Step By Step Guide To Cleaning A Top Loading Washer Filter Implied Smell Fixes

Top-loading washing machines are a staple in many households, prized for their ease of use and reliability. However, even the most dependable models can develop unpleasant odors over time—especially if maintenance is overlooked. A common culprit behind that musty, damp smell? The washer’s internal filter and drainage system, where lint, soap residue, and moisture accumulate. Left unchecked, this buildup not only causes foul smells but can also reduce cleaning efficiency and shorten the machine’s lifespan.

Cleaning your top loader’s filter isn’t as straightforward as with front-loaders, since many don’t have an easily accessible external filter. Instead, debris collects in hidden traps within the pump or drain lines. This guide walks you through identifying, accessing, and cleaning these components, along with proven odor-elimination strategies to keep your washer smelling fresh after every cycle.

Understanding Your Top Loader’s Filtration System

Unlike front-loading washers, which typically feature a visible filter at the bottom front, top-loading machines often rely on internal filtration mechanisms. These may include:

• Lint traps – Some models have small mesh screens near the agitator or along the water outlet hose.
• Pump filters – Located inside the drain pump assembly, these catch debris before water exits the machine.
• Drain hoses and sumps – Areas where water sits temporarily during cycles, prone to mold and mildew growth.

Because these parts aren’t always user-accessible without disassembly, many owners assume their machine doesn’t require filter maintenance. That misconception leads directly to odor development. According to appliance technician Mark Reynolds, “Over 70% of service calls for smelly washers stem from neglected internal debris traps—even in top loaders.”

“Even machines without removable filters need periodic deep cleaning. Residue builds up in crevices you can’t see, creating a breeding ground for bacteria.” — Mark Reynolds, Appliance Repair Technician with 18 years of experience

Step-by-Step Guide to Cleaning the Washer Filter and Internal Components

While your top loader may not have a labeled “filter,” key areas require manual cleaning. Follow this detailed process every 3–6 months to prevent odor recurrence.

1. Unplug the Machine
   For safety, disconnect the washer from power. Never work on electrical appliances while they’re plugged in.
2. Check the Owner’s Manual
   Locate model-specific guidance. Some brands (e.g., Whirlpool, GE, Samsung) place lint traps under the agitator or near the outer drum rim. Others integrate filters into the pump housing.
3. Remove Visible Lint Traps (If Applicable)
   If your model has a mesh screen near the center post or along the inner tub wall:
   • Use pliers or fingers to gently pull it out.
   • Rinse under warm water, scrubbing with an old toothbrush.
   • Inspect for tears; replace if damaged.
4. Access the Drain Pump Filter (Advanced Step)
   This requires partial disassembly:
   • Move the washer away from the wall.
   • Place towels underneath to catch water.
   • Remove the lower front panel using a screwdriver.
   • Locate the drain pump—a round plastic housing with a twist-off cap.
   • Slowly unscrew the cap. Water will spill out, so do this over a pan.
   • Remove accumulated hair, coins, buttons, and gunk.
   • Clean the chamber with a damp cloth and reinstall the cap securely.
5. Flush the Drain Hose
   Disconnect the hose from the back of the washer and inspect for clogs. Use a plumber’s snake or long bottle brush to clear buildup. Rinse thoroughly before reconnecting.
6. Reassemble and Test
   Replace all panels, plug in the machine, and run an empty hot water cycle to flush remaining debris.

Tip: Perform this cleaning at night or when you can monitor the area—some water leakage is normal during pump access.

Odor Elimination: Beyond the Filter

Cleaning physical debris helps, but lingering smells often persist due to microbial growth. Here’s how to neutralize odors at the source.

Vinegar and Baking Soda Deep Clean

These household staples break down organic residue and balance pH levels in the drum:

1. Add 2 cups of white vinegar directly into the drum.
2. Run a hot water cycle on the highest setting.
3. Pause the cycle after filling, then let it soak for 1 hour.
4. Resume and complete the wash.
5. Follow with a second cycle using ½ cup baking soda added to the detergent drawer.

Monthly Maintenance Routine

Prevent future odors with consistent care:

• Leave the lid open between uses to promote air circulation.
• Wipe down the rubber gasket (if present) and inner rim weekly.
• Use high-efficiency (HE) detergent to minimize suds residue.
• Avoid overloading, which traps moisture and reduces rinse effectiveness.

Enzyme-Based Cleaners

For stubborn biological odors (like mildew or sweat), enzyme cleaners target the root cause. Products like Affresh Washer Cleaner or OxiClean Washing Machine Cleaner dissolve organic matter more effectively than vinegar alone.

Method	Best For	Frequency	Notes
Vinegar Wash	General deodorizing, mineral buildup	Every 1–2 months	Do not mix with bleach
Baking Soda Cycle	Neutralizing acidic odors	Monthly	Use after vinegar for best results
Commercial Washer Cleaner	Heavy mold/mildew, long-term neglect	Every 3–6 months	Follow product instructions carefully
Manual Pump Cleaning	Visible debris, slow drainage	As needed (every 6–12 months)	Requires tools and caution

Real-World Example: Solving a Persistent Smell Issue

Sarah from Columbus, Ohio, noticed her clothes were coming out with a sour odor despite using quality detergent and running regular loads. She tried multiple vinegar rinses with no lasting improvement. After consulting a technician, she learned her 5-year-old Maytag top loader had a hidden pump filter clogged with pet hair and fabric softener residue—a common issue in homes with pets and heavy softener use.

Following the technician’s advice, Sarah removed the front panel and cleaned the pump chamber, extracting a dense clump of gunk. She then ran two consecutive cleaning cycles: one with vinegar, another with an enzyme-based cleaner. Within days, the smell vanished. “I had no idea my washer had a filter,” she said. “Now I clean it twice a year, and my towels finally smell clean again.”

Common Mistakes That Worsen the Problem

Even well-intentioned users can make errors that exacerbate odor issues. Avoid these pitfalls:

• Using too much detergent – Excess suds trap dirt and create sludge.
• Running cold-only cycles – Cold water doesn’t kill bacteria or dissolve grease effectively.
• Sealing the lid immediately after use – Trapped moisture breeds mold.
• Ignoring the detergent drawer – Pull it out monthly and rinse under water to remove buildup.
• Mixing bleach and vinegar – Creates toxic chlorine gas. Never combine them in the same cycle.

Tip: Run a hot water \"clean drum\" cycle once a month, even if you don’t notice smells. Prevention is easier than remediation.

FAQ: Your Top Loading Washer Filter Questions Answered

Does my top load washer have a filter?

Most do—not always visible. Check under the agitator, around the wash plate, or inside the drain pump. Consult your manual for exact location. If none exists, focus on cleaning the drain system and running regular maintenance cycles.

Why does my washer smell like rotten eggs?

This sulfur-like odor usually indicates bacterial growth in stagnant water mixed with organic matter (lint, sweat, etc.). It’s common in machines used infrequently or left closed. Flush the system with hot water and vinegar, clean the pump if possible, and leave the lid open between uses.

Can I damage my washer by cleaning the filter myself?

Only if proper precautions aren’t taken. Always unplug the unit, turn off water supply, and handle plastic components gently. Reconnect hoses securely to avoid leaks. If unsure, consult a professional—especially for complex disassembly.

Essential Maintenance Checklist

Stay ahead of odors and performance decline with this actionable checklist:

• ☐ Unplug the washer before any internal cleaning
• ☐ Locate and remove lint trap (if present)
• ☐ Access and clean the drain pump filter every 6 months
• ☐ Inspect and flush the drain hose annually
• ☐ Run a hot water cleaning cycle with vinegar monthly
• ☐ Use an enzyme-based cleaner every 3–6 months
• ☐ Leave the lid open after each use
• ☐ Wipe down the tub rim and detergent dispenser weekly
• ☐ Replace worn hoses every 5 years
• ☐ Keep the area around the washer dry and ventilated

Conclusion: Take Control of Your Washer’s Freshness
