LG Washer Error Code AUTO OFF

The AUTO OFF error means the auto off relay circuit is not functioning correctly. LG washers display this code when the control board detects a problem with the relay responsible for automatic shutoff. The most common cause is a bad connection at the BLUE 1-pin connector that links this circuit to the PWB ASM. If the connector is secure and undamaged, the PWB ASM itself may need to be replaced.

A reset may temporarily clear the code, but if the underlying connector or board fault is not corrected, the error will return. Unplugging the washer for a few minutes and plugging it back in can confirm whether the fault is intermittent, but a proper repair requires physically inspecting and correcting the connector contact or replacing the PWB ASM.

If the issue is simply a loose or corroded connector, the repair may cost little to nothing beyond a service call fee, typically in the range of $75 to $150. If the PWB ASM needs to be replaced, parts and labor combined generally range from $200 to $450 depending on the specific model and local labor rates. Getting a diagnostic from a qualified technician before ordering parts is advisable.

In many cases, the fix is straightforward. Start by unplugging the washer and locating the BLUE 1-pin connector on the PWB ASM, then reseat it firmly and inspect it for damage or corrosion. If the connector looks good and the error returns after restoring power, the repair will require replacing the PWB ASM, which is a more involved job that many DIYers can handle with the right guidance but may warrant a technician.

It is not recommended to continue using the washer while this error is active. The auto off relay is responsible for controlled shutoff functions, and a failure in this circuit could mean the washer does not shut off properly at the end of a cycle. Until the fault is diagnosed and corrected, continued use could pose a safety risk or lead to additional component damage.
