Bradford White Water Heater Error Code None

This condition indicates that the electronic control board on the Bradford White water heater is receiving no electrical power. It is not a fault code generated by the control itself, but rather the absence of any control activity due to a missing power supply. The cause is typically a power switch in the OFF position or an interruption in the 120V AC supply circuit.

When the control has no power, the water heater will not operate at all, so there is no active heating or ignition occurring. The unit is effectively off, which is not a safety hazard in itself. However, you should investigate the cause of the power interruption before restoring power to rule out any wiring issues or faults that may have tripped the breaker.

If the fix is simply turning on a switch or resetting a breaker, there is no cost. If a failed power switch needs replacement, parts and labor typically range from around $75 to $200 depending on the service provider and part availability. A control board replacement is more involved and can range from $200 to $500 or more, including parts and labor.

Start by checking that the power switch on or near the unit is set to ON. Next, go to your electrical panel and check whether the circuit breaker for the water heater has tripped. If the breaker is good and the switch is on, use a multimeter to verify 120V AC is present at the unit's power input terminals. If voltage is present but the control still does not respond, a faulty switch or control board may need to be replaced.

Yes, if a tripped breaker is the cause, resetting it will restore power to the control and the water heater should resume normal operation. If the breaker trips again shortly after being reset, there may be an underlying electrical fault in the circuit or the unit that requires further diagnosis before the breaker is reset again.
