Bosch dishwasher error codes

Error codes for dishwashers Bosch, Siemens, Neff, Gaggenau

Bosch dishwashers are equipped with self-diagnosis systems. The owner does not encounter them until mysterious letters with numbers appear on the display. What do they point to? Here's a short description, based on which error codes for Bosch dishwashers or another brand your equipment shows:

E1. There is a heating problem. It is highly likely that the heating element or the electronic module responsible for its operation is faulty.
E2. Malfunction of the temperature sensor located in the same block with the heating element.
E3. Water supply problems. The reason must be looked for in a malfunction of the pump, hose or inlet filter.
E4. Flow switch clogged or burned out motor.
E5. Exceeding the level of filling with water in comparison with the permissible level. The problem may arise due to a malfunction of the pressure switch or inlet valve.
E6. Faulty aquasensor - a device that monitors the hardness and degree of water pollution.
E8. Insufficient water level in the sump, self-draining. Often the reason for this phenomenon is insufficiently strong water pressure in the water supply system, and dishwashing equipment cannot be used.
E9. The heating element is faulty. You may need to change it.
E11. Problems with the module and NTC sensor, power wires.
E14. The flow sensor is not receiving control pulses.
E15. Aquastop operation due to water leakage. The specific cause of the leak will be determined by a specialist.
E16. This Bosch dishwasher error indicates an unintended water supply. There may be problems with the level sensor, inlet valve. Sometimes an error is generated due to increased foaming.
E17. Water drainage problems.
E21. The drain pump is defective due to normal wear and tear or foreign objects entering it.
E24. The water does not drain, which can be caused by pinching the hose.
E27. Undervoltage in the network. The problem can be solved by installing a stabilizer.

Knowing the codes of the main problems will allow you to either quickly fix them yourself, or call a specialist in a timely manner. This means that the likelihood of further serviceable work of such valuable household appliances is much higher.

What to do when an error code appears

instructions

Contact VseRemont24 if:

The operating manual for your dishwasher "helper" is lost somewhere.
You have not fully understood the error description.
You took independent actions to eliminate the trouble, but they did not work.
We realized that the dishwasher assistant needs repairs, and you need the help of a professional and experienced master.

Dishwasher malfunctions can be minor and can be eliminated within a couple of minutes, but most of them require complex repairs.

Any external and internal part, as well as the whole unit of the dishwasher, can fail.

Breakdowns of important components lead to the most common malfunctions:

water leak,
lack of a set, drainage of water,
lack of heating / overheating of water,
insufficient amount of water,
inconsistency of the parameters of the electrical network with the necessary,
malfunctions of programs,
failure to perform certain functions or complete failure of the unit to work, and so on.

A defective dishwasher works worse, does not wash dishes well. From a technique that saves water and electricity, it turns into an expensive “pleasure”. Most importantly, using a faulty electrical appliance is unsafe for the health and life of people!

We restore the work of PMM Bosch

Before starting directly to work, exclude a failure in the electronic system at the very beginning. In this case, the technician may mistakenly display this code on the display screen.And to reset such an erroneous "action" of the machine, do the following steps:

Disconnect the equipment itself from the power supply system in order to secure all work - no one has canceled the observance of safety rules.
Let the equipment stand for 15 minutes - this will allow the system to be reconfigured at the next start and return the settings to the previous working parameters.
Connect the system to the power supply - if this code appears on the display again, you will have to carry out a professional analysis of the equipment and clean the blockage.

If the reason is precisely the blockage and not a failure of the electronic settings, at the very beginning, remove the water that accumulates at the bottom of the dishwasher. But at the very beginning, so that you do not get an electric shock, be sure to de-energize it by disconnecting it from the power supply. And then proceed with these steps:

Take out the basket with dirty and unwashed dishes and also remove the lowest trough so that it does not interfere with the cleaning process.
Scoop out the remaining dirty water from the machine and carefully unscrew the filter cover without jerking.
Then pull the filter itself out of the "glass" system.
Inspect it and soak up excess moisture with a rag.
Take a long and preferably thin tweezers, carefully remove the shutter that covers the impeller of the nose.
Inspect and remove the blockage itself and then check the very operation of the impeller.

Upon completion of cleaning, all the parts are put on their workers in the place system in the PMM. And if this does not help, you will accordingly have to clean either the drainage system hose itself or the branch pipe, having reached through the bottom of the machine.

Having freed the PMM from the remnants of dirt and water, remove it carefully by pulling it out to a free, open place and disconnect it from the water supply system and the sewer system.

Then put it on the back wall, open the bottom, remove the panel and disconnect the wires. When the bottom is removed, the filling of the unit opens to the view. After detaching the formwork, clean it. There is a connected hose to the pump - disconnect it too, rinse it completely. For this, it is worth using a special cable with a brush. And after cleaning, return all the parts to their place, connect the unit to the electrical power supply.

In the event of a failure of the drain pump, much will depend on the very nature and type of breakdown. If the impeller breaks down, it is replaced with a new one. But if the winding itself burns out in the system, the pump should be changed completely. Although, as many PMM owners and craftsmen note, if you do not have sufficient experience and knowledge in the repair of equipment, then it is better to call an experienced specialist.

Causes of the error and how to fix them

Before taking corrective action, you should identify the cause of the error. There may be several of them:

breakage of the leakage sensor;
clogged drain;
wear of hoses or their incorrect installation;
breakage of the sprinkler.

The Aquastop may have been triggered by a leak caused by excess foam from the detergent. Therefore, do not add too much cleaning agent. This will not make the dishes cleaner. It is much more important to choose a quality detergent.

First you need to try to solve the problem with simple actions. You will need to move the dishwasher in place a little, shaking it slightly. If the error appeared due to the sticking of the float, then these manipulations will be enough.

After that, drain the excess water by tilting the appliance 45 degrees and leave the machine open for a day to dry. This simple method will not work for owners of a built-in dishwasher.

If the E15 error does not disappear after such a procedure or appears again after some time, you should check for other reasons.

The washing program does not start. The machine does not turn off

In some situations, the dishwasher, after switching on, may not respond to commands and other user actions. At the same time, it is not even possible to turn off the machine by pressing the corresponding button.

All this signals that the control panel is faulty. The most likely thing is that a problem was found with the contacts of the buttons or with one of the control triacs. Do not rush to call the wizard, because in most cases, you can solve the problem yourself.

In order to check and replace the triac, the user will need basic knowledge of the principle of operation of semiconductor circuits, as well as the ability to handle a multimeter and a soldering iron. Those who want to make repair manipulations with the dishwasher with their own hands can do this according to the following list of actions:

Setting up the multimeter. The device is turned on and set to the voltmeter mode, then the minimum value in volts is set. Further, the probes of the multimeter are closed to each other, and the operation of the device is checked.
Removing the control board After disconnecting the power to the dishwasher, open the door. At the ends and on the inside there are fasteners that must be unscrewed. Then the inner part of the door can be removed and expose the desired control board.
Repair of the control board. Having found the desired triacs on the control board, it is necessary to check their serviceability one by one with a multimeter. After finding a faulty component, it will need to be unsoldered and removed. Taking the extracted part as a sample, you should purchase a similar one for subsequent replacement.
Soldering. Carefully, so as not to damage the tracks, it is necessary to solder a new part to replace the old one.

For those who perform such an operation for the first time, you should be guided by the photo above, where the arrow indicates one of the triacs.

Decoding the error code E15

Modern dishwashers can diagnose their systems on their own. If any breakdown occurs, the PMM displays a specific error code on the display. This solution allows specialists to fix defects faster, without wasting time on diagnostics.

This is what the E15 information code looks like on the Bosch dishwasher display

So, if there is an E15 error in the Bosch dishwasher and the tap is on, this means that the Aquastop protective system has been triggered. In this case, the dishwasher stops working. What is this system? She informs that there was a water leak into the PMM sump.

We have drawn a diagram of the operation of the Aquastop system for the readers.

Aquastop is simple and efficient to use. The bottom of the PMM has a slope; a float is located in its lower part. As soon as water enters the pan, the float rises. Rising, it puts pressure on the sensor, which is triggered and transmits information to the control unit (hereinafter also referred to as the ECU) about the malfunction.

The ECU commands the safety valve built into the inlet hose to shut off the water supply (see diagram). At the same time, the drain pump (hereinafter also referred to as the pump) is turned on to pump out liquid from the dishwasher. This protection is so serious that it excludes the possibility of flooding the home.

Burning or blinking of an indicator in the form of a faucet is typical for PMMs that do not have a display

Code meaning

The Bosch dishwasher code system has its own error coding. If the display shows an error under the code e27, then the equipment does not have the required amount of electricity to operate normally. It is worth noting here that Bosch household appliances are very sensitive to voltage drops and require a stable supply of current, which is not always possible. Therefore, at times, error e27 may occur. This means that either too many electrical appliances are turned on, or there is a problem with the power handling system required for operation.

This kind of malfunction occurs, most often, when the plug is included in the tee, from which all other electrical appliances work. In this case, there are two options: turn off all other devices, or put a delayed start. It is convenient and profitable to start the car at night: this way you can get clean dishes by the morning.

If this is your first time encountering this problem, you can try restarting the loop first. First, turn off the machine and disconnect the plug from the mains. Do not rush to immediately turn the plug back on - you have to wait a while. The best option is 10-15 minutes. Then you can try to replay the loop. More often than not, it works. However, it also happens that even after turning it off and on again, the display continued to display an error code indicating insufficient power consumption. In this case, you will either have to disconnect all other appliances from the network, or start the dishwasher in delayed start mode.

Also, the problem may be that there is not enough energy from the substation supplying your home. Such cases are quite rare and a repair team should be called to solve the problems that have arisen. Experienced electricians are advised to connect household appliances to a separate branch of electrical networks, preferably grounded.

However, if you have a problem with overloading the outlet with a standard power of 220 volts, then a voltage stabilizer will help to stabilize the operation of electrical appliances connected to it. It will be discussed in more detail below.

Dishwasher showed error e15, how to fix it?

When the message appears on the display, error e15, it means that something has happened to the aquastop. There is no need to panic right away, you need to check if this function is enabled, perhaps it is simply not activated. So, the dishwasher showed an error e15, how to fix this problem?

The leak sensor may be defective. Protection starts to work and it is quite natural that the machine stops its work. The simplest repair would be to simply replace this sensor with a new one.

This error is the leader among other errors. The reason for this error may be associated not only with the leakage sensor, perhaps water began to flow through the pipes, or a crack has formed in them. Water leakage can also occur due to poor tightening of the pipes.

It is not worth postponing the repair of such an error for a long time. Water will start to collect in the cabinet and this can cause other problems. Usually, they cope with the e15 error on their own, without calling a specialist.

Error diagnostics

First of all, read the technical manual, which lists all possible error codes and the reasons for their occurrence.

Well-known German manufacturers - Bosch, Siemens, Neff - give a decryption of alphanumeric combinations that appear in case of malfunctions.

Inspect the machine carefully to see if there is water leakage to the outside. If the cause was minor malfunctions, for example, clogged litter, you can fix the breakdown yourself.

The most common mistake of users is untimely cleaning of the filter from food debris, napkins and other foreign objects.

Close the inlet valve to keep water out.
Disconnect the drain and water supply hoses.
Tilt the dishwasher forward carefully.
A leak will be indicated by water pouring out of the sump.
If the bottom of the machine is dry, it may be necessary to fix it in the area of the contacts or the control module.
Find the leak. To do this, run the dishwasher in test mode after removing the outer panels.
The dishwasher must be dried within 24 hours after pumping out the water and eliminating the malfunctions.

Causes of breakdowns

Even such reliable equipment as Bosch can fail for quite commonplace, everyday reasons, for example, due to loading excessively dirty dishes into the washing chamber. Food debris washed away by the stream of water will clog the filter and cause clogging.

To avoid this situation, it is better to first clean off the food left on the plates, and only then place them in the machine.

The dishwasher is badly affected by an incorrect connection to the electrical network and a faulty outlet.An overly long drain hose or poor-quality fixing in the area of the water supply can also create problems, so installation and installation should be entrusted to professionals.

If the home craftsman wants to do this on his own, it is necessary to strictly follow the instructions and strictly follow the requirements prescribed by the manufacturer in the passport attached to the unit.

A lot of inconvenience, and as a consequence of problems, is created by incorrect loading of dishes into the washing chamber. Many users do not pay attention to this point and then face various problems.

Before loading plates, cups and cutlery, you must carefully study the instructions and take into account all the wishes put forward by the manufacturer of the equipment.

The dishes, placed correctly, will be perfectly washed and will not require any additional actions from the hostess. At the same time, the machine will not feel overload and will serve excellently throughout the entire operating period.

If your device is more than five years old, then, most likely, some part is simply out of order. Diagnostics and replacement of the damaged part will help to quickly eliminate the malfunction. If you have recently updated your equipment, then the reasons for the breakdown of the dishwasher may be hidden in the following:

Cheap assembly or poor quality parts. As a rule, this occurs on models with a suspiciously low cost. If you are the owner of a Bosch, Indesin, Electrolux or Ariston car, then, most likely, this is not the reason for the breakdown.
The presence of food debris. Only dishes containing very small food particles are allowed to be loaded into the machine. If this is not observed, the filters will become clogged, which will cause possible breakdown.
There is no power. A common reason for non-working equipment is a broken socket.
Poor quality detergents. As a rule, brands such as Bosch, Indesit and Ariston recommend certain detergents that do not harm the machine. If you buy a cheaper option, you will have to spend money on equipment repairs.
Incorrect operation. These include general issues - loose door closing, improper positioning of dishes, loading items that are prohibited from washing in a dishwasher, etc.

These are all reasons, but what do the main breakdowns of dishwashers look like?

What does the code mean

Error E09 in dishwashers of a famous German brand informs about a breakdown of the heating element. He simply burned out. The heating element in dishwashers is somewhat different from the heater of washing machines, since it is built into the circulation pump and cannot be replaced separately. Most often it has to be changed along with the pump; some masters call this dishwasher unit a "warm" engine.

In rare cases, this error may appear due to a failure of the temperature sensor or control board, as well as in case of a violation of the wiring going from the heating element to the module.

Reasons for the appearance

Why did the heater burn out? This question is asked by many users who find themselves in such a situation, and rightly so. You need to know the reasons that led to this malfunction in order to further reduce the risks of its occurrence. Although each part has its own lifespan, and whatever one may say, they wear out. Nevertheless, we list all the reasons:

Water ingress on the heating element. Water can enter the heater through the leaks that appear. Most often, such a place is the sealing gum, which lies between the body of the machine and the filter glass.
Drain filter clogged. Due to blockages, water enters the container slowly, and the heater overheats. Overheating leads to rapid wear.
Hard water and limescale. If there is not enough salt in the ion exchanger, the water remains hard. When such water is heated, scale is formed on the heating element, over time, the plaque leads to prolonged heating of the water and the failure of the heater.

Replacing the heater

Checking and replacing the heating element in a Bosch dishwasher is not too difficult.If you make repairs, carefully approaching this issue, then everything can be done with your own hands. To do this, we need: a Phillips screwdriver, a multimeter and a new heating element. The main difficulty is that the heating element is connected to the circulation block and in order to remove the heating element, you will have to remove this block, which means that you will have to disassemble the dishwasher almost completely. If that doesn't stop you, let's get to work.

At this stage of work, the Bosch dishwasher is connected to the sewerage, water supply and electricity, which means, first of all, we disconnect the machine from the specified communications.
Next, we unscrew the front part of the machine, after removing the plastic clips that are located along the edges of the case. If you are interested in information about attaching the front to the dishwasher, read the publication of the same name.
After that, we unscrew the thin narrow metal panel, which is located immediately under the dishwasher door.
We remove the insulating material and put it aside.
We unscrew the screws holding the pallet.
We open the door of the dishwasher and take out the baskets for dishes.
We remove the lower spray arm and unscrew the glass of the trash filter, in addition, we remove the metal mesh that is located at the bottom of the washing hopper.
We unscrew 4 self-tapping screws that hold the circulation block from the side of the bunker.
We put an absorbent cloth on the floor behind the dishwasher body and place the “home helper” on the back wall.
Disconnect the filler pipe from the circulation block and remove the pallet.

Turning the drain pump clockwise, disconnect it and put it down.
We remove the circulation block from the mounts that are hooked, so be careful.
We disconnect the drain hose from the block and pull the unit out, unhooking the chips with the wires.
We remove the clamp that secures the heating element to the circulation block and disconnect it by removing the chips with the wires. Before removing the chips, take a picture of their location, so that later you will not confuse anything.
We unpack the new heating element and put it in the place of the old one, attaching all the chips to the contacts.

Perhaps the problem was not due to the heating element, so to clear your conscience, measure the resistance of the old part before installing a new one. Fortunately, we prepared the multimeter for work in advance. At the final stage, we just have to assemble the dishwasher in the reverse order and check it in operation. The repair is complete!

So, we figured out how to fix the E09 error on a Bosch dishwasher. We hope our publication will be of practical use to you, good luck!

Press and hold the power button “Power on” for 10-15 seconds. After this action, the vehicle settings are also reset.

Problems with water heating

It is more convenient to consider decoding of Bosch dishwasher fault codes in two versions: in a table or within a classification. We decided that it would be more convenient to divide them into groups according to the nature of the breakdowns, and only then consider the decryptions, as it were, in interrelation. After all, as already mentioned, the system error does not always "come to the user alone." Let's start looking at error codes, and you will understand our idea.

The first group of systemic errors was named by us as “problems with water heating”. This group includes the following codes:

E01 (or F01);
E2 (or F2);
E09 (or F09);
E11 (or F11);
E12 (or F12).

E01 (or F01). The contacts of the heating element are damaged or the integrity of the heating element circuit is broken. If this error pops up on the display, it is highly likely that the heating element has burned out and you will have to change it. In any case, start the test with the heating element. Together with the heating element, the temperature sensor must be checked.

E2 (or F2). This system error can alternate with error E01. In this case, it indicates a malfunction of the water temperature sensor. In this case, the heating element will operate at full capacity all the time, since there will be no information from the temperature sensor. To make sure of the cause of the malfunction, it is necessary to measure the resistance of the temperature sensor contacts with a multimeter (it should be approximately 50 kOhm)

E09 (or F09). This code indicates a problem with the flow heater. E09 pops up on those models of dishwashers where the heating element is located in the bowels of the circulation pump. The error can be corrected by replacing the heating element, but first you need to diagnose the unit with a multimeter and make sure that it is faulty.

E11 (or F11). The code indicates that power is not supplied to the thermal sensor, or the connection between the control module and the thermal sensor is broken. This error also indicates an impressive list of reasons, so you will have to check one by one:

temperature sensor contacts;
the wiring from the temperature sensor for damage;
contacts of the control module.

E12 (or F12). This code is displayed on some models of Bosch dishwashers if too much scale or dirt has accumulated on the heating element. Sometimes after restarting the "dishwasher" instead of the E12 code, the E09 code flies, but in any case, this indicates the same problem.

What kind of breakdown is to blame?

Many modern Bosch dishwashers have an instantaneous water heater inside. The car draws in cold water, and then drives it in a small circle through the heating element until it heats up to the desired temperature. But the question arises: how does the electronic brain of the machine know how much water to draw? The automatic washing machine has a pressure switch that is connected to the control module. The Bosch dishwasher has a similar system, only a water flow sensor is installed instead of a pressure switch, and if it breaks down, the self-diagnosis system displays an E14 error.

This happens in about 65% of cases, so the foremen first of all check this sensor. Secondly, the tightness of the entire system is checked. If there is a small water leak, and the E14 error flashes on the display, then a crack has formed somewhere. In more rare cases, this error is caused by the intake valve or control module.

What will it take to fix it?

You do not need to prepare any accessories and tools in advance. At least until you can pinpoint exactly what caused the E14 error. At this point, we will provide a list of what you may need so that you are mentally prepared for the costs that will have to be incurred and roughly estimate which stores you will go to in order to take everything you need. The final list will depend on the nature of the breakdown, the dishwasher model and the troubleshooting method you choose.

Screwdrivers: flat, Phillips, hex.
Pliers.
New original water flow sensor.
New original intake valve.
Multimeter.
Sealant and electrical tape.

Elimination of breakage

The water flow sensor, like the inlet valve, is located in the dishwasher pan. To get to them, you need to disassemble the machine, so to clear our conscience, we will make a manipulation that can help fix the E14 error. What should be done?

We disconnect the machine from the communications and take it out to the middle of the room.
We put rags under the body so that water, if any, does not flow from the pallet onto the floor.
We tilt the body of the machine first to the right, then to the left, and then back. You need to do this several times.
We put the machine in place, connect it and try to start it.

Why can the E14 error disappear due to these slopes? It's simple, this simple method allows you to equalize the pressure in the system, and if there are no other problems, the machine will work as it should. If the error reappears on the display, you should admit that "the focus failed" and you need to think about how to fix the situation. To check the details of interest to us, you should disassemble the Bosch dishwasher.

We prepare the machine for disassembly by moving it to a convenient place.
Remove the decorative panel of the door, unscrew the front plate located under the door.
We remove the closers from the mounts, which allow the door to open and close smoothly. After that, the door must be kept open.
On the outside of the pallet in the corners there are screws that need to be unscrewed.
We roll out the lower large basket from the dishwasher.
We remove the lower rocker arm, filter, mesh.
We unscrew the screws that were under the mesh.
We throw a few rags at the back of the dishwasher case, and then put the machine on them to get better access to the pallet and the parts in it.
Further, you need to disconnect everything that interferes from the pallet: chips with wires, a water inlet hose, a pump, and so on.

Now you can gently pull the pallet towards you and unhook it from the main body, having full access to all the necessary parts.

The rest is a matter of technology. We measure the resistance of the inlet valve and the water flow sensor with a multimeter and find the weak link. If the parts are in good working order, then we check the wiring, perhaps one of the supply wires is frayed. The inlet valve and water flow sensor can be replaced without the use of tools. We disconnect the chips with wires, unscrew the parts themselves and put new ones in their place, nothing tricky.

It happens that the E14 error is interspersed with the E25 error in the Bosch dishwasher. In this case, you also need to additionally check the drainage pump branch pipe and the pump itself for blockages.

In conclusion, we note that fixing the error E14 on a modern Bosch dishwasher may require the intervention of a qualified specialist. Dismantling an expensive dishwasher is still the lot of professionals, but if you try, you can do everything yourself. Save between $ 40 and $ 110. That is how much the master will take from you for repairs, excluding the cost of parts. Good luck!
