My LG washer will run through a normal wash cycle but will not drain. Drain hose is clear, drain filter is clear, and drain hose to utility sink is clear. The wash cycle will stop with an OE code with 12 minutes remaining (which is the spin and rinse cycle). I can get the washer to spin the clothes out on a separate setting but the water is not sent through the hose to the utility sink. Rather, I have to manually do it by utilizing the drain hose at the bottom of the washer. Please advise. Thinking drain pump
