An LG WT6105CW top-load washer that will not drain leaves a tub of water and an unfinished cycle, and the cause is nearly always a kinked or blocked drain hose, a clogged pump or an object in the path, rather than a failed part. Begin with the hose at the back. The drain hose runs from the washer to a standpipe or sink, and it must not be kinked behind the machine, crushed or pushed too far into the standpipe, and the end must sit within the height range the manual gives, because a hose too low lets water siphon out and one too high stops it draining.
The checks in more detail
Pull the washer forward gently and look at the hose, straighten it and check that the standpipe is clear. Next look at the washer's own filters. A top-load washer has a lint filter in the drum or a drain pump that can catch a sock, a coin or a bra wire. If your model has a drain filter, check the manual for its place; many top-loaders need the access panel at the front or rear removed to reach the pump. Unplug the washer and take care, since water is in the tub;
bail out what you can into a bucket, then look for an object in the pump or the drain tube. Check the lid switch as well, since some washers will not enter drain and spin if the lid is not detected as closed; press the lid closed firmly and try again. A washer that drains slowly may have a clogged standpipe or a house drain that is backing up, so run the sink or check other drains. Overloading with a heavy load or too much soap can cause a failed drain, because the machine detects a problem and pauses; remove some clothes and run a drain and spin.
Make sure you are using HE detergent in the right amount. If an error code appears on the display, note it and look it up in the manual, as a drain error code points to the pump or the hose. The WT6105CW is an entry model with a simple control panel, so there is no app. If the pump hums but does not move water, it may have failed, and a replacement pump is a modest repair. Contact LG with the model and serial number if the washer still will not drain after clearing the hose and the pump.
