Whirlpool Washer Making Buzzing Noise

Quick answer

A buzzing noise from your Whirlpool washer is often caused by a faulty lid switch, motor issues, or a loose component. Turn off the power, check the lid switch, and inspect for loose parts before replacing any damaged components.

Confirm the symptom

• Buzzing noise during or after the cycle
• Noise only when the washer is running
• No spinning or agitation when buzzing occurs

Tools and prep

• Screwdrivers (flathead and Phillips)
• Multimeter for testing electrical components
• Work gloves
• Flashlight
• Owner’s manual for reference
• Turn off power at the circuit breaker

Step-by-step troubleshooting

1. Check the Lid Switch
   Do: Inspect the lid switch for damage or wear. Use a multimeter to test continuity when the lid is closed.
   Observe: If the switch is broken or has no continuity, it won’t allow the motor to run properly.
   Means: A faulty lid switch can prevent the washer from operating correctly, causing buzzing.
   Next: Replace the lid switch if it’s faulty.
2. Inspect the Motor
   Do: Listen closely to determine if the buzzing is coming from the motor area. Check for any visible damage or overheating.
   Observe: A humming motor that doesn’t spin may indicate a failed motor or motor coupling.
   Means: A seized or damaged motor can cause buzzing without movement.
   Next: Test the motor with a multimeter or replace it if damaged.
3. Check for Loose Components
   Do: Look for loose or vibrating parts, such as the agitator, drum, or internal components.
   Observe: Loose parts can create buzzing or rattling noises during operation.
   Means: Secure or replace any loose components to eliminate the noise.
   Next: Tighten or replace as needed.
4. Examine the Drive Belt
   Do: Check the drive belt for signs of wear, cracking, or looseness.
   Observe: A worn or loose belt may slip or buzz during operation.
   Means: A damaged belt can cause unusual noises and improper motor function.
   Next: Replace the drive belt if it’s worn or damaged.
5. Test the Water Inlet Valve
   Do: Check the water inlet valve for mineral buildup or blockage.
   Observe: A clogged valve may cause buzzing when water is being drawn in.
   Means: A blocked valve can restrict water flow and create noise.
   Next: Clean or replace the water inlet valve if necessary.
6. Check the Leveling Feet
   Do: Ensure the washer is level and the leveling feet are secure.
   Observe: An unlevel washer may vibrate or buzz during operation.
   Means: Improper leveling can cause the washer to rock or buzz.
   Next: Adjust the leveling feet to stabilize the washer.
