My topload whirlpool agitates fine, but tub doesn't turn during spin cycle. Motor runs, and it seems to follow the timer. So I replaced the drive coupler, which was wore, but not broken. I replaced th

If your Top Load Washer will not Spin or Agitate Check the Following

Lid Switch
This is the most common reason for the washer not spinning or agitating. This is easy to check. You will need to remove the switch, this varies with model type but the testing will be the same. When the lid is closed the switch should have continuity when the lid is opend the switch should have no continuity. If it differs replace the Lid Switch.

Timer
To check the timer you will need to refer to the wiring diagram or disassemble to access the motor. Check the leads from the timer to the motor when turned to a wash cycle this should have 120 volts. If not replace the Timer, if it does the timer is not the problem.

Motor
To check the motor you will need to disassemble the washer to access the motor. First you can check the motor windings, to do this remove the plug and connect ohmeter to terminals. Refer to the tech sheet or service manual for the proper reading. Check motor for shorts by connecting ohmeter to terminals and motor housing should have no continuity. Connect voltmeter to motor wire connector and check for voltage. You should have 120 volts, if you do and the motor does not run replace the motor. If it does not have power the problem is elsewhere.

Belt
If your washer is a belt drive type make sure the belt is tight. Check for black soot from belt wear. Replace if it has excessive wear or broke.

Motor Coupler
This is a fairly common problem with direct drive machines but inexpensive and easy to replace. The Motor Coupler transfers power from the motor to the transmission. The following video will walk you through the replacement of the Motor Coupler.

Transmission
The transmission does not usually fail. To check this on a direct drive remove the motor and then turn tub inside. If it spins freely with no noise the problem is elsewhere. If it is noisy it needs replacing this is expensive and depending on the age of your machine you may not want to replace it. On a belt drive remove the belts and spin tub.

No spin, try these:

Using a multi meter check for continuity the door switch, which when bad may not allow agitation or spin. The lid switch assembly can fail either mechanically or electrically.

Check the clutch, brake assembly and transmission, one way to check for slipping is to get under the machine after a spin cycle ( this is if u get a lil spin but not much leaving clothes still wet) mix in a spray bottle a lil water and some dish detergent, then spray it on the clutch assembly ( the metal round pc. Connected to the tranny) if it sizzles and steams up then u know its bad and slipping. Another way to check clutch if u get no spin at all? Is to take it out and use ur hand to try and turn the inner spring assembly pushing it around the inside? If its very easy, it BAD should be hard to push by hand.


Next check the motor coupler which engages the tub and tranny to the motor. ( if its bad u usually get no wash or spin or very little of either)

Next check for a loose, worn or broken belt if belt driven.

On some front load models u may need to check the STATOR assembly.
The stator is essentially one half of a motor, it interacts with the tub by creating a strong electro-magnet. If the stator burns out the washer won't spin or agitate. Check the stator for continuity. This part is often misdiagnosed.

LOT OF THINGS TO CHECK, THE BELT LOOSE OR WORN, THE CLUTCH, THE TRANNY, THE BEARINGS BOTH TUB SEAL AND BEARING, THE REAR DRUM BEARING, the balance or counter weights.

THE DRIVE PULLEY- If the washer is making a loud noise the drive pulley might be worn out, cracked, loose or bent. Remove the drive pulley and inspect it carefully. If it is damaged or defective replace it.
THE TRANSMISSION, THE MOTOR COUPLER, THE MOTOR DRIVE BEARINGS,
THE DRIVE MOTOR- If the washer is making a loud noise the drive motor bearings may have worn out. Washer motors are normally almost silent when they run. If the motor is run without a belt hooked up to it and it's loud it will have to be replaced.

Your main switch needs replaced. The motor that drives the switch operates because it goes through the other cycles, so the switch must be bad.

Hello friend,
The spin bearing or basket drive may be worn or seized. These components allow the inner tub to spin freely inside the outer tub. When this is the problem, you usually hear a loud sound during the spin cycle. Call a qualified appliance repair technician.
In case of the agitator not moving check the following:
Motor coupler
Many washers produced by Whirlpool® use a small, relatively inexpensive motor coupling. It's plastic and rubber and is mounted to the shaft of the motor on one side, and to the transmission on the other. Over time, the coupler wears out and fails. If this happens, you need to completely replace it.
Belts
Many washing machines have one or two belts. If a belt is broken or badly worn, you need to replace it with a genuine belt from the manufacturer.

Check the above, It seems that your washer needs a repair and would not be possible to do it yourself. So yau will have to call a technician.

Do feel free to get back to us in case of any other assistance if problem is not solved or if you have any other query.

Thanks

When the clothes are wet at the end of a cycle, check these:

Motor coupler
Spin cycle
Siphoning
Water-inlet valve
Motor coupler To test the motor coupler, re-start the washer in its spin cycle. Let the machine run for a minute, and then open the lid and notice whether the tub is spinning: 

• If it's spinning when you lift the lid, the coupler is fine.



• If it isn't spinning--and your machine was produced by Whirlpool®--you may have a broken coupler. Many Whirlpool-made washers use a small, relatively inexpensive device called a motor coupling. This plastic-and-rubber component is mounted to the shaft of the motor on one side, and to the transmission on the other. Over time, the coupler wears out and fails. When that happens, you need to replace it completely.

Spin cycle If the washer doesn't reach its proper spin speed, the clothes may be too wet at the end of a cycle. Check to be sure the load is properly balanced and run a spin cycle again. If the clothes are still wet, you may have a worn or loose belt (Maytag®), a worn clutch (GE®/Hotpoint®), or a worn motor pulley or tub bearing. Replace the applicable component. 

Alternatively, there could be clothes caught between the inner and outer tubs. Read the "It spins but won't pump" section of the "It won't drain" section. Also, there could be other things that cause friction on the drive train. Seek the assistance of a qualified appliance repair technician.

Siphoning If the water that pumps from the machine goes right back into the machine after the spin cycle, it may be because your washer is siphoning the water from a laundry tub with a slow drain, back into the washer. Try to improve the draining of the laundry tub. (Is there something stuck in the drain?) Also, be sure the drain hose doesn't reach more than about 4 inches into the laundry tub. If it does, cut off the excess.

Water-inlet valve Water-inlet valves eventually fail. One problem that may develop with a water-inlet valve is that it can no longer completely shut off when the electricity is turned off to it. Then, the valve may leak and drip water into the clothes tub--you may notice that your washer has water in it when you haven't used it for a few days. To fix this, replace the valve. 

No belt on your machine. Sounds like motor coupler that joins motor and transmission is broken. Very inexpensive part but a few steps involved in getting machine disassembled Look up YouTube video on replacing motor coupler on Whirlpool washer.

you can check the direct drive coupling between the motor and the transmission, if the coupling is good and not broken then you have a transmission problem

yes the problem parts of the transmission if your going to keep it have new transmission installed

Faulty spin windings on motor. Regards Advisor
