Symptoms
- Grinding or scraping sound while the drum moves
- Thumping that matches the drum's rotation
- Squealing that changes with speed
- Noise present even with an empty drum
Likely causes
- CommonForeign object caught between the drum and tubCoins, buttons, or wires can fall through drum holes and rattle or grind during movement.
- CommonWorn agitator dogs or coupling (top-load)Small plastic parts inside the agitator wear down and can cause clunking noises.
- PossibleWorn tub bearingA failing bearing produces a grinding or growling sound, especially during spin.
- PossibleLoose or worn drive belt or pulleyA belt not tracking properly can squeal or slap during operation.
- Less commonUnbalanced load amplifying normal mechanical soundsSometimes a load simply exaggerates sounds that are otherwise minor.
What to do
- Stop the machine and check inside the drum and around the agitator for any visible foreign objects.
- Run an empty cycle to see if the noise persists without a load, which helps rule out object interference.
- On top-loaders, check if the agitator has excessive play or wobble by hand when the machine is off, which suggests worn dogs.
- Listen carefully to note whether the noise happens during wash agitation only, spin only, or both.
- If noise sounds like grinding, especially during spin, this often points to a bearing needing professional inspection.
- Have a technician evaluate belt, pulley, or bearing wear if the source isn't a simple foreign object or agitator part.
