Monitoring the process of cleaning dishes in real time is not an easy task, because most modern models PMM have a completely closed body. However, thanks to technical experiments by enthusiasts and transparent prototypes, we have a unique opportunity to look “under the hood” of this complex unit. Videos taken with cameras installed inside show that behind the quiet hum lies a turbulent whirlpool of high temperature and pressure.
A real engineering drama unfolds inside the camera, where every second of the cycle is strictly regulated by electronics. High pressure water streams attack contaminants from all sides while chemical reactions detergent break down fat. Understanding these processes helps not only to satisfy curiosity, but also to correctly diagnose malfunctions, which are often disguised as ordinary noise.
In this article we will look in detail at what exactly happens in the tank at different stages, how the filtration system works and why it is important to pay attention to the behavior of water. You will see how the rocker arms rotate and how dirty water is turned into clean water through a complex system of filters. This knowledge will become the foundation for the competent operation of your equipment.
Physics of the process: how water reaches
The basic principle of operation of any dishwasher, be it a budget one Indesit or premium Miele, is based on the circulation of water under pressure. The video clearly shows that water does not just pour from above, but is thrown out at great speed through special holes in the sprinklers. It is the reactive thrust force that causes the rocker arms to rotate, ensuring uniform coverage of the entire internal surface with jets.
The pressure in the system is created circulation pump, which constantly moves water from the pan back to the sprinklers. If in the recording you notice sluggish rotation of the blades or lack of rotation of one of the rocker arms, this is a direct sign of clogged injectors or a malfunction of the pump unit. The efficiency of washing directly depends on how freely water flows through the channel system.
It is important to note that the water jets have a different trajectory and pressure depending on the selected program. In the “Intensive washing” mode, the pressure is maximum, which allows you to knock off burnt-on food residues. In delicate modes, the pressure is reduced so as not to damage the fragile glass, but the exposure time of the cleaning solution increases.
The water distribution system is designed to minimize the formation of “dead zones” where the jets do not reach. However, if you load the machine incorrectly and block the water path with large pots, the efficiency of the process will drop sharply. Video recording helps to understand why the instructions prohibit placing bulky items in the center of the lower basket.
Stages of the wash cycle: from soaking to final rinse
The full operating cycle of a dishwasher is a sequence of strictly defined stages, each of which solves a specific problem. In the video recordings from the inside, the filling phases, when water noisily enters the chamber, and the active mixing phases are clearly distinguishable. First, there is a pre-rinse with cold water, which removes the main large contaminants.
This is followed by the main washing stage, where the water is heated heating element up to a temperature of 50-70 degrees Celsius. At this moment, the dispenser is connected, and concentrated gel or powder falls into the water. The hot environment activates the chemical components, allowing them to effectively dissolve fats and protein compounds, which is especially important for dried food scraps.
Temperature conditions of different programs
In Eco mode, the temperature can reach 50°C, but the cycle lasts 3-4 hours to save energy. The “Auto” mode automatically determines the degree of contamination and selects a temperature from 45 to 65°C. The “Cotton” or “Intensive” program heats the water to 70-75°C to disinfect and remove difficult stains.
After the main wash, a rinsing process follows, which can be repeated several times. The water is drained through a drain pump and the tank is filled with clean water, often with added rinse aid. Rinse aid reduces the surface tension of water, so it does not collect in drops, but flows down into a thin film, ensuring dishes dry quickly without streaks.
The drying stage completes the cycle, which is implemented differently in different models. In cars with condensation drying The hot walls of the tank give off heat to the dishes, causing moisture to evaporate. In models with turbo drying a special fan is turned on, which drives hot air through the chamber, speeding up the moisture removal process significantly.
The role of the filtration system in the cleanliness of dishes
One of the most important components that users often ignore is the filtration system. The video from the inside clearly shows how water flows to the bottom and passes through a coarse mesh filter. Its task is to retain large particles of food, bones and other objects so that they do not get into the circulation pump and clog the thin sprinkler nozzles.
Modern dishwashers are often equipped with a two- or three-stage filtration system. The first level retains large fractions, the second - small ones, and in some models there is also a self-cleaning filter that grinds food debris into a fine suspension, which is safely removed with the drain. If this mechanism is not working properly, the video will show cloudy, dirty water circulating through the tank.
☑️ Checking the filtration system
Clogged filters are the most common cause of poor cleaning performance. If you see in the video (or hear from a change in the sound of operation) that the water is circulating poorly and there is a residue on the dishes, the first thing you need to do is check the filter element. Regular cleaning of this part prolongs the life of the pump and ensures perfect cleanliness.
In addition to mechanical cleaning, some advanced models use chemical filtration using ion exchange resin, which softens the water. This prevents the formation of scale on heating elements and improves the effectiveness of detergents. A video of the operation of such systems shows the absence of white marks on the glass even with high water hardness.
Diagnosis of faults by visual signs and sound
Analysis of video recordings of the operation of a dishwasher allows you to identify hidden defects that are not visible during normal operation. For example, if one of the rocker arms rotates jerkily or stands still, this may indicate that its injectors are clogged or the axle bearing is broken. Visual inspection can help differentiate a water problem from a mechanical problem.
The sound also carries important diagnostic information. A uniform hum of the pump is a sign of normal operation. The (appearance of) grinding, whistling or intermittent humming often indicates that a foreign object has entered the pump impeller or the beginning of destruction of the motor bearings. Paying attention to these signals in a timely manner will (help avoid) costly repairs.
⚠️ Attention: If you notice that the water in the tank rises above the normal level and begins to overflow the edge of the filter, stop the program immediately. This may indicate a clogged drain hose or a faulty drain pump, which could lead to flooding in the kitchen.
Another visual marker is the formation of foam. If the video shows a lot of foaming, this is a sure sign of using the wrong detergent (for example, hand wash gel). Foam can disrupt the operation of the circulation pump, since it is designed to pump water, not an air-foam mixture, which leads to a decrease in pressure and washing quality.
Comparison of washing technologies: classics versus innovations
Different manufacturers use different engineering solutions to improve cleaning quality, and this is clearly visible in the comparison videos. The classic design with two rockers (lower and upper) provides a basic level of cleanliness. However, modern models introduce additional elements, such as a third rocker in the upper part or an intensive washing zone in the lower basket.
Technology Zone Wash or similar solutions allow you to increase the water pressure in a certain part of the chamber. In the video it looks like a more powerful and frequent pulsation of jets in the selected sector. This is especially useful when you need to wash (a little) heavily soiled dishes without waiting for the whole machine to be filled.
| System type | Number of rocker arms | Water pressure | Efficiency |
|---|---|---|---|
| Basic | 2 (bottom/top) | Standard | Suitable for daily tableware |
| Improved (3 in 1) | 3 (additional at the top) | Increased | Better coating for glasses and cups |
| With zone washing | 2 + nozzles | High (in zone) | Ideal for baking trays and saucepans |
| With turbo dryer | Depends on model | Standard | Excellent plastic drying |
Innovative systems such as AquaIntensive or PowerScrub, change the pressure and direction of the jets in real time. The video shows how the machine first powerfully sprays the dishes and then switches to soaking mode. This dynamics makes it possible to remove contaminants that are immobile by nature, such as dried mashed potatoes or egg yolks.
To check that the water is distributed evenly, run the machine empty with clear sides (or through an inspection window if there is one) and place dry paper towels on the shelves. After a short cycle they should be evenly moistened.
Influence of water quality and detergents on the process
Water quality plays a critical role in the efficiency of the dishwasher, which is clearly visible in the contrasting videos. Hard water leaves a whitish coating on the glass and walls of the tank, which over time turns into hard scale. Usage regenerating salt allows you to soften the water inside the machine, preventing these problems and protecting the heating element.
Detergents also behave differently. All-in-one tablets dissolve gradually, providing action at different stages of the cycle. Gels and powders may dissolve faster, which is important to consider when choosing a program. In the video you can see the difference in foaming and water clarity when using different types of chemistry.
⚠️ Warning: Never use regular liquid dishwashing detergent by hand in the dishwasher. They create excess foam, which can damage the electronics and pump, as well as cause leakage at the door seal.
Rinse aids added to a special compartment perform the function of final polishing. They not only remove stains, but also promote faster drainage of water, which is especially important for plastic dishes, which dry worse than glass. Without the rinse aid, the video would have shown many small droplets congealing on the surface.
An ideal washing result is achieved only by a balance of three factors: proper equipment, properly selected detergent and optimal water hardness.
Frequently asked questions (FAQ)
Why does the video show that water remains in the tank after the end of the cycle?
A small amount of water in the pan (usually in the filter area) is normal. It is necessary to maintain the tightness of the seals and prevent the pump from drying out. However, if the water is above the bottom level or in the dish itself, this is a sign of a blockage or malfunction of the drain.
Is it possible to run the dishwasher without the top rack to take a video?
Technically, it is possible to start the car, but it is strictly not recommended to do this without special knowledge. Water will splash randomly, and the seal or electronics may be damaged due to moisture ingress. In addition, this will upset the hydraulic balance and the pump may run dry.
How often do you need to clean the filters for the machine to work like in the video?
It is recommended to wash the coarse filter under running water after each washing cycle or at least once a week. Deep cleaning using a brush and detergent should be done once a month to remove grease deposits that do not wash off with water.
Why does glass become cloudy after many washing cycles?
This phenomenon is called "glass corrosion" and is often irreversible. It occurs due to too high water temperature, excess salt or aggressive detergents. To slow down this process, use lower glass temperature settings and high-quality rinses.
Is it harmful to open the door frequently during operation to check?
Frequently opening the door interrupts the cycle, resets the temperature and can overfill the pan with water, leading to an emergency overflow. In addition, this disrupts the algorithm of the electronics, which can restart the program again, which will increase the consumption of water and electricity.
