What does oe mean on my washing machine display

OE means uneven load.
If you can open door, put a dry towel in with the washing and try spinning again ...

There may be a few different reasons why the OE error code can display on your washing machine. Is it the LG washer getting the OE error code?

An Error code OE on The LG washing machines simply means the pump is blocked.
Presumably the water isn't being emptied properly you might have something blocking the pump.
As with all error codes it is possible that there is a cause other than the exact description in the error code explanation but basically this error means as far as the washing machine is concerned it thinks the water isn't pumping out.
A pump, or filter blockage is the most common cause but it could be caused by other faults such as a faulty pump, or even a blockage in the drain hose near the sink waste or somewhere else in the system etc.

check pump for blockage

The LG error code OE simply means "the pump is blocked".
A pump, or filter blockage is the most common cause but it could be caused by other faults such as a faulty pump, or even a blockage in the drain.

An OE error presents if the washing machine has not successfully drained the water in ten minutes. However, the OE error code does not always mean that the washer requires a service call. If periodic maintenance has not been performed on the washer, there are a few simple steps to take before calling for service. Clear the filter located on the bottom left on the face of the machine. You will find a access panel located there that you need to open. Happy Holidays The FixYa Team

OE error is noyhing but an Outlet Error.. OE simply means “the pump is blocked”. Clean and straighten the drain hose / clean the drain filter. Check the hoses (drain hose) and the pump filter but if it didn't cure the problem then turn the thing upside down and strip the pump out of it check if anything is caught in the impellor.. if so remove it and everything will be fine..
