Why is my Whirlpool washer not agitating in the wash cycle?

If your Whirlpool washing machine isn’t agitating properly during the wash cycle, there are a few likely causes you can check and troubleshoot yourself before calling a repair technician.

Common Causes of a Whirlpool Washer Not Agitating

Here are some of the most common reasons a Whirlpool washing machine won’t agitate and tips to try yourself to get the washer agitating again:

Faulty Lid Switch

The lid switch is a safety device that prevents the washer from agitating when the lid is open. If the lid switch is defective, the washer may not agitate even when the lid is closed properly.

Try tapping on the lid switch a few times to see if the washer begins agitating. If the tap works temporarily, it usually means the lid switch needs replacing.

Worn Agitator Dogs

The agitator dogs are plastic components attached to the agitator that cause the back-and-forth motion that cleans the clothes. After years of use, these dogs can become worn and prevent the agitator from moving properly.

Inspect the agitator dogs to see if any look worn down. Replacing the agitator dogs is an easy DIY fix that should get the washer agitating again.

Damaged Agitator

If the agitator itself is damaged due to hitting it against laundry or other objects, it may not be able to move freely. Visually inspect the agitator for any cracks or damage. If damage is found, replacement of the agitator is recommended.

Faulty Agitator Coupling Kit

The coupling kit connects the motor to the agitator. If this coupling kit is worn out or damaged, the motor may still run but not engage the agitator. Replacing a faulty coupling kit is the solution in this scenario.

Defective Water Inlet Valve

The water inlet valve controls the flow of water into the washer tub. If this valve malfunctions, it may not allow enough water into the tub for proper agitation. Inspect the inlet valve for any blockages or damage. Replacing the valve may be needed if an issue is found.

Clogged Water Pump Filter

A clogged pump filter can prevent proper water flow and lead to lack of agitation. Clean out the filter to clear any debris, lint, coins, etc. Trapped in the pump.

Faulty Motor Control Board

The motor control board controls the motor and agitation functions. If this component malfunctions, it can stop the motor from running or prevent the agitator from moving. Replacing a defective control board may be required.

Damaged Drive Belt

The drive belt connects the motor to the wash basket. If this belt is loose, worn or broken, it can cause lack of agitation issues. Inspect the belt and replace if damaged.

How to Diagnose the Exact Problem

To pinpoint exactly which part is causing your Whirlpool washer to not agitate, follow these troubleshooting steps:

Check if the washer is getting power – Is it plugged in? Check breakers/fuses.
Check the lid switch – Tap it a few times while the washer is running.

Inspect the drive belt – Is it loose or broken? Tighten or replace if needed.
Examine the agitator parts – Look for worn or damaged agitator dogs, coupling kit or agitator itself. Replace any defective parts.
Test the motor separately – Run a Spin Only cycle to test the motor. If it works, focus on agitator components.

Check water flow – Make sure water inlet valve is functioning and pump filter is clear of debris.
Inspect control board – Check for loose connections or burned spots indicating short circuit.
Consider a faulty position switch – This provides feedback to control board on basket position.

Going through these steps methodically will help you determine what needs to be repaired or replaced to get your Whirlpool washer agitating properly again.

How to Fix a Whirlpool Washer Not Agitating

Once you’ve diagnosed the specific cause of the no agitate problem, here are tips for completing the repair yourself or deciding if you need professional help:

Replace Lid Switch

Replacing a faulty lid switch is relatively easy. Locate the switch on top of the washer frame and disconnect the wires. Remove any screws or clips and lift off the old switch. Install the new switch, reconnect wires, and test operation.

Change Agitator Dogs

First remove the cap/softener dispenser at the top of the agitator. Then lift off the upper agitator portion to access the dogs underneath. Pop off the old dogs and press new ones into place. Reassemble agitator and test.

Replace Agitator

Removing the agitator usually requires an agitator puller tool to grip and lift it off the shaft. Installation is the reverse, but be sure the agitator is fully seated and secured. Apply downward pressure while starting a cycle to ensure it engages.

Replace Coupling Kit

The coupling kit is attached to the underside of the agitator. Removing the agitator provides access. Disconnect the coupling from the transmission drive shaft. Install new coupling, reconnect, and confirm proper operation.

Clean Pump Filter

The pump filter is located at the bottom front of the washer. Turn off power, disconnect hoses, and unscrew the filter to clean out debris. Reassemble, confirm no leaks, and test operation.

Replace Inlet Valve

Shut off hot and cold water supply lines before replacing inlet valve. Detach hoses, remove mounting screws, and disconnect wiring. Install new valve, reconnect, and check for leaks and proper operation.

Replace Motor Control Board

This requires extensive disassembly to access the control board. Unless you are very mechanically skilled, it is best left to a professional technician to diagnose and replace the motor control board.

Replace Drive Belt

The drive belt is located at the back. Remove rear panel, loosen motor mounts, and lift belt off pulleys. Loop new belt around pulleys, tighten motor mounts, and test operation in a spin cycle prior to reinstalling panels.

Troubleshooting Tips

Here are some additional tips that can help troubleshoot and fix a Whirlpool washer not agitating:

Check error codes – Any flashed error codes can indicate problems with motor, position sensor, control board, etc.

Listen for humming – If motor hums but washer won’t agitate, focus on agitator or coupler.
Remove extra weight – Overloading can cause lack of agitation.
Ensure washer is level – Improper leveling can inhibit agitation.

Test with empty tub – Eliminates load size as possible culprit.
Plug into separate outlet – Avoid using an extension cord which may impact performance.
Check hoses for leaks – Small leaks can sidetrack proper agitation.

Clean mineral buildup – Heavy limescale or debris deposits may obstruct agitation.

When to Call a Repair Professional

While many agitation issues are DIY-friendly fixes, there are instances when it’s best to have a trained appliance repair technician handle the repair:

Diagnosing unknown electrical issues or complex control board problems

Accessing and replacing drive motors, pumps, or gearcases
Extensive disassembly of cabinets, tubs, drums, etc. required for repair
Any major component replacements – transmission, clutch, stator, rotor

If attempted repairs are unsuccessful and problem persists
For warranty service repairs within the covered timeframe
Any repairs posing safety risks if done incorrectly

Many Whirlpool washer repairs are within the capabilities of do-it-yourselfers. But there’s no shame in seeking professional assistance for repairs that are too complex, unsafe, or simply outside your comfort zone.
