Washer makes loud squeaking or grinding sounds during the wash or spin cycle — caused by a worn or seized idler pulley bearing no longer rotating freely.
The washer drum fails to spin or agitate properly because a damaged idler pulley cannot maintain adequate tension on the drive belt.
The drive belt repeatedly slips off or derails from the pulley groove due to a cracked wheel rim or worn pulley surface that no longer guides the belt correctly.
A stalled idler pulley causes the drive belt to rub and generate friction heat, producing a distinctive burning rubber smell during spin.




💡 Pro Tip: How to Tell Your Idler Pulley Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Squeaking or grinding noises during the wash or spin cycle
⚠️ Washer drum not spinning or agitating properly
⚠️ Drive belt slipping off or coming loose repeatedly
⚠️ Burning rubber smell — caused by the stalled pulley rubbing the moving belt
🔍 Quick diagnosis: Remove the lower front panel and shine a flashlight on the idler pulley during the spin cycle. If the pulley wheel intermittently stops spinning while the belt keeps moving, or if you see visible cracks on the wheel rim, it's time to replace it. Always unplug the washer before attempting any inspection or repair.
