Diagnosing and Fixing a Noisy Washing Machine
Do you have a noisy washing machine? Did you know that it can turn into a very costly washer repair if you choose to ignore that noise? Unusual sounds are often caused by minor problems such as faulty parts that, if ignored, can develop into major mechanical failures. Understanding which parts make your washing machine noisy can help you address the issue before it worsens.
Drum Bearings
A common cause of noise is when water leaks past the seal and finds its way into the drum bearings. To check for this, first turn off your washing machine and shut off the water supply. Unscrew the back panel and remove the drive belt. Use your hands to spin the drum manually; if you hear a grinding or roaring sound, your drum bearings are failing and need replacement. If it sounds squeaky, you may simply need to use mechanical grease to lubricate the bearing.
Unbalanced Leveling Feet
Loud vibrations or banging noises can be due to an unbalanced machine. Make sure that the leveling feet have firm contact with the floor. To adjust them, undo the locking nuts and unscrew the feet until the machine is completely level. Use a spirit level to ensure accuracy. Once leveled, remember to tighten the locking nuts back into place to prevent them from vibrating loose again.
Tub Bearing and Seals
The tub bearing is mounted in the outer tub at the middle of the clothes washer. It ensures that the inner tub spins smoothly and quietly. Replacing it is an involved affair that requires significant disassembly. In many cases where this bearing is faulty, it is more efficient to replace the bearing and the outer tub as a complete assembly.
Drive Pulley
The drive pulley is the component that the belt rides on to spin the tub. Whether made of metal or plastic, it can become a source of noise if it is cracked, bent, loose, or worn out. Open the washer cabinet to inspect the pulley for any physical defects. If you find damage, get it replaced immediately to prevent the belt from slipping or snapping.
Motor Coupling
This coupling connects the transmission to the drive motor. It can create a loud noise if it is defective or stripped. It is typically made of plastic and rubber and can break if the washing machine is frequently overloaded. Most homeowners find it relatively straightforward to repair a faulty motor coupling once the cabinet is removed.
Washing Machine Clutch
The clutch connects the transmission to the inner wash tub, allowing the machine to gradually reach its proper spin RPM. If the clutch is worn, it can make a loud scraping or howling noise as the washing machine spins. If this is the case, you will need to remove the drive assembly to install a replacement clutch.
You can save a lot of time and money if you check your machine as soon as it starts becoming noisy. If the parts listed above are in good condition, you may also need to check the drain pump, shock absorbers, or suspension springs.
If your unit is making excessive noise during high-speed turns, you may need help diagnosing spin cycle failures. For more appliance diagnostic insights, visit our main resource page.
