The dishwasher does not drain water and is worth
If after starting it is found that the dishwasher does not make the characteristic sounds of the sink. And opening the door found that there was water in the dishwasher. In such cases, the following often occurs. The dishwasher flies water as usual. But for some reason the circulation pump does not start. The sink does not happen. Water can heat up in the process.
In this case, it is necessary to cancel the program and close the door. If the water merges, but with repeated starting, the same. It is necessary to deal not with the drain of water, but with the cause of which the pump does not start
The dishwasher clogged
Blockage in a dishwasher is not such a rare phenomenon. Non.compliance with operating rules often leads to the fact that the remains of food are clogged by nozzles. Shards of broken dishes can also lead to plum clogging.
But there is a probability of damage and drain pump. Both the dishwasher itself can be salted, and the place where the drain hose is connected. This is usually an ordinary siphon. When connecting the drain of the dishwasher directly into the main pipe.
The probability of blocking the blockage is noticeably reduced.
To eliminate the blockage, it is necessary to clean the drain filter.(mesh under the sprayer) and check the output place to the sewer. If these procedures are unsuccessful. Most likely you can’t do without the help of a master. After all, in some cases. Even to eliminate blockage. Dismantling and partial disassembly of the dishwasher will be required.
The pumping machine pump is faulty

Which is suitable specifically for this model of the dishwasher.
The main feature of a malfunction of the drain pump can be considered the absence of sounds when the drain is launched. Or interruptions with a drain of water, provided that there is no blockage in the dishwasher. It is also impossible to exclude the fact that the pump is launched only when the command is obtained from the control unit. If the food does not come.

Water at the bottom of the dishwasher

In this case, it cannot be said that the dishwasher does not drain water. A small amount of its residues can be taken as normal. But if the water in the dishwasher is above the filter grid.

How to Diagnose Draining and Motor Problems in a Dishwasher
Washing a mesh filter
Let’s start by cleaning the mesh filter, which must be cleaned once a week. After all, on it quickly forms a plaque of fat, which clogs small cells, which is why an unpleasant odor appears, and most importantly-leak.
To remove the filter, the lower basket is carefully removed and disassembled as shown in the photo above. It is enough to rinse the extracted filter under a stream of water with ordinary dishes for washing and installed in place.
Why is it important to clean the filter in time
Before loading into a dishwasher, dishes and devices must be cleaned, ideally, rinse in warm water.
But, since riding the dishes completely from all pollution would mean washing it, the further use of the dishwasher loses all meaning.
Small particles of dirt will remain on the dishes before loading into the dishwasher in any case. But large ones must be removed in advance!
After starting the program, dirt from plates and pots is washed off with water with special detergents to the bottom of the washing chamber. There is a drain cleaning filter, which is often called “garbage”.
Having detained particles of food, fat, napkins and other garbage, as well as detergents, a cleaning filter is very often and quickly polluted.
Given the importance of maintaining the cleanliness of the drain filter, some manufacturers of household appliances already produce dishwashers with self.cleaning filters.

The usual filter is recommended to be cleaned independently every time after completing the next washing cycle!
If you do not have excess free time, clean the filter at least once every 2 weeks. 2 months (if you use the unit rarely).
Pollution and clogs in the filter provoke such malfunctions of the dishwasher:
- The water drains slowly, the washing cycle is extended,
- water does not merge at all, remains in the unit,
- water flows through the door,
- the dishes are not washed out, it remains dirty, in spots and divorces,
- The machine makes noise louder, makes abnormal sounds,
- An unpleasant odor appears, malicious microorganisms multiply in the rampant chamber.
Timely cleaning is saved not only by the filter itself, but all the other parts of the unit! After all, the motor, pump, het and other important components, in the case of improper functioning of the filter, have to work for wear.
So, cleaning the garbage filter and cleaning of clogs in it is a preventive measure that prevents most of the possible breakdowns of dishwashers! This is why it is so important to clean the filter in a timely manner!
Cleaning the garbage filter of a dishwasher
In different dishwashers, a drain.cleaning filter located at the bottom of the washing chamber looks approximately the same.
The filter is not one detail, but a whole filter node. Usually in its design there are several details:
- Fine.masculine internal filter of thin cleaning,
- Inner filter of rough cleaning,
- External filter network,
- Supporting details.
It is not difficult to detect the filter if you get all the baskets for dishes from the car. It is located under the sprayer of water, resembles a glass inserted into the bottom.

It is also not difficult to extract the filter. it without problems is twisted clockwise or simply stretches out of the nest.
Attention! Before you remove the cleaning filter, turn off the equipment from the electricity! If there is worked out water at the bottom of the car, collect it with a rag.
After extracting, the filter is easily disassembled into components and washed under running water.
If the pollution is significant, it is allowed to use chemical and natural detergents:
- laundry soap,
- gel or powder for washing dishes,
- Food soda,
- Salted salt,
- vinegar,
- citric acid solution.
The remaining food and fat are well removed with brushes (including an old toothbrush), toothpicks. You can pre.soak the filter in a cleansing solution for several hours to facilitate the task.
The more often the garbage filter is cleaned, the easier and faster it is.
After the filter is washed, it is installed in the reverse order in the nest.
