How to Fix / Troubleshooting
Safety first: Unplug the appliance before removing the rear panel.
- Inspect belt and pulleys: Remove the rear panel and check the belt for glazing, cracks, or contamination. Clean pulleys and replace the belt if worn.
- Check pulley alignment: Ensure the drum pulley is tight and runs true. Tighten the center bolt if loose.
