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

Safety first: Unplug the unit before spinning the drum by hand or removing panels.

• Manual drum test: Spin the drum by hand from the front. Listen for grinding or scraping. Check for vertical or lateral play by lifting the drum.
• Inspect rear pulley and belt: Remove the rear panel and check the drum pulley and belt. Tighten the pulley bolt and replace a damaged pulley or belt.
• Check for foreign objects: Shine a flashlight through drum holes to look for bra wires or small objects rubbing the tub. Remove if visible.
• Bearing replacement: If noise persists and there is noticeable play, the tub bearings are likely worn. Bearing replacement is complex and usually requires tub disassembly by a professional.
