Washer-dryer combo produces a high-pitched squeal or grinding noise when spinning or tumbling.

Safety first: Disconnect power before spinning the drum by hand or removing panels.

• Manual spin test: Rotate the drum by hand. Listen for grinding or scraping and feel for roughness. Persistent noise suggests bearing or pulley issues.
• Inspect belt and pulley: Remove the rear panel. Check the drive belt for glazing or fraying and the drum pulley for looseness or wobble. Tighten pulley bolt and replace belt if worn.
• Check for trapped objects: Shine a light through the drum holes and around the door gasket area to look for bra wires, coins, or screws rubbing the tub. Remove any foreign objects.
• Bearing replacement: If noise is clearly from the rear bearing area and there is drum play, the rear tub and bearing assembly likely needs replacement, which is a complex repair often best handled by a professional.
