any normal operating indication through its intended viewing window or control display.

First determine whether every hot tap is cold or only one fixture, then identify whether the heater is gas, electric, tankless, or a heat-pump unit.
