How to fix LG washer error code OE (safe owner checks)

Safety first: disconnect power before you remove any panel or reach into the sump or drum. Do not touch wiring, the control board or the motor. If you see water near electrical parts, stop and call a technician. These steps are based on LG's published guidance [1], rewritten for clarity.

Check the drain hose. Make sure the hose behind the washer isn't kinked or clogged, then run a spin cycle.
Test the pump. Run Spin Only on High and listen for the pump humming in the first 15 seconds.
Clean the pump filter. If the pump hums, drain residual water and clean the drain pump filter (see your manual). Refit the drain-tube cap securely.
Run Tub Clean. Run Tub Clean and use less detergent; excess suds can cause it.
