Identifying the Problem

A drum that won’t turn can be caused by several different issues. By narrowing down the cause, you can save time and avoid unnecessary part replacements.

1. Listen for Strange Sounds

   • A grinding noise often indicates a worn bearing or jammed gear.
   • A continuous whirring sound with no drum movement suggests a broken belt or motor problem.

2. Check for Physical Obstructions

   • Look for lint, small items, or other debris inside the drum.
   • Open the lid and examine the inside of the tub for trapped clothing or accessories.

3. Observe the Machine’s Response

   • If the machine cycles normally but the drum remains still, the belt is likely broken or disconnected.
   • If the machine stops entirely during a cycle, a lock or motor issue may be present.

Once you have an idea of the potential cause, proceed to disassembly.

Removing the Front Panel

The first step to accessing the drum is to remove the front panel of the washing machine.

Step 1 – Open the Door

• If the door is locked electronically, press the unlock button or wait for the lock to release after a cycle completes.

Step 2 – Remove the Bottom Handle

• Locate the small screws that secure the handle to the panel.
• Unscrew using a Phillips screwdriver.

Step 3 – Remove the Panel Screws

• The front panel is held in place by several screws around the perimeter.
• Use the appropriate screwdriver or socket to remove them.

Step 4 – Lift the Panel Carefully

• Once all screws are removed, lift the panel toward the back of the machine.
• Disconnect any wiring harnesses that may be attached to the panel.

With the front panel off, you now have access to the control board, motor, and belt assembly.

Checking the Door Lock Mechanism

The door lock prevents the drum from turning during operation. A fault in this system can cause the drum to stay immobile.

Step 1 – Inspect the Lock Lever

• The lock lever is usually located on the side of the machine.
• Check for visible damage or misalignment.

Step 2 – Test the Lock Sensor

• With the machine unplugged, press the lock button on the control panel.
• Observe whether the lock lever moves into place.
• If the lever fails to engage, the lock mechanism may be defective.

Step 3 – Verify the Motor Activation

• Connect the multimeter to the motor terminals.
• With a power source applied, check for proper voltage supply.

If the lock or motor fails these tests, consider replacing the lock assembly or motor. A faulty lock will also be reported in the error codes on the display.

Inspecting and Replacing the Belt

A broken or slipped belt is the most common cause of a stuck drum. This section walks you through checking and replacing it.

Step 1 – Locate the Belt

• The belt runs around the motor pulley and the drum pulley.
• It is often a rubber loop with a reinforced seam.

Step 2 – Check for Wear or Breaks

• Visually inspect the belt for cracks, fraying, or broken segments.
• Gently tug the belt; it should flex slightly without resistance.

Step 3 – Remove the Old Belt

• The belt is usually secured to the drum pulley by a small bolt or clamp.
• Loosen the bolt or clamp with a socket.
• Slide the belt off the pulleys.

Step 4 – Install the New Belt

• Place the new belt onto the drum pulley first.
• Thread it over the motor pulley and align the belt with the tension slot.
• Re‑fasten the bolt or clamp, ensuring the belt sits evenly on both pulleys.

Step 5 – Test for Smooth Operation

• With the front panel still removed, turn the drum manually to confirm it rotates freely.
• If it turns smoothly, reassemble the panel and perform a test cycle.

Removing the Drum for Deeper Inspection

If the belt is in good condition but the drum still won’t turn, the issue may lie deeper—inside the bearing assembly or the motor coupling.

Step 1 – Drain the Drum

• Place a drain pan under the machine.
• Remove the drain hose from the back to allow any residual water to flow out.

Step 2 – Disconnect the Drive Belt

• As described earlier, remove the belt from the motor and drum pulleys.

Step 3 – Access the Drum

• The drum is usually held in place by a set of guide rails or a bearing housing.
• Use a socket set to loosen and remove the retaining screws that secure the drum to the housing.

Step 4 – Lift the Drum Out

• Carefully lift the drum out of the machine’s shell.
• Place it on a padded surface to avoid scratching.

Checking for Debris and Bearing Condition

A drum may appear stuck because of hidden debris or worn bearings.

Step 1 – Inspect for Debris

• Examine the inside of the drum for lint, hair, or small objects.
• Remove any that you find with tweezers or a small brush.

Step 2 – Test Bearing Function

• Rotate the drum by hand.
• A smooth rotation indicates healthy bearings.
• If the drum resists movement or makes a metallic sound, the bearings may be worn or seized.

Step 3 – Inspect the Bearing Housing

• Look for signs of wear, cracks, or overheating.
• Check that the bearings sit snugly within the housing.
• If the bearings are loose or damaged, they will need replacement.

Replacing the Bearings (If Needed)

Bearing replacement is a more advanced task that requires patience and precision. Follow these steps to ensure a proper fit.

Step 1 – Remove the Old Bearings

• Carefully press the bearings out of their housing with a bearing puller or a flat‑head screwdriver and hammer.
• Take note of the bearing orientation for the new ones.

Step 2 – Clean the Housing

• Wipe the bearing housing with a clean cloth.
• Remove any residue or old lubricant.

Step 3 – Install New Bearings

• Apply a thin layer of machine oil to the new bearings.
• Place them into the housing, matching the orientation of the old bearings.
• Use a hammer gently to tap them into place.

Step 4 – Re‑Fit the Drum

• Slide the drum back into the housing.
• Secure it with the retaining screws you previously removed.

Reassembling the Machine

With the drum, belt, and bearings now in working order, it’s time to put the washing machine back together.

Step 1 – Reattach the Drive Belt

• Ensure the belt sits correctly on both the motor and drum pulleys.
• Tighten the securing bolt or clamp.

Step 2 – Mount the Drum
