The need to wash dishes every day is sometimes frustrating. That’s why engineers invented the dishwasher. This kitchen appliance saves a lot of time and effort. Modern housewives can no longer imagine their lives without such an invaluable helper. But sometimes the dishwasher starts to wash dishes poorly. Many are lost in such cases. Meanwhile, it is not difficult to identify and fix the problem. Let’s consider the possible causes of malfunctions and ways to fix them.


Possible causes of malfunction


Let’s note at once that there are malfunctions, which can be eliminated only by a specialist. Meanwhile, there are failures that you can fix yourself.


The dishes don’t wash properly


Clean or dirty dishes – a rather subjective concept. For some people, the lack of food remains in the plates is enough. Others demand the shine of sparkling dishes. The dishwasher has implemented a certain average standard. There are many factors that go into meeting that standard. If your new dishwasher is not washing dishes well, try to systematize the complaints and determine the possible cause. They may be the following improper actions.


– Improper operation of the dishwasher.

– Lack of regular maintenance of the dishwasher.

– Failure to use special detergents.


Dish residue remains on the dishes


It is often mistaken for poorly cleaned dishes to have scum on them. Since the dishwasher only runs the program, the following steps can eliminate the cause of plaque formation.


Properly program the machine. Most often, the necessary program is chosen empirically. Theoretically, you should know the hardness of the water used by the machine. Following the enclosed instructions, you must adjust the salt supply for the specific water supply.


Check the availability of salt in the machine. If you run out of salt, it will not be immediately noticeable. Therefore, when you see scaling, you must immediately check the presence of salt in the machine.


Regular maintenance. Sometimes plaque is formed due to contamination of the elements of the machine itself. Therefore, it is necessary to periodically wash the internal parts of the device, preventing the formation of lime deposits on its elements.


Check the presence of salt in the working chamber. Adding salt to the special compartment, you can easily spill a little reagent into the working chamber or not properly close the lid of the compartment. This results in the formation of scale.

Check the quality, availability, and type of detergent. Use only the recommended detergent and the correct amount of detergent.


Why the dishwasher is not washing the dishes properly


There is no immediate answer to this question. First of all, it is necessary to diagnose the mechanisms of the dishwasher. The machine has a special diagnostic program. Running it, in most cases you can determine the cause of the problem. And only then is it necessary to proceed to its elimination.


Correctly identifying malfunctions


If the machine does not react to external influences, that is, it simply does not turn on, then it is necessary to call a master immediately. You should not try to fix the problem yourself, especially if you have no experience in repairing such equipment.


If the machine shows signs of life, it is necessary to start the process of diagnostics. Note that not all models can independently make diagnostics. But if there is such an opportunity, it is necessary to take advantage of it.


As a result of the diagnostic program, a number of letters and numbers will be displayed on the panel. This is an error code. According to it, you need to find the fault indicated by this code in the manual. And then decide how to fix it.


If the error is not detected, the dishwasher is functioning normally, but the dishes are still dirty, the cause can most likely be found and eliminated by yourself.


Solutions to the problem


Once you’ve identified the problem, you can fix it in the following ways.


– Adjust the rinse aid dispenser according to the supplied instructions.

– Use a quality detergent.

– Clean the internal surfaces of the machine from limescale.

– Clean or replace the filters.

– Only place the recommended amount of dirty dishes in the dishwasher.

– Select the correct washing mode.


How to fix the problem yourself


You can start troubleshooting yourself only after the diagnosis has been made and it becomes clear that the malfunction can be eliminated by your own efforts.


The need for regular filter cleaning


Clogged filters sharply deteriorate the quality of dishwashing. Manufacturers recommend cleaning them regularly. The following cleaning intervals are recommended:


  1. The original filters – coarse filters – should be cleaned every six months;
  2. The filter at the bottom of the unit should be cleaned weekly;
  3. The sprinkler should be cleaned when it becomes contaminated;
  4. The heating elements should be inspected semi-annually and if any scale is found, the elements should be cleaned;
  5. The internal surfaces of the housing should be inspected and cleaned annually.


Using the dishwasher correctly


A dishwasher is a complicated appliance. It must be operated strictly according to the manufacturer’s instructions. Before you start the dishwasher for the first time, it is advisable to carefully study all the rules defined by the manufacturer. Firstly, it reduces the risk of premature failure of the machine. Secondly, if used correctly, you can count on free repairs during the warranty period.


There are a number of rules that are common to all dishwashers.


  1. Dirty dishes must be placed correctly in the dishwasher. The layout is indicated in the instructions for use.
  2. The number of dishes placed must correspond to the volume recommended in the instructions.
  3. Dirty dishes should be placed in such a way as to ensure the drainage of water from their surface.
  4. The distance between the placed dishes must correspond to the distance indicated in the instructions.
  5. Before placing the dishes in the unit, clean them of food residues.

Use of special detergents


It is strictly forbidden to use detergents that are not recommended by the manufacturer. The composition of the detergent must provide quality washing of dishes. If the detergent contains a chemical that has a negative effect on the dishwasher, the unit will certainly fail prematurely.


Always follow the detergent dosage recommended by the manufacturer. An excessive amount of detergent will cause a buildup of plaque. Failure to do so will result in poor wash quality.


When to call for professional help


If it is impossible to fix the breakage on your own, you should contact a specialized repair organization with experience in repairing dishwashers of this design. The obligatory call of a specialist is necessary in the following cases.


  1. A heating element malfunction has been detected.
  2. The centrifuge rotation mechanism is malfunctioning.
  3. The water temperature sensor does not work.
  4. The software module does not work.
  5. A malfunction of the water transparency sensor was detected.


It is strictly forbidden to repair the dishwasher yourself if the above-mentioned malfunctions are detected.
