How to Fix / Troubleshooting

Safety first: Unplug the washer. Sharp edges and heavy components are present when accessing the drum.

  • Step 1 – Spin drum by hand: With the machine off, rotate the drum manually. Listen for grinding or roughness and feel for play by lifting the drum up and down.
  • Step 2 – Check for foreign objects: Look through the drum holes with a flashlight for coins or bra wires rubbing the tub. Remove via the heater opening if accessible.
  • Step 3 – Inspect belt and pulley: Remove the rear panel. Check the belt for glazing or fraying and ensure the drum pulley is tight. Replace the belt if worn.
  • Step 4 – Bearing assessment: If noise persists and there is noticeable drum play or brown rust streaks at the rear of the tub, the bearings and seal are likely failing. Bearing replacement usually requires tub disassembly and is best done by a professional.
