What Does the F21 Error Code Mean on Your Maytag Washer?

If you own a Maytag washer and encounter the F21 error code, it’s a clear indication that your washing machine is experiencing a drainage issue. This error typically arises when the washer takes longer than expected to drain water from the drum. Understanding the root cause and knowing how to resolve it can save you time and money, and potentially avoid a costly service call. This article will delve into what the F21 error means, the possible reasons behind it, and step-by-step instructions to troubleshoot and fix the issue.

What Does the F21 Error Code Signify?

The F21 error code on a Maytag washer is associated with a drainage problem. It occurs when the washing machine’s control system detects that water is not draining out within the expected time frame, which is usually around 8 minutes. When this happens, the washer pauses its cycle to prevent water overflow and potential damage to the appliance.

Several issues could lead to the F21 error, including a clogged drain hose, a blocked pump filter, or a malfunctioning drain pump. Recognizing these potential causes is essential for effectively resolving the problem.

Common Causes of the F21 Error Code

1. Clogged Drain Hose: The drain hose is responsible for carrying wastewater out of the washer. Over time, it can become clogged with debris such as lint, soap residue, or foreign objects like coins and buttons. A clogged drain hose restricts water flow, triggering the F21 error.

2. Blocked Pump Filter: The pump filter prevents debris from entering the drain pump. However, if the filter becomes obstructed, water cannot pass through, causing drainage issues.

3. Faulty Drain Pump: A malfunctioning or damaged drain pump can prevent water from being pumped out of the washer effectively. This could be due to electrical failure or physical blockages within the pump itself.

4. Kinks or Blockages in the Drain Hose: If the drain hose is bent, pinched, or improperly installed, it can hinder water flow and result in the F21 error.

5. Improper Installation of the Drain Hose: If the drain hose is positioned too high or too low, it can affect the washer’s ability to drain water efficiently. Manufacturers usually recommend a specific height for optimal performance.

How to Troubleshoot and Fix the F21 Error Code

If your Maytag washer displays the F21 error code, follow these steps to identify and resolve the problem:

Step 1: Pause and Reset the Washer

• Turn off the washer and unplug it from the power source.

• Wait for 5-10 minutes to allow the system to reset.

• Plug the washer back in and restart the cycle. If the error persists, proceed to the next step.

Step 2: Check the Drain Hose

• Inspect the drain hose for any visible blockages or kinks.

• Remove the hose from the washer and run water through it to ensure it’s clear of debris.

• Reattach the hose, ensuring it is properly positioned according to the manufacturer’s guidelines.

Step 3: Clean the Pump Filter

• Locate the pump filter, typically found behind an access panel at the bottom front of the washer.

• Place a towel or shallow pan beneath the filter to catch any residual water.

• Unscrew the filter cap and remove it. Clean out any debris, lint, or foreign objects.

• Reinsert the filter and secure the cap tightly.

Step 4: Inspect the Drain Pump

• Access the drain pump by removing the washer’s rear or bottom panel.

• Check for blockages or obstructions in the pump and its impeller.

• If the pump is damaged or fails to operate, consider replacing it.

Step 5: Verify Proper Installation

• Ensure the drain hose is positioned at the correct height (typically 36-96 inches from the floor).

• Check for any bends or improper connections that may restrict water flow.

Step 6: Run a Test Cycle

• Once all components are inspected and cleaned, run a short wash cycle to test if the F21 error has been resolved.

Preventive Measures to Avoid the F21 Error Code

To minimize the chances of encountering the F21 error in the future, consider these preventive tips:

1. Regular Maintenance: Periodically clean the pump filter and check the drain hose for blockages.

2. Avoid Overloading: Overloading the washer can strain the drainage system and lead to clogs.

3. Inspect Pockets: Always check clothing pockets for small items like coins, keys, and tissues before loading the washer.

4. Use the Right Detergent: Use high-efficiency (HE) detergent to prevent excessive suds, which can contribute to drainage issues.

5. Monitor Installation: Ensure the drain hose is installed correctly and meets the manufacturer’s height requirements.

When to Call a Professional
