LG Washer Error Code BC

The BC code on an LG washer signals a switch check error, meaning the control system has detected a button that has been continuously pressed for more than 30 seconds. This can result from a stuck or jammed button, a deformed control panel, or sub PBA mounting screws that are fastened too tightly. The washer halts operation until the condition is resolved.

The washer will typically stop running when the BC code is active, so continued use is not possible until the fault is cleared. You should not attempt to force a cycle while the error is present, as a stuck button could cause the machine to behave unpredictably. Address the underlying cause before resuming normal operation.

If the fix is simply loosening over-tightened sub PBA screws or freeing a stuck button, there may be no parts cost at all, and a service call would typically range from around $75 to $150 for labor. If the control panel or sub PBA needs replacement, parts and labor combined can range from roughly $150 to $400 or more depending on the model and service provider.

Start by pressing each button on the control panel to confirm they all spring back freely and none are physically stuck. Inspect the panel for any visible warping or damage. If the panel looks fine, open the unit and check whether the sub PBA screws are over-tightened, as loosening them slightly can relieve pressure on the tact switches and clear the error. If a tact switch or the control panel itself is damaged, the affected component will need to be replaced.

A power reset may temporarily clear the BC code from the display, but if the root cause is still present, such as a stuck button, warped panel, or over-tightened sub PBA screw, the code will return. A reset is useful for confirming whether the issue is intermittent, but it does not fix the underlying hardware problem.
