Washer-dryer combo produces a loud grinding or rumbling noise during spin.

Safety first: Unplug the unit. Bearing replacement involves significant disassembly; consider professional service.

• 1. Spin drum by hand: With the door open, rotate the drum. A rough, grinding feel or metallic scraping indicates bearing issues.
• 2. Check for drum play: Lift the front of the drum up and down. Excessive movement suggests worn bearings or spider arm.
• 3. Inspect rear of tub: Remove the rear panel and look for rust streaks or water trails from the bearing area.
• 4. Plan for major repair: Replacing bearings usually requires splitting the outer tub and may involve replacing the entire rear tub assembly or drum and spider. This is a complex repair often best left to a technician.
