Why does the whirl pool agitator - lsq9544kq0 not work

It's the lid locking light that's flashing, the Lid Latch assembly needs to be replaced. It may be latching, but the switch inside it isn't working and doesn't recognize that it's latched.That's why it won't agitate or spin.
They have the part and a video on how to fix it at this parts company.
Other companies will have the part too.

This assumes that you have a basic Kenmore / Whirlpool top load, direct drive, neutral drain (it doesn't spin until the pump removes most of the water) machine.

First, see the Sears parts site for your washer:

http://www.searspartsdirect.com/partsdirect/part-model/Kenmore-Parts/Washer-Parts/Model-11082984810/0582/0153200?pathTaken=

and you'll see a list of major sub-components with diagrams and parts.

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.

Look at the section on the Sears site for Agitator, basket and tub.

See the part "Dog, agitator "

Remove 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.

Also see the following illustrated description of the above.

Them washer are what you call high efficiency washers.HE. They only use 1 gallon of water to wash them clothes. You go adding more than a teaspoon of soap and that washer is gonna have a cow. Over a period of time that soap gonna build up so much the washer is gonna just give-up the ghost. If you know you use the correct amount of soap there could be something in them pump.You need to remove the service panel and take a looksee at that tech sheet and see what it say about them light flashing. While you at it you may as well remove that cap and clean out that filter. That might put yall back in business. That tech sheet will be in there by that white box which is the motor control unit. The other stuff that the tech sheet error chart might reveal is located on the topside. Good luck on dat repair mon ami.

This is an automatic feature to dry out the pipes and prevent mold. The next time you turn on the pump after leaving these tubs for a few weeks you get lots of black **** in the water and this is what this feature prevents. Sounds like the tub is working fine :)

Humming could mean a stalled motor. These machines also have a coupling between motor and gearbox which can fail. However, the pump is attached to the motor, so if it's not pumping it probably means the motor isn't spinning. Check motor and/or gearbox.....Nomess

Broken coupling

your agitating belt might be slipping or worn, try holding the switch down with a pencil, and keeping the lid open and see if the agitator is moving or sluggish..good luck.

Move the top of the agitator clockwise then counter clockwise, it should lock and not move counter clockwise. if it does, you have a broken pawl.

if new did you remove shipping strap in back..the unit cant lean more than 2 degrees..make sure clothes are even in tub..try to wash clothes alike..

well they refuse to adress your issue under a warr. beacause of age , but im certain that a whirlpool auth. servicer will glady adress your issue. As for the F1 generally relates to a faulety control board. but would want( a serveicer ) to check in more detail before jsut askin you to replace the board
