How to tell if washing machine brushes need replacing
Regular maintenance of your washing machine is essential to ensure its optimal performance and longevity. One component that often requires attention is the motor brushes. These small, often overlooked parts play a vital role in allowing the motor to run smoothly and efficiently.
Motor brushes are made of carbon and serve as an electrical conductor, transferring electricity between the stationary and rotating parts of the motor. Over time, these brushes can wear down due to constant friction, reducing their conductivity and causing the motor to malfunction.
However, determining if your washing machine brushes need replacing is not always straightforward. Fortunately, there are a few signs to look out for that can indicate it’s time to replace these essential components.
The first indication of worn-out brushes is excessive sparking from the motor. If you notice flashes or sparks coming from the back of your washing machine while it’s in use, it could be a clear warning sign that the motor brushes are worn down, causing them to lose connection and create high resistance.
Signs of Worn Washing Machine Brushes
Your washing machine relies on brushes to ensure the smooth rotation of the motor and consequently the functioning of the machine. Over time, these brushes can wear out due to regular use. Here are some signs that indicate your washing machine brushes may need replacing:
Inefficient Spinning
If you notice that your washing machine is not spinning as efficiently as it used to, it could be a sign that the motor brushes are worn out. As the brushes become damaged, the spinning motion may become weaker, leading to incomplete or unsatisfactory washing cycles.
Noisy Operation
Worn brushes can cause your washing machine to operate noisily. You may hear unusual sounds, such as grinding or screeching, during the washing or spinning cycle. This noise can be an indication that the brushes are no longer able to provide the necessary electrical connection between the motor and its components, resulting in friction and abnormal sounds.
Visible Wear and Tear
Inspect the brushes for visible signs of wear and tear. Remove the back panel of your washing machine and locate the motor. The brushes are usually attached to the motor and can be identified by their bristle appearance. If the bristles appear significantly shorter or frayed, it is an indication that the brushes are worn and need to be replaced.
Frequent Tripping of Circuit Breakers
If you find that your washing machine frequently trips the circuit breaker, it may be due to faulty or worn brushes. When the brushes are worn out, they may create sparks or increased electrical resistance, causing excess current flow and tripping the breaker. It is essential to address this issue promptly to avoid electrical hazards or further damage to your machine.
Inconsistent Performance
If your washing machine’s performance is inconsistent or unpredictable, it could be a result of worn brushes. The brushes play a vital role in regulating the motor’s speed and overall performance. When they deteriorate, you may experience erratic operation or sudden stops during the washing cycle.

| Noisy Operation |
| Visible Wear and Tear |
| Frequent Tripping of Circuit Breakers |
| Inconsistent Performance |
Unusual Noise during Operation
If you notice any strange, loud, or unusual noises coming from your washing machine during operation, it could indicate that the brushes need to be replaced. Here are some common noises to be aware of:
Clicking or Clanking Noise
If you hear a repetitive clicking or clanking noise, it could indicate that the brushes are worn down unevenly or have become misaligned. This can cause them to make contact with the motor’s commutator at irregular intervals, resulting in the clicking or clanking noise.
Screeching or Squealing Noise
A screeching or squealing noise during operation can be a sign of worn-out brushes. As the brushes wear down, they may not make proper contact with the commutator, causing friction and resulting in the screeching or squealing noise.
If you are experiencing any of these noises, it is recommended to consult your washing machine’s user manual for specific instructions on how to check and replace the brushes. In some cases, you may need to contact a professional technician for assistance.
| Noise | Possible Cause |
|---|---|
| Clicking or Clanking | Worn-down brushes or misalignment |
| Screeching or Squealing | Worn-out brushes |
Inconsistent Spinning
If you notice that your washing machine is not spinning consistently, this could be an indication that the brushes need replacing. Inconsistent spinning can manifest in different ways:
1. Slow or No Spin
If your washing machine is struggling to spin or spinning at a slower speed than usual, worn-out motor brushes could be the culprit. As the motor brushes wear down, they lose their ability to make full contact with the motor’s armature, resulting in reduced speed or even a complete lack of spinning.
2. Intermittent Spinning
Another sign that the brushes need replacing is if the spinning is intermittent. The drum may start spinning and then suddenly stop, or it may spin inconsistently during a wash cycle. This inconsistency can be caused by brushes that are no longer able to maintain a steady and continuous electrical contact with the motor’s armature.
It is important to address these issues promptly, as inconsistent spinning can disrupt the washing process and hinder the machine’s overall performance. Damaged brushes can also place extra strain on other components of the washing machine, leading to further damage if left unresolved. Therefore, if you observe inconsistent spinning, it is advisable to check the motor brushes and replace them if needed.
Poor Electrical Connection
If you have noticed that your washing machine is working intermittently or not functioning at all, it could be due to a poor electrical connection. Over time, the brushes in the motor can become worn out or damaged, resulting in a weak or inconsistent electrical connection.
To check if this is the issue, you will need to access the motor of your washing machine, which is usually located at the bottom or back of the appliance. Carefully remove the access panel or cover and locate the motor. The brushes are small, spring-loaded components that make contact with the motor’s armature and deliver electricity to it.
Inspect the brushes for any signs of wear or damage. They should have a worn-out appearance and be considerably shorter than their original length if they need replacing. Additionally, check for any loose or frayed wires that may be affecting the electrical connection.
If you determine that the washing machine brushes are worn out, they will need to be replaced. Consult your washing machine’s manual or contact the manufacturer for the specific brushes suitable for your model.
Replacing the brushes is usually a straightforward process. However, if you are unsure or uncomfortable doing it yourself, it is recommended to seek professional help or consult a qualified technician.
By regularly inspecting and replacing the brushes when necessary, you can ensure that your washing machine maintains a reliable electrical connection and continues to work efficiently.
Frequent Tripping of Circuit Breakers
If you notice that your washing machine is frequently tripping the circuit breaker in your home, it could be an indication that the brushes need replacing. The brushes in a washing machine are responsible for conducting electric current to the motor. Over time, these brushes can wear down and become less effective. When this happens, the motor has to work harder to complete its tasks, resulting in increased energy consumption and a higher likelihood of tripping the circuit breaker.
To determine if the brushes need replacing, you can perform a simple visual inspection. First, make sure the washing machine is unplugged and disconnected from any power sources. Remove the back panel of the machine to gain access to the motor. Carefully inspect the brushes for any signs of wear or damage. A common sign of worn brushes is a worn-down or significantly shorter length compared to brand new brushes. If you notice any signs of wear, it is likely time to replace the brushes.
In addition to visual inspection, you can also check the motor’s performance. If you notice any unusual noises, such as grinding or sparking sounds, it could indicate that the brushes are worn and not making proper contact with the motor. You may also experience sluggish or inconsistent operation of the washing machine.
Replacing the brushes in a washing machine is a relatively simple task that can usually be done without professional help. However, it is important to consult the manufacturer’s instructions or seek guidance from a professional if you are unsure of the process. When purchasing new brushes, make sure to buy the correct type and size for your specific washing machine model.
Regular maintenance and timely brush replacements can help extend the life of your washing machine and prevent frequent tripping of circuit breakers.
