5 Reasons Your Washing Machine Is Making That Whirring Noise

A washing machine is supposed to make some noise—but when a strange whirring sound shows up, it can leave you wondering if a breakdown is on the way. While some causes are harmless, others may signal the need for repair or part replacement. Ignoring the noise could lead to bigger issues and more costly fixes. Fortunately, identifying the reason behind the whirring can help you decide whether it’s a quick fix or time to call a professional. Here are five common reasons your washing machine is making that unsettling whirring sound. Understanding the cause is the first step toward a quieter, more efficient laundry day.
1. Worn Drive Belt
A worn drive belt is one of the most common causes of a whirring sound during the spin cycle. Over time, this rubber component can stretch, crack, or fray due to constant tension and friction. As the belt wears down, it may start to slip, producing a fast-paced whirring noise. The sound often gets louder as the drum speeds up or slows down. If left unchecked, a broken belt can stop the washer from spinning entirely. Replacing the belt is typically inexpensive and can restore the washer’s quiet operation.
2. Faulty Motor Bearings
Motor bearings are responsible for helping the drum rotate smoothly during each cycle. When they begin to fail, they create a noticeable whirring or grinding noise that worsens over time. The sound usually comes from the bottom or rear of the machine. Water exposure or general wear and tear can damage these components. Unfortunately, replacing motor bearings can be labor-intensive and may require a full motor replacement. If your machine is older, it may be more cost-effective to replace the unit rather than repair it.
3. Foreign Object in the Drum or Pump
Loose coins, small toys, or buttons can easily get trapped between the drum and the tub or end up in the pump. These objects can cause a high-pitched whirring as they spin or rub against moving parts. The sound may come and go depending on the position of the object during the wash cycle. If left alone, the debris could damage the pump or cause clogging. Running your hand around the drum and checking the pump filter can help spot and remove the culprit. Regularly emptying pockets before washing can prevent this issue altogether.
4. Malfunctioning Pump Motor
The pump motor is responsible for draining water out of the machine, and when it malfunctions, it often creates a loud whirring sound. You might notice the sound during the drain or spin cycle when the pump is most active. If the motor is struggling, water may not drain properly, leading to standing water in the drum. Dirt, lint, or fabric threads can clog the pump and overwork the motor. In some cases, the entire pump assembly may need to be replaced. A noisy pump motor should be addressed quickly to avoid total failure.
5. Imbalanced Load
An imbalanced load can create a whirring or vibrating noise as the washer struggles to distribute weight evenly. This usually happens when you wash a single large item, like a blanket or towel, without adding smaller items to balance it out. As the drum spins, the uneven weight distribution causes it to wobble and make noise. Over time, repeated imbalance can damage the drum bearings or suspension system. Most machines will automatically try to correct the imbalance but may still emit a loud sound. Rebalancing the load and distributing items more evenly can stop the noise instantly.
Don’t Ignore the Whirring—Investigate It
A whirring noise from your washing machine isn’t something to brush off—it’s often a warning sign of wear, obstruction, or imbalance. Catching the issue early can save you from more extensive (and expensive) repairs down the line. Whether it’s a simple belt swap or a deeper motor problem, understanding the cause puts you in control. Regular maintenance, like checking for foreign objects and balancing your loads, can extend your washer’s lifespan. If DIY fixes don’t solve the issue, a trusted appliance technician can help pinpoint and repair the problem. Either way, taking action now ensures your laundry room stays efficient—and a lot quieter.
