LG Washer Error Code 3C

The 3C code on an LG washer indicates a motor driving error or hall sensor error. It means the control board is unable to properly communicate with or control the direct drive motor. Causes range from loose electrical connectors to internal motor damage. The first step is to check whether the PCB connector terminal is connected and the motor spinnet is properly engaged.

No, you should not continue running the washer while the 3C error is active. This code indicates the motor drive system is not functioning correctly, and operating the machine in this condition could worsen the underlying fault or create a safety hazard. Power the unit off and diagnose the issue before attempting another wash cycle.

Repair costs vary widely depending on the cause. If only a connector needs to be reseated, costs may be limited to a service call fee, typically in the range of $75 to $150. If the DD motor or IPM needs to be replaced, total repair costs including parts and labor can range from $200 to $450 or more depending on the model and service provider.

Some causes of the 3C error are DIY-friendly, such as reseating a loose connector at the PCB, motor, or hall sensor terminal. If the issue involves a damaged motor coil, a faulty IPM, or a failed DD motor, those repairs are more complex and typically require a trained technician. Always disconnect power before inspecting any internal wiring or components.

A power reset by unplugging the washer for a few minutes may temporarily clear the 3C code, but the error will return if the underlying cause is not addressed. If the code comes back after a reset, a physical inspection of the motor connections, hall sensor terminal, and motor components is necessary to find and fix the root cause.
