Sunita Contreras, it is possible that the clutch dogs have worn so much that the washer no longer agitates properly. The agitator is removed by first pulling off the gitator cap and inner cap. then unscrew the 7/16" bolt founf under teh cap and pull straight up on the agitator assembly. the clutch and cluthc dogs that provide the agitator action are found in the upper portion of the agitator assembly. Check [http://www.youtube.com/watch?v=jCeSvQtBA0E|this video] and get the service manual [https://secured.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/f7e2147fa98b28cf85257122007475cb/|from here.] Hope this helps, good luck.
