Reasons Why Washer Makes Noise
Pump & Pump Motor
The drain pump has the function of pumping water from the washing tub and throughout the spin cycle. It may be belt-driven, motor-driven, or has its engine. If you hear the noise while spinning, the drain pump is most likely damaged.
The drive belt links the gearbox and the drive engine (on top-load washer) or connects the basket to the drive engine (on front-load washer).
This part is normally manufactured as a sole V-shaped or multi-ribbed belt with rubber-coated fabric. However, the V-belt prevents slipping well with the washer on load, while the rubber-wrapped belt with pulley helps reduce friction when starting the washer.
When this belt is overloaded, it will result in wear and damage. It cannot lower the friction in the drive motor and the transmission. The more collisions you have, the more likely your drive belts will damage the entire engine and cause unbearable noise.
The Direct-Drive Motor Coupler
The direct-drive engine coupling on several modern load-washers is used to transfer energy from the engine to the gearbox (transmission). It helps to connect the engine to the transmission. It features two elastic drive forks and a rubber coupling.
Two plastic discs are linked with the drive shaft end. One of the transmission forks was connected to the motor shaft.
Next, the rubber coupling absorbs the spring torque to avoid cracking forks while the motor shaft spins. However, abrasion on the collar through repeated use often causes the drive disc to slip and generate vibrations and noise.
On the other hand, whether the gearbox gets stuck or the basket does not rotate freely, a faulty coupling can also boost the noise and shatter the house’s quiet space.
Most front-load washers are equipped with shock absorbers to reduce tub movement during the rotate cycle. These shock absorbers are linked to the base frame as well as the outer tub. When this absorber is attenuated or defective, there is usually a loud bang during the washing process. In this case, you need to fix it early, or else it will damage other parts.
Tub Dampening Strap
For several most reliable load washing machines, tub dampening straps are used to buffer the tub movement during the rotate cycle. Generally, there will be four straps linked to four corners and the tub of the washer cabinet, helping the cycle work quieter.
They are produced by rubber, so they are easily damaged over time. When the belt is stretched or destroyed, the tub will be rubbed against the washer cabinet throughout the turning cycle, creating a loud thump.
The drive motor operates the transmission, turns the basket and possibly the pump. A fairly common symptom towards front-load washers, the drive motor that operates the belt (which drives the basket pulley) is damaged. This often makes a buzzing noise or hum, often escorted by a burning odor.
When the motor is thermally overloaded, the windings will lose the power, the motor turns off, and some parts of the engine become stuck, causing noise owing to the impact.
Drive Motor Pulley
For a belt-driven washer, the drive motor pulley assists the serpentine belt (can be the pump belt). The actuator and pump also have corresponding pulleys. These pulleys often accumulate many grease, rubber compounds, or dirt, which will create a strong thumping sound during the engine’s running.
In the event of a malfunction of this motor pulley, you will hear a lot of noise while the engine is stirring, draining, or turning.
The pump belt is the pulley drive on the discharge pump. Over time, the press belts may turn into broken or frayed. This creates a noisy process during the rotation or drain, accompanied by the smell of burning rubber or dripping gutter.
The tub bearing allows the inner tub or the basket to spin freely. In fact, front-load washing machines usually have two bearings for basket shaft supporting. These two ones are positioned at the outer tub’s rear.
Normally, bearings have a tub seal to prevent water and detergent that can damage them. Nevertheless, overuse and heavy contact with detergent and overload states will result in bearing failure.
The bucket and the tub cannot normally rotate at that time, causing a collision and noise. Mention the rusted tub bearing, it also makes every little rubbing and causes unnecessary noise.
Agitator Directional Cogs and Dogs
The washer agitator directional cogs, or agitation dog, can operate a double-acting stirrer. Some cam-shaped dogs have built-in cogs on the inside stirrer when it spins without changing the direction and releases it again when the stirrers reverse.
These gears are produced by solid plastic and will corrode over time. At that time, they will begin slipping and making a scratchy sound. Because when they are too worn, they can no longer attach the gears to the stirrer tightly.
The part is usually installed in top-load washers. It locks the transmission shaft to the washer basket throughout the spinning cycle.
Time to time, repeated friction between clutch gaskets rubbing against the cover may cause the entire clutch assembly to wear out and make noise. When the clutch has malfunctioned, you can easily figure out the shavings found under the washer makes a noise or a burning smell during the spin cycle.
Besides, the clutch might prevent the washer from turning at the correct speed when being worn.
How to Make a Washing Machine Quieter?
The above shows the basic reasons for washer noise. Anyway, you need to take these instructions below to overcome the annoyances caused by this noise thoroughly.
Inspect And Repair The Pump & Pump Motor
You have to unplug the washer in advance, then remove the panel or front washing cabinet to locate the pump.
After that, you carry on plugging in the washer again and running the test to verify if the pump is making noise. Use caution when you are in contact with electrical circuits.
If the pump is broken, remove the hose into the pump. Whether the impeller gets any noise by foreign objects or damaged signs, you discard it at once. Otherwise, if there are signs of wear or tear, you replace the pump motor.
If The Drive Belt Needs Substituting
First, disconnect the power source. Then you remove the front panel or front cabinet. You can verify the drive belt which is interconnected with the drive motor.
Next, remove the straps holding the belt and remove the belt to check out. Finally, inspect the drive belts for signs of damage, burning, or wear. If needed, replace them immediately for safety spin cycles.
Check Out Direct Drive Motor Coupling
First, you also need to unplug the power from the washing machine. Then, open the washer cabinet, locate and remove the direct drive motor coupling. It is up to the machine’s model, you may need to take off the drain pump and motor instead to access the drive motor coupling.
Examine if these joints are cracked, worn, or damaged and replace another one in case of need.
Inspect Shock Absorbers
To inspect shock absorbers, do the following:
- Disconnect power first, next you eliminate the front panel to locate the shock absorbers.
- You then check out the vibrations to determine if the dampers are damaged, have liquid leaks, or are weakened.
- If one of the shock absorbers is out of date, you will need a replacement set. Since both have the same rate of wear and damage, you ought to alter both for sure.
Examine Tub Dampening Strap
After disconnecting the power, you open the washer cabinet. Now, it’s time to position the four dampening straps. Check if they are worn or damaged, wear, or frayed among these four straps to replace if necessary.
It is advisable that you change all straps simultaneously as they wear at more or less the same rate.
How to Test Drive Motor
Ensure you have disconnected the washer’s power, then remove the washer and locate the drive motor. Next, you unplug and remove it from the washing machine.
With the multimeter watch set to Rx1, check continuity by placing the probes on one end of each. You will get a value of 0 or close to 0.
You then go on testing the ground connection, one probe end is still touching the ground, the other is touched to the bare metal housing of the motor. If you get different results, you have to change a new one at once.
You must disconnect the power supply before starting the test. Then, remove the cabinet and position the pulley, and remove the pulley belt.
If there are signs of burning, damage, or abrasion, you need to replace the pulley. On the other hand, if they are greasy, dirt accumulates, you should clean the surrounding area or anything you find out on the pulley at once.
Check Pump Belt
After unplugging, you open the washing cabinet to place this belt connected with a drive motor pulley one on end. You continue removing the clamps holding the belt to check if you see any signs of wear, damage, burning, or fraying then replace it instantly.
Inspect The Tub Bearing
Disconnect the power, and then you take off the washer cabinet in order to locate the tub bearing. Besides, other types of washing machines need to remove the inner tub, the washing basket, and the transmission to feed the tub bearing.
Next, check the bearings for rust, wear, and damage. If one of the above marks appears, replace them. But it is recommended that you alter the tub seal as well, which limits water and detergent from damaging the new tub bearings.
Examine Agitator Cogs
Here are some steps to examine agitator cogs:
- Of course, disconnecting the power from the washer is the first thing to do.
- Next, you open the washer’s lid and take off the fabric softener drawer to position the cogs. Alternatively, you can also remove the agitator’s top to easier position the cogs, depending on the washer’s model.
- Finally, you check for signs of damage, wear, discoloration in the cogs, and if necessary, you replace other agitator cogs.
Examine Clutch Assembly
Unplug first, then you locate the clutch assembly (positioned beneath the outer tub with the attachment of the basket drive assembly) and then remove them to check.
How to remove the clutch assembly? Yes, it forces you to have to disassemble the washing cabinet, as well as the drive motor and even the transmission assembly. If there is any indication of damage, burning, or wear, please replace another one.
