Wiring issues

Loose, damaged, or disconnected wiring between the water level sensor and the main control board can disrupt communication, leading to the LG washer problem codes. Frayed or disconnected wires should be inspected and repaired promptly to avoid persistent errors.

Environmental factors

High humidity or exposure to moisture can interfere with the washer’s internal components, including the pressure sensor. Ensuring a dry and well-ventilated laundry area can help prevent this issue.

In some cases, the washer’s motherboard may be faulty, failing to process signals from the water level sensor correctly. If all other troubleshooting steps fail, a motherboard issue could be the root cause.
