Repair A Carbon Brush

Repair A Carbon Brush


Washing machine motor brushes – or carbon brushes – work to conduct electricity in your washing machine from the fixed to the moving parts. The moving motor part is the armature, and the brush works in contact with a specific part called the commutator.


Because these brushes are constantly working in contact with the moving motor parts, they tend to wear down over time. However, they are quite easy to replace. You’ll know when it’s time to do so, because your washing machine’s motor will start to run intermittently or half-heartedly. Other symptoms include sparks, or total non-operation!


Before you replace the part, make sure the washing machine is switched off at the wall. Then, use a screwdriver to remove the top and side machine panels, before taking the back off. Once you do this, you’ll see the motor, located under the drum. Some models actually allow you to replace the brush without moving the motor.


If, however, you do need to remove your motor, simply take off the drive belt, and then remove the connecting wires. Use a socket spanner to loosen the connecting nuts, and you’ll be able to pull the motor away. Make sure you replace the new brushes at the right angle, and ensure that they don’t get caught on the side. It can be a bit fiddly, so persevere! You may want to replace both brushes at the same time – it is good practice to do so to maintain the ‘balance’. Once they’re in place, simply repeat the previous steps in reverse.
