LA6800XTWO Whirlpool washer: tub fills and empties but no spin or agitation

I would start by checking the belt on the motor could be slipping when u put full load in washer. also check that pulleys are not loose.

My Whirlpool WTW6600 had the same problem. The tub no longer floated up and down on the center shaft, so it only spun, not agitated. You must remove the tub (with some effort) and lightly sand / clean the center shaft. Lube it lightly with wheel bearing grease so that after it is reassembled, you can pull the tub upward and feel about 1/2" movement. This will enable the proper gear assembly to engage. It can spin when it rests at the bottom of its travel, but once you fill the tub, it floats, moving upward, and engaging the agitation gear. Good Luck!

It could be the agitator clutch dogs that are worn out. Best off to call a certified service technician.

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:

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

Following is the Whirlpool installation and maintenance PDF on how top load, direct drive washers work with a troubleshooting section.

Following is the Whirlpool parts list for commercial top load, direct drive washers although the consumer washers are basically the same.

The problem seems to point to the Agitate Cams in the transmission that raise and lower the Agitate gear on the main transmission shaft. These are relatively inexpensive to replace.

I'd also check the splines on the main agitator shaft and the two pronged "washer" on top of it.

remove the agitator. there is a cone shaped block on the agitator shaft and locked to the tub via a large lock nut. spin tube has 2 tabs that lock into slots on top of block. these can strip out and cause the spin tube to spin inside block. watch it and turn machine on spin. tub can also drop and drag on bottom of outer tub. if this is it replace block and gently straighten tabs on spin tube.

it might be jammed or there might be dirt or some sort of a clog. I would suggest you clean it out.

Your lid switch is bad. If you give model number I can give you the part number you need.

sounds like a broken coupler, looking at your wiring diagram this unit would agitate with lid up right? then lid sw is not your problem, if it does not drain either then motor must be not turning over, so i would check the capacitor first. (it on the back panel behind the tub)

Need a new drain pump. I just had this problem. found a drain pump on ebay for 60. Replaced and running mint again. don't keep trying or you will burn out your motor.

yes unless pressure switch(water level switch)detects proper fill level wash will never start agitating some washer will not spin if switch does not detect empty tub
