Washing machine carbon brushes (also called motor brushes) are small carbon blocks that deliver electrical current to the motor’s rotating armature via the commutator. In brushed motors (common in many older and mid-range washers), they wear down over time due to constant friction—typically lasting 5–10 years depending on usage. When broken, worn, chipped, or no longer making proper contact, they cause distinct symptoms. Recognizing these early prevents motor damage or complete failure. The most common and obvious sign is the drum failing to turn. The machine fills with water normally, agitates weakly or not at all, sits idle during wash/spin …
