The operating algorithm of the dishwasher involves loading dirty dishes before starting the washing program. Then the door closes, the lock is activated and the washing process begins. But there are situations when, after starting the machine, it urgently needs to be supplemented with an additional batch of dirty dishes. In this case, some users, without thinking, try to open the machine door to reload. In addition, there are very inquisitive children who are extremely interested in seeing how the washing process works? And the door makes it difficult to see it in detail. And there is a desire to look inside.

Fault repair
It happens that simple carelessness can damage a new device. If the damage to the door closing mechanism was caused by careless handling by the user, you can try contacting a repair service center to have this problem resolved. The same applies to mechanical damage to the hinges. The service center will have to identify the faulty element and replace it with a new one. As for the hinges, repairs can take quite a long time. The reason for this may be the lack of spare parts. Such a part rarely breaks and few suppliers keep it in stock. The remaining parts are most often in stock.
If the reason for the failure of the door fastening system is natural wear and tear, then it does not always make sense to carry out repairs. These parts rarely break and the car is most likely already old. The search for spare parts and the price often make repairs impractical.
The door closes itself
Other reasons for the door closing on its own most often do not require repair. This can be with the door ajar up to 30 degrees. In this position, the spring will act as a closer and slam the door. Also, you should not pay attention to such things as if you bought a new built-in PMM, but have not yet hung a facade on it. The fact is that the manufacturer includes the weight of the panel in the weight of the door, and until the facade of the required weight is screwed on, fixation in the lower position will not occur. This also applies to the situation when, when choosing a facade, the weight value specified in the instructions was neglected. If it is less than necessary, the door can also close on its own.
In some models of built-in dishwashers, after installation and assembly it is necessary to adjust the spring tension level. If this is not done, problems may also arise with fixation in the required positions.
Door closing mechanism
The door closing mechanism helps the user to lift it, locks it in several positions (open, 45 degrees and closed), and also acts as a closer when closing. The details of this mechanism allow you to open and close the door more smoothly without damaging the elements of the device. This unit consists of several elements: a spring, a cable, a holder, hinges and a closer, as well as elements for fastening one element to another.

Damage to hinges and closing mechanisms
Damage to the door hinges can also cause the mechanism to not work properly. If there is skew or play in the hinges, the door may open lower than it should or may not close all the way. Natural wear of the hinges over time is practically eliminated, since there is no load on them when using the machine. Most often, hinges can be damaged mechanically when the door is opened suddenly or if pressure is applied to the door in the open position.
The PMM door falls
It is also not uncommon for situations when, having opened the dishwasher, you have to hold the door so that it smoothly lowers all the way and does not fall. This situation indicates that the closing system is not coping.
This may be due to the façade being too heavy. If you know its weight, look at the operating instructions for the PMM and check whether it is suitable for you. If not, it is better to replace the facade or remove it altogether. If everything is in order, it is worth adjusting the cable tension screws. Only now you need not to weaken, but to tighten the system.
If this does not help or it is no longer possible to tighten the cables, replace the locking system. Most likely, your cable has burst or the spring has broken, so if possible, purchase a more powerful spring and closer.
Dishwasher operating hours
The operating modes and operating time of the dishwasher vary from dishwasher to dishwasher. As a rule, expensive models have an economical wash mode, in which the operating time and consumption of water and product are reduced. In general, machines wash dishes for no more than an hour and a half. Therefore, the operating time of the dishwasher depends on the program you install.
For example, the operating time of a Bosch dishwasher does not exceed two hours: when the unit finishes washing, it beeps. I must say that all models of machines emit signals - this is very convenient when you are busy with your own business, for example, in another room.

Why do you need to lock the door in the open position?
First of all, this makes it easier to unload and load the dishwasher, since you don’t have to hold the door to prevent it from slamming or falling. In addition, when left slightly open, the device dries faster without the appearance of unpleasant odors and mold after the cycle is completed. Finally, with the door open and locked, it is easier to perform maintenance and servicing tasks, such as cleaning the filters.
Types of problems
Dishwasher owners face two common problems related to door locking. Sometimes it closes spontaneously instead of remaining locked in the open position. But the opposite is also possible - the part goes down. Accordingly, the causes of malfunctions are different.
Damage to the lifting mechanism
In order for the door to move smoothly and lock in a certain position, manufacturers install several parts at once. The mechanism that powers the system and is responsible for fixation includes springs and a special tension cable, fasteners and hinges. There is also a closer that makes sure that the movement is soft, quiet, without jerking or flapping.
During operation, all elements of the mechanism bear quite a noticeable load. Therefore, sooner or later, they wear out. So if the door does not freeze in the desired position as before, most likely you will have to change the springs or cable, holder or closer. The duration of uninterrupted operation depends on the quality of the equipment and components. For example, if the model has a rope cable, it will fray relatively quickly.
Facade too heavy or light
Sometimes the door falls or closes spontaneously if the manufacturer's specifications are not met. In the instructions, he usually indicates what the acceptable façade standards are. If you deviate from these parameters, problems with the door arise.
Damage to hinges
Sometimes the mechanism works, but with malfunctions. For example, the door opens and closes poorly, sometimes it locks in place, sometimes it doesn’t, and sometimes the misalignment is obvious. Then you can suspect problems with the hinges.
Most often, their premature wear and breakdowns are caused by violations of operating rules. For example, if you close the door too abruptly, or even hang on it, which children sometimes do. In this case, parts will need to be replaced.
Although repairs seem to be the best way out of the situation, it doesn’t always make sense to invite a professional. If the dishwasher has served faithfully for many years, then it is likely that not only the elements of the mechanism responsible for fixing the door have worn out. And not a single repair organization will give a guarantee that the device will work for at least a few more years after replacing the hinges or closer. Unfortunately, it is not uncommon for parts of questionable quality to be used for repairs. You can only count on long-term operation when purchasing a new device.
Cleaning the circulation pump
The dishwasher pump is one of the main elements.
It provides forced circulation of water or cleaning solution through the internal lines of the device. This is done to save water, which changes only when you change the operating mode: pre-soaking, washing dishes or rinsing. During one stage of operation of the dishwasher, water circulates in a closed circuit. If the filter is damaged or incorrectly installed, there is a possibility of solid particles entering the water circuit, which can lead to jamming of the circulation pump blades. If the quality of dishwashing deteriorates significantly, it can be assumed that the circulation pump is not performing its functions and needs maintenance, or rather, the fragment that is interfering with the normal rotation of the blades will have to be removed.

But not everything is so simple, since there are two types of design of the unit: with the ability to access the pump blades and without it. You can find out this point in the instructions for the dishwasher. If it describes the procedure for removing the protective covers, then the user has the opportunity to independently get to the pump impeller and fix the problem.
If the manufacturer directly prohibits the dismantling of protective covers and casings, then to eliminate the malfunction you will have to resort to the help of service specialists.
As for the general care of the water circulation system, it is important to understand that during operation, fatty deposits form on the walls of the water mains. They gradually reduce the throughput of the system, the pressure inside it increases, which does not have the best effect on the operation of the circulation pump and is fraught with various breakdowns: from rupture of the system tubes to failure of the pump.
To eliminate this factor, you need to make it a rule to clean your dishwasher regularly (once every 3-6 months, depending on the intensity of use) using specialized products. Only they, coupled with high temperature, are able to remove fatty deposits from the inside of the dishwasher.
Such products are produced in various forms: cleaning liquids, gels, tablets, etc. The logic of their use is the same. In accordance with the instructions for use, place the required amount of product into an empty dishwasher, set the operating mode to the highest possible temperature and start the washing cycle.
High temperature and aggressive chemicals dissolve and wash away all fat from the circulation system into the sewer.
Is it possible to leave the door closed?
Some housewives believe that since the manufacturer has released a dishwasher, it means that it should not only wash dirty dishes, but also perform self-service. That is, no additional maintenance is required. There are other, more rational arguments on this score. Here's how users justify keeping the PMM door permanently closed:
- The machine was tested at the factory before delivery to the store, so there may be water left inside. Nothing bad happened?
- Washing is carried out at high temperatures with chemicals, so you should not be afraid of the appearance of mold and mildew. Moreover, the remaining powder will only dry to the walls if you keep the door open.
- Buyers did not choose a compact machine so that it could take up space in the kitchen with a door. And there’s nowhere to turn around; the manufacturer probably foresaw this moment.
- There is no need for unnecessary electricity consumption, because the light comes on when opened.
Of course, you can keep the bunker closed if you so choose. But what is better for technology and health? Let's consider the second point.
