LG Washer Error Code PS — Power Supply Issue
What this means
The PS error code indicates the washer is detecting an issue with its power supply. This can be caused by using a power strip or extension cord instead of a direct wall outlet, a loose wall outlet, or voltage fluctuations in your home electrical system. The washer requires a stable, dedicated 120V circuit.
Step-by-step fix
3 stepsPlug directly into a wall outlet
If the washer is connected through a power strip, extension cord, or surge protector, remove it and plug the washer's power cord directly into a grounded wall outlet.
LG recommends a dedicated 120V, 15-amp circuit for their washers.
Check the outlet
Ensure the wall outlet is not loose. Plug another appliance into the same outlet to verify it provides consistent power.
Power-cycle the washer
Unplug the washer for 60 seconds, then plug it back in and start a cycle.
When to call a professional
If the outlet is loose, damaged, or the voltage is inconsistent, contact a licensed electrician to inspect and repair the circuit.
