LG Washer Error Code C3

C3 on an LG washer indicates a motor hall sensor fault. The hall sensor monitors rotor position inside the direct drive motor and reports movement data to the main control board. When that signal is missing or erroneous, the washer displays C3 and stops operation. Causes range from loose connectors and a displaced motor cover to a failed control board or motor.

No, you should not continue running the washer while C3 is active. The error indicates the control system cannot reliably monitor motor operation, which means the motor could behave unpredictably. Running the machine under these conditions risks further damage to the motor or control board.

Repair cost depends on which component is at fault. If the fix is simply reseating a connector or repositioning the motor cover, there may be no parts cost at all, with labor ranging from around 60 to 120 dollars if a technician is involved. Replacing the main PBA typically runs between 150 and 350 dollars in parts and labor, while a full DD motor replacement can range from 200 to 450 dollars or more depending on the model and service rates in your area.

Some C3 causes are DIY-accessible. Start by checking that all motor connector terminals are firmly seated and that the DD motor cover is properly in place, as these are the most common and easiest fixes. If connections and covers check out, the fault may lie with the main PBA or the DD motor itself, which typically requires more advanced repair skills and replacement parts.

A reset may temporarily clear the code, but C3 will return if the underlying problem is not resolved. Unplugging the washer for a few minutes and restarting can help confirm whether the fault is intermittent or persistent. If the code reappears immediately or consistently, a physical inspection of the motor connections, motor cover, and wiring is necessary.
