Every other load we have OE coming up, also the drowm will not spin

I Had this problem with my washer and fixed it by running dishwasher & wash machine cleaner through it I purchased at walmart. start a cycle with the cleaner in it then pause the washer after 2 to 3 minutes and let set for 4 to 5 hours then restart and let the cycle finish . then repeat 2 or 3 times after 2 months the error still has not returned.

LG washing machine error code - OE

The LG error code OE simply means "the pump is blocked". Presumably the water isn't being emptied properly. 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 or somewhere else in the system etc
