If you’re ready to do a load of laundry and your washing machine just hums, you’re probably a little stressed out right now. No doubt this is a less-than-ideal situation, but that buzzing noise you hear may not be as severe as it seems.

There are several possible reasons why your washing machine is humming but not working. Usually, it can be repaired, and it doesn’t have to be expensive. At the very least, the repair cost of your machine will be less than if you have to buy a replacement. Here are some possible reasons why your washing machine hums but won’t start.

If your washing machine makes a humming noise but doesn't start, it may indicate problems such as a malfunctioning motor, a broken belt, or issues with the control board. To troubleshoot, ensure there are no blockages in the drum and that the door is firmly shut. Check the power supply and try resetting the machine. It's best to get help from a qualified expert for an accurate diagnosis and repair if the issue continues.

Below, you will find comprehensive information that may be helpful in your current situation.

Why Is Your Washing Machine Making a Humming Noise?

Life can get pretty hectic. The typical family has so much on their plate that we rely on everything running smoothly to keep up with our busy schedules. When a washing machine is humming but not spinning, it's one of those issues that can really throw a spanner in the works and disrupt our daily routine.

There are some things you can’t fix yourself without help, but sometimes, there may be a simple fix for your washer that you can take care of yourself. Let’s take a look at some of the common causes of a washing machine that’s humming but won’t start.

Clogged or Damaged Drain Hose

For a washing machine to function properly, it requires a consistent flow of water entering and exiting it. Any disruption in this supply and drainage system can lead to issues, such as the washing machine humming but not draining. If you observe this sound and the machine appears to be still operational, the likely culprit is a defective drain hose. Simply replacing the hose should resolve the issue without requiring professional repair assistance.

Water Flow Issues in the Washing Machine

If your hose is fine and the humming seems to be related to the fact that your machine isn’t filling with water, then you may have a more serious issue, such as a plumbing problem. 

The first thing you should do is check that the taps that feed your machine are fully open. If they are and there is still no water flowing, try unhooking the feed hose and running it into a sink to see if the water is actually flowing. If you notice that the water flow is slow or that there isn’t any, there’s a good chance you have a plumbing issue.

Washer Drain Pump Blockage or Damage

While modern washing machines are designed to protect the moving parts in your machine from damage, sometimes, something does get past these safeguards. Occasionally, a small particle from a pocket or a small piece of clothing can work its way into the washing machine pump. Higher-end machines may display an error code on the control panel to indicate this, but many machines don’t. The only way to know for sure is to take the machine apart to access the pump. Unless you’re confident in your DIY skills, it’s probably best to call Spark Service PRO at that point for professional help.

Faulty or Damaged Drive Motor

If the humming noise you hear when using the washer is accompanied by the smell of something burning, there may be a major problem with your machine. That burnt smell is probably coming from your motor, and it likely needs to be replaced. This isn’t an easy fix, and it’s probably best to contact a repair company at that point.

Damaged Motor Coupling Can Stop the Wash Cycle

Another possible cause of your washing machine emitting a humming or buzzing noise could be a damaged motor coupling. This component links your machine to the pump and is essential for the washer's operation. Repairing this issue typically demands a considerable level of expertise, and it's often advisable to entrust this task to professionals who provide washing machine repair service as well.

How to Fix a Washing Machine That Just Hums

If you’ve taken a close look at your machine and you’ve ruled out everything you can think of, it’s a good idea to call a licensed repair person for help. Just be sure to check the hoses and look for anything obvious that may be blocking the regular operation of your machine before you do.

Spark Service PRO has years of experience helping homeowners identify the root cause of broken appliances. Our team is fully certified and ready to serve you promptly. We aim to get your appliances back up and running at the least possible cost to you. Keeping this in mind, our initial focus is on exploring straightforward solutions that might be elusive to those without specialized knowledge. Here are some typical examples.

Blocked Pump Preventing Washer from Draining

Sometimes, a piece of loose clothing can get lodged in the washing machine pump. Although there may not be any actual damage to the pump itself, the humming noise you hear is likely due to the piece of clothing preventing the pump from turning.

Loose Motor Coupling Causing Washer Malfunction

Our washing machines are true workhorses. The average household tackles laundry duties at least once a week, if not more frequently. With all that heavy usage, it's no surprise that the internal components can take a beating. Sometimes, parts can become loose, causing the machine to malfunction.

That buzzing sound might be something as straightforward as a loose connection between the motor coupling and the pump. When our technician arrives, they'll inspect for any loose fittings. If that's indeed the issue, they'll promptly tighten everything up, getting your laundry routine back on track in no time.
