Understanding the Problem
A grinding or humming noise coming from a washing machine usually means a mechanical component is rubbing, jammed, or struggling to turn. Grinding is commonly caused by worn tub bearings, a foreign object caught between the drum and tub, or debris in the drain pump. Humming often indicates the motor is trying to start but can’t spin freely — this can be the motor itself, a seized pump, a failed motor coupling, or a worn belt slipping under load. How you diagnose the problem depends on when the noise occurs. If the sound happens during spin it’s often bearings, drum wobble, or belt/drive issues. If it occurs during drain it’s usually the drain pump or trapped debris. If the machine hums but doesn’t agitate or spin, suspect a motor start problem, motor coupling, or a jammed pump. Always unplug the machine before inspecting internal parts and check simple things first (filter/pump area, visible debris) before replacing major components.
Common Symptoms
Loud grinding during spin, metallic scraping when drum turns, steady humming with no or slow drum movement, intermittent noise only during drain, drum wobble or leaking near the tub area.
Common Causes
- Foreign object or debris stuck in the drain pump or between drum and tub
- Worn tub bearings or a failing bearing/seal assembly causing metal-on-metal contact
- Failed motor coupling, worn belt, or motor start issue causing the motor to hum but not turn

Helpful Repair Tip
To confirm the faulty part, run a short spin/drain cycle with an empty drum and listen closely at the front and bottom of the washer. Use a long screwdriver pressed to the cabinet touching different areas (drum, pump housing, motor) to localize the vibration — the screwhole acts like a stethoscope.
Frequently Asked Questions
My washer hums but the drum doesn't spin — is that the motor?
A humming motor can mean the motor is trying to start but is blocked or the start mechanism has failed. Before replacing the motor, check for a jammed drain pump, a broken motor coupling (common on Whirlpool-style machines), and a seized drum bearing. If those are clear and the motor still only hums, the motor or start device may need replacement.
Can I fix grinding/humming myself or do I need a technician?
You can diagnose and fix some issues yourself—remove and inspect the drain pump for debris, check the filter, run an empty spin to localize the noise, and visually inspect belts and couplings. Replacing tub bearings or motors is more advanced (requires drum removal and specialized tools) and is usually best handled by a technician unless you’re comfortable with major appliance disassembly.
