LG Washer Error Code Auto Off Error

The Auto Off Error means the washer has detected a fault in the Auto Off relay circuit, which controls how the machine shuts down after a cycle. The error is caused either by a failed relay on the main control board (PWB ASM) or by a bad connection at the Blue (BL) 1-pin connector that links the relay circuit to the board. The washer stops operation and displays this error to alert you that the shutdown relay system is not functioning correctly.

It is not recommended to continue using the washer while this error is active. The Auto Off relay is part of the circuit that properly powers down the machine at the end of a cycle. A malfunction in this system could lead to components remaining energized when they should not be, creating a potential safety concern. Diagnose and resolve the fault before resuming normal use.

If the fix is simply reseating or cleaning the Blue 1-pin connector, your cost could be minimal, covering only your time or a basic service call fee ranging from $50 to $100. If the PWB ASM needs to be replaced, parts alone typically range from $100 to $300 depending on the specific model, with professional labor adding another $75 to $150 on top of that.

In many cases, yes. Start by unplugging the washer, locating the Blue 1-pin connector at the PWB ASM, and reseating it firmly to ensure good contact. Check the pin for corrosion and the housing for a damaged locking tab. If the connector is in good shape and the error returns, the PWB ASM will need to be replaced, which is a more involved repair that requires some technical comfort with appliance electronics.

A basic power reset by unplugging the washer for a few minutes may temporarily clear the error display, but the code will return if the underlying fault is not corrected. The error will continue to appear until either the Blue 1-pin connector is properly reseated and restored to good condition, or the PWB ASM is replaced.
