The top part of my agitator moves slightly, and sometimes not at all. The bottom part moves but the clothes at the top don't seem to move.

The Agitator In your washer has two parts. The bottom half will move back and forth. The top half (spindle) will move in one direction (clockwise). Most of the scrubbing or washing is done by the bottom half of the agitator. The spindle is responsible for pulling the clothes down from the center and sending them to the bottom where they will be scrubbed. As the clothes circulate, they will all be washed.

It is not the best of designs.

Sometimes, clothes will get stuck at the bottom when the agitator dogs are worn out. Check to see if the upper part of the agitator is working during the wash cycle. If it isn't, the clothes stay at the bottom and just move horizontally, not from the bottom to the top. The clothes then get stuck in the gap between the lower agitator vaens and the bottom of the agitator. This is a very easy repair, you need only a socket wrench set (SAE) with an extension.

You can also buy the dogs (pawls) by themselves in a pack of four for about $5.

When I first saw this agitator set-up, I asked myself, 'What were they thinking of?'.

Good luck.

There is a metal piece that is inside the plastic agitator that is broken. I connects the agitator to the rod that drives it. It has an oval shaped slot inside and is ribbed on the outside. I have the same problem. Simple to replace, I just need to find the part.

If the bottom agitates and not the top, the problem is likely the 4 "agitator dogs" designed to allow the top agitator to turn only one way.

On the Sears parts site:

http://www.searspartsdirect.com/partsdirect/getModel!retrieve.pd?pop=true&modelNumber=110.26902691&pop=flush

replace the 110.26902691 with your model number (lift the lid and the model number should be printed on the cabinet) and look at the section on the Sears site for Agitator, basket and tub.

This is what they look like:

#21 on diagram Dog, agitator (4) Number:3366877Substitution:80040 $9.25Remove the fabric softener unit, lift the top agitator cap (use a screwdriver) and you should see a plastic part in the center of the top agitator with a 1/2" square drive.

Remove the drive and lift off the top agitator. Turning it over you should see the 4 "dogs", replace these and the top agitator should turn in one direction only.

Replace the 1/2" drive, the cap and fabric softener unit and the top agitator should work.

2 things
First is that I assume this not to be a 1 piece agitator. If it was the whole thing should turn back n forth Make sure its top (nut) fastner is tight. Usually just push down slightly and turn Clockwise.

A sectioned agitator has a lower section separate fro the upper. The lower can be attached to the agitator shaft and will move back n forth but the top has teeth that engage 1 way and allow slippage when the agitator comes back the other way. This "ratchet" action (some whirlpool older models that i have seen) if it has teeth ground off or grease build up under the teeth can cause them to stop agitating and just kind of sit there.

Drain and remove the clothes,
Take the top by hand and try turn it back n forth see if bottom moves. If the top is slipping and the bottom stays put remove the top nut (turn Counter Clock Wise) and try remove the upper section. If you can get it off you may be able to see why its not turning, and get the part to fix it.

Please let me know if this helped you. Rate me with as high a mark as you can. thanks and good luck.

You need to replace the agitator dogs inside the clothes mover (agitator). take of the top then the cover, remove th bolt and take the top half off. you should see four "dogs" that need to be replaced.

If it is a Whirlpool or Kenmore make washer you probably stripped the "dog ears" in the agitator. They give you the duel agitation that makes your clothes cycle from top to bottom of the machine. Should only rin you around $8.00 or so. Hope that helps.

This washer has a set of cheap plastic dogs that grab the inside wall of the upper agitator to move the clothes downward and help them get a better cleaning. The older style These dogs will wear out. To test whether or not these are bad just grab the agitator while in wash mode. The dogs should advance the top portion easily. If not then they are worn out. To replace them you must remove the agitator and sit it on the floor. Hold the base down with your feet and yank the top upwards. After seperating the 2 pieces you simply install the new dogs and line up the bottom with the top being careful not to break the little tabs on the bottom agitator that hold the top in place. The newer style you simply pop the cover of the agitator and use a 3/4 drive extention to unscrew the upper agitator. replace the dogs and put the top back on. Nothing could be easier.
