Reasons why your dishwasher doesn't clean well. Why is my dishwasher bad at washing dishes? Dishwasher does not wash pots well

She started washing dishes badly, there is no need to rush and send her to retirement. Perhaps everything can be fixed.

This article talks about the main reasons why your dishwasher has stopped working as it should. Here are the problems caused by:

• misuse;
• problems not related to mechanics;
• breakdowns mechanical parts.

The article also gives advice on what to do in such situations.

Incorrect operation

If you do not use the dishwasher according to the instructions, it will most likely respond by washing dishes poorly. Below are four reasons that can cause a negative reaction from a machine.

Why the dishwasher doesn't work:

• Leftover food and dried food. If stuck tomato peels, congealed sauce, and even more so fish/meat bones are not removed from the dishes before washing, the equipment will not cope with the task as it should. Manufacturers are almost the first to warn that it is necessary to remove food residues before loading. Dried sauces and cheese need not be removed from the plates only if the dishwasher is equipped with a pre-soak mode (like the SN 278I03 TE from Siemens).

• Incorrect mode selection- another common occurrence. For example, users often set an economical program or a quick wash. But such modes are suitable for not too dirty dishes, for example, tea and coffee cups, non-stick pans where eggs were fried without oil. If the items are stained with something greasy, you need to choose a long mode in which the machine will heat the water strongly.

• Machine overload. If your automatic dishwasher doesn't do the job properly, it may be because there's too much stuff in it. Equipment overloaded with objects is not capable of washing more per cycle than stated by its creators. To solve the problem, next time you should try not putting a lot of pots or other utensils.
• Incorrect use of detergents. If the owner of the appliance has chosen the wrong cleaning agent (tablets, salt or rinse aid) or simply did not calculate the amount, this can cause two situations: the dishwasher will not wash properly or will not rinse well.

Everything is done according to the instructions, but the device still doesn’t wash properly? Most likely there is a problem within. If it’s not mechanical, then you can fix the problem yourself.

Non-mechanical problems

The equipment may not be able to cope with the work various reasons. If the problem is not in mechanical parts, then there are only two most common ones:

1. scale;
2. blockages.

More details about how this affects the quality of washing and what should be done are discussed in the table below.

Advice: if you need a compact but roomy option, you should take a closer look at. It does not take up much space, and can wash a dozen sets of cutlery at a time.

If the filters are clean, there is no scale, and the machine is used as it should, but it still doesn’t wash well - perhaps there is a more serious malfunction and it is related to a mechanical failure.

Mechanical problems

Mechanical problems are another reason why equipment becomes difficult to clean. Everything is more serious here than in previous cases. So what could have happened?

The heating element is broken

A heating element - important detail dishwasher, because without it the water will be cold, which means that dirt from the dishes will not disappear. This part of the equipment suffers from scale more than others, and therefore simply deteriorates over time. What can you do here - just go to the technician, just replace it.

Advice: In order not to bring the problem to repair, it would be good to periodically call.

The circulation pump has failed

The pump that allows water to get inside the chamber may also fail. It is not difficult to understand that this is the problem - the washing program simply will not work, because water will not flow inside the car. Repairing a part yourself is a lost cause. Only an experienced repairman can correct the situation.

The sprinkler does not rotate - the impeller is broken

In order for water sprayers to fulfill their purpose, the equipment is equipped with an impeller. It is a special mechanism that rotates the rocker arm where the spray parts are located. If the impeller breaks, then the sprinklers (or one of them) do not work. As a result, the dishes are poorly washed: they remain dirty or have a soapy residue.

Thermal relay malfunction

This element is a water temperature meter. He reports the heating power to the programmer, which in turn orders the heating element to heat. If the temperature sensor is broken, it does not provide data to the programmer. This is why dishes are washed poorly: the water simply does not heat up.

Advice: if you need a model that can dry quickly, it’s hard to find a better one. It has an intensive drying program, and also convenient electronic control. In addition, it saves electricity.

Software problem - the mode/dishwasher control module has failed

As mentioned above, the control module commands all technical units of the equipment. It is he who gives the order to heat and fill/drain water. If the programmer breaks down, the dishwasher either works incorrectly, begins to take on a life of its own, or stops working altogether.
Correction of all listed mechanical breakdowns must be entrusted only to good master. He will diagnose the car, find the cause of the problem and fix it. Doing something at home in these cases is very undesirable: you can only aggravate the problem, and then waste more money for repairs or even have to buy a new dishwasher.

If the reason for the dishwasher’s poor behavior is improper use: too much detergent, incorrect mode, or very dirty dishes, then you can easily fix this problem yourself. If the equipment cannot cope with the job due to scale or clogged filters, you can also figure it out yourself. It won't be difficult to clean it. But with problems caused by the breakdown of mechanical parts, everything is more complicated. The only thing that can be advised in this case is to call a professional. He, like a doctor, examines, finds the cause and cures.

The presence of dishwashers in the kitchen will greatly facilitate the work of any housewife. However, no matter how high-quality and expensive such equipment turns out to be, due to improper operation or other reasons, it may not cope with its main tasks. So what should you do if your dishwasher doesn’t wash dishes well, why do situations like this happen?

The most common reasons for poor cleaning of dishes in specialized equipment: how to eliminate them?

If, after cleaning in dishwashers from Bosch, Electrolux or other brands, stains, food residues or other contaminants remain on the cutlery, then we can talk about both serious malfunctions of the unit and completely removable defects.

If the question arises about why a dishwasher does not wash dishes well, then most often we can talk about completely banal reasons:

• Presence of dried food and significant food residues. If you don’t remove all this from the cutlery in advance, then you shouldn’t even count on perfect cleaning of the dishes. This rule is mandatory for all manufacturers, both Bosch and others. Therefore, it should be observed first of all.

• Incorrect operating mode of the unit. Too short or economical dishwasher operating programs are intended exclusively for minor dirt. But dishes with greasy residues need to be used more. temperature regime and long washing cycles.
• Significant overload of equipment. Dishwasher may not cope with its main task due to the installation of more dishes than provided by the manufacturer. The next time you wash, you should try loading fewer appliances into your appliances. Insufficient cleaning at the top can also be caused by improper loading. kitchen utensils. Incorrectly positioned devices may interfere with operation important elements technology. In this case, you will need to reboot the equipment in accordance with the manufacturer's recommendations, as shown in the photo.
• If the unit does not wash dishes well, the reason for this may be an incorrectly selected or low-quality detergent composition. In this case, changing the product or using less of it will correct the situation. Today there is great amount specialized products that are specifically designed for use in dishwashers. These can be either liquid gels and rinses, or multifunctional tablets.

In the case where all the above attempts to correct the situation did not help, the dishwasher from Bosch, Electrolux and other manufacturers continues to wash dishes poorly, which means that you will have to take a closer look at the functioning of such a unit. Certain reasons for such poor quality work may be associated with intensive use of technology. But when the right approach and they can be resolved on their own.

For what other reasons does technology fail to cope with its tasks?

Frequent and prolonged use of the dishwasher can also cause it to malfunction. In this case, the equipment may malfunction due to more serious faults:

• Scale formations on the unit. This process is especially treacherous for any dishwashing equipment. Scale may appear due to the increased hardness of the water used for washing (and this is even with the constant use of special softening compounds). It is almost impossible to determine its presence on the plastic elements of the device, but all internal metal parts with prolonged use they begin to become covered with such a dangerous coating. Having affected the sprinkler, scale prevents water from spraying properly, which in turn leads to poor cleaning of cutlery. To correct this shortcoming, you will need to add it to the dishwasher instead of the usual cleaner. citric acid, after which it starts at maximum temperature in idle mode.

• The appearance of blockages. If a Bosch dishwasher does not wash dishes well, food particles, stains and other contaminants constantly remain on it, then we can talk about the formation of blockages in the appliance. Most often, this problem occurs with fine and coarse filters. If this is the reason, then you should first check the condition of the filter. The most the best option It will be necessary to clean such an element after each dishwashing cycle.

If you still haven’t been able to determine on your own why your dishwasher doesn’t clean well, then it’s best to seek professional help. IN certain cases We may be talking about more significant breakdowns that require replacement or repair of individual spare parts.

More details about possible reasons The video will help you find out about poor cleaning of dishes and how to eliminate them.

The quality of washing depends on several factors. But usually users do not pay attention to the operating rules, which is why the device begins to work worse and worse. Among the reasons why your dishwasher has become difficult to wash dirty dishes:

• untimely cleaning of parts;
• errors during operation;
• poor-quality cleaning products or their incorrect dosage.

Dishes may remain dirty if the machine is not used correctly.

If your dishwasher does not wash dishes, first of all, analyze how you use the unit. Among the most common mistakes you can note:

• loading more dishes than allowed;
• choosing the wrong mode;
• improper placement of plates and glasses in cages.

Before turning on the dishwasher, you should carefully read the instructions. Dishes should be placed so that they do not interfere with the operation of the spray arm or block access to the detergent. In addition, the plates that are located on the lower level should not interfere with the passage of water to objects higher up.

Place dishes in the dishwasher correctly

The more dishes you put in the dishwasher, the worse they will clean. If you overload the machine, you will have to wash the dishes again after washing. Another mistake is setting a mode that does not correspond to the type of pollution. If you need to wash a frying pan and you turn on the glass mode, the utensil will remain dirty. A quick wash will also not remove grease remaining on pots and plates. If your dishwasher is having trouble cleaning dirty dishes and you don’t know what to do, first read the instructions. It describes all types of possible downloads, modes and other useful information.

If stains appear constantly on plates that have been in the dishwasher, the unit most likely needs to be cleaned. Any model must be regularly inspected and the condition of the following parts checked:

• sprinklers;
• mesh filter for food;
• heating element and tank;
• filling filter.

Check the instructions to understand where the filter is located to collect food particles. If the appliance does not wash dishes, it is most likely dirty. Usually the element is located at the bottom of the unit and looks like a fine mesh. It needs to be washed every ten days.

Washed utensils in the dishwasher and by hand

If the water is hard, keep an eye on the filter core - it can be seen at the inlet of the unit. When the filter becomes clogged, the water pressure weakens. This is another reason why the machine does not wash dirty dishes.

The heating element and tank may suffer from scale. To prevent its occurrence, buy the appropriate product. It is important that it matches the type of dishwasher you have. Periodically turn it on in idle mode, adding a composition that removes scale.

To prevent internal elements from rusting, wipe them with a dry cloth after all procedures.

If your dishwasher has become difficult to wash dirty dishes, one of the ways to fix it is to check the detergent used. If you changed the composition, and plaque and stains begin to appear on your kitchen utensils, the reason is obvious. Buy another one and your machine will work much better.

If you always add the same product, but the plates remain dirty after washing, the reasons may be different:

1. The machine does not wash away stains from coffee, tea and lipstick well - not enough bleach. To solve the problem, buy the necessary supplements or change the product.
2. Gray plaque and unsightly stains are a sign of a lack of rinse aid. To solve the problem, adjust its flow.
3. Plastic plates remain greasy - there is not enough grease dissolving agent. To correct the situation, change the composition or add additives yourself.
4. White streaks are observed on the pots - salt powder ends up inside the machine, resulting in a coating.

The cause of problems may be the use of a composition produced to solve other problems. At first everything will be fine, but over time performance characteristics the unit will begin to deteriorate, and then it will fail.

The reason may be poor quality dishwashing detergents.

If there is a residue on the plates, you may have added special salt a long time ago. In such a situation, the ion exchanger breaks down due to hard water, as a result of which the detergent particles dissolve poorly. If you reapply salts, the operation of the dishwasher will quickly return to normal.

If the above measures do not have an effect, the problem may be significant. One possible reason is the failure of some parts:

1. The heater burned out. This element comes into contact with water, so scale forms on it. Over time, the heating element simply burns out. In this case, the water does not heat up, and it is impossible to wash the plates with cold liquid.
2. The sprinkler does not function - as a result, water does not reach all places, and the dishes remain dirty.
3. Broken water turbidity sensor - used only in new models. It controls the quality of the water: if it is cloudy, the washing continues, if it is clean, the process ends. When the device does not work, the machine does not understand exactly when to end the cycle.
4. The thermostat has burned out - it detects the temperature of the water and gives the command to heat it. If there is no signal, it remains cold and the dishes are not washed.
5. The recirculation pump has failed - it provides. If damaged, the device will not work.
6. The control module is malfunctioning - this element is responsible for everything. If it fails, the machine will work poorly or stop completely.

Master repairing a dishwasher

To eliminate the listed faults, you should call a technician or take the dishwasher for repair.

How to wash dishes in the dishwasher

To achieve the desired result, place the dishes loosely so that the water flows down easily. Before loading, remove any leftover food from plates and soak pots and pans first. Regularly check the condition of the sensors, keep all the necessary tools in stock. After each cycle, wipe down the internal elements, and do a thorough cleaning once a week.

When choosing a dishwasher model, be sure to consider the load size. If a lot of dirty dishes accumulate in the house, a compact device will not suit you - an overloaded machine will not be able to wash the dishes.

Treat your dishwasher with care and select carefully detergents, do not violate the operating rules and regularly clean it of dirt, and it will never let you down.

If the BOSCH dishwasher does not wash the dishes, dirt remains on its surface, do not rush to contact a specialist. Perhaps the problem is due to improper use.

Before calling service center, check the following.

• Is the mode set correctly? Perhaps the water temperature and washing intensity do not correspond to the contamination.
• Are you overloading the car? If there are too many dishes, the quality of washing will be poor.
• Do you leave food on dishes? Leftover food should be thrown away, as manufacturers warn.

The reason for poor dishwasher performance BOSCH machines It could also be a low-quality solvent or dishwashing detergent. If you load too little or too much product, the equipment will not cope with the contamination or will not be able to wash away the remaining solution. It is important that a special composition is used. Regular dishwashing detergent will not work.

If everything is in order with the product, and you follow the operating instructions, the problem may be a malfunction of one of the components. It may break:

Errors in the BOSCH dishwasher control system are also possible.

What to do if the dishwasher doesn't clean?

First, make sure you follow the operating instructions. Perhaps this is precisely the problem: you put dishes with frozen food into the machine, overload the equipment, use the wrong mode or the wrong product. If you are a rules-based person, try to figure out what the problem is. In particular:

• failure of the heating element leads to washing cold water. The water simply does not heat up and the machine cannot wash the dishes well. If the heating element is broken, the dishes will be cold;
• Due to a broken pump, the washer does not start at all. Water does not circulate in the system, and the dishes remain dry and dirty;
• a failure in the control unit leads to operational errors - the duration and intensity of washing do not correspond to the selected mode.

Having understood what exactly went wrong, you can more accurately describe the problem to the technician.

What repairs will be required if the dishwasher doesn't clean well?

The type of repair depends on the breakdown. So, it is possible to replace the sensor, circulation pump, heating elements, reflashing the control system, as well as other types of work. The exact cost and duration of repair of a BOSCH dishwasher can only be found out after diagnostics. It is carried out by a master who comes to the call.
