The dishwasher saves time and effort, but does not always cope with its "duties". If the dishwasher does not wash dishes well, the cause of the malfunction may be incorrect or too active use of the device. In most cases, problems can be identified by yourself, but sometimes you still need the help of a professional and replacement of components.
Incorrect use of the dishwasher
Why is my Bosch dishwasher not washing dishes well? The reasons can be banal (and the same for different brands of equipment):
- overloading the machine (to fix the problem next time, you can try to put less dishes and kitchen utensils with the same amount of detergent);
- food leftovers and dried-on food particles (must be removed from dishes before startingloop);
- wrong mode (short and economical programs are only suitable for light dirt, and fat requires a long cycle at maximum temperature);
- improper use of dishwashing or appliance care products (only special products should be used: tablets and rinses; the manufacturer indicates the recommended amount of chemicals for one washing cycle on the package).
If compliance with the operating rules did not lead to a positive result, then most likely you will have to get to know the internal structure of household appliances better. Some problems appear with the active use of the dishwasher and can also be successfully solved without masters.
Calculation on dishwasher parts
Why is the dishwasher not washing dishes well? The reason is often scale, which appears due to the use of too hard water. Even special softeners recommended by manufacturers do not help. Scale is not visible on plastic parts. Appearing inside, where the components are metal, scale prevents the flow of water with soapy water, which is why the dishes are poorly washed. To fix the problem, you need to pour citric acid into the dishwasher instead of a special detergent, and then run an idle cycle at maximum temperature.
Clogged filters of various cleaning types and sprinklers
Particlesnapkins, leftover food and other small debris that inevitably gets inside kitchen appliances is another common cause. The dishwasher does not wash dishes well in this case due to clogging of the internal coarse and fine filters and sprinklers. You may just need to clean the filters. From now on, you will have to do this quite often - preferably after each wash, as recommended by the manufacturers.
Other possible dishwasher problems
Why is the dishwasher not washing dishes well? In order for the dishes to shine clean, it is often enough to replace the detergent. You should not use the cheapest product from a little-known manufacturer - the quality of such washing powders or rinses is very doubtful. You can try changing the amount of dishwashing powder or rinse aid up or down. This is especially true if white stains remain on the dishes. Leaks can also occur if the lid of the s alt container is loose.
Why is the new dishwasher not washing dishes well? New kitchen appliances are unlikely to have time to become heavily scaled or broken, so the solution to the problem must be sought in something else. Why a dishwasher does not wash dishes well can only be understood from our own experience. You need to try changing the detergent, adjust the dosage, thoroughly clean the drum and filters, put fewer dishes in the basket, or adjust the wash cycle.
Proper caredishwasher
Dishwasher requires regular and careful care. After each cycle, you need to clean the tank from plaque, check the filter and water sprinklers, and at least once a week - clean the main filter installed at the bottom of the tank. After the end of the program, it is necessary to check the appliance for the presence of food particles that may accumulate under the door or in the tank of the machine. With active use, pollution only accumulates, and then the device not only starts to wash dishes poorly, but also an unpleasant smell appears, which is very difficult to remove.
Violation of the rules for loading dishes into baskets
Often the problem is the wrong arrangement of dishes in the baskets. Care must be taken that the kitchen utensils at the bottom of the basket do not block the flow of water to the top. Dishes must not interfere with the opening of the detergent drawer and the rotation of the spray arms. If the contents are too tightly packed, it interferes with the normal circulation of water, so that the dishes may remain unwashed. Manufacturers sometimes give different recommendations (based on the features of a particular device), so the rules for placing kitchen utensils should be read in the instructions.
Technical failures requiring parts replacement
Why is the dishwasher not washing dishes well? Kitchen appliances may not sufficiently clean dishes from dirt or even interrupt the washing cycle for the following reasons:
- breakdown of the water heating device (heating element);
- malfunction in circulation pump;
- breakage of the sprinkler impeller;
- temperature sensor malfunction;
- breakdown of the water turbidity sensor.
Dishwasher water heater failure
Teng is necessary for heating water, therefore, more than other parts, it is prone to scale formation and breakage during long-term operation. If the water heater breaks, the water does not heat up, and the appliances do not wash the dishes well, because most of the dirt cannot be washed off with cold water. In this case, it is necessary to replace the heating element. The work of the master will cost from 1800 rubles and more, the cost of the part depends on the model of the dishwasher.
Circulation pump malfunction
Why is the dishwasher not washing dishes well? Water may not enter the tank. This happens when the pump that circulates water fails. The washing process in this case does not start at all, or the program suddenly stops at some stage of the cycle. Necessary repair - replacement of the circulation pump. The cost of the master's work will be approximately 2 thousand rubles or more.
Sprinkler impeller failure
The impeller rotates the water sprinkler. When broken, the spray arms stop rotating, which is why the dishes are poorly washed. Only one sprinkler or several can fail. In this case, the part must be replaced. The cost of work - from a thousand rubles or more (plus the purchase of a new impeller orseveral). Do not try to save money and change the part yourself. Firstly, it may turn out that the problem is completely different. Secondly, without experience, it is unlikely that you will be able to correctly install the impeller or other spare part. A qualified master will diagnose and replace the necessary part quickly and efficiently.
Dishwasher thermostat failure
The temperature sensor measures the temperature and sends the received information to the control unit. The software module then gives a command to heat the heating element. If the data from the temperature sensor is not read, the water stops heating to the required temperature, and the dishes are poorly washed. The temperature sensor needs to be replaced to fix the problem.
Faulty water turbidity sensor in the dishwasher
This problem can only occur in expensive models of kitchen appliances. Most dishwashers are simply not equipped with such a sensor. The turbidity sensor sends information about the current state of the water to the software module. If the water is still dirty, the dishwasher continues the wash cycle. When the sensor breaks, the software no longer receives information about the current soiling of the dishes, so it cannot complete the cycle correctly. Replacing a part will cost about two thousand rubles or more (only the work of the master, excluding the cost of materials and components).
Fault or malfunction of the software module
WhyIs the Electrolux dishwasher not washing dishes well? Most of these problems affect any brand of kitchen appliances, but some models have “weak points” that users pay attention to. For the Electrolux car, for example, this is spontaneous freezing at some stage of washing, breakdown of the control unit, pressure switch and intake valve.
The software sends appropriate commands to technical nodes. If the part fails, then the dishwasher completely stops working or does not function correctly. Required repair - “flashing” the module or replacing the control unit completely. You cannot cope with this problem on your own, so you will have to call the master. Estimated cost of work - from 2500 rubles. Additionally (if necessary), you need to purchase a new software module. The cost of the part depends on the dishwasher model.
