Washing Machine Making Humming Noise

Introduction

Is your washing machine humming like a busy bee, but not actually washing? A humming noise, instead of the usual whirring and splashing, is a common problem that indicates something isn’t quite right. This usually means that something is preventing the motor from turning freely. Ignoring it can lead to more serious issues, like a burnt-out motor or damaged parts. Let’s get that hum silenced and your clothes clean!

Common Causes of washing machine making humming noise

Here are some of the most frequent culprits behind that annoying humming sound:

Overloaded Washing Machine: Too many clothes crammed inside can strain the motor, leading to a hum.
Blocked Drain Pump: Lint, coins, or other small items can clog the drain pump, preventing it from working.
Foreign Object Obstruction: Socks, underwear, or other small items might be stuck between the inner and outer tubs.
Worn-Out Drive Belt: In belt-driven machines, a worn or broken belt can cause a humming noise as it struggles to turn the drum.
Faulty Motor: The motor itself might be failing, causing it to hum instead of spin properly.
Stuck or Damaged Pump Impeller: The impeller is what actually pumps the water out. Damage or a blockage here can cause a hum.
Worn Motor Coupler (Direct Drive Machines): The motor coupler connects the motor to the transmission. If it is worn or broken it can cause a humming.
Bad Motor Start Capacitor: The capacitor helps start the motor. A failing capacitor will cause a humming noise.

Symptoms Checklist

Use this checklist to pinpoint the problem:

Does the washing machine hum when you turn it on, but the drum doesn’t spin?
Does the humming noise get louder when the machine tries to drain?
Is there water left in the drum after the wash cycle?
Did you recently wash something bulky or that could have shed lint (like a new towel)?
Does the machine smell burnt? (If so, unplug it immediately and call a technician)
Is your machine a direct drive type with no belt visible?

How to Fix washing machine making humming noise Step-by-Step Guide

Here’s a step-by-step guide to troubleshooting that humming noise:

Unplug the Washing Machine: Safety first! Disconnect the power cord from the outlet.
Check for Overloading: Remove some items from the drum to see if it spins more freely. Restart the cycle.
Inspect the Drain Hose: Make sure the drain hose isn’t kinked or clogged. Straighten it if necessary.
Locate the Drain Pump: This is usually located at the bottom front or back of the machine. Consult your owner’s manual.
Access the Drain Pump: Many machines have an access panel you can remove. You may need a screwdriver.
Clean the Drain Pump Filter: Carefully remove the filter and clean out any lint, coins, or other debris. Be prepared for some water to spill.
Inspect the Drain Pump Impeller: Check if the impeller (the fan-like part inside the pump) is damaged or obstructed. Try to spin it manually. It should move freely.
Check for Objects Between Tubs: Shine a flashlight between the inner and outer tubs. You might see a sock or other small item lodged there. (This may require disassembling parts, so consider calling a technician if you aren’t comfortable.)
Inspect the Drive Belt (if applicable): If your machine has a belt, check for wear, cracks, or breaks. If it seems loose, it might need replacement.
Check Motor Coupler(if applicable): Check the motor coupler for wear or breakage. It is located between the motor and transmission.
Check Motor Start Capacitor: (If applicable) If you have some electrical knowledge, check the motor start capacitor. Consult your manual for location and instructions.
Plug the Washing Machine Back In: After checking the above, plug the machine back in.
Run a Test Cycle: Start a short wash cycle to see if the humming noise is gone.
Monitor the Machine: Observe the machine during the cycle to ensure it’s functioning properly.
Call a Technician: If the humming persists after these steps, it’s time to call a qualified appliance repair technician.

Fix the Issue Without Buying Parts

Before resorting to replacements, try these free methods:

Reset the Washing Machine: Unplug the machine for 1-2 minutes, then plug it back in. This can sometimes reset the electronic controls.
Clean the Washing Machine: Run an empty cycle with a washing machine cleaner or a cup of white vinegar to remove buildup.
Check Leveling: Make sure the washing machine is level. Uneven leveling can cause vibrations and noise.
Inspect Hoses: Check the water inlet and drain hoses for kinks or blockages.
Ensure Proper Voltage: Use an independent circuit to avoid voltage drops that will make the motor hum.

When Replacement Might Be Necessary

If the humming noise persists after trying all the above steps, a replacement part might be needed. Common culprits include:

Drain Pump: $50-$150 (USD)
Drive Belt: $20-$50 (USD)
Motor: $150-$400 (USD)
Motor Coupler: $20-$40 (USD)
Motor Start Capacitor: $15-$30 (USD)

If you’re not comfortable replacing parts yourself, it’s best to call a technician.

Safety Warning

Always unplug the washing machine before attempting any repairs.
Avoid working on electrical components if you’re not comfortable with electricity.
Be careful when handling water, as it can create a slip hazard. Clean up any spills immediately.
If you smell a burning odor, unplug the machine immediately and call a technician.

Tools You May Need

Screwdrivers (Phillips and flathead)
Pliers
Flashlight
Towels
Bucket
Multimeter (for checking capacitor)
