The dishwasher does not drain the water, the owners of such equipment may face such a problem. Often the cause of the trouble is simple, you can cope on your own, with more serious malfunctions you will need to contact the repair shop. It is important to understand the principle of operation of the equipment and to know the main causes of breakdowns.
How the dishwasher works
The process is similar to a washing machine. Initially, water enters the machine, passing by the inlet valve, fills the tank. The water in the dishwasher’s drip tray is below the rubber seal on the door. Here it is heated, it enters the rocker arms using a recirculation pump.
The holes in the beam create a cloud of moisture around the dirty dishes, and some provide rotation of the sprinklers. Then the liquid is drained into a special chamber, where coarse and fine filters are installed and enters the drive. After washing, using a drainage pump, the waste is removed into the sewage system.
All work is provided by separate devices:
- washing progress is ensured by a pressostat;
- fluid heating is produced by electric Tena;
- Using the solenoid valve in the salt compartment, liquid softeners are added to the water. The valve is controlled by a sensor;
- the regulator ensures the completion of the entire dishwashing cycle.
On the door of the machine, there is a device for filling cleaning materials, which are washed out as needed and enter the dishwashing chamber.
Why there is no drained water left in the dishwasher, an expert will be able to answer this question, after finding out the cause of the breakdown.
The list of main reasons
If a filter clogs or a discharge hose breaks, every man in the house can do such work. Worse if the dishwasher does not completely drain the water due to the failure of individual parts or the control system. In this case, the problem can be solved by calling the master from the service center or replacing the unit. Experts name several main causes of breakdowns;
- clogged drainage system and the withdrawal of waste into the sewer;
- the drain pump may have failed;
- breakdown of automation controlling the level of fluid in the machine;
- costly damage, you may need to purchase a new dishwasher - failure of electronic work control.
We will analyze in more detail each type of damage.
Simple Causes of Equipment Failure
Coarse and fine water filters clogged
If, first of all, you need to examine these devices. Such a breakdown leads to the accumulation of dirty water at the bottom of the tank. If you leave a large amount of waste on the dishes, the filter elements are quickly clogged. In this case, you will need to clean it yourself.
If the bosch dishwasher does not drain the water due to this breakdown, the job will be quick and easy. The housing of the filter device is located at the bottom of the equipment, access to it is not difficult. Therefore, it is disconnected and washed under running water. After installing it in place, you need to perform a filter health check.
Having poured several cups of water into the tank, the pump is turned on for pumping liquid from the drive. Water begins to leave - you can rejoice.The machine works, expensive repairs are not required.
Mistress on a note! In order to avoid frequent cleanings of the filtering device of the machine, thoroughly clean the dishes from food debris. Such a simple job will save your man’s time and energy.
But if the water remains in place, you need to perform 2 simple work.
Inspect the drain hose
There is water left in the dishwasher, possibly due to a crease or a clogged hose. You need to look for it on the back of the equipment. If it is pinched or crushed by other kitchen furniture. In this case, it is easy to solve the problem, you need to free and straighten the walls of the hose. Complicate, but a little bit, troubleshooting, clogged hose. In this case, it will need to be cleaned or washed with hot water. If the hose is overgrown with grease, to remove plaque, it will need to be disconnected from the machine and the sewer and cleaned, followed by washing with boiling water.
It remains to check the hose. To do this, they lower it into a bucket and turn on the equipment. Water flows without delay, sufficient pressure - the work is completed.
Important! There are times when connecting the hose to the sewer, and the water stops flowing. This means that you need to check the siphon and the general apartment sewer.
The normal operation of the equipment is affected by such a simple, at first glance, feature - the height of the outlet hose to the sewer siphon. The correct connection of the hose must be carried out, taking into account the basic requirements:
- removal of the dishwasher at a distance no further than 2 m from the point of connection to the sewer;
- the siphon is installed at a height of not more than 500 mm from the level of a clean floor in the room;
- if an air loop is installed from a corrugated hose instead of a siphon, it is installed at a similar distance;
- the hose should not sag to a distance of not more than 50 mm to the floor level;
- Do not twist, break the tube.
If the equipment is installed at a distance of more than 2 m, you will need to make layering from the main pipe.
Water in the dishwasher will not be completely removed if the outlet to the sewer is located above the exit level of the machine. After turning off the pump, residues from the hose drain back into the tank.
Important! If these simple rules are not followed, the equipment can quickly fail.
These were the simplest reasons, then we will analyze more serious ones.

List of more complex reasons
These include breakdowns requiring repair in a service center.
Malfunctions of the drainage system and circulation pump
Drainage can be checked similarly to the outlet hose. If the fluid passes under pressure, the system is working properly. Water does not enter, they begin by cleaning the system. The drainage is working properly - this means that the circulation pump has broken. Let’s take a look at an example - a hansa dishwasher does not drain water.
The pump is first inspected if the holes are clogged and cleaned. The performance of the device is checked by the following simple method. You can check the rotation of the impellers with a simple pencil, pen or plastic tube from the juice. We easily touch a working part, if vibration is felt and the sound of a rattle is heard, the pump works. It is important to carefully touch a working appliance so as not to harm hands or utensils.
Important! Such a check does not give a 100% guarantee of a correct diagnosis, so if the simplest failures were not confirmed, immediately call the wizard. But if, after cleaning the drainage and checking the pump’s operability, there is no water at the bottom of the dishwasher, then you are lucky and the device is in good condition.
The pressure switch is broken
It will be much expensive to repair if the water in the dishwasher does not go away due to a breakdown in the pressure switch. Check the water level sensor in the dishwasher. It is made in the form of a small plastic box.You can check it yourself, but the repair and installation of a new part is better to entrust to specialists.
Dismantle the sensor, blow through the plastic tube and install it in place. Now blow the tube. If a click is heard and the valve closes, the cause of the breakdown is not in this device.
If you have the skills to work as a tester, you can examine with its help the electrical circuit of the Ariston dishwasher or others. If there is a malfunction of the pressure switch, a direct road to the repair shop.
The electronic control system for work has failed
Having examined all the options for how to drain the remaining water from the dishwasher and not having obtained a solution to the problem, in this case you may have to buy a new dishwasher, for example, Samsung and no longer solve the problem with draining the water. Diagnostics is possible only in the service center, and you need to be prepared to wait for the delivery of rare spare parts.
The hardware software module may have failed. Its main purpose is control over all processes, instructions are received from it on the functioning of the entire structure, including the forced discharge of water from the dishwasher. But the price of the module is high, so sometimes it is more profitable to turn in the equipment if the dishwasher is under warranty or if you purchase a new device.
In conclusion, we note
The water in the dishwasher does not drain - this is the reason to turn off the appliance, start searching for a breakdown on your own, or call a service representative. In this case, the dishes will always be clean, and no water will remain at the bottom of the container.
