Bleach dispenser in a new LG washer is not flushing completely
<<<I just bought a LG WM2101 and the bleach tray doesn't flush completely>>>
A commonly asked question.
In nearly all cases---the BLEACH did in fact---dispense into the tub at the appropriate time during the cycle.
In nearly all front loading washers with a *drawer* type dispenser assembly---a small amount of water remains in the dispenser compartments (Prewash/Main Wash/Bleach Liquid/Fab Softener).
To verify that the bleach dispenser is indeed functioning correctly...
After a cycle ends---open the drawer and "dip" your finger into the bleach dispenser.
Smell the liquid--if a *heavy* bleach odor is present then the dispenser failed to function.
If the smell has a *faint* bleach odor---normal.
