Common causes

Cause	Likelihood	Difficulty	Part often needed
Faulty Lid Switch Prevents the washer from starting the wash cycle if the lid is not properly closed.	Common	Easy	Lid Switch
Broken Motor Coupling Connects the motor to the transmission; if broken, the motor can't transfer power to the agitator.	Common	Easy	Motor Coupling
Worn Transmission Internal components wear out over time, causing noise and failure to agitate.	Sometimes	Hard	Transmission
Damaged Drive Belt A broken or loose belt can prevent the agitator from moving and cause noise.	Sometimes	Easy	Drive Belt
Faulty Motor A malfunctioning motor can't provide the necessary power for the wash cycle.	Rare	Medium	Motor
Foreign Objects Items stuck in the drum or under the washer can cause noise and prevent proper operation.	Sometimes	Easy	N/A

FAQ

Why is my washer making noise but not agitating?

This is often caused by a broken motor coupling, faulty lid switch, or worn transmission. Check these components for damage.

Can I fix a noisy washer myself?

Yes, for common issues like a faulty lid switch or broken motor coupling. For complex problems like transmission failure, consider a professional.

How do I know if the motor is bad?

If the washer makes a humming noise but doesn't spin or agitate, the motor may be faulty. Test it with a multimeter for continuity.

What tools do I need to replace a lid switch?

You'll need screwdrivers, a multimeter, and safety goggles. Ensure the washer is unplugged before starting.

Why won't my washer agitate in one direction only?

This is typically due to a worn transmission or a problem with the motor's direction control.
