In other words, it's not draining. Master john63 illumines us on how to repair this. Let's listen in:
Remove both hoses from the DRAIN MOTOR/PUMP ASSY.
Inspect the hoses for obstruction (such as---a coin or large button).
NOTE: I usually place a dry towel over the *drain outlet* hose (the hose that goes from the washer-to-the-drain) and poke a hole in the towel---then I blow air through the drain hose. If the water in the hose clears/drains out---the hose is likely not obstructed with debris/foreign object(s).
Inspect the IMPELLER (looks like an airplane propeller) on the DRAIN MOTOR for debris preventing/obstructing the IMPELLER from spinning (such as a small nail). Examine the IMPELLER *blades* (4 blades) for damage. If 2 or more of the *blades* are missing/broken---water will not drain sufficiently (or at all). In some cases---the IMPELLER appears normal---but has actually become separated from the DRAIN MOTOR shaft and is not spinning when the motor is energized during the DRAIN CYLE.
