How to fix error E09 in a Bosch dishwasher

Siemens brand equipment is known for its functionality and the introduction of the latest technologies. Therefore, if there is a problem, the electronics launches a self-diagnosis system. An error code appears on the display, which indicates the cause of the failure. But even if there is no code, malfunctions of the Siemens dishwasher are manifested by external signs. Why equipment breaks down and how to fix it yourself, read the publication.

Typical breakdowns and error codes of a Siemens dishwasher

The design and principle of operation of the Siemens PMM is practically no different from other models. But some problems are especially typical for this brand. If an error code appears on the display, look at the instructions. The manufacturer indicates the meaning of the icons. And if you want to find out the details of solving the problem, the article “Fault codes for Siemens dishwashers” will help.

Here are the most common ones:

• E1 - water does not enter the tank.
• E7 - drying does not work.
• E9/E10 - the machine operates without heating.
• E15 - the Aquastop leakage protection has activated.
• E21/E23/E24 - water does not leave the tank, problems with the drain pump.
• E27 - incorrect network voltage.

How can you determine what is broken in the dishwasher if the code does not light up on the display? To do this, pay attention to the external manifestations of the breakdown. What users most often contact the service center with:

• The machine draws water slowly, the program freezes in the middle of the cycle . The reason may be a clogged filler path or a malfunction of the solenoid valve.
• PMM does not wash dishes well . The main problem is blockage. It is also possible that the circulation pump may break down or due to operating errors.
• The drain doesn't work . The problem is a clogged filter and a blocked pump impeller. Pump failure requires replacement.
• The program is not selected, the equipment is turned off . Problem with the electronic module.

Some problems can be solved at home. Follow our instructions below.

How to repair a dishwasher

We will provide detailed instructions on how to start and repair the dishwasher. Let's start with the most common malfunction.

No water supply

The quality of tap water leaves much to be desired. Foreign-made dishwashers are not designed for such impurities in the water, so the filter mesh in front of the valve quickly becomes clogged. To reduce the number of blockages, install a flow filter in front of the mesh. Clean both elements periodically, then water will flow into the machine normally.

How to clean the system:

No water drain

If there are problems with the drainage system, the water will not drain after washing, and an overflow may occur. Clogging also causes the program to stop. For example, you start the car, water fills, but the wash does not start.

How to disassemble and clean the system:

To avoid blockages, remove food debris from dishes before washing. Also use special cleaning products.

The cause of the breakdown may be not only a blockage, but also a breakdown of the pump. How to check it:

Poor dishwashing

Over time, when using a Siemens machine, the quality of washing decreases. You do the usual load, pour in the detergent, but the dishes that come out aren’t very clean. Why does this happen:

Don’t forget to take care of your equipment, then breakdowns will happen less often.

Dishwasher turns off

If the indicators on the panel flash randomly, an emergency shutdown occurs, the reason is in the control module. Diagnosing a module failure, much less repairing it, is something only a master can do. The design of the Siemens dishwasher makes this task more difficult.

The manufacturer enclosed the control board in a soldered unit. Most specialists refuse to repair it.

The module is one of the most expensive parts of a dishwasher. Therefore, if the machine is old, it is more profitable to buy new equipment than to change the module.

Carry out independent repairs of equipment only after the end of the warranty period. Use cleaning products and clean filters in a timely manner. Then you won’t have to deal with malfunctions and repair breakdowns at home.

Siemens dishwasher errors

Siemens dishwashers are very popular among users because they are characterized by excellent functionality, high detail and interesting design, and thanks to the huge range and wide price range, the devices are available to every average buyer.

Despite decent build quality, users sometimes encounter functional failures, which are displayed on the displays in the form of incomprehensible ciphers and codes. It is possible to fix problems yourself if you familiarize yourself with the encoding values.

What to do in case of serious damage

Significant defects are considered:

• power supply burnout;
• failure of transistors and fuses;
• malfunctions in the permanent memory unit.

Only an experienced technician can diagnose and replace the above parts. If the device is under warranty service, you need to contact the manufacturer's or seller's service center. Repair of Siemens dishwashers at home can only be carried out after the warranty period has expired.

• Built-in Siemens dishwashers 45 centimeters wide
• Dishwasher Electrolux ESF2400OK with compact body
• 3-in-1 stove with dishwasher and oven to save space in the kitchen
• Functional dishwashers Candy

Error codes for machines with a display and their elimination

Almost every Siemens dishwasher is equipped with a self-diagnosis function, thanks to which the device immediately stops working if a malfunction occurs and signals this using a special code. To decipher and further eliminate a problem or malfunction, it is enough to understand the meaning of a particular error code.

To check how serious the breakdown is, or whether it is just a failure in the system, it is enough to reboot the household appliance, which consists of several steps:

• disconnect the equipment from the power supply;
• wait 20-30 minutes;
• connect the device to the power supply.

If after rebooting the code disappears, then you can continue to use the dishwasher as usual. If the error appears on the display again, you need to correctly decipher the code and try to fix the problem yourself.

So, below are the most common error codes that users of Siemens dishwashers encounter.

• E09 is a signal about a breakdown of the heating element (heater). This is typical for devices with flow-through heating elements. Part elements may fail as a result of a short circuit or burnout. To eliminate the breakdown, you need to replace the burnt out contacts or replace the heating element.
• E15 means that the Aquastop protection option has been activated , warning of leaks in the device. It is possible that water has been detected in the pan (200 ml is enough to accumulate). You need to find the leak and discharge the water manually or using improvised means. This may be the tank, the connection point of the drain or inlet hose, as well as the sealing rubber of the hopper door.
• E19 indicates a problem with the detergent compartment.
• E22 - this means that there are no contacts between the pump and the device module. It is necessary to diagnose the electronic control of the equipment, as well as check the serviceability of the pump itself.
• E24 means problems with drainage. There may be problems with the sewer system, the drain hose is clogged and needs cleaning, or there is a kink somewhere. There are special products for cleaning the hose and filters.
• E25 indicates an incorrect water draining process. The reason for this may be a simple clog in the filter or drain hose, or perhaps the drain pump is blocked, or the siphon is blocked. After a thorough cleaning, everything will be restored.
• E27 signals insufficient voltage in the electrical network. This sometimes happens in the evening when the network is overloaded. The optimal solution and prevention of this would be to install a voltage stabilizer.

Along with error codes on the display, users sometimes encounter the fact that during operation the indicator where the faucet is drawn turns on and lights up. This indicates insufficient water supply. There may be several reasons: the filter mesh is clogged, or the water supply solenoid valve has failed. To fix the problem, you need to clean the filters with a brush and also rinse the hose.

It also happens that the display flashes, but the unit does not start working. The reason for this may be improper closing of the door or a loose fit. In this case, the door lock may malfunction or the door sensor may fail.

If any problems or failures occur, there is an excellent help - instructions, as well as contacting the service center.

Why does error e09 appear?

In 10% of cases, error E09 in a dishwasher may indicate:

• about software failure;
• about faulty electrical wiring, poor contact in the socket;
• about the discrepancy between the cross-section of the electrical cable and the power consumption of the equipment;
• about a temperature sensor that has become unusable;
• about errors in the operation of the main module.

In 90% of cases, this is a breakdown of the heating element, as a result of which it is necessary to repair or replace this heating element.

The following provoking factors lead to breakdown of the heating element:

• period of operation of the machine: the older it is, the greater the likelihood of a malfunction;
• scale on the heater, as a result of which it takes longer to heat the water, constantly overheats and, ultimately, burns out;
• filter clogged: as a result, poor water circulation and overheating of the heating element, as a result, it fails;
• worn-out pipes, hoses, seals lead to depressurization and water entering the contacts - a short circuit, the heating element burns out.

Errors of machines without a screen

Users of Siemens dishwasher modules that are not equipped with an LED display also sometimes encounter various types of malfunctions and functional failures. It is possible to determine the type of breakdown and eliminate the causes only if the problem is correctly identified.

Here are the most common mistakes.

• The “Tap” LED lights up, which notifies you of poor water supply or a complete cessation of its supply. The reasons may be different: they forgot to open the water supply tap, the water hose is clogged, low pressure, the water level sensor has failed. In addition, if the hopper door is not closed tightly, the program will not start at all.
• The “Crane” indicator is flashing. This indicates a technical malfunction of the unit. To determine the problem, service testing will be required.
• The LED for the presence of special salt flickers, which indicates excessive scale or deposits on the heating element. A heating element with scale can negatively affect the functionality of the unit.

In addition, after a long period of operation, users sometimes observe intense flashing of all indicators at the same time, which is a sign of an improperly closed bin door. It is recommended to reset all configured settings and restart the machine.

If nothing has changed, then the reason may be a malfunction of the door lock, loss of interaction between the door sensor and the control system, which requires specialist intervention.

Malfunctions and self-repairs

The most common problems with a Siemens dishwasher are the lack of water supply or drainage, poor washing quality and malfunctions of the electronic control unit. Minor faults can be fixed with your own hands. This will require a minimum of skills and tools.

No water supply

If the machine does not draw water or does so too slowly, you need to check that it is correctly connected to the water supply and that the supply tap is not closed. Another reason for the lack of a kit could be a clogged filter. German dishwashers are not designed to work with low-quality tap water. Over time, the filter mesh becomes overgrown with scale or rust. Cleaning is carried out as follows:

• the water supply tap is turned off;
• the inlet hose is disconnected;
• the filter mesh is removed and washed with a stream of water (if there are persistent contaminants, the part is soaked in a solution of citric acid mixed with water in a ratio of 1:20);
• the mesh is returned to its place, after which a flow filter is installed to capture contaminants;
• The inlet hose is connected to the machine body.

To ensure your dishwasher works well, both filters need to be cleaned every 3-6 months.

No water drain

If the device does not drain the water, the liquid remains in the chamber and causes it to stop working. The problem most often lies in a clogged drain filter. Such a malfunction can cause the machine to fill with water and the washing does not start. Troubleshooting includes the following steps:

• disconnecting the device from the power supply and turning off the water supply tap;
• removing trays and baskets from the chamber;
• unscrewing the drain filter located at the bottom of the housing;
• clearing the part from blockages by washing;
• inspection of the pump (to remove the part, press the cover until it clicks and pull the pump towards you);
• installing the pump and filter, connecting the drain hose.

The dishwasher may not drain water due to a broken pump. To check the functionality of this part, remove the bottom panel of the machine and unscrew the screws. The device is turned on its side and the voltage in the pump contacts is measured. The ohmmeter probes are applied to problem areas. If the number 1000-1500 is displayed on the screen, the pump is functioning normally. Cleaning the dishes from food residues and using high-quality detergents helps to avoid reoccurrence of the malfunction.

Poor wash quality

When using the machine for a long time, the quality of dishwashing deteriorates. The following reasons contribute to this:

• use of low-quality detergents;
• weak pressure in the water pipe;
• The detergent supply valve is clogged.

The following steps can help resolve this issue:

• restoration of normal water supply;
• cleaning the filter from dirt;
• regular cleaning of the compartment for cleaning products (the powder clumps, forming build-ups on the valve);
• checking the patency of the injectors (the part is unscrewed and removed from the body, the holes of the blades are cleaned with a toothpick).

The machine turns off

If the PMM randomly switches programs and emergency shutdowns occur frequently, the cause should be sought in a malfunction of the control unit.

It is impossible to test and repair this part of the device yourself.

The special design of the Siemens dishwasher complicates the task. The control board is included in the soldered module. Most specialists do not undertake repairs to the control unit. If the machine has been in use for a long time, you should consider purchasing a new device.

When is professional repair necessary?

If all attempts to independently diagnose a malfunction of a Siemens dishwasher are in vain, you will need the help of a specialist. Contacting a service center or technician is necessary when:

• error code E01 appears on the screen, indicating a breakdown of the electronic control unit;
• code E2 or E02 is displayed, which indicates serious problems with water heating;
• Code E6 appears, which indicates a breakdown of the aquasensor that monitors water quality and hardness.

Sometimes serious damage may be indicated by intense flashing of all indicators at the same time or by the detergent replenishment lamp. You should not carry out repairs on items such as the drain pump, electronic board and motor yourself.

Basic error codes and ways to solve them

Modern dishwashers are highly functional, including self-diagnosis. It prevents many serious breakdowns. Based on the error codes, you can track the status of the device. Each code has its own meaning and description. Different manufacturers have their own indicators.

There are several general categories. Errors are classified according to them:

• electrical failures;
• problems with water heating;
• malfunction of sensors and switches;
• problems with filling/draining water.

Recommendations

In order for the Siemens dishwasher module to serve for a long time and efficiently, it is necessary to use the device for its intended purpose, not to overload it, not to use adapters and extension cords when connecting it to the network, and also to ensure proper care. Here are the basic rules.

• Regular ventilation of the bunker. After each wash cycle, leave the appliance with the door open to dry.
• Control of detergents and auxiliary products. Rinse aid and salt should always be present in the compartments of the dishwasher, as these products prevent the formation of scale and white deposits on the parts of the unit.
• Cleaning all filters. The dishwasher is not a waste disposal unit, so small food residues accumulate, overloading the filtration system. The drainage system must be cleaned every 6 months.
• Periodic washing of the machine. Once a month it is necessary to wash the device using special products.

Proper operation of the dishwashing unit will reduce the likelihood of its failure tenfold.

See below for Siemens dishwasher errors.

Slow water supply and program freezing

According to data provided by service center specialists, Siemens dishwashers break down approximately 2 times less often than most budget and middle-class dishwasher brands. But Siemens still has some weak points. The most common problem is considered to be a malfunction, the main symptom of which is an extremely slow water supply and a periodically freezing dishwashing program, and the choice of program does not matter.

After some time, if the operation of the Siemens dishwasher continues, it will begin to display error E16, first occasionally, then more and more often. Ultimately, the machine will freeze completely, displaying error E16, and restarting will do nothing. What kind of breakdowns give rise to such symptoms? In essence, there is only one reason - the flow filter located in front of the fill valve.

dishwashers are designed for well-purified water with a minimum amount of impurities and suspended matter; their flow filters have a mesh with very small cells, which quickly becomes clogged when connected to a Russian water supply. To make the standard filter less clogged with dirt, you need to install another cleaning flow filter in front of it, and you need to remove both filters and wash them every 6 months.

Important! Experienced craftsmen, in addition to the additional filter, use another protective measure - they immediately change the standard filter. Recently, the manufacturer began to produce spare parts (including filters) specifically for Eastern Europe and Russia. It is precisely these filters that experts recommend installing when installing a machine yourself.

How to restore normal water supply to the dishwasher and prevent systematic freezing of the washing program with your own hands, without the help of a specialist?

1. We reliably shut off the water flowing into the Siemens dishwasher.
2. We pull out the dishwasher so that there is reliable access to the inlet hose and its connection points. But do everything carefully so as not to tear out or crush the hoses and power cord.
3. Disconnect the hose along with the additional filter (if any) from the tee tap.
4. We unscrew the hose on the other side of the dishwasher and unscrew the standard filter from there.
5. Wipe the filter area with a dry, clean, lint-free cloth.
6. Pour lemon juice (100 g per 2 liters of water) into a small basin, pour warm water and soak both filters in this solution for 2-3 hours, then rinse and clean the filters from dirt and install them in place along with the hose.

Dishwasher error codes

Alarm about malfunctions, self-diagnosis of electrical and hardware circuits - error codes for dishwashers. Over the past 6-7 years, manufacturers have been introducing dishwashers into the mass segment. A partial list can be found in the instruction manual. The table from the manual describes the encoding associated with minor and easily fixable problems - you can fix it yourself. The functionality of fixing a dishwasher with your own hands, according to the manufacturer, comes down to three areas:

1. does not turn on - socket, insert the plug into the network
2. does not take in water - water tap, inlet strainer
3. does not drain - there is a foreign object or food debris in the filters, pump, the siphon under the sink or the check valve is clogged.

Point 3 can be easily accomplished only with PMMs from the BOSCH group; the rest do not provide easy access to the pump.

For other dishwasher signals, contact a Good Master. Information on videos and forums is always silent about the subtleties, and that’s the whole point. Error E15 Bosch dishwasher is a classic example.

Common problems and coding are described below.

Review of possible breakdowns

On the display of the dishwasher you can see the error code that has occurred.
Depending on its value, it is determined where the breakdown occurred and what to do in the situation that has arisen. If diagnostics say that an error has occurred, it is important to ensure that it is not a random failure. In order to do this, you need to unplug the machine, wait a few minutes, then turn on the dishwasher again. If upon restart the error is still displayed, this means that you need to repair your Siemens dishwasher.

Errors E1-E6

If the display shows code E1, then the problem is related to the incorrect operation of the heating element. However, this error in Siemens machines can have various causes:

If such a breakdown occurs, you need to check the electrical characteristics of the corresponding components of the Siemens dishwasher. If possible, the used element must be replaced. If there are errors in the functioning of the control board, you must contact a specialist for repairs.

If code E2 appears on the display, this means that the thermistor (sensor that records the water temperature) is faulty. In order to repair a dishwasher, you need to check its serviceability and replace it if such a need arises.

Error code E3 indicates that there is not enough water in the tank. Of course, it’s not difficult to replenish the supply, but the problem is that in this situation the cause was a breakdown of the Siemens dishwasher. There may be one of the following reasons:

When the water switch is faulty, error code E5 can be seen on the display.

In this case, the problem usually occurs due to one of the following reasons:

The node in question is responsible for switching the water sprinklers. It is located under the Siemens heating element.

In the first case, it is enough to inspect the switch and remove the blockage. In the second, the situation is more serious - the engine has probably failed, which most likely needs to be replaced.

Sometimes it happens that there is too much water left in the tank. This is indicated by the E5 code, which will be shown on the display of the Siemens machine. Here are some possible reasons for this:

When a Siemens dishwasher displays this error code, you need to check for dirt. If they are found, it is necessary to clean them. To control the correct operation of the pressure switch, you need to check its electrical characteristics. If a malfunction is detected, this unit will have to be replaced.

The Siemens dishwasher has a special sensor that determines the degree of soiling. It is also called a turbidity sensor. If this is the problem, the display will show error code E6. It can be corrected by replacing the unit.

Errors E7-E18

When code E7 is received, it means the dryer is not working. The cause is a non-functioning fan. In some cases it can be repaired, but sometimes it is better to buy a new one.

In order to start the washing process, it is necessary that the volume of water. Which is in the tank has exceeded a certain minimum level. If this does not happen, error E8 will be issued. One possible reason could be low water pressure in the plumbing system. However, we cannot exclude cases where the heating device or pressure switch of the dishwasher is faulty.

If the flow-through heater does not heat the water (error E9), this may, for example, mean that this unit is burnt out or there are problems with the wires. Which lead to him. In this case, you need to check the contacts and measure the electrical parameters of the heating element. If there are burnt wires, they must be replaced. If the dishwasher unit is faulty, it will need to be replaced.

With E10, the only way to restore the serviceability of the Siemens dishwasher is to contact a service center. In this case, we are talking about the fact that no heating is performed during drying operation.

If error E11 occurs, the Siemens machine starts the work cycle, but the heating element does not work. A malfunctioning thermostat can lead to this result. The problem can also occur when wires burn out or the control module malfunctions.

Sometimes a breakdown results in the heating element being dirty. This is indicated by code E12. The same diagnosis is also possible if a layer of scale forms on this unit. If this happens, to restore the dishwasher's functionality, it is enough to remove the contamination.

An alarm signal is a message that the water temperature in the Siemens dishwasher is too high (E13). This can happen not only due to a malfunction, but also as a result of an incorrect connection of the dishwasher to the hot tap. However, it also happens that the problem arose due to improper functioning of the thermistor.

E14 indicates that the water flow sensor is not working properly. In this case, it will need to be replaced.

If this Siemens model is equipped with the Aquastop leakage protection system, then it is possible that it has tripped (E15). In this case, you have to find the place where the leak occurred and fix it.

When water fills the washing tank spontaneously, this indicates a malfunction of the inlet valve. However, error E16 also has other possible causes:

You can try to remove the foam and see if the Siemens dishwasher starts working. If this is not the case, then you will have to replace the non-functioning unit.

E17 means that faults were detected during filling. This occurs when the flow sensor is faulty or when the incoming water pressure is too high.

Code E18 does not indicate a malfunction. It is intended to inform the user that a drain is taking place and it is not recommended to turn off the machine from the network until it is finished.
