How Does a Front Load Washer Work?

Overview of Front Load Washers

Front-loading washers are known for their efficient cleaning capabilities. Unlike top-load washers, these machines have a horizontal drum that rotates to agitate and clean clothes. This design offers numerous benefits, such as better water usage and gentler handling of fabrics.

The main components of a front load washer include:

• Wash tub: The large, horizontal plastic tub suspended in the washer cabinet by springs and shocks.
• Spin basket: Stainless steel cylinder inside the wash tub that holds the clothes.
• Drive motor: Connect to the spin basket directly or with a drive belt, this motor rotates the spin basket to tumble and spin out the clothes during the wash cycle.
• Fill valve assembly: Electrically operated water valves that fill the washer with water during the wash cycle.
• Dispenser drawer: Holds detergent, bleach and fabric softener. Dispenses the additives into the wash tub at the right time during the wash cycle.
• Drain pump: Drains water from the washer during the cycle.
• Control panel: Allows you to start and stop the wash cycle and select cycle settings.

The washing process in a front load washer relies heavily on drum rotation and water flow. The drum tumbles the clothes, lifting and dropping them repeatedly to ensure thorough cleaning. This tumbling motion, combined with efficient water usage, helps detergent penetrate every fiber of the fabric, resulting in cleaner clothes with less wear and tear.

Front load washers use less water than top load washers thanks to their unique design. The spin basket uses strategically placed baffles (or paddles) to tumble and immerse the clothes in a small amount of water at the bottom of the wash tub during the wash cycle. This not only conserves water but also enhances cleaning performance.

Fill Cycle

The fill cycle in a front load washer is crucial for preparing the machine for the washing process. Water enters the washer through an inlet valve at the back of the machine. When the fill cycle is selected, the valve opens to allow water into the drum. The amount of water varies based on load size and selected water level options. A sensing system determines the size of load and fills the tub with the right amount of water.

Front load washers offer different water temperature settings to accommodate various fabrics and load sizes. You can choose hot, warm, or cold water options. Temperature sensors detect fill water temperature and control the hot and cold water fill valves to fill the wash tub with water at the selected temperature.

Dispenser Drawer

The dispenser drawer is a vital component of a front load washer, allowing you to add detergent, fabric softener, and bleach to tub at the right time during laundry cycles. Understanding how a washing machine works, including how to use the different compartments in the dispenser drawer, is essential for achieving clean and fresh-smelling clothes.

Dispenser Drawer Components

The dispenser drawer typically includes three compartments:

• Detergent compartment: This compartment holds laundry detergent – powder or liquid.
• Fabric softener compartment: Used for adding fabric softener or other laundry additives.
• Bleach compartment: This compartment is for adding bleach and is labeled accordingly.

A control system on the dispenser drawer housing routes water through the compartments at the right time during the cycle to dispense the detergent and additives.

How to Use the Dispenser

To use the dispenser drawer correctly, follow these steps:

1. Refer to the washer's user manual to identify the specific compartments and how to use them. You’ll often need to remove an insert from the detergent compartment when using powdered detergent.
2. Pour the recommended amount of detergent into the detergent compartment, avoiding overfilling. Because a front load washer uses less water, you’ll typically only need about a tablespoon of HE detergent for most laundry loads.
3. Add fabric softener to the fabric softener compartment, following the product label instructions. Some front load washers recommend diluting fabric softener with water so it flows into the tub freely during the cycle.
4. If using bleach, pour the appropriate amount into the bleach compartment. On many front load washers, not all cycles dispense bleach. Check your owner’s manuals for details about which cycles dispense bleach in your model.
5. Close the dispenser drawer and start the desired laundry cycle.

Cleaning and Maintaining the Dispenser Drawer

Regular cleaning and maintenance of the dispenser drawer are important to prevent the buildup of detergent or fabric softener residue. Here are some tips to keep it in optimal condition:

1. Remove the dispenser drawer and rinse it with warm water to remove any residue.
2. Use a mild detergent and a soft brush to clean the compartments thoroughly.
3. Allow the dispenser drawer to dry completely before reinserting it into the washer.
4. Inspect the dispenser drawer regularly for signs of damage or blockage and replace if necessary.

Wash Cycle

After filling, the drive system kicks in and tumbles the clothes. The electronic control board in the washer determines the speed and direction of tumbling action to clean the clothes effectively based on load size and cycle selection.

After tumbling to clean the clothes, the dirty water is drained from the tub by the drain pump.

The fill valves refill the tub for the rinse cycle and fabric softener is dispensed in the rinse water. The drive system again kicks in and tumbles the load to rinse detergent from the clothes.

After rinsing, the drain pump empties the wash tub and the drive system spins the basket at high speeds to sling water out of the clothes. After spinning, the cycle ends.

Front Load Washer Maintenance

Regular cleaning will help keep your front load washing machine smelling fresh and working properly. Follow the expert tips shown in this video to keep your front load washer clean and working properly.

Use a washing machine cleaner such as Affresh to clean the washer tub monthly. You may need to clean the washer more often if smells develop.

Wiping down the rubber door boot with a bleach and water solution every month is essential to preventing odors. Mold and mildew can develop quickly in the folds of the door boot. Bleach will kill mold and mildew and help prevent new growth between cleanings.

If your washer has a drain pump filter access door on the bottom left side of its front panel, clean the drain pump filter at least every 6 months. The diagram below shows how to clean the drain pump filter in many front load washers.

Items such as coins and paper clips can wind up in the drain pump filter. You may also find hair and lint in the filter. If you smell an awful odor when you pull out the drain pump large item filter, follow these steps to get rid of the smell:

1. Clean the filter and its housing with a bleach and water solution.
2. Run an empty Bulky wash cycle using hot water with a cup of chlorine bleach added.
3. Run an empty cycle with no detergent or additives to rinse all bleach out of the washer.
4. Cut back on the amount of detergent and additives that you’re using to prevent the awful smell from returning.
5. Clean the drain pump large item filter more often and check for continued odor problems.

If you see damage to the drain pump when cleaning the filter and housing, schedule washer repair service and we’ll send a technician to your home to fix the problem.

Schedule Annual Maintenance by a Service Technician

Have a service professional clean and maintain your front load washer yearly to help prevent odors and breakdowns. The technician will examine and adjust all parts of the washer to help keep it in top condition and minimize wear. The tech will also replace any worn components before they break completely so you won’t be stuck without a washer and waiting for washer repair due to an unexpected part failure. Schedule annual washer maintenance and cleaning through Sears Home Services to help keep your washing machine in top shape and lasting longer.

By understanding how a front load washer works and how to maintain it, you can ensure that your machine operates efficiently and delivers clean, fresh laundry every time.
