Double check your symptoms. The problem you are having could be a motor coupling, or a lid switch malfunction.
If the washer will fill, will not agitate or spin, but will STILL drain, these are the symptoms of a broken motor coupling. This is a very simple and inexpensive
repair. The following link explains step-by-step how to replace one:http://www.fixya.com/support/r385252-replacing_motor_coupling_whirlpool_top
The part number is included in the link I provided. You can purchase a replacement on line at appliancepartspros.com for about $11.
If the washer fills and agitates, but stops at the rinse cycle, or, if the washer fills, then stops, this is a common symptom of a lid switch malfunction. The washer will NOT drain either. The following link explains how to access and/or replace one:http://www.fixya.com/support/r385198-replacing_lid_switch
The lid switch is usually mounted under the washer
top casing, on the right hand side on most top load models. It is activated by a plastic piece on the lid (called a "Lid Strike") through a small hole on the rim
of the wash tub opening. In many cases the lid strike breaks off the lid, or the lid switch becomes loose and no longer makes contact. Inspect the lid to make sure the lid strike is still intact, and then inspect the mounting screws (adjacent to the small opening on the wash tub rim
) and make sure they are snug.
The part number for a replacement lid switch for your model washer is 3949247. It can be purchased at appliancepartspros.com for about $24.
If you have questions please let me know. A motor coupling repair is a little more involved than a lid switch. I would recommend checking the switch first. It may save you from having to take the washer apart any more than you have to.
I hope you find this information helpful.
