Wont drain LG FRONT LOAD WASHER MODEL# WM2496HSM HAS AN ''OE'' CODE AND DOESNT DRAIN. no jambs or clogs

I would guess that the impeller has come off the pump motor shaft. You can disassemble and push it back on, but it will come off again. I don't know if some type of adhesive would work, but I just replace the pump motor.
Drain water from small drain hose (or by removing filter) Remove the screw in the plastic recess by the filter, then use a putty knife on the left or right side to pop out the recess. Remove two more screws holding pump body to front frame of washer. Pull washer about 18 inches away from wall and tilt it back to lean against wall. There is a plastic locking tab holding the pump body to the plastic washer base, but don't worry if you break that, as the screws (removed earlier) will hold the pump back on just fine. Pump motor is held onto pump body with three more screws. Replace pump motor with a new one and reassemble. On a difficulty scale of 1 -10, this one might rate a 3.5 or a 4. Not too bad.
