What causes a Whirlpool washer not to agitate?

Quick Answers

There are several common reasons a Whirlpool washer won’t agitate:

• The lid switch is defective
• The motor coupler is broken
• The drive belt is worn or broken
• The shifter kit is defective
• The actuator is defective
• There is a wire, component, or power failure

Diagnosing the specific cause requires checking each component and part individually. The issue will likely require replacing a part like the lid switch, coupler, belt, shifter kit, or actuator. Replacing wires or components may be needed for electrical issues.

Common Causes of a Whirlpool Washer Not Agitating

When a Whirlpool washer won’t agitate, the issue typically lies with one of the following components:

Lid Switch

The lid switch is a safety device that prevents the washer from running when the lid is open. If the switch fails, it can prevent the agitator from working properly. The switch is activated when the lid is closed. If the switch malfunctions, it will disable agitation. Replacing a faulty lid switch will typically resolve the problem.

Motor Coupler

The motor coupler connects the drive motor to the gear case. It allows the motor to engage the gear case and spin the agitator. If the coupler breaks, the motor will still run but the agitation motion will stop. Replacing a broken coupler is the solution in this scenario.

Drive Belt

The drive belt transfers power from the motor to the agitator. If the belt becomes excessively worn or breaks altogether, the motor will run but the agitator won’t move. Replacing a damaged drive belt will restore normal agitation function.

Shifter Kit

The shifter kit actuates the gear case to switch the washer between agitate and spin cycles. A defective shifter kit can prevent the agitator from engaging. Replacing the entire shifter assembly corrects this problem.

Actuator

The actuator is the motor that controls the gear case. If the actuator fails, the washing cycles will not function properly or at all. This commonly prevents agitation. The fix is to replace the actuator.

Electrical Issues

Electrical failures can also prevent the agitator from working. For example, a wire may have failed or come loose. Components like timers, control boards, and relays may malfunction. Testing the electrical system and replacing damaged wires or parts will resolve these types of issues.

How to Diagnose the Exact Cause

To determine the exact reason a Whirlpool washer is not agitating, you’ll need to diagnose the issue methodically:

1. Confirm the washer is getting power. Check for lights on the console. Listen for sounds when selecting a cycle. If there are no signs of power, check the power cord, outlet, and electrical connections.
2. Inspect the lid switch. Use a multimeter to test it while operating the washer. Replace it if defective.
3. Examine the motor coupler. Look for cracks or breaks. Replace the coupler if damaged.
4. Check the condition of the drive belt. Replace if loose, warped, cracked, or broken.
5. Test the shifter and actuator using a multimeter. Determine if they are functional electrically. Replace any defective components.
6. Assess the control board and other electronics. Check for error codes. Use a multimeter to test components. Replace electronics as needed.
7. Inspect wires and connections. Ensure no wires are loose, worn, or disconnected. Secure any loose connections.

Going through these troubleshooting steps methodically will reveal the root cause of the agitation problem. Once identified, replacing the specific defective part will resolve the issue.

Replacing Parts to Fix Agitator Problems

When diagnosing the agitator issue, you’ll need to replace any parts found defective. Here are some tips for replacing common Whirlpool washer components:

Lid Switch

• Unplug the washer before starting.
• Pry off the console to access internal components.
• Detach the wire harness from the switch.
• Release the switch from the mounting bracket.
• Install the new switch by reversing these steps.

Motor Coupler

• Unplug the power cord and turn off water supply lines.
• Remove the console panel to access the coupler.
• Take off the drive belt.
• Detach the coupler halves from the motor and gear case shaft.
• Attach the new coupler and reassemble components.

Drive Belt

• Start by turning off power and water to the washer.
• Tilt the washer back to access the bottom panel.
• Remove the panel to reveal the belt.
• Take a photo of the belt routing path before removing.
• Roll the belt off the pulleys and remove it from the washer.
• Loop the new belt around the pulleys as shown in the photo.

Shifter Kit

• Unplug the washer and turn off water lines.
• Take off the console panel.
• Disconnect wires from the shifter.
• Remove mounting screws to detach the shifter.
• Install the new shifter kit and reconnect wires.

Actuator

• Start by disconnecting power and water to the washer.
• Remove the console panel.
• Detach the actuator wires.
• Take out mounting screws to remove the actuator.
• Install the new actuator and reconnect wires.

Carefully following the proper steps to remove and replace parts can help ensure the repair is successful. Take photographs along the way to assist with correct reassembly.

Electrical Failures

For electrical failures, you’ll need to methodically test components using a multimeter. Check for continuity through wires and test parts for proper ohm readings. Here are some tips for diagnosing and fixing electrical issues:

• Check error codes on the display for clues about failed components.
• Inspect all wiring for damage. Replace any worn or disconnected wires.
• Remove and test the control board with a multimeter. Replace if defective.
• Check key parts like the timer, lid switch, actuator, and motor. Replace if faulty.
• Ensure all wire harnesses and connections are secure.
• Test power outlets and inspect the power cord. Replace defective parts.

Electrical problems can be tricky to resolve. Carefully check each component systematically until the source is found.

Getting Professional Assistance

While the agitator issue may be repairable yourself, it’s best to contact a professional appliance repair technician if:

• You are uncomfortable performing electrical testing or part replacement.
• The diagnostics involve major disassembly of the washer.
• There are multiple failed parts needing replacement.
• The exact problem cannot be identified.
• Safety issues or risks are a concern.

Professional technicians have specialized skills, tools, and experience. They can properly diagnose complex issues and safely conduct repairs. Only contact a factory authorized servicer when possible.

Cost to Repair a Whirlpool Washer Without Agitation

The repair cost typically ranges from $200-$400 for a Whirlpool washer with agitator problems. Here are some average price estimates:

Part	Repair Cost
Lid switch	$120
Motor coupler	$150
Drive belt	$100
Shifter kit	$200
Actuator	$350

Add $50-$100 for professional diagnostic fees. Complex electrical issues will be toward the higher end. Getting an accurate repair quote requires proper diagnosis of the specific failed part.

How to Prevent Washer Agitator Problems

You can help prevent agitator problems through proper care and maintenance:

• Avoid overloading the washer, which strains components.
• Level the washer properly to prevent vibration damage.
• Leave the lid open when not in use so moisture can evaporate.
• Use gentle cycles for delicate fabrics to reduce strain.
• Clean the washer interior regularly with affresh tablets.
• Use only HE (high-efficiency) detergent to prevent suds buildup.
• Clean the door gasket regularly to avoid mold and mildew.

Routine maintenance helps keep all mechanical and electrical components functioning properly. Immediately attending to any issues as they arise also helps prevent bigger problems down the road.

Conclusion

A Whirlpool washer not agitating properly is often due to a failed lid switch, motor coupler, drive belt, shifter kit, or actuator. Electrical problems can also prevent the agitator from working. Diagnosing the specific faulty component is needed for a proper repair. Replacement parts typically range from $100-$350, plus any labor fees for professional service. With some effort and the right parts, many do-it-yourselfers can repair Whirlpool agitator issues at home. But for complex repairs, contacting an appliance service technician is advised. Consistent maintenance and care is key for minimizing washer problems over time.
