If the washer is not draining here are the step involved to clean the drain pump.
-Unplug the washer
-Bail water out of washer
-Tip unit back
-Get towels (several)
Now that most of the water is out and the electricity is turned off you need to remove the drain pump.
Doing so will let water flow from the hoses onto the floor so be prepared.
On the bottom front right you will find the drain pump. Unplug the wires from the pump and depress the tab while twisting the pump out of place.
With the tab depressed twist the pump out of the lock position and it will fall out. Clean any foreign debris that is located inside the drain pump assembly and reassemble. With the drain motor clear the washer should start draining.
