F21 Code on Whirlpool Washer: Quick Troubleshooting Guide

A Whirlpool washer displaying an F21 error code indicates a draining problem. This error arises when the washing machine cannot drain water within a certain timeframe, typically eight minutes. Homeowners confront this issue when the washer’s drainage system is hindered by a blockage or a malfunctioning component. Addressing this error promptly is crucial to resume the normal operation of the appliance.

Resolving the F21 code typically involves checking for and clearing blockages in the washer’s drain hose or filter. Additionally, inspecting the drain pump for any obstructions or failures may be necessary. Regular maintenance of the washing machine can prevent the occurrence of this error by ensuring that the components involved in the drainage process are clean and functional.

If the problem persists after the preliminary checks and cleaning, further investigation into the washer’s internal parts may be required. Professional repair or replacement of parts such as the drain pump, pressure switch, or control board might be needed to rectify the drainage issue and clear the F21 error code.

Understanding F21 Error Code on Whirlpool Washers

When an F21 error code appears on a Whirlpool washer, it typically indicates a drainage problem that prevents the machine from completing a cycle. Understanding this error can help users troubleshoot effectively.

Causes of F21 Error

Drainage Path Obstructions: A primary cause of the F21 error code is an obstruction within the washer’s drainage path. This may include:

• Clogged drain pump filter: A small garment, lint, or debris buildup.
• Blocked drain hose: Kinks or clogs from accumulated fabric, lint, or foreign objects.

Pump Problems: Faulty components within the drain pump can also trigger the F21 code. These faults may involve:

• Malfunctioning pump motor: Unable to effectively move water out.
• Broken impeller: Compromised water flow due to damaged parts.

Interpreting Error Codes

Whirlpool washer error codes like F21 are specific diagnostic tools for identifying particular issues. They can often be deciphered by referring to the owner’s manual or the manufacturer’s guide available here.

When addressing error codes, it is important to consider:

• Context of the Error: Assessing when the F21 code appears during the wash cycle provides clues about the specific drainage issue.
• Frequency of the Error: If the F21 code occurs consistently, it likely indicates a persistent drainage complication requiring immediate attention.

Troubleshooting the F21 Error

Inspecting the Drain Hose

First, check the drain hose for blockages and ensure it’s not kinked. The hose should be disconnected from the back of the washer to look for any foreign objects or debris. If any clogs are present, they should be removed to allow for free water flow.

Checking the Drain Pump Functionality

Next, inspect the drain pump for functionality issues. It is essential to look for blockages in the pump filter, a common spot where coins and small items can get trapped. A multimeter can be used to test for continuity. If the pump lacks continuity, it needs to be replaced.

Examining the Pressure Switch

Finally, the pressure switch must be examined as it is critical for monitoring water levels. Disconnecting the switch and using a multimeter to test its operation for continuity can help ensure it’s working correctly. A lack of continuity indicates a need for replacement.

DIY Solutions for Clearing F21 Error

Cleaning the Drain Pump Filter

To address blockages in the drain pump filter, which can lead to the F21 error, you’ll want to start by locating the filter at the bottom front of your washer. The drain pump filter should be carefully removed and cleaned, often hidden behind a small access panel.

First, place a bucket underneath to catch any water, then slowly remove the filter by turning it counterclockwise. Remove any obstructions you find and rinse the filter thoroughly before reinserting it.

Unclogging the Drain System

If cleaning the drain pump filter doesn’t resolve the F21 error, the issue might be in the drain system. Use a plumber’s snake to unclog any noticeable blockages in the drain hose.

Ensure that the hose is not kinked or obstructed, and check that the clamp securing the hose is tight and secure. The problem may be further along in the household drainage system if the drain hose is clear.

Verifying and Repairing Electrical Connections

A less common cause of the F21 error could be a problem with the electrical wiring or wiring harness connected to the pump or control panel. Verify that all connections are secure and that the harness has no visible damage. If the wiring is intact, yet the problem persists, it may indicate the need for a deeper electrical diagnosis, which might require professional assistance.

Maintenance Tips to Prevent F21 Errors

Regular Washer Care and Inspections

One should regularly check the washer for any obstructions in the drain system. This includes inspecting the drain hose and the pump filter for blockages. For Whirlpool washers, adhering to the manufacturer’s instructions on cleaning the pump filter is crucial. For example, a manual for Whirlpool washers emphasizes the importance of safety messages and underscores that service and maintenance should be performed by a Whirlpool designated service.

The washer should be on a flat surface to avoid errors. It is also recommended to run a cleaning cycle monthly, using either a commercial washer cleaner or a homemade solution of vinegar and baking soda to keep the washer in optimal condition.

Appropriate Load Sizes and Detergent Use

Excessive suds can cause F21 errors due to suds reducing the efficiency of the drain system. Using an appropriate high-efficiency (HE) detergent that corresponds to the load size is important. Adequate spacing in the washer allows water and detergent to be distributed evenly among clothes, essential for proper cleaning and rinsing. A Whirlpool washer manual suggests ensuring the washer is not overloaded, as excessive loading can strain the motor and affect drainage.

When to Seek Professional Help

When preventive maintenance does not resolve recurrent F21 errors, it may be time to seek professional assistance. Users should consult with a qualified technician who is familiar with Whirlpool washers. It is imperative that safety precautions are taken and that servicing is not attempted by individuals without proper expertise. A technician will assess if a deeper issue with the washer’s hardware hinders the drain cycle.

Resetting and Restarting After an F21 Error

Steps to Reset the Washer

The initial step in resetting the Whirlpool washer is to pause or cancel the wash cycle. One should press the pause/cancel button twice and, in models that require it, press the “Power” button once to cancel the cycle fully. If the washer does not respond, unplugging it from the power source allows it to reset. Wait a minute before reconnecting the washer to ensure the control board has fully reset. This action helps restore the washer’s efficiency by clearing any existing errors.

How to Restart the Wash Cycle

After successfully resetting the washer, one can restart the wash cycle by selecting the desired cycle and pressing the “Start” button. It is critical to ensure the water level is appropriate for the load to prevent further malfunctions.

Observing the washer’s operation during the initial stages of the restart can help confirm that the issue has been resolved. If the F21 error code persists, further troubleshooting or professional assistance might be required, as the error can indicate a more serious underlying issue.
