Why are the dishes in the dishwasher dirty? What to do if the dishwasher does not wash dishes well: expert advice

The dishwasher (PMM) is a wonderful assistant for the hostess in the kitchen. It is able to work flawlessly for years and delight its owners with the impeccable quality of washing utensils and its functionality. Sometimes during operation, you begin to notice that the dishwasher does not wash dishes well.

Some of the housewives are dismissive of various factors that affect the quality of washing, explaining this attitude by the fact that the device does its job so well. But if you began to notice white stains, food debris or plaque on the plates, then the cause of the trouble may be:

untimely preventive cleaning PMM details;
improper operation of the machine by the user;
wrong dosage or replacement special means for third-party washing;

Dishwasher like any other Appliances, requires careful maintenance and timely cleaning individual parts and nodes. The following elements are subject to regular cleaning in the unit:

Flushing with PMM using special means should be carried out once every six months. And this does not depend on the frequency of use of the unit.

After each end of the washing program, the appliance should be checked for leftover food, which may be in the tank of the machine or under the door, especially if it is a Bosch dishwasher.

Misuse

The reasons why the dishwasher does not wash dishes well can be in common mistakes use of the unit by the hostess:

user uploads very a large number of crockery and cutlery;
utensils in baskets fit incorrectly;
Wrong washing program selected.

The instructions describe in detail the correct arrangement of dishes in the baskets. PMM manufacturers (Electrolux, Siemens, Bosch) pay great attention to this issue. Therefore, it is recommended that you read these tips carefully before using the machine.

One of the most important rules arranging utensils in a basket is arranging it in such a way that there are gaps between it, and water can flow down without remaining in the plates.

You should also pay attention to the fact that the dishes in the lower basket do not block the flow of water to the upper basket. The stacked utensils should not interfere with the opening of the compartment with the tablet, as well as the rotation of the rocker arms. The more content is loaded, the denser it is. Such tight placement interferes with the good circulation of water and soap solution, and it may remain unwashed.

Another reason why the dishwasher does not work well is the choice wrong program e.g. for washing heavily soiled utensils. This starts a quick wash (in this mode, heating water is coming up to a temperature of 45-50 C °). In this case, with heavily soiled contents with dried food residues, you should not expect high-quality washing (it would be more correct to choose a washing program with soaking). This is also described in the instructions for the unit, which few people read.

In order to make the filter of the machine less dirty, before loading the utensils into the machine, thoroughly clean it from food residues.

Detergent replacement or incorrect dosage

Next possible reasons the fact that the Electrolux dishwasher and the like - Bosch, Hansa and others - do not work properly can be directly related to the use of detergents. More often this problem occurs due to the change detergent on the low quality or fake. This trouble is easily eliminated if you return to the previously used tool. Also, you can try to pick up a detergent until you find the best quality and effective option. If you did not change the detergent, and the dishwasher sometimes began to wash dishes poorly, the problem may be wrong dosage facilities.

If the user refuses to use a special salt that restores the ability of the ion exchanger to soften water, then over time (if the hardness of the water in the line is high), it becomes clogged and fails. The use of complex tablets “3 in 1”, with very hard water, is not able to replace salt and it still needs to be added to the unit.

When to call the wizard

Above, the reasons for poor dishwashing with a dishwasher were considered, which are obvious and can be eliminated without contacting service center. But there are times when you can’t do without calling the wizard.

These faults should only be repaired by a qualified technician with knowledge and experience in this type of equipment. Only the master is able to diagnose and repair the device. If you try to do this on your own, you can get a disastrous result, and even a specialist will not be able to correct the consequences of your actions.

Washing dishes perfectly by hand takes a lot of time and effort. That is why the dishwasher is one of the most desirable household appliances for every hostess, its presence greatly facilitates life.

But how frustrating is the fact that the beloved “assistant” began to perform her main task poorly, began to wash the dishes poorly! Why is this happening and how to restore the normal functioning of the dishwasher?

An unsightly picture in the form of dirty, with food remnants, napkins and soap bubbles, dishes at the end of the washing cycle is most often the result of wrong dishwasher operation. Therefore, if your machine, as it seems to you, is broken, do not rush to panic!

Before calling to your house experienced craftsman All Repair24, which will surely cope with any malfunction of the dishwasher, re-read instructions To her! Check if you are doing everything right, whether you are following the manufacturer's instructions.

Most common mistakes owners of dishwashers, leading to the fact that the machine washes poorly:

Remains of food are not removed from the dishes before they are loaded into the machine.
Too many dishes are being loaded into the dishwasher.
Too little or too much detergent. Also, the problem may be the low quality of household chemicals.
Wrong mode selected. How dirtier dishes, the longer the wash cycle in hot water must be implemented. It is better to choose economical washing programs only if the dishes are not very dirty.

If you have removed all the remnants of food and other debris, loaded the dishes and detergent exactly as much as necessary, selected the washing mode correctly, and as a result the dishes are dirty again, first of all check if they are clogged coarse and fine filters.

Did you know that dishwasher manufacturers recommend checking and, if necessary, cleaning these filters every time after a wash cycle is completed? How long have you been doing this?

If you always do everything right and, in principle, do not make the mistakes described above, it means that failures in work are due to other negative factors. And the main one is "hard" water.

Even with the regular use of special water-softening rinses, it negatively affects machine parts, leading to the formation of scale on them.

As a preventive measure, as well as in order to rid the machine of scale, from time to time you need to arrange cleaning for it. citric acid. To do this, the acid is poured into the detergent compartment and the washing mode is started with the maximum temperature. Naturally, at this time the dishwasher should be empty.

However, it may be that the scale has already done its job and completely disabled some parts of the dishwasher. In this case, you definitely cannot do without the help of a master!

So, a dishwasher that does not clean dishes well may need the following: repair types:

Replacement sprinkler impellers. The impeller is a mechanism that rotates a rocker arm with sprinklers. If the spray arms do not rotate, water does not reach the entire surface of the dish and it does not wash properly.
Replacement temperature sensor. The temperature sensor or thermal relay measures the water temperature and transmits the information to the software module. If the temperature sensor is broken, information is not transmitted and the water does not heat up, respectively, remaining cold, does not wash the dishes.
Replacement circulation pump. This pump pumps water into the dishwasher. When it is faulty, there is no water in the dishwasher, respectively, washing does not start.
Replacement heating element. TEN - a water heater, the element most susceptible to scale formation. At a certain point in time, the heating element may simply “burn out”, the water will stop heating, the dishes will not be washed out normally.
Replacement or "flashing" software module. The software module is the “mind” that sends all commands to the technical components of the dishwasher. If it is not working, washing is carried out incorrectly or does not occur at all.

If your dishwasher is in the expensive category, it is most likely equipped with water turbidity sensor. A malfunction of this sensor can also lead to the fact that the machine washes poorly. In this case, it is necessary to replace the water turbidity sensor, which will be quickly and efficiently carried out by the VseRemont24 master, just like replacement any other of the above details:

heating element,
module,
temperature sensor
impellers,
pump.

Instead of the old, broken one, you will be installed exactly the same, “native”, but a new and properly working part of the dishwasher. The VseRemont24 master will provide you with a guarantee for it, just like for all types of work carried out by him.

The cost of repairs depends on the complexity of the repair, as well as the make and model of the dishwasher.

Masters of VseRemont24 have extensive experience in working with dishwashers various brands and models. Therefore, within a couple of hours after the arrival of the master to your home at any time convenient for you, the whole necessary repairs will be implemented. Your indispensable “assistant” will again wash the dishes to a shine and creak of cleanliness!

Housewives often have to face the problem when their expensive and reliable dishwasher does not wash well, ceases to cope with the functions that it performed five plus yesterday. Not always the reasons for this situation are associated with serious technical problems. In the ranking of circumstances that limit the functionality of these devices, they are usually in the very last place.

Summarizing reviews of breakdowns, their sources can be ranked in the following order:

incorrect operation;
untimely cleaning and maintenance;
technical issues.

Users often neglect the requirements of manufacturers, do not pay attention to instructions and operating manuals. Awareness of their relevance comes only when their dishwasher began to wash badly. Usually these are five main mistakes:

neglecting the preliminary cleaning of utensils from food debris;
violation of the order of placement in the baskets;
loading in excess of the number of sets;
wrong choice of washing modes;
errors in the use of detergents.

Preliminary cleaning of utensils

Dishes should be cleaned of food residues before being placed in the machine. Otherwise, it will accumulate in the washing compartment, clog the filter, and adversely affect the operation of the sprinkler. A natural result of such use is complaints that the dishwasher does not wash well.

Placement order

Any, even the smallest dishwasher, is equipped with metal baskets, which are divided into zones for certain types of utensils.

Placement takes into account the direction and intensity of water flows, which allows you to thoroughly wash out pollution. On the contrary, its violation does not allow the dishes to be washed with the required level of quality.

Laying in different models may have peculiarities, but in general it will follow the order shown in the table.

Excess number of sets

Depending on the type, washing devices are calculated for a certain number of sets:

in compact models, from 4 to 6 are loaded;
narrow models are calculated for 9 sets;
full-sized can take up to 12-17.

Based on the number of sets, the manufacturer determines the optimal water consumption and other washing parameters. The stacking density increases, there are problems with water splashing and detergent access to the compartment. All this does not allow us to expect that the dishes will be washed completely and with the required quality.

In some cases, housewives try to compensate for the overload by restarting or using intensive washing, which reduces the working life of the device.

Mode selection

Different models may have a different number of modes, but the standard set is the same for all. This is the normal mode, enhanced and delicate.

Do not be surprised that the dishwasher washes poorly if the delicate (accelerated) mode of operation is selected for heavily soiled utensils. At a temperature of 45 ° C, the device simply cannot cope with dried food residues, grease and other contaminants.

Detergents

Dishwasher malfunctions can create misuse detergents. The instructions from the manufacturer indicate a list of tools that can be used with a particular model.

An attempt to use their universal counterparts or detergent for other models will not allow you to get the desired effect. Deficiencies in the operation of the device can be caused by non-compliance with the dosage.

Cleaning and maintenance

Another reason why the dishwasher does not wash dishes well is untimely care. In the course of work, especially with large quantity sets, food residues accumulate inside the device. They settle on the spray arm, internal system filtration, contribute to the formation of scale and blockages.

Poor quality tap water with a large number of small particles can clog the inlet filter. The only way to prevent such problems is to regularly clean the filters and thoroughly rinse the inner inner compartment.

technical issues

If there are no complaints about the operating procedure, and the dishwasher still began to wash poorly, more serious problems are likely associated with the breakdown of structural elements. In branded, expensive devices, such as Bosch, Electrolux or Hansa, they occur during many years of intensive use and are the result of natural wear and tear of individual components and mechanisms. Among the reasons for the decline in the quality of washing, experts usually mention:

heater failure;
malfunction of the circulation pump;
problems with the spray arm;
failure of the temperature sensor;
failure in the software module.

Heater failure

One of the key design elements that provides water heating up to desired temperature. More than other elements are prone to scale formation, it can burn out during prolonged use. This causes a lack of heating and the inability of the device to function normally.

Circulation pump malfunction

If this mechanism fails, the water supply for washing is not possible. In the latest models, the heater and pump are installed in one unit. In case of failure, their repair is impractical, the breakdown is eliminated by replacing the unit as a whole.

Spray Arm Problems

This problem occurs when the impeller that rotates the rocker is defective. In the absence of rotation, water is not distributed inside the compartment. The dishes are not washed with the desired quality.

Thermal sensor failure

This element controls the temperature of the liquid, ensures its increase to normal or decrease. Its failure means non-compliance with the required temperature regime, which means problems with washing. Eliminated by replacing with a new part with similar characteristics.

Fault in software module

Replacement is better to solve the problem with the software module. Responsible for transmitting commands to the mechanisms and components of the structure. Its failure will not allow the machine to reach the desired mode of operation and provide the appropriate level of processing.

All of the listed malfunctions of the technical plan are best eliminated with the help of an invited specialist. When repairing on their own without proper experience and qualifications, the likelihood of new breakdowns is high.

After the end of the washing cycle, poor-quality washed dishes were found behind the hopper door - with plaque, food residues or soap suds? Familiar situation? Why did this happen and why does the dishwasher wash dishes poorly? The reasons for this may be simple to the point of banality, but a serious breakdown is not ruled out. Let's take a look at everything in detail.

PMM does not launder: incorrect operation

If the dishwasher has become poorly washed, first of all it is necessary to exclude factors that are not related to the breakdown of parts and systems. The reason for this may be a violation of the rules of use:

There is food on the plates. If you are accustomed to saving dishes all day long and do not brush off the leftover food from them, then you can forget about high-quality and efficient washing forever. The manufacturer warns about this in the user manual - take a look at it if you don't believe it.

Wrong program. If you have loaded a large batch of heavily soiled dishes and have selected the short or economy setting, don't be surprised if the machine doesn't clean well. These cycles are designed for washing lightly soiled dishes and utensils, as well as for refreshing dishes. In other cases, you need to choose intensive and high-temperature cycles.
Bunker overload. The machine does not wash the plates if the baskets are crammed full of them. Unload the boxes, observing the distance between the dishes - perhaps this is the reason.

Detergents. Another reason why the dishwasher stopped washing is the wrong selection of detergents or their required volume. Adjust the dose of powder or detergent, add rinse aid, or completely replace the products in your arsenal.

If none of the above factors came true and you still end up with dirty or soapy dishes, you need to take the issue more seriously. You will have to understand the structure of the machine or contact the master. Although this is an extreme measure, most problems at an early stage can be solved without contacting a service center.

Other Issues Requiring Immediate Resolution

The reasons listed below are often not related to a violation of the terms of use, or are related, but indirectly:

Limescale or simply scale. This is main enemy technology that works with hot water. It's all because of the impurities that make tap water hard. Often, even special softeners and regenerating salt do not soften the impact of water on the inside of the dishwasher. The worst thing is that the raid is not visible - it is inside the PMM and slowly causes the car to break down. If scale appears on the impellers (sprinklers), then the water is sprayed much worse, which affects the efficiency of washing.

blockages. It is difficult to fully remove all the remnants of food, napkins and other things from the plates - in this case they will have to be washed, but why then PMM? All this rubbish is collected by filters, and also falls on sprinklers. Therefore, if the dishes are slippery and unwashed after a dishwasher, check the filters. It is advisable to clean them after each cycle - this recommendation is even spelled out by manufacturers in the instructions.

If the amount of detergent is chosen correctly, you have thoroughly cleaned the utensils of dirt and cleaned all the filters, but the washing is still bad, it looks like a breakdown. What to do: how to detect and fix the failure? More on this later.

Possible problems: how to fix?

Consider the possible malfunctions in which the PMM may not be able to cope 100% with its main function:

Heating element failure

Each PMM is equipped with a device that heats water to the required temperature. Thermoelectric heater (TEH) is most prone to scale accumulation on its surface. The longer the overgrown heating element works, the sooner it will burn out. After the heater fails, the machine ceases to cope with the main function - and the quality of washing drops to a minimum, since it is difficult to wash something in cold water. In this situation, it is necessary to disassemble the machine body and completely replace the heater with a new part.

Breakdown of the circulation pump

The pump that pumps water into the dishwasher, when it fails, blocks the water supply for the washing process, hence the dirty, cloudy dishes. The way out of the situation is to replace the part with a new original.

Sprinkler wheel problems

The impeller is a mechanism that rotates the rocker with sprinklers. In case of failure, the rotation stops (both one impeller and two) and the dishes are not washed well. The way out is to replace the impeller.

Temperature sensor failure

The temperature sensor (thermal relay) is used to measure the water temperature. The information received by the sensor is fed to the electronic module, which commands the heater to start heating. If the data is incorrect (or not supplied at all), the heating element does not start and the wash takes place in cold water - hence its low quality. The sensor needs to be replaced with a new one.

Malfunction of the control module

The task of the software board is to send commands to all PMM nodes. So, the module controls heating, draining and other processes. In the event of a breakdown, the board does not work correctly, causing a malfunction of the machine. In this case, the module must be flashed or replaced with a new one.

Turbidity sensor failure

This error is only for expensive cars, in the design of which a sensor is provided that controls the turbidity of the water. It sends a signal to the board that if the water is not yet clean enough, the cycle should continue. If the sensor fails, the module does not receive information about the state of the liquid and the wash cycle does not work correctly. It will help to replace the sensor with a new one.
