How often should agitator dogs be replaced?

Agitator dogs typically wear out over time due to normal use. Their lifespan depends on washing frequency and load sizes. They should be replaced when symptoms of failure, such as the agitator not moving clothes effectively, become apparent. There is no fixed replacement schedule.

Can I replace agitator dogs myself?

It involves disassembling the agitator to access and swap out the small plastic or rubber parts. Basic tools are usually sufficient, and detailed guides are widely available to assist with the process.

What causes agitator dogs to fail?

Agitator dogs fail primarily due to wear and tear from repeated engagement and disengagement during wash cycles. Overloading the washer, washing very heavy items, or frequent use can accelerate this wear. Once worn, they lose their ability to properly engage the agitator's one-way clutch mechanism.
