If the problem you are having is that your Whirlpool top load washer won't spin dry the clothes, follow this procedure to determine if the problem is a broken motor coupler.
Set the washer on the regular cycle, large load and let it fill. After the washer fills to the selected level, the motor should start and the agitator should start agitating.
If you hear the motor running, but the agitator doesn't move at all, do the following. Stop the washer and set the timer on the spin cycle and let it run.
If the washer motor runs and the washer empties the water from the tank, but it won't spin, that is an indication that the motor coupler is not turning the transmission at all.
The motor coupler is made of two pieces of plastic called fingers and a hard rubber piece that goes in between the two fingers. One of the fingers is attached to the motor and the other finger is attached to the transmission. The had rubber round piece goes between the two fingers. When one of the plastic fingers breaks, the motor is no longer coupled to the transmission and the washer will not agitate or spin dry the clothes. The reason that the motor coupler breaks before it should, it is that the user overloads the washer. People stuff the washer with too much clothes, big comforters, small placer rugs, snickers, etc.
Another reason is that the washer is used every day; normally the washer is used 3 times a week. So if you have a washer that is 5 years old and you use it every day, it has the wear and tear of a washer that is 10 years old.
Replacing the motor coupler is not hard to do, once you see how the repair is done. You will save at least $100 by replacing the motor coupler yourself.
I hope this this information has been of help to you in determining if the motor coupler is the problem when your Whirlpool top load washer is not spinning the clothes dry.
