Step By Step Guide To Deep Cleaning A Top Load Washing Machine Filter

Most homeowners overlook one of the most critical maintenance tasks for their laundry appliances: cleaning the washing machine filter. While top-loading washers don’t always have a visible filter like front-load models, many modern units include internal lint traps or drain pump filters that collect debris over time. When clogged, these components reduce efficiency, cause odors, and may even lead to mechanical failure. A deep clean every 3–6 months can prevent costly repairs and extend the life of your appliance. This comprehensive guide walks you through identifying, accessing, and thoroughly cleaning your top load washing machine’s filter system.

Why Cleaning Your Washing Machine Filter Matters

Even though top load washers are often considered lower maintenance than their front-loading counterparts, they still accumulate lint, hair, fabric fibers, and small foreign objects like coins or buttons. These materials get trapped in internal filtration systems before water is pumped out during the spin cycle. Over time, buildup restricts water flow, forces the pump to work harder, and creates a breeding ground for mold and mildew.

A poorly maintained filter leads to several issues:

• Longer drain cycles or incomplete draining
• Foul odors emanating from the drum
• Reduced wash performance due to poor water circulation
• Premature wear on the pump motor
• Increased risk of flooding if the drain becomes completely blocked

“Many service calls we receive for ‘broken’ washers turn out to be simple blockages in the filter or drain system. Regular cleaning prevents up to 40% of avoidable repairs.” — Carlos Mendez, Appliance Repair Technician with 15 years of experience

Locating the Filter in a Top Load Washer

Unlike front-load machines, which typically have an accessible filter behind a service panel at the bottom front, top loaders vary significantly by brand and model. Some older models do not have user-serviceable filters, relying instead on self-cleaning pumps. However, most newer high-efficiency (HE) top loaders—especially those with impeller-style agitators—include a filter or trap located near the pump assembly.

To determine if your machine has a cleanable filter:

1. Consult your owner’s manual under “Maintenance” or “Cleaning Instructions.” Look for terms like “pump filter,” “drain filter,” or “lint trap.”
2. If you no longer have the manual, search online using your model number (usually found inside the lid or on the back panel).
3. Look for a removable access panel on the exterior rear or base of the machine. Some brands place it behind a small kickplate at the bottom front.
4. Listen during the drain cycle. If you hear gurgling or notice slow drainage, it’s likely there’s a filter needing attention.

Tip: Not all top loaders have a traditional filter. Some use self-cleaning systems but still benefit from periodic inspection of the drain pump housing.

Tools and Supplies You’ll Need

Before beginning the cleaning process, gather the following items to ensure a smooth, mess-free experience:

Item	Purpose	Recommended Type
Towels or absorbent pads	To catch water spills during disassembly	Microfiber or old cotton towels
Bucket or shallow container	To collect residual water from the pump housing	5–10 liter capacity
Screwdriver (Phillips or flathead)	To remove access panels or screws	Size depends on your model
Gloves (rubber or nitrile)	To protect hands from sludge and bacteria	Disposable or reusable waterproof gloves
Soft brush or toothbrush	To scrub debris from filter and housing	Nylon-bristled, non-abrasive
Vinegar or washing machine cleaner	To sanitize and dissolve mineral deposits	White vinegar or manufacturer-approved cleaner
Flashlight	To inspect tight spaces and locate components	LED penlight or headlamp

Ensure the washer is unplugged and turned off before starting any work. Safety first—electrical components and water should never mix during maintenance.

Step-by-Step Guide to Deep Cleaning the Filter

Follow these steps carefully to safely access and clean your top load washer’s filter or drain pump housing.

1. Run a drain-only cycle. Start by selecting a short spin or drain cycle to remove as much standing water as possible. This minimizes spillage when opening the pump compartment.
2. Unplug the machine. Disconnect the power cord from the outlet. Never attempt internal cleaning while the unit is energized.
3. Move the washer forward (if necessary). For rear-mounted filters, gently pull the washer away from the wall to access the back. Turn off water supply valves and disconnect hoses only if obstructing access.
4. Locate and open the service panel. Depending on your model, the filter may be behind a plastic cover on the lower front, side, or back. Use a screwdriver to remove screws and carefully detach the panel.
5. Place towels and a bucket underneath. Position them beneath the pump housing to catch any remaining water. The amount varies—some units release only a cup, others up to a liter.
6. Open the pump filter cap. Most filters twist counterclockwise or have a latch mechanism. Turn slowly—pressure may cause water to seep out gradually. Remove the cap and set it aside.
7. Remove the filter or debris trap. Pull out the mesh screen, impeller guard, or internal basket. It will likely be coated in lint, hair, sand, or small particles. Rinse it under warm running water.
8. Clean the housing interior. Use a soft brush and vinegar solution to scrub the inside of the chamber. Pay attention to crevices where sludge accumulates. Flush with clean water afterward.
9. Inspect the impeller (if visible). In some models, you can see the pump impeller behind the filter. Spin it gently with your finger—it should rotate freely. If jammed, remove any string or fiber blocking movement.
10. Reassemble the unit. Reinsert the cleaned filter, tighten the cap securely (but don’t overtighten), and reattach the access panel. Replace any screws.
11. Restore power and test. Plug the washer back in, move it into position, reconnect hoses if detached, and run a rinse cycle without clothes to ensure proper drainage and detect leaks.

Tip: Perform this cleaning in the evening or when you can monitor the next few washes. Early detection of leaks prevents water damage.

Real Maintenance Scenario: Preventing Costly Repairs

Sarah, a homeowner in Portland, noticed her Samsung top load washer was taking nearly twice as long to drain. Clothes came out damp, and a musty smell lingered after every load. She tried running empty bleach cycles, but the issue persisted. After consulting an online forum, she discovered her model (WA50R7400AV) had a hidden pump filter accessible from the front lower panel.

Using a YouTube tutorial and her husband’s help, Sarah followed the steps above. Upon opening the housing, she pulled out a tangled mass of dog hair, sock fibers, and a lost hair tie—enough to fill half a coffee mug. After cleaning the filter and flushing the chamber with vinegar, she reassembled the unit. The next wash drained completely in under two minutes, and the odor disappeared. What could have led to a $250 service call cost her only 30 minutes and a few paper towels.

This example underscores how minor neglect can mimic major failures—and how proactive maintenance pays dividends.

Frequently Asked Questions

Does every top load washer have a filter?

No. Older or basic models may not have a user-accessible filter, relying on self-cleaning pumps. However, most HE top loaders manufactured after 2010 include a serviceable pump filter or lint trap. Consult your manual or manufacturer’s website to confirm.

Can I use bleach instead of vinegar to clean the filter?

Vinegar is preferred because it dissolves mineral buildup and kills mold without damaging rubber seals. Bleach is corrosive and may degrade plastic or elastomer parts over time. If you choose bleach, dilute it heavily (1:10 with water) and rinse thoroughly.

My washer still smells bad after cleaning the filter. What else can I do?

Odors often persist in the drum or hoses. Run a hot water cycle with 2 cups of white vinegar or a dedicated washing machine cleaner. Wipe the inner basin and rubber gasket (if present) with a vinegar-soaked cloth. Leave the lid open between uses to promote drying.
