Whirlpool Washing Machine Cleaner Tablets: The Complete Guide

Whirlpool is one of the two largest-selling washer brands in the US, accounting for a significant share of top load units sold nationwide. The brand's machines range from entry-level top loaders with traditional agitators to high-efficiency front loaders with the FreshFlow Vent System. Each type has its own maintenance profile.

Despite design differences, all Whirlpool washers face the same core maintenance challenge: detergent residue, mineral scale, and trapped odor-causing buildup can collect inside components that regular wash cycles do not fully clean. The drum gets rinsed with every load, but the internal hoses, valve housing, pump, and agitator shaft do not.

A cleaner tablet used monthly helps address this buildup systematically. The guide below explains the Whirlpool-specific details   which cycle to use, where the tablet goes, how agitator and impeller machines differ, and what to do when basic cleaning does not resolve a persistent smell.

Why Whirlpool Washers Need Monthly Cleaning Tablets

Every wash cycle leaves behind a small amount of residue. Detergent that does not fully dissolve can settle on internal surfaces. Fabric softener can coat the dispensing system and drum rim, while hard water leaves mineral scale inside the pump and valve housing over time. These materials do not fully flush out during normal laundry cycles because they build up on surfaces the wash water does not regularly reach at cleaning temperatures.

Whirlpool's own documentation identifies four leading causes of washer smells: using too much detergent, using non-HE detergent in an HE machine, leaving the lid or door closed between uses, and not running a cleaning cycle regularly. Cleaning tablets help address the accumulated effect of all four by reaching internal areas during a dedicated hot cleaning cycle.

Top load Whirlpool washers with agitators carry an additional maintenance concern. The agitator shaft, the fabric softener dispenser cup, and the crevices under the agitator cap can collect residue that the drum cleaning cycle water does not fully reach. Appliance technicians often find the area under the agitator cap to be one of the most common locations for heavy buildup in older Whirlpool top loaders.

What Accumulates Inside a Whirlpool Washer Over Time

Whirlpool Washer Cycle Types and How Cleaner Tablets Work With Each

Whirlpool uses different names for the dedicated washer cleaning function across its model range. The table below shows the correct cycle for each type. If your model name does not appear, check the control panel for any cycle labeled Clean, Clean Washer, or Self Clean. If your washer does not have one of these options, a Normal cycle on the hottest water setting is the best alternative.

Finding the Clean Washer Cycle on Newer Whirlpool Models

On Whirlpool touchscreen front loaders (such as the WFW9620HW and similar models), the Clean Washer cycle may not always appear on the main cycle selection screen. Depending on the model, there are three common ways to access it:

• Cycle selector knob: Turn the knob to the Clean Washer position, then press Start/Pause.

• Touchscreen home screen: Tap the home screen, select Clean Washer, then choose How to Wash and confirm.

• Tools menu: Tap the Tools icon on the display. The Clean Washer  . may appear as a utility cycle alongside Drain and Spin.

If none of these options apply to your model, check pages 13 to 15 of your use and care manual. Whirlpool usually includes the Clean Washer instructions in that section for most current models. 

Step-by-Step: How to Use Cleaner Tablets in Your Whirlpool Washer

The core process is the same across all Whirlpool models. The differences lie in which cycle to select and whether any additional steps apply to your washer type.

Whirlpool Top Load Washer With Agitator

Agitator models benefit the most from monthly tablet cleaning because the agitator assembly can collect buildup in areas the cleaning cycle water reaches last. Follow these steps:

1. Remove all laundry from the drum and make sure the basket is completely empty.

2. If your agitator has a removable cap, remove it and wipe the inside of the agitator with a damp cloth before running the cleaning cycle. Replace the cap afterward.

3. Drop one True Fresh Washing Machine Cleaning Tablet directly into the drum at the base of the agitator. Do not place it in the detergent drawer, fabric softener cup, or bleach compartment.

4. Select the Clean Washer. If your washer does not have this option, choose the Normal cycle with the hottest water setting and use Deep Fill if available.

5. Press Start. Do not add laundry, detergent, or any other cleaner during the cycle.

6. After the cycle is complete, run an optional Rinse and Spin cycle if you notice any foam or leftover residue in the tub.

7. Leave the lid open for at least 30 minutes after the cycle finishes. This helps the drum air dry and reduces moisture buildup.

Whirlpool Top Load Washer With Impeller (No Agitator)

Impeller models usually collect less visible residue in the drum because the low-profile impeller plate has fewer crevices than a traditional agitator. However, internal components still need monthly cleaning. The process is simpler:

1. Empty the drum completely.

2. Drop one tablet directly into the center of the drum, over the impeller plate.

3. Select the Clean Washer cycle or the hottest available wash cycle.

4. Press Start and allow the cycle to complete without interruption.

5. After the cycle finishes, leave the lid open so the washer can dry properly.

Whirlpool Front Load Washer

Front load washers require a little more maintenance beyond the regular drum cleaning cycle. The rubber door gasket folds can trap moisture, lint, and residue after every wash, so the gasket should be cleaned manually after the cleaning cycle finishes.

1. Remove all laundry and make sure the drum is completely empty.

2. Drop one tablet directly into the bottom of the drum. Do not place it in the detergent drawer.

3. Select Clean Washer, Clean Washer, or Self Clean. These cycles run at a higher temperature for better cleaning.

4. Press Start and allow the cycle to finish without opening the door mid-cycle.

5. After the cycle is complete, gently pull back the rubber door gasket folds and wipe them dry with a clean cloth. Remove any trapped lint, debris, or moisture.

6. Wipe the drum interior and the door glass with a dry cloth.

7. Leave the door slightly open for at least 30 minutes so the washer can air dry properly. On Whirlpool models with FanFresh or Dry Drum Cycle, using that feature after cleaning helps dry the gasket and drum more thoroughly.

Cleaning the Whirlpool Agitator: The Step Most People Miss

The monthly cleaning cycle with a tablet helps clean the drum, pump, hoses, and valve areas. The agitator itself   especially the removable cap and the inside of the agitator post   also needs manual attention every 30 to 60 washes because the cleaning cycle water may not fully reach these surfaces.

Whirlpool offers several models with a 2-in-1 Removable Agitator, which makes this step much easier. Whether your agitator is removable or fixed, the cleaning process for the accessible surfaces remains the same.

 How to Clean the Whirlpool Agitator

1. Check your user manual before attempting to remove the agitator cap. Not all agitator caps are designed to be removed, and forcing a fixed cap can damage the agitator assembly.

2. If the cap is removable, gently twist or pull it upward to remove it. In most models, the cap either lifts straight off or requires a simple quarter-turn.

3. Wipe the inside of the agitator post with a damp cloth or a narrow bottle brush. This is one of the most common areas where dark residue and buildup can collect over time.

4. Clean the agitator fins and the base area where the agitator meets the drum using a soft cloth dampened with warm water.

5. Remove the fabric softener dispenser cup from the agitator (if your model has one) and rinse it under warm running water. For heavier buildup, let it soak in warm water for about 5 minutes before rinsing.

6. Replace the cap and dispenser cup. Run the monthly cleaning cycle with one tablet immediately after to help flush away any loosened residue.

Whirlpool’s 2-in-1 Removable Agitator models allow the full agitator post to be removed for easier cleaning. On these machines, doing a deeper agitator clean every 3 to 4 months helps prevent heavy buildup that can develop over time.

 Why Your Whirlpool Washer Smells: The Root Causes

The most common Whirlpool washer smell questions searched online include “why does my Whirlpool washer smell musty,” “Whirlpool washer smells bad,” and “Whirlpool top loader smell near agitator.” These issues usually trace back to the same root causes, which regular monthly cleaning with a washer cleaning tablet helps prevent.

Scrud: The Agitator Problem Unique to Older Whirlpool Top Loaders

“Scrud” is a common term used for the brown or gray sludge that can build up inside the outer tub of top load washers over time. It usually forms from a mix of undissolved detergent, fabric softener, lint, and hard water minerals. In Whirlpool agitator models especially those used mostly with cold water and liquid detergent this buildup can form a thick layer along the outer tub wall.

As the washer runs, small pieces of this buildup can break loose and stick to clothing. Many users notice gray or brown flakes appearing on dark laundry after washing. Regular monthly cleaning with a washer cleaning tablet helps prevent this buildup from reaching that stage.

If scrud has already formed, running two back-to-back cleaning cycles with tablets, followed by wiping the drum interior and agitator base, helps loosen and remove the existing buildup before returning to normal monthly maintenance.

Whirlpool Washer Model Guide: Cleaning Cycle and Tablet Placement

Whirlpool offers several washer series with different control layouts and cleaning cycle names. The table below shows the correct cleaning cycle and tablet placement for the most common Whirlpool washer models sold in the US.

Whirlpool Washing Machine Cleaner Tablet FAQ

Where does the cleaning tablet go in a Whirlpool washer?

Always place the tablet directly in the drum or basket — never in the detergent drawer, fabric softener cup, or bleach compartment. Place it at the bottom of the empty drum. On agitator models, place it at the base of the agitator. On impeller models, place it over the impeller plate. On front load washers, place it on the drum floor. This allows the tablet to dissolve properly throughout the full cleaning cycle and helps reach internal areas where residue can collect.

How often should I run the Clean Washer cycle on my Whirlpool washer?

Whirlpool recommends cleaning every 30 wash cycles or about once per month. For households doing laundry daily or almost daily, 30 cycles may happen within 3 to 4 weeks, making monthly cleaning a practical routine. Homes with hard water, frequent heavy loads, or pet laundry may benefit from cleaning every 3 weeks.

Can I use a cleaning tablet and bleach at the same time?

No. Whirlpool recommends not combining multiple cleaning products in the same cycle. If your washer manual allows bleach for a specific deep-cleaning situation, use it separately through the detergent compartment, complete that cycle, and then run a Rinse + Spin cycle before using any other cleaner. Do not place bleach directly into the drum. Mixing bleach with tablets or other cleaners is not recommended.

Why does my Whirlpool washer still smell after I run the Clean Washer cycle?

Three common reasons cause persistent smells after running the Clean Washer cycle without a tablet. First, the cycle uses heat and movement, but without a cleaner tablet, it may not fully address internal residue buildup. Second, the pump filter may be clogged with lint, hair, or debris, which can hold stagnant water and create smells. Third, on front load washers, the rubber door gasket folds can trap moisture, lint, and dark residue that require manual wiping after every wash.

Does using a cleaning tablet void my Whirlpool warranty?

No. Whirlpool’s warranty covers manufacturing defects, and using a compatible washing machine cleaner tablet for regular maintenance does not void the warranty. Whirlpool also notes that other cleaner products may be used depending on the washer model, so checking your specific manual is always recommended.

How do I clean a Whirlpool washer with a removable agitator?

Remove the agitator cap if your model allows it, then wipe the inside of the agitator post, the fins, and the base area with a damp cloth. Clean the fabric softener dispenser cup under warm running water. Replace the parts and run the Clean Washer cycle with one tablet in the drum. A deeper agitator clean every 3 to 4 months works well alongside monthly tablet cleaning.

Is a washing machine cleaner tablet safe for Whirlpool HE washers?

Yes, as long as the tablet is labeled HE-compatible. True Fresh tablets are designed for HE washers and work with low-sudsing formulas suitable for high-efficiency machines. Regular laundry detergent can create too many suds in HE washers, but dedicated cleaner tablets are made for safe monthly maintenance.

Can I use vinegar to clean my Whirlpool washer?

Whirlpool does not recommend using vinegar as a regular washing machine cleaner. Their support pages note that repeated vinegar use may affect internal machine components over time. Vinegar may help with temporary surface smells, but it does not remove detergent residue, mineral scale, or hidden buildup that causes long-term washer smells. For monthly maintenance, a dedicated cleaner tablet is the better option.

What is “scrud” and how do I get rid of it in my Whirlpool washer?

Scrud is a mix of detergent residue, fabric softener, lint, and mineral buildup that forms as brown or gray sludge inside top load washers, especially around the outer tub wall and under the agitator. It is more common in washers used mostly with cold water and liquid detergent. To remove existing scrud, run two back-to-back Clean Washer cycles with one tablet each, then wipe the drum interior and agitator base with a damp cloth. After that, return to monthly cleaning to prevent buildup from coming back.

How long does the Whirlpool Clean Washer cycle take?

On most Whirlpool top load washers, the Clean Washer cycle takes about 60 minutes. On front load models, it usually runs between 60 and 90 minutes depending on the series. Smart Whirlpool washers may also display the estimated cycle time on the app or control panel before starting.

Does a cleaning tablet work with Whirlpool smart washers?

Yes. Whirlpool smart washers use the same drum, pump, and heating system as standard models. Simply place the tablet in the empty drum and select the Clean Washer cycle using the control panel or connected app. Many Whirlpool smart models also allow you to set cleaning reminders every 30 cycles, which matches the recommended monthly maintenance schedule.

Tablets vs. Other Methods: Side-by-Side for Whirlpool Washers

Whirlpool owners often compare cleaning tablets with bleach, vinegar, and baking soda before choosing a washer cleaning routine. The table below shows Whirlpool’s general guidance along with the practical differences between each cleaning method.

Summary: Whirlpool Washer Cleaning Tablet Routine

Monthly tablet cleaning, paired with the Clean Washer cycle, helps remove what regular wash cycles often miss: internal residue, mineral scale, and odor-causing buildup inside the washer. The setup takes only a few minutes, and the cleaning cycle runs on its own.
