Owning a Whirlpool top-loading washing machine comes with the convenience of efficient laundry cleaning, but it also requires regular maintenance to keep it performing at its best. One critical component that often goes unnoticed until problems arise is the drain pump filter. This small yet essential part is designed to trap debris—like lint, hair, and small objects—preventing them from clogging the drainage system. When neglected, a clogged filter can lead to drainage issues, unpleasant odors, or even lint residue on your clothes, especially noticeable on dark fabrics. Fortunately, cleaning the filter on a Whirlpool top loader is a straightforward task once you know where to find it and how to handle it. This comprehensive guide will walk you through the process step-by-step, ensuring your machine stays in top shape and your laundry comes out spotless.
Why Cleaning the Filter Matters
The drain pump filter in your Whirlpool top-loading washing machine serves as a gatekeeper, catching debris that could otherwise obstruct the drain hose or pump. Over time, lint, hair, small coins, or fabric fibers can accumulate, reducing water flow and causing drainage problems. You might notice symptoms like slow draining, standing water in the drum, or lint marks on freshly washed clothes—issues that frustrate users, especially in rental properties where maintenance history is unclear. Regular cleaning not only prevents these problems but also extends the lifespan of your machine, saving you from costly repairs or replacements. For top loaders, this task is particularly important because their design often traps more debris due to the agitator’s action.
Locating the Filter on a Whirlpool Top Loader
Finding the filter is the first hurdle, as its location varies depending on the model. For most modern Whirlpool top-loading washing machines, the drain pump filter is situated behind a small panel on the front of the machine, typically near the bottom right corner. This placement makes it accessible without needing to move the appliance—a relief for renters or those with limited space. Here’s how to pinpoint it:
1. Behind the Front Access Panel (Most Common)
- Location: Bottom front-right corner
- How to Access:
- Look for a small rectangular or circular panel.
- For rectangular panels, gently pry open with a flathead screwdriver.
- For circular panels, press the tab at the top to release.
2. Inside the Agitator (Older Models)
- Some older Whirlpool washers have a lint trap inside the center agitator.
- Remove the agitator cap or fabric softener dispenser to access it.
3. Behind the Back Panel (Rare, Older Models)
- If no front panel exists, the filter may be under the drum.
- Requires unplugging the washer, tilting it back, and removing the rear panel.
(Note: Newer high-efficiency (HE) models may not have a removable filter, relying instead on a self-cleaning pump.)
To confirm the exact location for your model, consult the owner’s manual. If you’ve lost it, Whirlpool’s website offers downloadable manuals by entering your model number (e.g., WTW4816FW2). For renters hesitant to move heavy appliances, the front panel location is the most likely and convenient spot.
Tools and Preparation
Before diving in, gather a few basic items to make the process smooth and mess-free:
- A shallow pan or bucket to catch water
- A towel for spills
- A flathead screwdriver (if needed to open the panel)
- An old toothbrush for scrubbing
- A cloth for wiping
Turn off the washing machine and unplug it from the power source to ensure safety. If possible, move the machine slightly forward to access the front panel more comfortably, though this isn’t always necessary.
Step-by-Step Guide to Cleaning the Filter
Once you’ve located the filter, cleaning it is a simple process. Follow these steps to remove, clean, and reinstall it properly:
Step 1: Prepare the Washer
- Unplug the machine for safety.
- Place a shallow pan or towel beneath the filter to catch residual water.
Step 2: Remove the Filter
- For front-panel filters:
- Twist the filter counterclockwise and pull it out.
- Water may drain out—let it empty completely.
- For agitator filters:
- Lift the agitator cap and remove the lint screen.
Step 3: Clean the Filter
- Remove large debris by hand.
- Soak the filter in warm, soapy water for 10 minutes.
- Scrub gently with a soft brush to remove buildup.
- Rinse thoroughly.
Step 4: Check the Filter Housing
- Wipe the inside of the filter compartment with a damp cloth.
- Remove any hidden debris (coins, hair, paper).
Step 5: Reinstall the Filter
- Insert the filter and twist clockwise to lock.
- Ensure it’s securely in place to prevent leaks.
Step 6: Run a Cleaning Cycle
- Pour 1 cup of white vinegar or a washing machine cleaner into the drum.
- Run a hot water cycle to flush out remaining residue.
Troubleshooting Common Issues
If cleaning the filter doesn’t resolve your problem, other culprits might be at play. Here’s how to address them:
- Lint on Clothes: For top loaders like the WTW4816FW2, Whirlpool often omits a traditional lint trap inside the drum. If lint persists post-filter cleaning, run a cycle with a washer cleaner like Glisten Washer Magic (available online). This product dissolves buildup within the tub and pump without disassembly.
- Drainage Problems: If water still won’t drain (e.g., F9 E1 error code), inspect the drain hose for blockages. Remove it, rinse it thoroughly, and reattach it securely.
- Odors: A smelly machine suggests mold or mildew. After cleaning the filter, leave the lid open between uses and run a hot cycle with vinegar or a washer cleaner monthly.
Cleaning the Supply Line Filters
Sometimes, water flow issues stem from the supply lines rather than the drain pump filter. These lines—hot and cold water hoses connecting the machine to your plumbing—have small filters that can clog with sediment. Here’s how to clean them:
- Turn Off Water: Close the supply valves by twisting them clockwise until tight. Unplug the machine for safety.
- Disconnect the Hoses: Use a wrench to loosen the nuts at both ends of each hose (machine and wall). Unscrew them by hand, catching any dripping water with a towel.
- Brush the Filters: Inside the valve stems (on the machine and wall ends), you’ll see small mesh screens. Gently brush them with a toothbrush to remove debris. Don’t use cleaners—just water and light scrubbing.
- Reattach: Screw the hoses back on by hand, then tighten with a wrench (1-2 extra turns). Open the valves counterclockwise and run a test cycle to check for leaks.
This step is especially relevant if you see error codes like Lf, LO FL, or F8 E1, indicating water intake issues.
Special Considerations for High-Efficiency Models
If your Whirlpool top loader is a high-efficiency model without a removable filter, maintenance shifts to the self-cleaning pump. To keep it clear:
- Run an empty self-cleaning cycle monthly (or a hot cycle with vinegar if no specific setting exists).
- Check the pump access hatch (usually front bottom) for blockages like socks or coins if drainage falters.
Maintenance Tips for Longevity
Regular care keeps your Whirlpool top loader humming along:
- Clean the Filter Quarterly: Every three months—or monthly for heavy use—prevents buildup.
- Wipe the Drum: After cleaning the filter, wipe the drum’s rim and agitator with a damp cloth to remove stray lint.
- Use HE Detergent: For HE models, stick to high-efficiency detergent to minimize residue.
- Inspect Hoses: Check supply and drain hoses yearly for wear or kinks.
When to Seek Help
If cleaning the filter and supply lines doesn’t fix drainage, lint, or odor issues, the pump itself might be faulty. Contact Whirlpool customer service or a local appliance repair expert. For renters, notify your landlord—moving or disassembling the machine might violate your lease.

FAQ: Whirlpool Washer Filter Cleaning
Does my Whirlpool washer have a lint trap?
Most top-load Whirlpool washers have a drain pump filter, not a traditional lint trap. High-efficiency (HE) models may rely on a self-cleaning system.
Why is my washer still not draining after cleaning the filter?
Check the drain hose for blockages.
Ensure the pump isn’t faulty (unusual noises may indicate a broken pump).
Can I use bleach to clean the filter?
No—bleach can damage rubber seals. Use mild detergent or vinegar instead.
