Replacing Carbon Brushes in a Washing Machine

Carbon brushes are the part of the motor designed to come in contact with the moving part to pass power through. This means, after time, they do wear down and will need to be replaced. Signs that could mean your carbon brushes need replacing are; Your machine is filling and draining per usual, but not turning/ Spitting or spluttering sounds coming from your machine/ Sparks coming from the underneath of the machine.

Let's Get Fixing[edit]

Get Access[edit]

First, you will need access to the back of your machine. It’s advised to disconnect your washing machine and move it somewhere you have plenty of space, this will reduce some of the stress of your repair task without having to be crammed up trying to see what you’re doing.


Remove Top and Back Panel[edit]

You will need to remove the top lid and back panel to reveal the back of the machine drum, the drive belt and the motor that should be situated underneath the drum.


Removing the Motor[edit]

Carefully remove your drive belt, and any wires connected to your motor. Use a socket spanner to then release the motor. Then, once removed, you should easily be able to easily replace the carbon brushes.

NB: some machines do allow you to replace the carbon brushes without removing the motor. Check the user manual to see if this is possible. However, if you like more space to work, it may be easier to still remove the motor so you can easily see what you are doing.


Locating the Carbon Brushes[edit]

You will find the carbon brushes situated on either side of the motor, pointing in towards the commutator. It is important to note that the carbon brushes are actually inserted at an angle, which is why the bottom edge of the brush is slanted so that the commutator can smoothly glide along. It is very important to insert the brushes in the correct position. It is easiest to do this by taking note of the position of your old carbon brushes when removing them. Then you can simply replace your new carbon brushes the same way.


Replacing the Carbon Brushes[edit]

To replace the carbon brushes, simply remove the old ones by taking off the clip and taking out the pin, gently pull out the spring followed by the carbon brush itself (remember to look which way it was facing!). Then, simply replace it with your new one by gently inserting the carbon brush, pushing in the spring afterwards (which may be fiddly but stick with it) and then re-secure the pin and clip to keep it all in place.


Almost Done[edit]

Once this is done, you can simply replace all the components back in the machine (don’t forget anything!) and your motor will once again be running smoothly.

Comments[edit]

Why replace them on your own? Quite simply, it could save you an expensive bill from an electrician. It could also be faster than having to wait for an appointment slot. The procedure is quick and simple, and will leave you feeling accomplished having repaired your washing machine back to tip top condition.
