What is the most common LG washer error?

The single most frequent error code displayed on LG front-load and top-load residential washing machines is the "OE" error code, which indicates that the appliance is unable to drain wastewater properly from the inner drum. Over months of regular use, coins, lint, hair pins, and small fabric items slip past the drum baffle and accumulate inside the lower drain pump filter, blocking the impeller and preventing wastewater from evacuating. When the electronic control board detects that water remains after a drain cycle, it aborts high-speed spinning and flashes "OE." You can troubleshoot drainage failures easily by opening the bottom service panel. You can verify that your corrective action is successful when unscrewing the pump filter plug, clearing trapped debris, and running a manual drain program allows the washing machine to empty wastewater rapidly without displaying the error code again.
