Washer making humming noise usually means one part of the machine is powered and trying to do its job, but the cycle is not moving ahead the way it should.
If your washer is making a humming noise, the sound may happen during fill, drain, startup, or when the machine tries to move into wash or spin. In some cases, the hum is brief and harmless. In others, the washer hums repeatedly while failing to move forward properly.
Why Is My Washer Making Humming Noise?
A washer making humming noise is often dealing with a drain issue, water-fill problem, a pump or valve trying to work, a load-related stall, or a cycle condition that the washer cannot complete smoothly.

Quick Answer: Why a Washer Is Making a Humming Noise
A washer usually makes a humming noise because one part of the machine is powered and trying to do its job, but the cycle is not moving ahead the way it should. The most common reasons are a pump trying to drain through a restriction, a fill-side issue, or a transition where the washer is energized but not progressing properly.
In many cases, the hum is not the actual failure. It is the sound of the washer trying to perform a step and struggling to complete it.
Most Common Reasons a Washer Is Making a Humming Noise
- Drain pump humming against blockage
- Washer trying to fill but water is not entering normally
- Object caught in the drain path or pump area
- Cycle transition problem near startup or spin
- Load-related stall in some cases
- Repeated retry behavior during the cycle
If the washer is also draining poorly, start with Washer Won’t Drain. If the humming happens when the cycle should begin filling, also compare it with Washer Not Filling With Water.
When the Humming Noise Happens Matters
The stage where the sound appears can help narrow the cause:
- During drain: often pump blockage or slow drainage
- During fill: often weak water supply or fill-side issue
- At startup: often lock, sensing, or early-cycle transition
- Before spin: often drain completion or stage-transition issue
You do not always need to identify the exact internal part first. You mainly need to determine which stage keeps producing the humming sound.
What to Check First When a Washer Is Making a Humming Noise
1. Check whether the sound happens during drain
If the hum appears while water is being removed, the drain pump or drain path is one of the first things to suspect.
2. Check whether water is entering normally
If the washer hums near the beginning and little or no water enters, the fill side may be the real issue.
3. Watch whether the cycle actually progresses
If the washer hums briefly and then runs normally, it may be part of normal operation. If it keeps humming and does not continue, that matters more.
4. Check for related symptoms
If the washer also pauses, stops, leaves water behind, or fails to start, the humming is likely part of that larger problem.
How to Fix a Washer That Is Making a Humming Noise
Most humming-noise problems should be approached by checking drain and fill behavior first before assuming a major internal failure.
Inspect the drain path if the humming is during drain
If the sound appears while the washer is removing water, compare the issue with Washer Won’t Drain, Washer Not Draining Completely, or Washer Not Draining But Still Spins.
Check water supply if the humming is during fill
If the washer hums near startup and water is not entering correctly, compare the problem with Washer Not Filling With Water.
Retest with a simple cycle
After checking the obvious issue, run a basic cycle and listen for whether the humming returns in the same stage.
Compare startup behavior if needed
If the washer hums but does not really begin the cycle, compare the issue with Washer Won’t Start or Washer Starts Then Stops.
When the Drain Pump Is the Real Cause
Many humming-noise problems are really pump problems.
Possible signs include:
- The humming sound appears mainly during drain
- The washer also drains slowly or incompletely
- Water remains in the drum after the cycle
- The same humming happens every time water should leave the machine
In those cases, compare the issue with Washer Won’t Drain, Washer Won’t Drain or Spin, and Washer Drains But Won’t Spin.
When Fill Problems Are the Real Cause
If the humming happens near startup and the machine does not take in water normally, the issue may be on the fill side instead.
Possible signs include:
- The washer hums but no water enters
- The machine pauses early in the cycle
- The same problem happens every cycle
- The washer never gets into a normal wash rhythm
In those cases, compare the issue with Washer Fills Then Stops, Washer Won’t Fill or Spin, and Washer Won’t Start But Has Power.
How to Reset a Washer After a Humming Noise Problem
Once you have checked the obvious drain, fill, and cycle conditions, a simple reset may help the washer run normally again.
- Turn the washer off
- Unplug it from the power source
- Wait about 5 minutes
- Plug it back in
- Run a short test cycle
A reset can clear a temporary interruption, but it will not permanently fix repeated blockage, weak fill, or pump-related problems.
Is It Serious If a Washer Is Making a Humming Noise?
Sometimes yes. A repeated humming sound often means the washer is trying to perform a function and not succeeding normally. That is usually more important than a brief one-time hum.
It becomes more serious when:
- The humming gets louder or more frequent over time
- The washer also drains poorly or fails to fill
- The same sound happens every cycle
- The machine also pauses, stops, or leaves clothes wet
- A reset does not help
When to Call a Technician
You may need professional service if:
- The washer keeps making a humming sound after basic checks
- The same noise happens every cycle
- You suspect a severe pump, fill, or control-related issue
- The machine behaves the same way after reset
At that point, the problem is more likely to involve internal pump, fill, or control components than a simple user-side issue.
FAQ
Why is my washer making a humming noise?
The most common reasons are a pump struggling against blockage, a fill-side issue, or a repeated cycle transition problem.
Can a drain pump make a humming noise?
Yes. A pump can hum when it is energized but struggling to move water through a blockage or restriction.
Can a washer hum if water is not entering?
Yes. Some washers hum near the fill stage when they are trying to move forward but water is not entering properly.
Will unplugging the washer fix a humming-noise problem?
Only if the issue was a temporary interruption. A reset will not fix repeated pump, blockage, or fill-related problems.
Final Thoughts
If your washer is making a humming noise, start with the basics first: pay attention to when the sound happens, check whether the washer drains properly, make sure water can enter normally, and test a short cycle. In many cases, the noise is not random. It is tied to one specific stage that the washer is struggling to complete.
If the problem keeps coming back, the washer may have a pump, fill-side, or control-related issue that needs closer diagnosis. Move next to Washer Won’t Drain, Washer Not Filling With Water, or Washer Making Buzzing Noise depending on when the humming sound happens.
