Washer won't spin sounds like it wants to but tub does not move.

There is a clutch assembly under the tub that controls the tub and the agitator. It sounds like the problem is with that.

What is the model number of your unit?

see this causes and fix it. God bless you
Lid Switch Assembly If the washer won't spin the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

Motor Coupling If the washer won't spin the motor coupling might have failed. The motor coupling connects the motor to the washer transmission. It is designed to fail if the washer is overloaded in order to protect both the motor and transmission. Another common problem is the lid switch.

Drive Belt If the washer won't spin, check the drive belt. If the belt is broken or if it isn't tight on the pulleys the washer won't spin properly.

Door Lock Motor and Switch Assembly If the washer spin the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.
Motor Control Board If the washer won't spin the motor control board might be defective. The motor control board provides power to the motor as well as direction and force. If the motor control board is defective the washer may not work at all or function properly.

Drive Block If the washer won't spin the drive block might be worn out or may have come loose. Underneath the agitator the drive block connects the inner tub (the one that spins around) to the transmission. If the drive block wears out the transmission shaft will still spin but the tub may not - or it may spin slowly. This also usually causes a lot of noise. The drive block is relatively easy to replace.

Clutch Assembly If the washer won't spin, the clutch assembly might be worn out. The clutch assembly makes the connection between the transmission and the inner tub. It is designed to allow the tub to get up to the proper spin speed gradually. As the clutch wears out it may prevent the tub from spinning. The clutch is not repairable, if it is loud or not working properly it will need to be replaced.

Clutch Band kit If the washer won't spin, the clutch band kit might be worn out. The clutch makes the connection between the transmission and the inner tub. It is designed to allow the tub to get up to the proper spin speed gradually. As the clutch wears out it may prevent the tub from spinning. If the washer won't spin, this clutch band kit may need to be replaced.

Drive Motor If the washer won't spin the drive motor might be defective. This is not common. Check all of the other related parts to this symptom before replacing the motor. If the motor is visibly burned out or physically damaged It will have to be replaced.

Tub Bearing If the washer won't spin the tub bearing might have seized. This is a common problem and relatively easy to replace.

Tub Seal and Bearing Kit If the washer won't spin the tub seal and bearing might have seized. This is a common problem and relatively easy to replace.

Bearing If the washer won't spin the bearing might have seized. This is not common. The bearing doesn't require any normal maintenance. They generally go bad when the tub seal fails and allows water to leak past into the bearing.
Basket Drive If the washer won't spin the basket drive clutch might be worn out. The basket drive sits on top of the transmission and engages with the inner tub. If the basket drive wears out the tub won't spin.

Basket Drive Hub Kit If the washer won't spin the basket drive hub might be worn out. The hub is a set of plastic gears underneath the agitator. The basket drive hub kit is easy to replace with standard hand tools.
Transmission If the washer won't spin the transmission might be worn out or defective. There are numerous more likely causes when a washer won't spin, which should be checked first.

Possible that the motor is not moving , could be a faulty capacitor to the motor. Also check for the free movement of the agitator, if the shaft is tight then it can cause a drag on the motor.

It really sounds like the belt. You say it's in good shape but if it's loose or shiny from not having proper tension it wont have enough friction between the belt and pulley to actually work. If you've ever tried to move the drum when its full of clothes and water you know how much force id needed to function. Double check that belt tension and working surface.

If it doesn't fill it won't start any other cycle unless you move it ahead yourself. If it hums I am thinking it is trying to fill. Sounds like the valve is turning on to let water in but it is not getting through. My washer has a screen where the hoses go on and sometimes the screen becomes plugging with scale. If that is ok then the solenoid must be coming on but the valve is stuck. Does neither hot or cold settings work? Please rate my answer so I am rewarded points for it.

tub bearings may be frozen up. Can you move tub by hand?

You said,washer is full of water and will not spin. You hear the lid switch clicking. When you start it on spin cycle and hear a hum, the tub moves a couple of inches and then stops...shortly after it shuts off.


Some reasons this may happen
Washer won’t drain or spinn
1. Is the drain hose clogged, or the end of the drain hose
more than 72 inches (183 cm) above the floor?
2. Is the lid open? ............Also the lid switch can be faulty!!
The lid must be closed during operation.
3. Is there excessive sudsing?
Always measure detergent. Follow manufacturer’s directions.
4 If you have very soft water, you might need to use less
detergent.

Sounds to me like the lid switch can be faulty!!Then it acts like the lid is open.
Huuum

what a bogus website you are. you offer no free support and you should say so

sounds like may be in clutch see if you can help the tub start spinning when trying in spin setting...if trying to turn or turns some and stops most likey clutch slipping
