What to do if the dishwasher doesn’t wash the dishes badly: expert advice

There are hardly many people who like to wash the dishes. Many housewives have long felt first hand how important it is to have a dishwasher in the house. This wonderful helper is capable of doing wonderful things: to save you from standing for hours at a sink and to please you with clean, dishwashed dishes. High-quality models of dishwashers can work flawlessly for many years. But sometimes, after a while, the housewives begin to notice that the dishwasher doesn’t clean the dishes badly, there are visible stains, grease stains, plaque or even food debris.

Why does a similar incident happen? What to do? How to help your beloved assistant, eliminate the malfunction and improve the quality of washing?

The reasons for the poor performance of the dishwasher

Of course, the quality of washing dishes and cups in the dishwasher depends on many factors. But all of them can be divided into four main groups:

• improper operation;
• clogged or scaled;
• application of poor-quality detergents or errors in dosage;
• dishwasher malfunction.

Let's take a closer look at these causes and think about how to eliminate their consequences.

Read the instruction manual

If your dishwasher does not do the dishes poorly, then first of all, pay attention to how you operate the unit. Typical errors that housewives allow for use can be such as:

• exceeding the amount of loaded dishes, simply put - it is too much;
• operating mode violation - the program is incorrectly set;
• incorrectly stacked utensils in the crate.

Before putting dirty cups and plates in the basket, it is worthwhile to look at least once in the instructions on how to do it correctly. Especially it concerns models of brands Electrolux or Bosch. The arrangement of the dishes should be such that it does not interfere with the rotation of the sprayer and does not block access to where the detergent is located. You also need to ensure that the utensils located below do not block access of water to those items that are at the top.

Now the next step. As you understand, the more dishes loaded in the dishwasher, the less water and powder per unit volume. If you load the car too tightly, water and powder simply have nowhere to turn around - you have to wash it all over again.

The next error is the selection of an operation mode that does not match the type of contamination. If you put a fat griddle in the dishwasher and turn on the mode for glasses - the griddle will remain dirty, because you need to wash it differently. In the “quick wash” mode of operation, which assumes a water temperature of about 45˚, you simply cannot wash the fat off the pots and plates. All options and types of downloads, as well as modes of operation, suitable for them are also described in detail in the instructions.

Breakage and blockages in the dishwasher

If the stains on the dishes after the dishwasher have become a constant phenomenon, then most likely you need to clean it. Yes, yes, like any other household appliances, the dishwasher can become dirty and work worse. In any washing unit, regardless of type and model, there are several places where you should drop in regularly:

• strainer for leftover food;
• bulk filter;
• sprinklers;
• TEN and tank.

First of all, use the operating instructions and find a filter in your dishwasher to trap food particles. If the dishwasher becomes poorly washed, it is likely to be contaminated. Usually the filter is located at the bottom of the unit and is a small mesh. It must be cleaned and washed at least once every 10 days.

If in your apartment not too clean and soft water is flowing from pipes, then you must regularly change the core of the coarse filter, which is located at the entrance to the dishwasher. If this filter is clogged, the water pressure entering the unit will significantly weaken. Low water pressure is another reason why the machine doesn’t wash the dishes badly and stays on it.

Nozzles, heating elements and the tank of your assistant may suffer from the presence of limescale, in other words - scum. To prevent this, purchase a special descaler for your dishwasher. At least once a month, run it in “idle” mode. Use an agent that dissolves and scum.

Important:

To keep the insides of the dishwasher from rusting and not becoming an additional source of problems, after completing the work, wipe the inside with a soft, dry cloth.

Using low-quality detergents

If you notice that the dishwasher does not do the dishes poorly, take a look - the reason may be hidden in the use of low-quality powder or other detergent. If you recently changed the detergent and began to notice plaque and stains on mugs and plates - do not hesitate, this is the reason. To fix the trouble is easy - buy the right product and your dishwasher will wash better.

If you use the same tool as before, and the car began to wash the plates worse, then perhaps the matter is different:

• seems to have a gray patina on clean dishes and there are divorces in the water - there is clearly not enough rinsing agent, you need to adjust itconsumption;
• machine poorly launders traces of tea, coffee and lipstick - the detergent contains little bleach;to improve the result, purchase the appropriate additives or change the detergent;
• on the pans for some reason there are white drips - the lid for salt is not tightly closed;salt powder gets inside the car and it turns white;
• plastic utensils remain greasy - not enough fat-soluble substance;change the detergent or add the additives manually.

Important:

The reason for a dishwasher malfunction can be the use of a tool intended for other purposes. It may seem to you that everything remains the same, but over time, the performance of the unit will begin to deteriorate, and soon it will completely stop washing the dishes.

If your dishwasher began to leave greasy deposits and stains on the plates, remember when you last applied a special salt. The reason may lie in the fact that due to excessively hard water, the ion exchanger failed and the detergent substances began to dissolve poorly in the liquid. Renew salt and dishwasher work will improve over time.

Apparent damage to the dishwasher

If the elimination of all the above reasons did not bring the desired result, the problem can be really serious. Probably the cause of the poor performance of the dishwasher was any malfunction.( See also: How to repair the dishwasher with your own hands?)With long-term operation of such a “coked” heater, it simply burns through. If this happens, the water in the dishwasher just does not heat up, and it is not possible to wash the grease and dirt with cold water.

The impeller of the sprinkler does not work.

Each machine has a special mechanism that spins water in different directions while rotating. This is done to ensure that streams of water could get into the most inaccessible places. If this mechanism does not work, water does not reach everywhere and the dishes remain unwashed.

The sensor of turbidity of water

is broken. Such a device is basically only in new models of dishwashers. The sensor sends water quality data to the control module: if it is muddy, the washing should be continued, if it is clean, the process is completed. When the device is faulty, the “brain” of the machine remains without information and the dishwasher does not understand how to complete the cycle correctly.

The recirculation pump

is broken. This device is responsible for the water supply. If it fails, the unit will not work at all, since no water enters it.

Thermal Relay Burned( Temperature Sensor)

This node in the dishwasher measures the temperature of the water and supplies data to the software control module. Depending on the data obtained, the "brain" gives the command to the heating elements to heat the water. If there is no signal, the water will remain cold and the dishes will be dirty.

Error in the control module

This is the most serious failure. Simply put, your home assistant is blind and deaf at the same time. This part of the unit controls all the processes: it gives commands about water intake and discharge, supply of detergent, degree of spraying and so on. If the control module is knocked down or broken, the dishwasher will necessarily work poorly or stop altogether.

All these faults are very serious. To eliminate them, you will most likely have to invite the wizard or contact the repair shop.
