How a top-loading washing machine works?

Many homes have top-loading washing machines because of their simple design and ease of use. For those who would rather not bend over, these washers are convenient because they accept clothes added from the top, unlike front-loading models. But how precisely do they function?

The agitator, also known as the impeller, powers a top-loading washing machine by swirling the clothes around in the water. After the machine is filled with water, the impeller or agitator rotates to produce a cleaning motion. By doing this, you can help your clothes become clean by removing stains and dirt from the fabric.

The machine goes through several stages, including washing, rinsing, and spinning, during the washing cycle. The machine’s system controls every step automatically, so all you have to do is program the cycle and let the washer take care of the rest. The machine spins the clothes to remove extra moisture after washing, draining the water and preparing them for drying.

Step	Description
Filling	Water fills the drum through the inlet valve.
Agitation	The agitator in the middle moves clothes and water around.
Washing	The machine mixes detergent with water to clean clothes.
Rinsing	Clean water is used to rinse out soap from the clothes.
Spinning	The drum spins to remove excess water from the clothes.
Draining	Water is pumped out through the drain hose.
Completion	Clothes are ready to be removed and dried.

Components of a top-loading washing machine

Knowing every part of a washing machine is essential to becoming familiar with it. You can only understand the relationship between the design elements and their location by carefully studying the names and purposes of the main units. As a result, the following components are required for every top-loading washing machine:

• electric motor;
• washing tank;
• metal drum with doors-flaps;
• drain pump;
• rubber pipes and hoses;
• drum pulley;
• drive belt (if the washing machine does not have a direct drive);
• powder and gel tray (also called a powder receptacle and dispenser);
• shock absorption system (springs, vibration dampers);

Things are loaded through the top cover of washing machines with top loading capabilities!

• tubular electric heater (TEN);
• drain filter;
• control board (control module);
• dashboard;
• snail;
• thermistor;
• counterweights;
• electronic lock (UBL);
• inlet valve;
• cuff;
• pressure switch (water level sensor).

The washing machine’s parts are all "hidden" inside a metal casing. Blind panels are located on the sides, and there is a hatch cover and "dashboard" at the top. Frequently, a tray is fastened to the machine’s underside.

The names by themselves are insufficient to inspect the machine and diagnose the issue; you also need to be aware of its components’ locations, functions, and structure. Let’s examine each component in more detail.

The “center” of the machine control

The majority of washing machines in use today are electronic. In contrast to the "old" mechanics, a module—a connecting unit made up of sensors, conductors, tracks, and microcircuits—performs and regulates everything in this system. The following is how the system operates:

• the user sets the cycle settings by pressing buttons or turning the programmer on the dashboard;
• control board records the selected parameters and gives a command to execute the program;
• the necessary system units are turned on;
• the washing starts.

The washing machine is started by the control module, which interprets data from the dashboard and sends commands "along the chain" to the appropriate location. All operations, including turning on the apparatus, adding water, speeding up the engine, and emptying the tank, require "permission" from the electronic unit, which is made up of numerous triacs, sensors, and contacts. Following that, the board tracks the signals and data coming from the units to keep an eye on the status of the work. If there’s a malfunction or deviation, the device logs it and quickly stops the cycle.

Testing and soldering the board at home is not advised; instead, professionals should handle the firmware and testing!

When an electronic component malfunctions, the machine either "freezes" or cannot be turned on or respond to commands from the user. It is challenging to identify the issue because it could be with a single track or the control unit as a whole. In any event, the board is no longer able to operate the washing machine and stops letting it run for security.

The electronic module is a very intricate component. Finding out how it is set up and operates on your own can be challenging, particularly for those without any background in electrical engineering. It is best to avoid taking chances and to get in touch with the service center right away if you think there may be a board malfunction.

Parts responsible for clean water

A vertical washing machine’s filling system is represented by an inlet valve, hoses, and a pressure switch. As soon as the user presses the "Start" button on the dashboard to launch the program, water intake starts. The following plan is followed when filling the drum:

• the board receives a signal about the need to fill;
• pressure switch – a water level sensor, measures the pressure in the tank and signals the degree of filling;
• the module makes sure that there is no water in the tank and sends a command to the valve to fill;
• The voltage is supplied to the inlet valve, its membrane works, the damper rises;
• water from the water pipe flows into the machine through the inlet hose;

A lengthy tube on the pressure switch measures the pressure inside the tank by descending into it.

• The pressure switch controls the volume of water;
• When the required volume is reached, the pressure switch signals the unit;
• The module shuts off the current supply;
• The valve membrane closes;
• The set stops.

The water level sensor is the primary "controller" of the filling system, with all its components interacting continuously. It keeps the tank filled to a specific level and guards against overfilling or underfilling.

The "heart" of the machine

The washing machine’s engine is its "heart." The cylinder rotates at the intended speed because the electric motor accelerates the drum shaft. The tachogenerator, an engine-mounted device that continuously measures speed to prevent erratic rotation and sudden direction changes, regulates the number of revolutions.

The electric motor is the power source. Inverter motors on contemporary vertical machines are directly mounted to the drum shaft, negating the need for a drive belt. Because there are no "intermediaries" in this system, the cylinder spinning is safer, more dependable, and more efficient.

A few washing machines with vertical loading also have collector motors. Here, a drive belt that is thrown over the pulleys transmits the motor’s impulse to the drum. While less expensive, this option is less dependable because the rubber frequently flies off and breaks or stretches. The second drawback is the electric brushes, which eventually need to be replaced because they wear out on the engine body during machine operation.

The way a top-loading washing machine operates is by adding water to the drum, submerging the clothes, and then agitating them with an impeller or agitator. This motion aids in removing and loosening dirt. Before the cycle concludes, the machine drains the used water, fills it up again with fresh water to rinse the clothes, and then spins them to get rid of any leftover water. Many homes choose it because of its vertical design, which makes loading and unloading from the top simple.

Where does the hot water come from?

Similar to front-loading machines, vertical machines are heated by a tubular electric heater, or TEN. The electronic board accepts the parameters and turns on the heater as the user chooses the mode and modifies the temperature. After receiving a signal, the part starts to heat up as its "spiral" is brought to the tank and poured out.

Don’t run three high-temperature cycles in a row to prevent the heating element from overheating!

A temperature sensor called a thermistor keeps track of the amount of heating. It is housed inside the heating element itself and resembles a metal tube. The gadget alerts the module, which causes the heater to "reset," when the predetermined degrees are reached.

Weights and shock-absorbing system

Shock absorbers mitigate the centrifugal force that arises when the drum spins. They prevent the equipment from "jumping" around the room and hitting the wall by compensating for the outgoing vibration. The following components make up the washing machine’s stability:

• dampers – vibration dampers-racks with a built-in spring, connecting the washing tank to the machine body;
• springs – the tank is suspended on them from above and from the sides;
• counterweights – concrete blocks that are attached to the bottom or sides of the vertical, weighing down the entire structure.

The entire "blow" is absorbed by the depreciation system. The counterweights loosen, the springs stretch, and the dampers deteriorate as a result of continuous vibration. particularly if the washing machine is misused or improperly installed. In this instance, replacing the worn-out parts and tightening the fixing bolts are required.

Lock and seal

Every vertical has an electronic and a mechanical component. When the door is closed normally and the locking "tongue" slides into the appropriate groove, the mechanisms are activated. Because the UBL is a locking device, electronics turn on automatically when the washing program begins. The user won’t be able to open the drum once the cycle has begun because of the latter.

The hatch cuff, a rubber seal that is stretched over the cylinder’s edges, is also to blame for the drum’s tightness. It seals the space between the body and the tank to stop leaks and blockages in the system. You cannot begin washing if the elastic band is damaged because the water will start to leak.

Electric pump

Drain is a necessary stage in any program. There are hoses, pumps, drainage filters, and nozzles to completely destroy the car’s tank. The pump that transfers the spent liquid from the drum to the sewer is the main component of the drainage system.

Two different kinds of pumps are fitted to the verticals:

• synchronous;
• asynchronous.

Every pump has the same configuration. A motor propels and accelerates the impeller, a screw that gives water the correct trajectory, in order to launch the device. A drainage hose and nozzles are attached to the snail’s fixed pump, which is connected to the fluid outflow.

The majority of the dirt and debris deposited on the washer’s spirals is prevented from clogging it by the garbage filter!

Rarely do issues arise when pumping water, and they are not related to pump malfunctions. The obstruction of hoses that entered the garbage washer is the primary cause of the draining issue. The drainage filter, where outsiders become stuck and mud settles, is most affected. You must routinely clean the nozzle, the drainage system’s components, and the pockets in order to prevent this from happening.

Main tanks

The washing machine’s sealed plastic tank is its main component. The powder is combined with the tap water. The tank is situated with the opening facing upwards on vertical machines and forwards on front machines.

The material of the drum is stainless steel. After stuffing clothing into the cylinder, the engine spins it at a predetermined speed. It’s smaller, with walls punctured, and rib punches, which are plastic blades that "mix" materials and cause the powder to foam.

The drum volume varies based on the machine’s capacity, ranging from 3.5 to 15 kg.

The vertical drum of a top-loading washing machine makes it simple to load and unload clothes from the top. For those who would rather not bend over in order to access the machine, this design is convenient.

To guarantee that the detergent reaches every fiber, water is poured into the drum from the bottom and the clothes are moved around by the central agitator or impeller. During the wash and rinse cycles, the spinning motion aids in the soap and dirt removal process.

Prior to the drying process starting, the machine also spins the clothes to remove extra water. Laundry becomes more efficient as a result of the decreased time and energy required to dry them.

Top-loading laundry machines are renowned for their dependability and ease of use. They are a well-liked option for homes searching for a simple and efficient laundry solution.
