My LG direct drive washing machine Gear system is broken. Same issue when I replaced it. Checked clutch regulate motor and work fine.

Examine the gearbox; it can be the cause of the issue.
Examine it for damage, such as stripped gears or worn-out bearings, and repair it if required.
Examine the clutch assembly: The clutch assembly engages and disengages the transmission and drive motor.
Check to see if the clutch assembly is in good condition and not worn out.
Examine the drive belt: The drive belt turns the drum and links the motor to the transmission.
Verify that the drive belt is not slack, worn out, or damaged.
Check the tub bearings: The washer's drum is supported by the tub bearings.
The gear system may malfunction if the tub bearings are worn out.
Contact the manufacturer: If none of the above solutions work, it may be necessary to contact the manufacturer for further assistance. They can provide more detailed troubleshooting steps or recommend a service professional to diagnose the problem.

may be there will be fault in the motor shaft ..............or it may happen due to heavy load try with normal load and also check the motor shaft

This is a neutral drain direct drive machine which drains the water first prior to spinning. After draining out the water completely, the motor pauses then restarts to spin the tub. It is possible that the problem is in the lid switch. If the motor is running during the spin cycle then the lid switch is good, otherwise it is indeed the problem.

The problem can be either in the brake particularly the cam driver or the clutch assembly. The clutch hub is attached to the spin pinion gear and as the spin pinion gear turns, the clutch hub also turns. The clutch lining is forced against the clutch hub by the clutch spring. As the clutch hub turns, friction between it and the clutch lining causes the clutch lining to turn. As the clutch turns, the tab that holds the clutch spring on the lining, contacts the brake cam driver, releasing the brake. The tab on the clutch lining remains in contact with the brake cam driver, holding the brake released and then providing power to the spin tube through the brake release.



The basket will not spin if the brake cam driver is broken because the brakes cannot be released. If the clutch spring is weak, the friction between the clutch hub and the clutch lining is not sufficient for the clutch tab to push the cam driver and release the brakes.

Check and replace, if necessary, the brake cam driver and the clutch assembly particularly the clutch spring and the clutch lining.

Hi,

If it also makes a noise, then more likely it's a broken Motor Coupler.

If not, you need to investigate :-

Lid switch If the lid switch is defective, the washing machine may not agitate or function at all. The switch is inside the washing machine main housing near the door frame. Often you have to raise or open the top or front of the washing machine to get to the switch. If it's defective, you need to 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. (Some washing machine belts are designed with special characteristics not found in automotive belts.)

Clutch If your washer was made by GE®, it may use a clutch for agitating the clothes. As the clutch wears out, it may prevent the washer from agitating well or at all. If the clutch is worn, you need to replace it. For this job, you probably want to hire a qualified appliance repair technician.

Drive motor Many washer brands use a reversing motor. For agitation the motor runs in one direction, for spinning and draining, the other. It's possible for a motor to burn out in one direction and continue to operate in the other. If this happens, you need to replace the entire motor.

Drive pulleys The motor or transmission drive pulley may be worn and unable to turn the drive belt. If so, replace the pulley.

Transmission The transmission could have either of these problems:

• Older washers produced by Whirlpool® have a transmission with an electro-mechanical shifter. If the shifter becomes even partially defective, the unit may not agitate properly or at all.



• The transmission may have a worn or broken gear, or some other internal problem.

If you suspect a transmission problem, you may have to call a qualified appliance repair technician to repair it.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Agitation is the most complex operation in any washing machine. There are several components working together to make it agitate and as a result it is a challenge to isolate the problem or problems involved. Here is what to look for:
If your washer doesn't agitate, check these:

Lid switch
Motor coupler
Belts
Clutch
Drive motor
Drive pulleys
Transmission
Agitator
Lid switch If the lid switch is defective, the washing machine may not agitate or function at all. The switch is inside the washing machine main housing near the door frame. Often you have to raise or open the top or front of the washing machine to get to the switch. If it's defective, you need to replace it.

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. (Some washing machine belts are designed with special characteristics not found in automotive belts.)

Clutch If your washer was made by GE®, it may use a clutch for agitating the clothes. As the clutch wears out, it may prevent the washer from agitating well or at all. If the clutch is worn, you need to replace it. For this job, you probably want to hire a qualified appliance repair technician.

Transmission The transmission could have either of these problems:

• Older washers produced by Whirlpool® have a transmission with an electro-mechanical shifter. If the shifter becomes even partially defective, the unit may not agitate properly or at all.
  
  
• The transmission may have a worn or broken gear, or some other internal problem.
  
  

If you suspect a transmission problem, you may have to call a qualified appliance repair technician to repair it.

Agitator The inside of the agitator--where the transmission shaft attaches--can become worn, and strip out the spline that allows the agitator to properly grip the shaft. Then the transmission shaft rotates back and forth as it should, but the agitator doesn't move properly. If this happens, you may need to replace the agitator and/or the transmission spline.

Ok, your direct drive system is experiencing gear breakdown issues. the transmission(gearbox) is stripped and causing the grinding situation. The clutch is ruined as well. you may have some minor electrical motor trauma as well. i recommend disassembling the unit if possible, to inspect the direct drive and transmission/clutch assembly. you should see the drive/transmission under the drum assembly.

Check thoroughly for trauma spots. replace the direct drive assembly if damage is noticed.

There should be some kind of oil leakage around the drive assembly. inspect the motor as well.

If the motor is not smoking or humming, it should be fine. More than likely, it will be the drive and transmission assembly that will need to be replaced.

Please rate and have a great day:)

Can you move the basket by hand...if so you need a basket drive. If not you have a bad clutch or gear case

It doesn't agitate If your washer doesn't agitate, check these:

It's noisy Most noises from a washing machine occur during the spin cycle. If you hear loud thumping during the spin, the load of clothes may have become unbalanced. Stop the washer and redistribute the clothes, then re-start it. Repeat these steps if necessary.
