It wont empty out completely clothes are still. The drum itself is very loose not sure if it suppose to be that way. It does not spin very fast . does this particular model have a belt that needs to be tightened. Washer is only a few years old

A silly one to check is are you over filling the drum with clothes? (Yes, I've done that). Wet clothes are significantly heavier than dry ones.
Check the large rubber seal the door fits into. Make sure it is clean, not damaged and fitted correctly.
When the machine is empty and turned Off turn the drum inside by hand. It should turn smoothly with a little bit of resistance.
Look carefully at the drum as it turns to see if the drum itself is damaged. You might need to CAREFULLY run you hand around the inside edge, nearest the big door seal, to feel for damage.
Listen to the noise it makes as you keep turning it. The sound should be a sort of quiet 'hiss' from the bearing turning.
Try pushing the drum up and down. It should swing a short distance backwards and forwards but not up and down.
If these checks are all OK You will need to get an engineer to look at it as there is possibly something trapped or loose inside the main body of the machine.

Many different designs in washing machines. Need model #.

If it is under warranty, call Whirlpool at 1-866-698-2538. If it is out of warranty, try running the washer with no clothes in it in spin cycle. If it runs fine empty, it may be that when you had clothes in it they were not balanced evenly in the tub. If it runs off balance when empty, then a spring may have broken or come off. Contact an appliance repairman.

Check the drive belt and tension arm spring and make sure it has not dislocated itself. The drive belt is the most likely problem if the motor is running during the spin cycle.

with a lot of the machines now they wont go into spin mode if the drum is not balanced properly, like say you had a load of towels in their, well it wont spin as its to unstable to spin without wobbling around so it simply stops at the spin cycle and does nothing, you can try this by turning it on with no clothes in and see if it will go into the spin cycle with no clothes in, if it does then chances are its not weighing the clothes properly and would end up costing a fortune to put right as it sounds like you spent a lot of money on parts all ready, so give i a try with no clothes in and see if it will spin, have you tried turning the drum by hand when its switched off to check for any grinding noises or jerking when you try to turn it by hand, im not sure how the balance sensor works or even where it is as its a new feature in the last few years but people are now starting to have problems with this feature and it stops the machine from spinning leaving the clothes soaking yet, so give it a try empty and see what happens

Check the shocks on the drum to make sure they are ok. if they wear out the drum spins out of balance and the computer wont allow it spine because it would WALK and damage itself.

Hi
Does this happen every time???
If YES... then the machine is not balanced on the floor well.... the 4 stands on which the machine rests have adjustable screws... You will need to fasten or loosen the nuts that will adjust the height of the legs on which the machine rests.... all the 4 legs need to be firmly on the floor .... If one is too high then the machine rocks on its side...

If NO.. only sometimes...
You are overloading the machine with heavy clothes... distribute your wash clothes by weight...

Let me ask you who told you to change the brushes... Im curious!

tyr removing the lower acees panel from the uint , ther is a "button trap" located there to catch debris from entering pump assy, chances are its clogged and if it cant drain all the water it wont go into high speed spin, also you MUST use an HE detergent. HE detergent specifically designed for front loading washers

moter 1st i would say thx nick
