SOURCE: loud noise while agitating in wash cycle

If you begin dissassembly from the tub down, you wil come to the transmission with the spindle sticking out of it. If you undo the bendable tabs all around the transmission it comes apart in two halves. Careful, its full of oil. The spindle has a plastic gear bolted to the bottom of it. It meshes with other gears in the tranny. It has sheered teath and is making the noise.

not nesseccarrily your pump, possible you have a rear bearing going bad, which will sound as if a helicopter is coming through your laundry room. ( noisy pump can be the issue , honestly a better and cheapre problem to have) in order to determine if its apump problem you can remove the lower access panel and unplug the pump then start the spinn cycle, if it still loud the pumpms not hte issue.

SOURCE: whirlpool washer agitator not working

HI. the internal components that make up the agitator should be inspected for damage.

The agitator is fastened to the agitator shaft and its movement is driven either by splines or a simple clutch assembly. The splines are usually plastic or rubber nubs on a cylinder that fits over the agitator shaft. If the nubs wear down, the shaft will not turn properly or it will turn weakly. If the agitator is moving in only one direction, the likely cause is the clutch assembly. The clutch has dogs that depress and pop up with each turn. If those dogs are worn, they will not engage properly and the agitator will turn only in one direction. Another issue that might cause this disruption is the Motor coupler.

Washers with a direct drive motor have a motor coupler instead of a belt. The motor coupler consists of three plastic disks (or tri-stars) with interlocking tabs. Those tabs can wear and break which results in slippage. The slippage causes little or no power to be transferred to the transmission. A worn motor coupling can result in weak or no movement of the agitator and spin basket. Inspecting the motor couplers requires removing the motor, which is fairly easy to do.

Remove the cabinet. Locate the motor. The pump is mounted to one side of the motor. You do not have to remove the hoses from the pump unless they prevent you from moving the pump out of your way. If you must remove the hoses, label where they connect first. To disconnect the hoses, pinch the wire clamps with pliers (or loosen the screw) and slide the clamp farther up the hose. Slide the hose off of the pump port.

There are two clips that secure the pump housing to the motor. Use a screwdriver to pry up the clips and remove the cover. Next, slide off the pump to reveal the motor. Disconnect the wiring harness from the motor, do not pull on the wires themselves. The motor typically is secured with retaining clips and bolts. Remove the bolts and use a screwdriver to pry up the clips (if present). Remove the motor.

Mounted on the shaft of the back of the motor you will find the motor coupler. Separate the three disks and inspect them for damage. If you find cracks or excessive wear, replace the coupler.

**(((If the motor couple is in good condition, replace the agitator components and clutch assembly as well.)))


AGITATOR REMOVAL GUIDE


The agitator is fastened to the agitator shaft and its movement is driven either by splines or a simple clutch assembly, which is removable as well. The splines are usually plastic or rubber nubs on a cylinder that fits over the agitator shaft. If the nubs wear down, the shaft will not turn properly or it will turn weakly. If the agitator is moving in only one direction, the likely cause is the clutch assembly. The clutch has dogs that depress and pop up with each turn. If those dogs are worn, they will not engage properly and the agitator will turn only in one direction.

Various makes and models differ in how the agitator is removed. In some newer models, the agitator just lifts straight up and out. However, in most models you will have to preform a combination of the following steps. First remove the fabric softener dispenser, if any. It should either lift or screw off. Next remove the cap. It may lift off, screw off or failing that, it may need to be pried off.

Beneath the cap some agitators are secured in place by a bolt. Use a socket wrench with an extension to remove that bolt. Some Maytags may have a screw near to the bottom of the agitator post that must be removed. Now try to lift the agitator straight up, possibly with a little back and forth rocking motion. Use caution when pulling, the agitator may come loose suddenly and hit you in the face or send you flying backward.

If the agitator is particularly stubborn, you can loop some rope under one side of the agitator at the bottom and then up over a broom handle. Now loop it again under the other side of the agitator and back up to the broom. Brace one end of the broom handle against the top of the washer and lift up on the other end. Double check that you have removed anything that may be securing the agitator in place. Do not use too much force or you may damage the washer cabinet, agitator or injure yourself.

hi Rick.
Reasons a washer will make noise during spin mode:
1. Main tub bearing faulty
2. Main drive pulley
3. Motor coupling worn
4. Bad clutch
5. Worn out drive belt
6. Clogged or damaged drain pump
7. Transmission is worn out
8. Shock absorber (front loader washers)
9. Springs or dampening straps (top load washers)
10. Agitator directional cogs aka "agitator dogs" (top load washers
When the washer spins, it rides on a bearing that allows the tub to move freely with zero resistance. If this bearing is worn out, a loud noise will be heard when the washer spins. A good way to tell if your washer problem is the main tub bearing will be that the washer noise will get worse or louder as time goes on. This means the bearing is becoming more worn out and close to complete failure. The bearing in your washing machine is a circular metal object that has many small little metal balls inside. These small metal balls inside the bearing sit in a track and move when the washer is spinning. If the tub bearing begins to wear out, usually the small metal balls inside can fall out one by one causing the noise you hear. (If your washing machine is a front load washer, open the door and turn the drum by hand. If you hear a rubbing sound or the drum spins uneven, then the main tub bearing is most likely bad and needs replaced.)

Washer has noise during spin cycle

The bearing may also be without lubrication. If the sound you hear is more of a squeaking noise than a grinding noise, it may mean the bearing needs to be lubricated with a mechanical grease. If the sound is more of a grinding noise, then this usually means the bearing is falling apart and will need to be replaced ASAP. If you suspect your washers main tub bearing is worn out, the repair process is one of the most difficult to perform yourself. A worn bearing can also damage the tub of the washer. This means the tub (inner or outer) may need to be replaced also.
A washer making a loud noise during spin cycle can also be caused by a faulty drive pulley. The pulley is what the belt (if applicable to your washer) rides on to spin your washers tub. The pulley can be made of plastic or metal. It could be simply worn out or just loose. To find out if the drive pulley is causing the noise, you will need to take the washer apart and inspect the pulley for signs of damage.
WASHER MOTOR PULLEY
The motor coupling could also be the cause of the loud noise. The motor coupling in your washer connects the washers transmission to the motor. It is made of plastic and built to break if the washer gets overloaded. This is so the motor and the transmission do not become damaged. The motor coupling is an easier repair and can be done by most people.




Washer Washing Machine Motor Drive Coupling Coupler
The clutch in a washing machine connects the inner wash tub to the transmission. The clutch lets the washer get to the proper spin RPM in a gradual way. If the clutch is worn it can make noise when the washer is spinning. A bad clutch needs to be removed and replaced to stop the noise.
Washing Machine Clutch
The belt in your washer can become worn and cause noise while spinning. If worn out, replace the belt. Replacing the drive belt on a washing machine is an easy task and can be ordered online for less.
Washing machine belt
The drain pump in your washer that drains the water out could be clogged or damaged. While in spin mode, your washer may drain out the water by using the drain pump. If the loud noise only happens at certain intervals during the spin cycle, it may be the drain pump. Usually this can be fixed by simply removing the drain pump and removing any debris that may be clogging it up causing the noise.

The next part of your washer that can be causing a loud noise is the transmission. If the transmission is bad, usually the cost to fix this outweighs the cost of a new washer.
If you have a front loading washing machine, they all have shock absorbers. The shock absorbers are used to center the tub movement while in the spin cycle. These shock absorbers are connected from the washer frame to the outer tub. If the shock absorbers in your front loader become weak the washer will make a loud banging sound during the spinning cycle.
Shock Absorber for washing machine
Top load washers usually have springs or dampening straps holding the tub centered. If a spring or strap falls off or becomes weak, a loud noise will be heard in spin mode. Simply replace the strap, spring, or springs to remedy this issue.
Washing machine suspension springs
Agitator directional cogs are used to operate the upper part of dual action agitators (Top load washers). They engage the cogs on the inner area of the agitator as it turns in one direction. They release when the agitator reverses its direction. This lets the top part of the agitator to ratchet in only one direction. The bottom part will agitate in both directions. The cogs are made of plastic and wear out with regular use. They will start slipping and make a grinding noise. Another way to be sure that this part is bad is if you notice the top portion of the agitator does not move in a smooth motion. Removing the top half of the agitator to see if the cogs are worn out.

Whirlpool Model #: WTW4800XQ making a loud grinding noise during or at end of spin cycle. Help!


I have a similar model (WTW4850XQ1) that was making a very loud grinding/screeching noise during the agitation and sometimes the spin cycle. I unplugged and turned it on its front to get underneath and exposed the motor/transmission unit. Took the cover off the belt drive assembly and my drive gear was loose. Simple tightening down of the nut was an easy fix for me. But some times those plastic gears between the drive pulley assembly and transmission crack or the teeth wear down (think it's called the CAM). That is a fairly cheap and easy fix as well ($35). Repair Clinic website has free videos on how to diagnose and fix issues and parts as well. Worth a look.
