Washer-dryer combo drum does not turn during wash or dry, but you can hear the motor running or humming.

Safety first: Unplug the unit before removing the rear panel or touching the belt.

Step-by-step checks:

• 1. Access the belt: Remove the rear panel to expose the drive belt and pulleys.
• 2. Inspect the belt: If the belt is off or broken, remove it completely. Check for signs of wear, glazing, or stretching.
• 3. Check pulleys: Ensure the motor pulley and drum pulley are secure and aligned. Tighten any loose mounting bolts.
• 4. Install new belt: Fit an OEM Monogram drive belt around the motor pulley first, then roll it onto the drum pulley while rotating the drum by hand.
• 5. Test operation: Reinstall the rear panel, restore power, and run a short cycle to confirm the drum turns smoothly.

When to call a technician: If the new belt quickly comes off again, there may be underlying alignment or bearing issues requiring professional service.
