Grinding or rumbling noise during wash or spin, increasing over time.

Safety first: Unplug the unit before any internal inspection. Sharp edges and heavy components are present.

Steps to evaluate:

• Spin drum by hand: With the door open, rotate the drum slowly. Listen for grinding or roughness and feel for play (wobble) indicating bearing wear.
• Check pulley and belt: Remove the rear panel and inspect the drive pulley and belt. Tighten pulley bolt and replace a worn or glazed belt.
• Inspect for leaks: Look for water or rust streaks around the rear tub bearing area, which indicate seal failure.
• Assess repair scope: Replacing rear tub bearings on a GE Profile UltraFast combo typically requires replacing the entire rear tub assembly and transferring components. This is a complex repair.

Due to the extensive disassembly required, tub bearing replacement is usually a job for an experienced technician.
