LG Washer Error Code 9E

The 9E code means the washer detected an abnormal supply voltage condition. Specifically, the incoming AC voltage was measured above 275 volts or below 150 volts. The machine stops operation to prevent damage to its electronics and motor. The problem is most often related to household electrical supply rather than a failed part inside the washer.

The 9E code is actually a protective feature, not a sign of immediate danger. The washer detected unsafe voltage and shut itself down to avoid damage to its components. However, the underlying cause, such as a voltage spike or faulty wiring, can pose a risk to other appliances or create a fire hazard. It is worth having your electrical supply inspected if the error appears repeatedly.

If the cause is a temporary utility fluctuation, there is no repair cost at all. Replacing a faulty wall outlet typically runs between $75 and $200 including labor. Electrical panel wiring corrections by a licensed electrician can range from $150 to $500 or more depending on the complexity. If the control board's voltage sensing circuit is at fault, board replacement can cost between $200 and $500 for parts and labor.

In many cases, yes. Start by pressing the START key to attempt to clear the error. If it clears and does not return, the voltage issue was likely a temporary utility fluctuation. If the error keeps coming back, check that the washer is plugged directly into a wall outlet on a dedicated circuit, and use a multimeter to verify the outlet is delivering normal voltage. Wiring problems at the panel or outlet should be handled by a licensed electrician.

Pressing the START key can cancel the error if the voltage has returned to a safe level. If the supply voltage is still out of range when you attempt to reset, the error will continue to display. A power cycle or reset will not permanently resolve the issue if the underlying electrical problem remains. The voltage at the outlet must be within the acceptable range before the washer will operate normally.
