Tumble Dryer Is Making A Grinding Noise

Like all electrical appliances your tumble dryer can be susceptible to the occasional problem or fault, and a grinding noise is one of the most common. Here are a few of the most common causes.

Metal objects

A possible reason for your tumble dryer making a grinding sound is because there’s a metal object hitting the sides of the drum. Stop the machine and check for coins, keys, belt buckles or screws and take them out. The best advice is to check all your pockets BEFORE you put your clothes in the dryer.

Worn rollers

The rollers are a small set of (usually metal) wheels attached to the exterior of the drum that help it spin. If they start to wear it can cause a grinding noise when the drum turns. Replacing the worn rollers for new ones should sort out the problem.

Disintegrating gliders

On some tumble dryers the drum’s outer rim is a pair of gliders which act as a protective barrier to prevent the rim coming into direct contact with the metal cabinet when the drum spins. They’re usually a thin seal made of nylon or plastic, depending on your dryer model. They wear down over time, resulting in a grinding or whining noise. To stop these noises you’ll need to replace them (they’re sold as a pair so it’s best to replace them both so they wear evenly).

Slipped belt

There’s a long, thick rubber belt that encompasses the centre of the drum which supports it and allows it to rotate. If the belt slips from its position it could start making a grinding noise because it’s trying to maintain its position as the drum spins. See how to replace your tumble dryer belt above.

Damaged tensioner

The tensioner (or idler pulley) keeps the belt firmly positioned on the drum, and the belt goes over the component’s bracket which is attached to a wheel and spring. When the wheel malfunctions it can result in a grinding noise because it’s struggling to turn and maintain the belt’s tension. Damage can also occur because there’s a lack of sufficient tension.
