LG Washer Error Code OVER FLOODING

The OVER FLOODING error on an LG washer indicates the machine has detected an overflooding condition during its QC diagnostic mode. It is most commonly caused by a disconnected or poorly connected ball pressure sensor connector, which leaves the control board unable to verify the water level. The inlet valve is also a suspected component when this error appears.

No, you should not run the washer with this error active. The error indicates the machine either cannot monitor its water level or has detected too much water entering the tub. Continuing to operate it risks actual water overflow and potential water damage to your home or the appliance itself.

If the fix is simply reseating a loose connector, there is no parts cost. If the ball pressure sensor needs replacement, parts typically range from $15 to $50 depending on the model. If the inlet valve is at fault, parts generally range from $25 to $75. Adding professional labor, total repair costs can range from $100 to $250 or more depending on your location and the technician's rates.

In many cases, yes. Start by checking the ball pressure sensor connector to make sure it is fully seated and free of corrosion. If the connector is secure and the error persists, the ball pressure sensor or inlet valve may need to be tested and replaced, which requires basic appliance repair skills and the appropriate replacement parts.

A reset may temporarily clear the error display, but it will not fix the underlying problem. If the ball pressure sensor connector is loose or the inlet valve is faulty, the error will return when the washer runs again. The root cause must be diagnosed and corrected for the error to stay cleared.
