LG Washer Error Code E3

The E3 code on an LG washer signals a Motor Driving Error and Hall Sensor Error. It means the control board is receiving erroneous or no signals from the hall sensor in the direct drive motor, preventing the washer from operating the drum safely. The root cause can range from a loose wire connector to a failed motor or control board.

A reset may temporarily clear the display, but the E3 error will return if the underlying fault is not corrected. Unplugging the washer for a few minutes can reset the board, but if a connector is loose, the cover is misaligned, or a component has failed, the code will come back as soon as the machine attempts to run the motor again.

Repair costs vary depending on what component has failed. If the fix is simply reseating a connector or repositioning the motor cover, there may be no parts cost, just a service call fee ranging from around 75 to 150 dollars. Replacing a DD motor can cost between 150 and 350 dollars in parts and labor, while a main PBA replacement can range from 200 to 450 dollars depending on the model and local labor rates.

In many cases, yes. The first step is to unplug the washer and inspect all motor connector terminals for loose connections, corrosion, or displaced housings. If the DD motor cover is out of place, reseating it may clear the error. However, if the fault is traced to the DD motor or main PBA, those repairs typically require component replacement and some technical experience.

No, you should not attempt to run the washer while the E3 code is active. The error indicates the motor control system is not functioning correctly, and continued operation could worsen the fault or cause additional damage to the motor or control board. Leave the washer unplugged until the issue is diagnosed and resolved.
