Washing machines make noise — that's normal. But there's a difference between the ordinary hum of a spin cycle and a sound that signals a part is failing. Since we diagnose noisy washers throughout Bethesda every week, here's a breakdown of what each type of sound usually means.
A grinding sound during the spin cycle almost always points to worn drum bearings or a failing motor coupling. This isn't a problem that improves on its own, and continuing to run the machine can cause additional damage to the drum and tub.
Banging is often caused by an unbalanced load, but if it happens consistently — even with a balanced, smaller load — it usually means a suspension spring or shock absorber has failed and the drum is knocking against the cabinet.
Squealing is a classic sign of a worn drive belt or a motor pulley that needs lubrication. This is typically an inexpensive fix if it's caught early, before the belt fails completely.
If the machine hums but the drum doesn't spin, the motor is receiving power but something downstream — a broken belt, a seized pump, or a failed motor coupling — is preventing movement. Turn the machine off to avoid overheating the motor.
Loose change, buttons, or small items caught in the drum or pump filter are the most common culprits. Check pockets before every load, and clean out the pump filter if your model has an accessible one.
Grinding and persistent banging almost always require a professional diagnosis, since they involve internal components that aren't safe to inspect without disassembling the machine. If your washer is making any of these sounds, call us at (240) 885-0836 and we'll identify the cause before it turns into a bigger repair.
