LG Washer Error Code 10

Error code 10 on an LG washer indicates a ball sensor error. It means the control system detected either a loose connector at the ball sensor or a ball sensor that has failed. This code only appears during QC Test Mode when the Start/Pause button is first pressed, so it is typically encountered by technicians running diagnostic checks rather than during a standard wash cycle.

Error code 10 only displays in QC Test Mode, not during normal operation, so your washer may still run regular cycles without triggering this code. However, if the ball sensor is faulty, the washer may lack full diagnostic capability. It is best to have the sensor inspected and repaired before relying on the machine for continued use.

If the fix is simply reseating a loose connector, there may be no parts cost involved, though a service call fee typically ranges from $75 to $150 depending on your area. If the ball sensor itself needs replacement, parts and labor combined generally range from $100 to $250. Costs can vary based on parts availability and local labor rates.

Start by locating the ball sensor and checking that its wiring harness connector is fully and firmly seated. If the connector is secure and the error persists, the ball sensor itself will need to be tested for proper function and replaced if faulty. Also inspect the wiring harness between the sensor and the control board for any visible damage.

Resetting the washer will not permanently clear error code 10 if the underlying hardware fault is still present. The code will reappear the next time QC Test Mode is initiated. The fault must be corrected by reseating the connector or replacing the ball sensor before the error will be resolved.
