A top load washer is a common household appliance used to clean clothes and linens. Understanding how a top load washer works can help you use it more effectively and troubleshoot any issues. In this comprehensive guide, we’ll explore the inner workings of a top load washing machine and break down its key components and wash cycles.
How a Top Load Washer is Constructed
The main parts of a top load washer include:
Outer Tub
This is the main body of the washer. It is a large tub made of metal or plastic that holds the water and clothes. The outer tub does not fill with water directly. It encloses the inner wash basket and spin basket.
Inner Wash Basket
The inner basket is perforated and sits inside the outer tub. When the washer agitates, the inner basket rotates back and forth to move the clothes through the water and detergent solution for cleaning.
Spin Basket
The spin basket is perforated like the wash basket but sits lower in the tub. During the spin cycle, the wash basket lifts up while the spin basket spins rapidly to extract water from the clothes.
Agitator
In the center of the wash basket is a vertical column called the agitator. During the agitation cycle, the agitator twists and moves the clothes around for optimal cleaning. The agitation motion knocks dirt and debris loose from the fabric.
Motor
The motor powers the rotation of the agitator and spin basket. Top load washers usually have two motors – one for agitation and one for spinning. The motors connect to the baskets via a belt and pulley system.
Water Inlet Valve
The inlet valves control the hot and cold water supply into the washer tub. They open and close to allow the correct amount of water in during the fill cycles.
Drain Pump
The drain pump removes soapy water from the wash and rinse cycles. It pumps the used water out through the drain hose during certain stages of the cycle.
Lid Switch
A lid switch stops the washer from filling and running when the lid is open. This is a safety feature to prevent accidents.
Timer
The timer coordinates the progression of the washer through the wash cycle stages. It controls the motors, valves, and other components.
Water Level Switch
This determines the water level during the fill cycle to ensure the tub has the proper amount of water.
Temperature Switch
This monitors the interior tub temperature and adjusts the hot and cold water mixing appropriately.
How Top Load Wash Cycles Work
Now that we’ve looked at how a top load washer is built, let’s examine how the main wash cycles operate:
Fill
During the fill cycle, the washer tub fills with a mixture of hot and cold water to reach the optimal temperature. The water level switch shuts off the inlet valves when the proper fill level is reached.
Agitate
The agitation cycle consists of the agitator oscillating back and forth while the tub remains stationary. This motion rubs clothes against each other to scrub out dirt and move them around in the detergent solution. The duration of the agitation cycle varies by program.
Soak
Some wash cycles incorporate a soak period of 5-15 minutes where the tub is full of water and detergent solution. Soaking allows more time for stains to loosen before the agitation begins.
Drain
After agitating or soaking, the used water pumps out through the drain pump and hose. The timer activates the pump to empty the soiled water.
Rinse
Fresh water fills back up to rinse soap residue from the clothes. An agitation cycle also occurs to fully flush out detergent. The rinse water then drains. Most wash programs include multiple rinse cycles to fully remove soap.
Spin
The highest-speed spin cycle uses centrifugal force to extract water out of the clothes. The tub spins rapidly while the wash basket lifts up out of the way. The spin cycle prepares the laundry for the dryer or drying on the line.
Top Load Washer Cycle Options
While the basic wash steps stay the same, top load washers offer various cycle options to suit different fabric types and levels of soil. Here are some of the most common top load washer cycle programs:
Normal or Regular
As the name suggests, this is the standard cycle for average loads. It provides a balance of agitation time and number of rinses. The overall cycle lasts about 30-40 minutes on most models.
Heavy Duty or Super
This high-powered cycle is ideal for sturdy, heavily soiled items like jeans, workout wear, and dirty sports uniforms. It features longer agitation periods and extra rinse cycles.
Delicates or Handwash
For lightly soiled clothes and delicates prone to damage, this cycle has shorter agitation times and reduced spinning. The wash motion is slower and gentler.
Perm Press or Wrinkle Control
This cycle is designed to prevent wrinkling by limiting agitation time and having a cool down or spray rinse at the end. The shorter wash and spin help reduce creasing.
Sanitary or Sterilize
Extra hot temperatures and extended soak periods help kill germs and bacteria on laundry like sheets, towels, and baby clothes.
Quick or Speed Wash
As advertised, this cycle provides faster wash and rinse times for small, lightly soiled loads that need a refresh. The agitation motions are shorter but faster.
Rinse Only
Select this option if clothes just need an additional rinse cycle. It skips the wash portion and just adds rinse and spin steps.
Spin Only
Use this setting to manually select an extended high-speed spin if laundry is still too wet after a cycle finishes. It will rapidly spin out more water.
Top Load Washer Cycle Controls
Top load washers provide adjustable settings so you can customize the cycles for each load. Here are some of the ways to tailor the cleaning:
Wash Temperature
Set the desired water temperature for the wash and rinse cycles. Most models offer a range from cold to hot. Match the temp to the fabric care instructions.
Spin Speed
Faster spin speeds wring out more moisture, while slower speeds produce less wrinkling. Adjust accordingly for the fabric type.
Soil Level
Tell the washer if you have a light, normal, or heavy soil load so it can adapt the wash intensity.
Wash Time
Manually add wash time for extra cleaning of heavily soiled laundry in some models.
Rinse Options
Select between light, normal, or heavy rinse cycles depending on detergent residue concerns.
Cycle Signal
An audible chime can alert you when the wash cycle has finished. Turn this off for quieter operation.
Delay Start
Program a delayed start so the washer can run when convenient. Great for off-peak energy hours.
