Why does the dishwasher constantly drain the water

Permanent drain in the dishwasher may indicate a malfunction associated with the fact that water leaks occurred in the typewriter. As a result of which the drain pump is constantly working. This is done so that in the event of a breakthrough of the pouring hose. Or inlet valve malfunction. Do not flood the room.

As soon as water enters the lower part of the dishwasher. A special and sensor is triggered. The voltage is supplied to the drain pump and the dishwasher constantly drains water.

How to eliminate technical problems

To eliminate these malfunctions, it is necessary to pump out and pour water from the pallet. There should not be water in the Aqua Stop sensor, if there is such a button.

In order for the water to merge safely, professionals advise tilt the dishwasher of 45 degrees and then try to launch it again.

In machines that have a “aqua stop” mechanical, not electric, you have to replace the hose.

This problem can happen if the tank has cracked. In this case, you have to completely disassemble the car. It is better to contact specialists who know this business better.

The dishwasher works, but does not turn off. How to eliminate the problem?

A typical problem in this case is a systemic failure. The voltage difference in the network, a sharp shutdown of power supply can lead to a violation of the main board. If the car freezes in the 1st minute or the error code is shown on the display-restart the technique.

If after rebooting the car is buzzing and does not turn off, the reason is in the pump. The pump can turn on at different points in the cycle. It is important when the control unit gives a signal for pumping water. And for this board you need to get information from the sensors. Therefore, non.stop work can indicate such problems:

How to Clean the Triple Filter and Non-return Valve on Your Dishwasher

  • Problems with electronics or wiring. The software control of the pump was out of order. The wiring was damaged, so the knot does not receive a signal about the shutdown.
  • Incorrect messages from the level sensor. Pressostat gives incorrect indications to the module, as if there is still a lot of water in the tank. Therefore, PMM hung on the plum.
  • Incorrect installation of equipment. Separate models “Electrolux”, “Bosch” and others are sensitive to the slopes of the case. Therefore, they work incorrectly.
  • Incorrect connection of the drain hose leads to a “siphon effect”. This means that dirty water, not having time to go into the sewer, returns back to the bunker. Therefore, the pump operates non.stop.
  • Zasori of the drain tract. The pump “does not calm down” until it fulfills its task. And blockages interfere with the removal of liquid into the sewer.
  • Breakdown of the drain pump, its electric motor.

There are also indirect reasons why the car hung on the plum. This is a leak. Sometimes the system can react by highlighting the E15 error code on the scoreboard, which means the operation of the “Aquastop” defense. If your model has a complete protection, then when water enters the pallet, a float sensor is triggered. Then the pump starts automatically.

There are also breakdowns associated with the control panel, or rather, the control of these. It is manifested so that the sink does not stop. In this case, the buttons on the panel do not respond to clicks. The problem may be in the oxidation of contacts or a breakdown of systems.

Eliminate the blockage, check the connection

You have already understood how important it is to comply with the rules of installation. Most dishwashers are sensitive to distortion. Therefore, the technique should be installed on a flat and solid surface. Adjust the legs if necessary, twist them in height.

Next, check the correct connection to the sewage system. The hose should be located no higher than 50 cm from the floor. Otherwise, water will return to the chamber.

  • Its length should not exceed 2 meters, otherwise the pump will work with a double load.
  • Remove the hose, observing the bend and height.
  • Check the sewer, remove the blockage.

One of our articles describes in detail “What to do if the dishwasher clogged”.

In addition to the hose, an internal blockage could occur. Carry out cleaning.

  • Remove the protective cover.
  • Pour gloves, remove garbage from the impeller. It often happens that an extraneous subject blocks its work. That is why the electric motor freezes, but the liquid does not merge.

If after this Bosch dishwasher does not turn off the program, then proceed to check other components. So, conduct the diagnosis of the pump. You need to inspect the knot to understand the reason for its persistent work. How to get:

  • Disconnect the device from the network.
  • Cross the intake valve.
  • Disconnect communications.
  • Turn the PMM body to the side.
  • Dismantle the bottom by unscrewing the mount.

Disassemble and check the part. If signs of wear are noticeable, install a working drain pump.

Cleaning the level sensor

The main reason why the press starts gives incorrect evidence is the blockage of his tube. The sensor is a round part, inside it there are a membrane and contacts. A tube goes from the relay to the tank. She responds to pressure drops in the chamber, measuring the amount of fluid. If this hose is clogged with garbage, then the signals will be inaccurate.

Pressostat is located in a plastic box near the circulation pump. Disassemble and check the device for serviceability.

The tube is easy to rinse with running water. The work of the dishwasher was not stabilized? It’s time to check the electronics.

Restore the operation of the control panel

Signs of problems are slightly different from the above. When the machine is included in the network, it includes work and freezes. Buttons do not respond to pressing, the modes are not launched. But turning off the technique is not possible. What’s the matter?

To figure it out, you need to understand the essence of the panel. When you affect the keys, they put pressure on a certain area of ​​the controller. Therefore, the car reacts to commands. If the tracks were oxidized on the controller, the simistors burned out, then repair is required.

You can carry out repairs yourself if you know how to work with a soldering iron.

Think three times, because the control board is the detail of the dear. It is better to contact a specialist who will make an accurate diagnosis of breakdown.

For those who decided to start work, we describe the sequence of actions.

Watch the video of the maintenance of the dishwasher:

Our recommendations will help to extend the life of the equipment:

  • Follow the operating rules described in the instructions. Clean the dishes before laying in the bunker.
  • Connect PMM to the network via voltage stabilizer.
  • Carry out the car service at least twice a month.

So you can solve the problems with your “assistant”. If you can’t cope on your own, contact the service center.

Creak in salt container

The Aquastop system can work due to a crack in a special container, which is responsible for storing salt. A crack can form due to mechanical damage during movement or when storing a machine on the balcony or in the garage. In this case, the damage can cause expanded ice.

In this case, the repair can be significantly delayed, t.to. Search for salt for an old machine can occupy several weeks. If the car is less than 3 years old and it is a fairly famous brand, then the tank can be found in a few days.

Diagnostics of the causes and elimination of malfunctions of the dishwasher

To the most common reasons why the dishwasher does not gain water include:

  • not a closed door, as the door lock broke;
  • The filter clogged;
  • The water water system blocked the supply of fluid;
  • The temperature sensor broke or burned out;
  • problems with the control module;
  • Flapsed the filling valve;
  • The water level sensor has broken.

Some of the reasons can be eliminated independently, for example, to clean filters. complex breakdowns require certain knowledge and the availability of special tools.

The door is not closed

A castle is installed in the device door, which protects it from leaks. When it is closed, a signal about the door blocking is received on the control module, the machine begins to work. If the lock is broken, then the door does not close to a characteristic click. The blocking signal does not arrive, the program does not start and the liquid is not gained.

In case of locking of the lock, it can be changed independently. How to do it:

  • The dishwasher is turned off from the mains;
  • unscrew the front panel;
  • Unscrew the broken door lock;
  • install a new latch;
  • Flow the panel.

Filter blockage

The inlet valve filter is installed to protect the equipment from dirt and garbage, which fall from the water supply. It is periodically cleaned or changed. If the liquid is too slowly gained in the dishwasher or does not enter at all, then the reason is most often in the clogged filter. It is cleaned on their own or caused by masters.

Before cleaning, the water supply is blocked. Unscrew the hose, remove the filter. It is located at the inlet in the inlet valve. The net is washed under a stream of water. With severe pollution, it is cleaned with a needle or lowered into a solution of citric acid (30 g per 1 l) per hour. Then the cleaned filter is installed again, the hose is attached.

The water area worked

Dishwashers are equipped with a protective system from leakage. aquastop. The reasons why the technique ceases to work:

If a leak occurred and the liquid hit the pallet, then it will be eliminated. For this:

siemens, dishwasher, constantly, drains
  • disassemble the case of the machine;
  • Tilt the body no more than 35 ° C and drain the liquid;
  • The device is left until completely dry (for 10-12 hours).

In case of failure of the system itself, it is repaired by professional masters. Electromagnetic valves often burn out. Their integrity is checked using a multimeter. If it shows endless resistance, then the valve burned down. Replacement is made in a repair workshop.

The temperature sensor or heating sensor is faulty

With a faulty temperature sensor (thermostat) or Ten, the water begins to gain, but then washing stops. This is because the liquid does not heat up to the temperature set by the program. Diagnosis and replacement of the thermostat in the dishwasher, as well as the replacement of the burned heating, are performed by qualified specialists.

Problems with the control module

The device control module is under the front panel, in the door. He distributes commands to systems, controls compliance with sink modes. In case of malfunction of the module, the technique stops working or works with failures.

To check the integrity of the plateau, the door is disassembled. Visually determine the presence of defects. The faulty module is reflamped or qualified specialists are changed.

Falf valve

After starting the operation of the dishwasher, the control module sends a signal to the pitch valve. It opens and the liquid is filled. If the pump is buzzing, but does not download, then the valve is closed or damaged. The blockage is cleaned themselves or invite a specialist.

The damaged valve is changed, since it cannot be repaired. In addition to damage to the valve, a circuit is possible from the control unit. Diagnostics and replacement is made by the master.

Water sensor malfunction

A faulty water level sensor (Pressostat) submits distorted information about the fluid level to the control unit or does not give signals at all. If the signal is given that the reservoir is complete, although this is not so, then the water will no longer flow. In the absence of signals, it also does not act. In this case, the press is changed.

  • equipment is disconnected from the mains;
  • turn over and remove the pallet;
  • visually determine the presence of defects on the sensor;
  • Check with a multimeter: the lack of voltage indicates a malfunction of the press,;
  • The broken sensor is changed to a new.

Siemens dishwasher constantly drains water

Permanent drain in the dishwasher may indicate a malfunction associated with the fact that water leaks occurred in the typewriter. As a result of which the drain pump is constantly working. This is done so that in the event of a breakthrough of the pouring hose. Or inlet valve malfunction. Do not flood the room.

As soon as water enters the lower part of the dishwasher. A special and sensor is triggered. The voltage is supplied to the drain pump and the dishwasher constantly drains water.

The dishwasher constantly drains but there is no water in the pallet.

In such cases. The cause may be a faulty Aquastop sensor. if earlier the dishwasher proceeded. Water could fall on the sensor. As a result of which he could fail.

Also, a faulty water level sensor can cause a dishwasher constantly draining. To continue the car wash cycle. According to the logic of the program. She needs to drain all the water and pour clean. Controls this moment control module. By means of signal signals of the level sensor.

With a faulty control unit in a dishwasher, a drain pump can constantly work. Often with such malfunctions, water is also simultaneously. The operation of the circulation pump and so on.

If Bosch dishwasher constantly drains water. Most often this indicates that protection against leaks worked. However, such a malfunction in the presence of a display is accompanied by indication E15.

How to find a leak?

One of the very first reasons that the machine drains water immediately when turned on is the Aquastop system. This useful design when the leak is detected automatically blocks the water set and starts the drain to prevent the flood. If you are the owner of the Bosch dishwasher, the self.diagnosis system will notify you of the problem, highlighting the E15 malfunction code. Also, having listened, you will notice that there is no water set.

To eliminate the malfunction, you need to drain the water from a special pallet. It is also necessary to eliminate water from the sensor of the antiperoptext system. To save the parts of the machine from water, tilt the machine body from yourself by 45 degrees. The same operation will help you if the leaks are not found, and the Aquastop system sensor is simply pierced.

On a note! In inexpensive dishwashers, a mechanical sensor is installed instead of an electric sensor, so when the system is triggered against the leak, you need to change the entire hose.

How to eliminate the causes of leaks?

The flood could begin due to a cracked tank or water supply container. This is an infrequent breakdown, and to identify it, the body of the dishwasher is subject to complete analysis. Even if you yourself find a defect, you can’t do without the help of the master. it’s too difficult and dirty work that requires a special tool, skills and spare parts.

Reinstalling the pressure sensor and bulk valve

If the drain constantly works, another reason that caused the failure may be a water fence valve. During the launch of the program, the control module sends a signal to the valve, “allowing” it to start a water fence. The valve opens and the water fence from the water supply starts. If after that the signal of closing does not receive, the water will begin to pour in the PMM constantly, and the machine, having discovered the overflow, will launch excess water drainage.

The process is dangerous, therefore it requires an immediate solution:

  • Crush the shut.off valve, cutting off the machine from the water intake.
  • Expect until the pump stops. If the pump continues to buzz, de.energize the electrical appliance.
  • Remove the machine from the niche, providing access to the water supply hose. it is usually located behind, although there are designs in which the hose is connected from the basement panel.
  • Disconnect the fence hose from the PMM case.
  • Behind the hose you will see a small filter net, which must be gently removed with pliers.

Since we got access to the grid, rinse it under running water.

  • The valve itself is behind the filter.
  • Check the electrician of this part, armed with a tester. Put the probes of the device to the contacts and measure the resistance. The indicators of the working element will be in the range of 500–15000 Ohms. At other values, the part should be replaced.
  • If the electrician is serviceable, mechanical serviceability is checked. To do this, you need to open the hopper door several times during the fence of the liquid into the system. If the bay does not stop at the time of opening the door, the valve is broken.

Replace the part and run the test sink to check the performance of PMM.

If the valve is working, it’s time to check the press. Its task is to control the water level. Когда забирается нужное количество жидкости, модулю посылается сигнал, а тот в свою очередь «командует» клапану перекрыть забор. If the signal from the valve does not go to the board, the problem of the constant bay-skeleton appears.

To verify the need to replace, it is necessary to check the performance of the device. The sensor is usually located in the lower part of the PMM case. Your actions:

  • Disconnect the car from communications and de.energize.
  • Turn the body over to one side or up with trowels, closing the floor in advance with an old bedspread.
  • If the bottom is protected by a lid, dismantle it. Also in some cases you need to remove the back cover.
  • Find the part. its tube goes to a small pressure capacity attached by two bolts.
  • Dismate the tube with pliers, and then remove the tank. check it at the time of the blockage.
  • Checking the sensor is extremely simple. blow into the phone and wait a bit. Clicks are heard? Everything is fine. If quiet, the sensor is subject to replacement.

Checking electricians is carried out by a tester. If the resistance smoothly falls to zero, everything is ok. If the indicators are not normal, the sensor changes new.

We determine the malfunction

The filter is located at the bottom of the dishwasher. His blockage can be seen even with the naked eye. A similar situation concerns the bending of the hose. It is located on the back of the car. It is worth correcting the hose, remove an excess or pushing, drainage of water will instantly appear.

The definition of a clip of the drain system looks a little more complicated. First you need to disconnect the drain hose from the sewer system. Thoroughly inspect it, check the connection with the sewage pipe. To check the hose, you need to disconnect it only from the sewage system, leave the connection to the machine with untouched. If water will pass through it freely through it, it means that the hose has nothing to do with the suction.

Most often, the malfunction is associated with the operation of the drain pump. It is installed at the bottom of the dishwasher. To determine the malfunction and its elimination, you will need to remove the pump. Clean it well. The internal impeller should rotate freely, without jamming and stops. You can check with a regular pencil: just push the impeller.

If all of the above methods did not give a positive result, the dishwasher still does not drain water, then the press.steam room has stopped functioning or the software module has broken down.

The reasons why the dishwasher does not drain water

Before you start talking about repairs, you need to find out why the dishwasher does not drain water. The most common causes of the breakdown associated with the drain are considered:

  • The filter clogged;
  • The drain hose leaned;
  • Garbage got into the drain system;
  • The drain pump broke;
  • Pressostat does not work;
  • The control module broke down.
siemens, dishwasher, constantly, drains

To determine the failed part, you need to know the device of the product, the location of all components.

The reasons why the machine does not drain water

First of all, let’s decide how much water should remain at the bottom of the dishwasher after the end of the washing mode is in a normal situation? The manufacturer does not always indicate in the instructions that the water should remain in the dishwasher, and consumers are in a hurry to dilute panic out of the blue.

Experts argue that in a normal situation, a puddle of about 1 cm deep should remain at the bottom of the dishwasher in order to prevent the drying of sealing gum. In a closed space, the water will slowly evaporate, moisturizing the walls with condensate and the ceiling of the washing tank, and therefore sealing material in a circle. Wet elastic bands will remain elastic for a long time, which means they will not let water pass. If the water in the dishwasher is clearly larger and at the same time the remnants of food float in it, then there is a problem that needs to be solved.

Experts distinguish a number of reasons why the machine does not drain water. These are the reasons.

  • The drain hole is located too high from the floor and as a result of the drain hose is located incorrectly. In this case, the pump cannot pump out the waste water normally, and dirty water, albeit partially, remains at the bottom of the detergent tank.
  • Somewhere in the system there was a blockage. The filter, a pipe or hose can clog, in any case, you will have to understand and eliminate the blockage, otherwise the water will leave badly.
  • The water level sensor has broken, so the dishwasher control unit does not know about the amount of water remaining in the shift tank and, as a result, does not allow the command to pump water.
  • Pump does not work normally. If the pump breaks completely, then the dishwasher will not be able to wash the dishes at all, since the water will not pump out at all. But if the pump then it works, then it does not work, the dishwasher will continue to execute the washing program, but it will not be able to drain the water normally.

In 997, out of 1000 cases of poor drainage of water, the above reasons take place. But in about 3 cases out of 1000 we are talking about a serious breakdown of the control module. If none of the above cases suits you, contact a good master.

Reinstalling the pressure sensor and bulk valve

If the drain constantly works, another reason that caused the failure may be a water fence valve. During the launch of the program, the control module sends a signal to the valve, “allowing” it to start a water fence. The valve opens and the water fence from the water supply starts. If after that the signal of closing does not receive, the water will begin to pour in the PMM constantly, and the machine, having discovered the overflow, will launch excess water drainage.

The process is dangerous, therefore it requires an immediate solution:

  • Crush the shut.off valve, cutting off the machine from the water intake.
  • Expect until the pump stops. If the pump continues to buzz, de.energize the electrical appliance.
  • Remove the machine from the niche, providing access to the water supply hose. it is usually located behind, although there are designs in which the hose is connected from the basement panel.
  • Disconnect the fence hose from the PMM case.
  • Behind the hose you will see a small filter net, which must be gently removed with pliers.

To verify the need to replace, it is necessary to check the performance of the device. The sensor is usually located in the lower part of the PMM case. Your actions:

  • Disconnect the car from communications and de.energize.
  • Turn the body over to one side or up with trowels, closing the floor in advance with an old bedspread.
  • If the bottom is protected by a lid, dismantle it. Also in some cases you need to remove the back cover.

Damage to the electronic module

Remember the item about non.working buttons and the complete lack of reaction of the equipment to your manipulations? If the constant fence is accompanied by such symptoms, the problem is in the board. Most often, the pump is out of order. the pump can work even when there is no water in the system. Elements of the board can be soldered, but only a person with a certain tool and skills can do this. In the most difficult cases, the module needs to be changed, but it is such an expensive operation that it is easier to buy a new PMM.

Now you know all the reasons why the machine is always trying to drain the water into the sewer. Part of the problems can be eliminated without the help of a specialist, the main thing is to understand the device of equipment. Good luck!
