LG Washer Error Code PS

The PS code on an LG electric dryer indicates a dryer power supply wiring problem, not a washer issue. It appears when 240 volts is incorrectly supplied to the main PCB due to improper power cord wiring at the terminal block. The dryer shuts down automatically to protect the control board from damage. This code is specific to LG electric dryers and is a protective response to a detected wiring fault.

Yes, the PS error indicates a real wiring fault involving 240V power, which is a serious safety issue if left uncorrected. The dryer's control system shuts down specifically to prevent damage to the PCB, but the underlying wiring problem could also pose a risk of electrical damage or fire if the unit were somehow operated in that state. Do not attempt to bypass the error or force the dryer to run until the wiring has been inspected and corrected by someone qualified to work with high-voltage circuits.

If the fix only requires correcting the wiring at the terminal block without replacing any parts, a service call to have a technician inspect and rewire the connection typically costs in the range of $75 to $150 depending on your location. If a new power cord is needed, the part itself generally costs between $15 and $40, with labor added on top. Costs can be higher if there is damage to the terminal block itself or if additional diagnostic work is required.

Start by disconnecting power to the dryer completely before touching any wiring. Then inspect the power cord connections at the terminal block on the back of the dryer, comparing each wire position against the wiring diagram on the unit. Correct any miswired or loose connections, restore power, and check whether the code clears. If you are not comfortable working with 240V wiring, contact a licensed electrician or appliance technician.

No, resetting the dryer will not permanently clear the PS error if the wiring problem has not been fixed. Because the code is triggered each time the unit detects 240V at the PCB due to incorrect wiring, the error will return immediately when power is restored. The underlying power cord or terminal block wiring issue must be corrected first before the dryer will operate normally.
