Bradford White Water Heater Error Code 64

Error code 64 on a Bradford White water heater indicates an electronics failure within the unit's control system. The onboard diagnostics have detected a condition in the control board or its circuitry that prevents normal operation. This is an internal hardware-level fault rather than a sensor or input error. The water heater will typically suspend normal heating operation until the issue is resolved.

A power reset by turning off the unit and restoring power after a few minutes may temporarily clear the code if the fault was caused by a minor firmware or memory glitch. However, if the underlying electronics have been physically damaged, the code 64 will return shortly after the reset. A reset that does not hold is a strong indicator that board replacement is needed.

Repair costs for an electronics failure vary depending on whether the fix involves reseating connections or replacing the full control board. A control board replacement typically falls in the range of $200 to $500 or more including parts and labor, depending on the specific model and local labor rates. If the unit is older and out of warranty, it may be worth comparing repair costs against the price of a new water heater before proceeding.

Some basic steps such as inspecting wiring connections and performing a power reset are within reach for a knowledgeable DIYer. However, if the control board itself has failed, replacing it requires working with gas appliance components and electrical wiring, which is best handled by a licensed technician. Attempting control board replacement without proper experience could create safety risks or void any remaining warranty.

When error code 64 is active, the water heater has typically suspended normal operation as a precaution, meaning it may not be heating water at all. You should not attempt to bypass the fault or force the unit to run while this code is present. Leave the unit in its faulted state and contact a qualified technician to diagnose and correct the electronics failure before resuming use.
