Quick answer

If your washer won't agitate, first check the lid switch and water level. Ensure the machine is getting power and the load is balanced. If these don't work, inspect the motor coupling or transmission.

Confirm the symptom

Washer fills with water but doesn't agitate
Drum spins during spin cycle but not during wash
No agitation noise during wash cycle
Washer works fine in spin cycle but not wash

Tools and prep

Screwdrivers (flathead and Phillips)
Multimeter for testing electrical components
Flashlight for visibility
Work gloves for safety
Bucket for water collection
Turn off power at the circuit breaker
Turn off water supply valves

Step-by-step troubleshooting

Check Lid Switch
Do: Inspect the lid switch for damage or wear. Test continuity with a multimeter.
Observe: Lid switch is broken or not making contact.
Means: Replace the lid switch.
Next: If the lid switch is working, move to the next step.
Verify Water Level
Do: Check if the washer is filling to the correct level. Ensure the water inlet valves are open.
Observe: Washer is not filling properly or is overfilled.
Means: Adjust or replace water inlet valves.
Next: If water level is correct, proceed to the next step.
Check Power Supply
Do: Ensure the washer is plugged in and the circuit breaker hasn't tripped.
Observe: Power is not reaching the washer.
Means: Reset the circuit breaker or check the power cord.
Next: If power is confirmed, continue to the next step.
Inspect Load Balance
Do: Check if the load is evenly distributed in the drum.
Observe: Load is uneven or too heavy.
Means: Redistribute or reduce the load.
Next: If load is balanced, move on to the next step.
Test Motor Coupling
Do: Access the motor coupling and check for damage or wear.
Observe: Motor coupling is broken or worn out.
Means: Replace the motor coupling.
Next: If motor coupling is intact, check the next component.
Examine Transmission
Do: Inspect the transmission for signs of wear or damage.
Observe: Transmission is faulty or worn.
Means: Replace the transmission.
Next: If transmission is working, consult a professional.

Common causes

Cause	Likelihood	Difficulty	Part often needed
Faulty Lid Switch The lid switch prevents the washer from agitating if the lid is open or not properly closed.	Common	Easy	Lid Switch
Incorrect Water Level Improper water levels can prevent the washer from starting the agitation cycle.	Sometimes	Easy	Water Inlet Valve
Power Supply Issues A tripped circuit breaker or faulty power cord can cut power to the washer.	Sometimes	Easy	Power Cord
Unbalanced Load An uneven or overly heavy load can prevent the washer from agitating properly.	Sometimes	Easy	None
Broken Motor Coupling The motor coupling connects the motor to the transmission and can wear out over time.	Common	Medium	Motor Coupling
Faulty Transmission A worn or damaged transmission can prevent the drum from agitating.	Sometimes	Hard	Transmission

FAQ

Can a faulty lid switch cause the washer not to agitate?

Yes, a faulty lid switch can prevent the washer from agitating because it signals the washer that the lid is open.

How do I know if the motor coupling is broken?

A broken motor coupling may show signs of wear, cracks, or complete disconnection between the motor and transmission.

Is it safe to replace the transmission myself?

Replacing the transmission can be complex and may require specialized tools. It's recommended to call a professional unless you have experience with appliance repairs.

Why is my washer filling with water but not agitating?

This could be due to a faulty lid switch, incorrect water level, or a problem with the motor or transmission.
