A noisy washer can indicate something as simple as an unbalanced load or a metal buckle from clothing hitting the drum when washing, or else a more serious problem from a defective washer part. Determining the causes behind a noisy washer might take some time and some parts that are causing the noise are incredibly time-consuming to reach and replace. Here are some things you can check and some parts that might be causing noise from your washing machine.
One simple thing you can do is run your washer without anything inside (so an empty load). This will allow you to listen to the appliance at work. It might also indicate that the problem is not with your washer, but with a particular load of laundry. However, if you do notice an unusual noise, try to take note at what part of the cycle you hear it as this might give you a clue as to what part could be causing the noise.
While your washer is off and empty, spin the tub or drum by hand. If you hear a lot of noise or there is a lot of back and forth wobbling movement, this might indicate a problem with the drum’s support parts or bearing.
Drain pump or pump and motor assembly
Noise during or after the spin cycle could indicate a problem with the drain pump or pump and motor assembly (depending on your model). The drain pump pumps the water out the machine before and during the spin cycle. Sometimes objects can become lodged in the drain pump, causing noise from a restriction. You will have to take apart the machine to reach the pump to check for obstructions and possible replace the pump.
Both top-loader and front loader washers can have belts connecting them to a drive motor (drive belt) or transmission, depending on your machine. Over time the belt can become worn, crack and lose pieces, causing noise when the machine is running and indicating that the belt needs to be replaced.
Drive Pulley and pulley
If you have a belt-driven washing machine, a worn drive pulley or pulley can cause a loud squealing noise when the motor is running. You will need to remove a cabinet panel to access the drive or other pulleys that hold the belt in place. Inspect the pulleys and replace if the part is worn or defective.
Parts that support the washer drum
Banging sounds and shaking during the spin cycle might be caused by broken or worn parts that support the tub. Manually spin the tub of your machine while it is not in use and listen for any noises while it spins. Also take note if the tub is leaning or tilting to one side. Washer support parts that might be causing noise include:
Broken suspension rods or suspension springs, which support the tub, could be reason behind a noisy washer, especially when it’s in use. If the tub appears crooked inside the machine, it could indicate one of the rods or spring has broken.
Shock absorbers support the tub while the washer is running. Worn shock absorbers could be the reason your washer is noisier than normal.
Both front and top loading washer have bearings that allow the inner tub to spin smoothly when in use. Normal wear and tear from use or overloading the basket can cause the bearings to go bad; leading to noise that might increase over time. You will need to replace the bearing and possibly a seal as well. Be sure to also inspect the outer tub for holes, as it can become damaged as well, so it might too need to be replaced. Since the bearing sits in the middle of the washer, it is difficult to reach and requires disassembling most of the washer. It might be easier just to replace the entire outer tub and bearing.
These are just a few of the parts that could be causing noise during your washer’s cycle. Other parts that could be causing noise also include the water inlet valve, motor, agitator dogs and clutch assembly.
