Repairing procedure

To replace the rotating wheel (also known as the drum or pulley) on an LG washing machine model WM3400CW, you’ll need to follow a series of steps. These instructions are general and apply to many front-load LG washing machines. However, please consult your washing machine’s user manual for any model-specific instructions or safety guidelines. If you’re not comfortable performing these steps, it’s best to contact a professional.

Tools Needed:

• Screwdriver (Phillips and flat-head)
• Socket wrench
• Pliers
• Towel or small blanket (for laying the machine on its side)
• New rotating wheel (pulley)

Step-by-Step Guide:

• Unplug the Washing Machine: Ensure your safety by disconnecting the washing machine from the power supply.
• Access the Rear Panel: Move the washing machine to gain access to its back. You might need to disconnect water supply lines; if so, ensure you have towels ready for any water spillage.
• Remove the Rear Panel: Use a screwdriver to remove the screws holding the back panel in place. Set the panel aside.
• Locate the Rotating Wheel: The rotating wheel is attached to the back of the drum. Identify the bolt securing the wheel.
• Remove the Old Wheel: Use a socket wrench to loosen and remove the bolt holding the wheel in place. You may need to hold the drum from the inside of the washing machine to prevent it from turning. Once the bolt is removed, take off the old wheel.
• Install the New Wheel: Place the new wheel on the shaft where the old one was. Ensure it’s aligned correctly before tightening the bolt securely with the socket wrench. Again, you may need to hold the drum from inside to keep it from turning while you tighten the bolt.
• Reattach the Rear Panel: Once the new wheel is securely in place, reattach the rear panel of the washing machine with the screws you removed earlier.
• Reconnect the Washing Machine: Move the washing machine back to its original position. If you disconnected the water supply, reconnect it. Plug the washing machine back into the power supply.
• Test the Machine: Run a short cycle without laundry to ensure everything is working correctly. Listen for any unusual noises that might indicate the wheel is not installed properly.

Tips:

• Always refer to the user manual for any specific instructions related to your model.
• Keep track of all screws and parts you remove so nothing gets lost.
• If you encounter any difficulties or if the washing machine does not operate correctly after the replacement, contact a professional repair service or the LG support center for assistance.

Replacing the rotating wheel can extend the life of your washing machine and improve its performance. However, if you’re unsure about performing this task, seeking professional help is the best course of action. Here is a small photo report of the work carried out:
