LG WashTower WKEX300HBA washer section will not drain or stops with water inside

The checks in more detail

Then the drain pump filter. On the WashTower it is behind a small cover at the lower front of the washer. Put towels and a shallow tray down, switch off and unplug the tower, open the cover, drain the water from the small hose and unscrew the filter slowly, then clean out coins, hair and lint. Look inside for anything stuck in the pump impeller. Refit the filter firmly. Run a Drain and Spin to test. The dryer vents separately and does not affect the washer's drain, but the washer and dryer share the control, so a control fault may affect both. Too many suds from excess detergent can cause a drain error, so use the right amount of HE detergent and run a rinse.

If the pump hums and no water moves, the pump may have failed, a repair that needs a technician and requires moving the tower. A washer that makes no sound at all may have a control or power fault. Because the unit is heavy and tall, do not tip it. Clean the filter every few months, and run the Tub Clean cycle monthly. Keep the model and serial numbers from the label, and contact LG if the washer still will not drain after clearing the hose and the filter. On the WashTower, the washer sits at the bottom and its drain hose and power cord run behind the whole tower, so a kink is hard to see from the front.

Pull the tower out with a helper and check the hose along its length, and look at the wall box for a clog. The WashTower has a single center control panel that you operate for both washer and dryer, and after a drain error, the panel may continue to show the code until you press Power to switch the unit off and on. The pump filter at the lower front of the washer is the most common blockage; clean it on a schedule to avoid repeats. If the washer drains a little and then stops, run Drain and Spin on its own and listen for the pump, which has a clear whirr when it works and a hum when it is blocked.
