Bosch dishwasher repair: decoding error codes, causes and troubleshooting

Error codes reporting faulty sensors and switches

Automatic control of Bosch dishwashers cannot be implemented without sensors and other electronics. The self-diagnosis system detects such failures. Appropriate messages appear on the display.

E4 indicates that the pressure / flow control sensor in the sprinklers is not functioning correctly.

Possible reasons:

• Mechanical damage,
• blockage,
• Hard water clogging nozzles with hard deposits.

In this case, you need to clean the sprinkler holes or replace the sensor. Usually this is enough.

The appearance of the E6 code indicates a malfunction of the aquasensor. This sensor controls the turbidity of the water. If the dishwasher is loaded with lightly soiled dishes, it excludes the rinsing function. This allows you to reduce the consumption of energy media. To fix this problem, most often the sensor is changed. Sometimes cleaning or replacing its contacts helps.

E14 makes it clear that there is no control for accounting for the amount of water in the tank. Do not try to fix the error yourself. This work is best left to a specialist.

Code E15 means that the Aquastop system has responded. One of the elements is leaking inside the apparatus. It is necessary to inspect the pan, hoses and other elements in this area. The detected leaks are repaired. Flexible connections must be replaced, other parts are repaired until tightness is restored.

User Tips

Note that the above methods for eliminating the E24 code on a Bosch dishwasher sometimes do not help. A forum on such topics made it possible to identify some useful tips to help troubleshoot such a malfunction.

Some claim that the E24 signal is easily eliminated - it is enough to thoroughly clean the drain sleeve.

Some of the users, having dealt with the error for a long time, identified the cause associated with the drain pump. It turns out that when it was activated, the impeller did not rotate, and the pump did not pump liquid.The problem was that the rotor was completely stuck near the sleeve walls and rotated very tightly. To solve this problem, I had to clean the bushing and rotor, lubricate each element.

There are user tips that the E24 error on the Bosch dishwasher is removed by simple steps - you need to turn the unit on and off. But we will not talk about this method in detail, since resetting the error code does not mean eliminating the cause of its occurrence - the dishwasher will operate at maximum power, and in the end this can turn into significant problems.

The E24 code that appeared immediately after turning on the machine can be eliminated by opening the loading door. Consumers even made their own algorithm of actions:

1. the dishwasher turns on;
2. it is necessary to wait at least a minute for the pump to work;
3. we wait for a click, behind which the characteristic sound of water intake is heard;
4. after thirty seconds, you must open the door and then close it again so that the dishwasher completes the cycle.

As the authors of the methodology assure, the dishwasher functions normally, but the constancy of such actions is annoying. Having diagnosed the breakdown of E24 in a similar way, many solved the problematic issue by rearranging the magnets of the door sensor that controls its closure. This probably happens, but recall that the E24 signal is associated with the possibility of draining, and not with closing the door. The complexity of this method of troubleshooting lies in the fact that all actions must be strictly timed.

Having studied all the recommendations of users, we nevertheless identified an effective method to deal with the error code. Its essence lies in the following actions:

• the right panel of the machine body opens, the sealing element is removed;
• behind it is a plastic container with tubes in which a blockage can form;
• each branch pipe should be removed and thoroughly cleaned, while pouring water into the drain sleeve.

What to do if these tips do not help to cope with the problem? There is only one option left - to invite an experienced craftsman from a service center who will check the operation of the control unit. Perhaps, for some reason, he stopped correctly recognizing alarm signals.

Errors 0E, 0F, 0C, E3 on a Samsung washing machine

What happened

The washing machine displays an error message "0E",

"0F"

"0C"

or "E3".

In models without a display, the indicators of all washing modes + the two lower temperature indicators light up.

● Incorrectly connected drain hose to the sewerage system;

● The water inlet valve is blocked in the open position.

What to do next

Disconnect the machine from the socket.2 Disconnect the drain hose from the sewer (siphon, pipe). If you have extended the drain hose, remove the part you have extended.3 Dip the end of the drain hose into a tub or sink.4 Turn on the machine and run the same wash cycle.

Do not wait for an error to appear if the machine has taken a full drum of water. Stop washing by pressing the "Start / Pause" button and submit a repair request.

If the error does not appear, then the drain hose was connected incorrectly. In order for the machine to work without errors, correctly connect the drain hose to the sewer.

The sound of flooding is heard

If you hear the sound of water filling, but the machine still gives an error, then:

• or there is too much laundry in the machine for the selected washing program,

  Information on the maximum load of laundry for each washing program is indicated in the user manual, section "Operation" or "Instructions for washing clothes".

• or things that are loaded into the drum absorb a lot of water: pillows, blankets, etc.

  For washing, a certain amount of water is poured into the machine. If the clothes absorb more water than planned, the water level in the machine will decrease. The sensor will detect this and the machine will show an error.

If there are few things loaded and there are no things that absorb a lot of water, then check the water pressure through the inlet hose. If the pressure is weak, an error will appear. In this case, contact a plumber.

No sound of flooding

If, after starting the wash, you do not hear the sound of water filling, and the machine shows an error, then:

1. Make sure the water supply to the washing machine is open.

2. Make sure the house has cold water. To do this, open the cold water tap. If there is no water or the pressure is weak, contact a plumber. The washing machine will not be able to start washing without water.

3. If the tap is open and there is water in the house, then check the water pressure through the inlet hose.

4. If the pressure is strong:

   A. Remove and clean the inlet strainer.

   B. Make sure the drain hose is connected correctly: it should exit the machine and immediately go down. If the hose is not positioned correctly, the water will drain out of the machine and it will show an error.

   ON THIS TOPIC:

   How to properly connect the drain hose

   C. Unplug the machine for 15 minutes to reset the control box.

   D. Plug in the machine and run the same wash cycle.

   E. If the error does not appear, use the machine further, everything is in order with it. If the error appears again, contact the support service.

   If the pressure is weak:

   Contact a plumber. The washing machine will not be able to start washing with low water pressure.

   If there is no pressure:

   A. Unscrew the other end of the hose from the water pipe and try pouring water into it.

   

   

   

   

   

   

   

   

   B. If water flows through the hose, have a plumber check the water supply faucet and water pipe. If water does not flow through the hose, it is clogged. Buy a new hose or flush it with a strong jet of water.

What to do when an error code appears

When an error code appears, you need to refer to the instructions for the dishwasher to find its decoding and understand what is the reason and what exactly is wrong with the unit.

How to get rid of the smell in the dishwasher

Contact VseRemont24 if:

1. The instruction manual for your dishwasher “assistant” is lost somewhere.
2. You didn't fully understand the description of the error.
3. You have taken independent steps to eliminate the trouble, but they did not work.
4. We realized that the dishwasher needs repair, and you need the help of a professional and experienced craftsman.

Dishwasher malfunctions are minor, fixed within a couple of minutes, but most of them require complex repairs.

Any external and internal part, as well as the entire dishwasher assembly, can fail.

Breakdowns of important components lead to the most frequent malfunctions:

• water leak,
• lack of set, water drain,
• lack of heating / overheating of water,
• insufficient amount of water
• inconsistency of the parameters of the electrical network with the necessary ones,
• program crashes,
• failure to implement individual functions or a complete failure of the unit to work, and so on.

Water heating problems

It is more convenient to consider decoding fault codes for Bosch dishwashers in two versions: in a table or as part of 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 transcripts as if in interconnection. After all, as already mentioned, not always a system error "comes to the user alone." Let's start looking at error codes, and you will understand our idea.

The first group of system 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 likely that the heater has burned out and you will have to change it. In any case, start the test with the heating element. Check the temperature sensor together with the heating element.

E2 (or F2). This system error may appear alternately with error E01. In this case, it indicates a malfunction of the water temperature sensor. In this case, the heating element will work at full power all the time, since no information will be received from the temperature sensor. To verify 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 problems with the flow heater. E09 pops up on those models of dishwashers where the heating element is located in the depths of the circulation pump.You can fix the error 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 temperature sensor, or the connection between the control module and the temperature sensor is broken. This error also points to an impressive list of causes, so you will have to check one by one:

1. temperature sensor contacts;
2. wiring from the temperature sensor for damage;
3. 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 crashes, but in any case, this indicates the same problem.

The most common damage

float sticking

One of the possible reasons for the error code E15 to appear on the display is the sticking of the float located in the pan. If this is indeed the case, fixing the problem is easy. Disconnect the PMM from the mains by removing the mains plug from the socket. Swinging, moving from place to place (it is desirable that the body vibrates at the same time) or tilting the body at an angle of 30-40 ° to one side will help correct the situation. True, such manipulations are not easy to do if the equipment is built into the furniture.

Water has leaked from the dishwasher tray or one of the hoses is not sealed

Be careful, as a strong slope will cause water to leak from the pan to the floor. This method often helps to restore the normal operation of the system. In conclusion, it is necessary to tilt the machine so that the water is completely drained from the pan.

Do not rush to immediately turn on the unit.It is necessary to dry the pallet, which takes about a day. You can carefully use a hair dryer, then PMM will dry very quickly. If the alphanumeric combination E15 disappears when you turn it back on, then the problem has been fixed. Otherwise, you will have to deal with more serious damage.

Too much detergent

Excess detergent can lead to excessive foaming and the appearance of the error code E15, so the detergent must be strictly dosed.

Dishwasher malfunctions: basic troubleshooting algorithm

You have set the dishwashing mode, the indicators light up, the process of supplying and heating water is in progress, but the machine refuses to perform its main function - washing dishes. The causes of this malfunction of dishwashers are as follows:

• Filter clogged. It is located at the bottom of the dish loading chamber. Fixing this problem is simple: remove the filter, rinse it and install it in its original place.
• Clogged nozzles. The dishwasher does not spray water. You can clean the nozzle holes with an ordinary toothpick. A clogged nozzle can also cause low pressure, as a result of which the dishes are not rinsed well. Sometimes, if the rocker does not rotate, the problem may be a malfunction of the circulation pump.
• A breakdown of the circulation pump that supplies water to the nozzles is a fairly serious breakdown, which manifests itself in the fact that the machine stops taking in water. There is only one way out: replace the faulty circulation pump with a working one.

The reason for the failure of dishwashers in this case may be damage to the winding of the electric motor.You can check the integrity of the windings by checking the interturn circuit with a multimeter.

overflowing water

Most likely, the problem you have is a failure of the water level sensor. It is possible to fix the problem by replacing the sensor with a new one. If the machine is turned off and water is supplied to the chamber, then the problem is in the solenoid valve, which prevents the flow of water. Replacing the valve with a working one does not cause any difficulties.

Underheating (overheating) of water

It often happens that the machine heats the water too much or vice versa - it does not heat it up. The cause of overheating is a breakdown of the temperature sensor, which leads to increased vaporization and equipment breakdown.

Reasons for underheating can be as follows:

• Temperature sensor failure.
• Low water pressure - if there is a problem with the nozzles or the pump.
• Malfunction of the heating element - you can check by measuring the resistance with a multimeter).

No water drain

If the water does not drain into the sewer, the cause of the Bosch dishwasher error may be a pump failure or a clogged drain system. Sometimes the dishwasher does not drain the water completely. Most likely, the reason is that the drain hose is too high and after the pump is turned off, part of the water flows back into the chamber.

The body is shocked

With a probability of 99%, we can say that a breakdown of the heating element has occurred. To verify this, you need to open the heating element and carefully examine it. If there is damage, the heating element is replaced with a new one.

No detergent intake

If the dishwasher does not pick up the detergent tablet or powder, then most often the cause of the problem is low water pressure or clogged nozzles. As a result, no water enters the dispenser.

No power

Bosch dishwasher errors are manifested in the fact that the appliance does not turn on, does not react in any way to pressing a button. The causes of the malfunction may be the following:

• The socket has failed.
• The interlock burned out.
• Door not closed.
• The power button is broken.
• Faulty network filter.

extraneous noise

The presence of extraneous noise indicates damage to the bearings of the motor or pump. Most often, bearings fail from wetting with water. Water seeps into the bearings due to seal damage. As a result, the equipment begins to make a lot of noise during operation.

To completely eliminate the malfunctions of dishwashers, you will need to replace not only the bearing, but also the oil seal.

Dish drying not working

Some models of dishwashers are equipped with the function of drying washed dishes. Drying is carried out using a fan installed inside the chamber. If the dryer does not work, while all other functions of the technician perform normally, then the problem is in the fan.

To verify this, you need to check the supply contacts and windings with a multimeter. If necessary, a broken fan is replaced with a working one.

Water leaks to the floor

This is one of the most common dishwasher failures. There can be several reasons for the flow of water under the case:

• Poor condition of door seals. They may need to be replaced or cleaned of plaque.
• Damaged pump seal. The way out is to replace it with a new one.
• The clamps on the water supply and drain hoses are not tightened enough, there are no seals on the pipe connections.
• Water tank damaged. Most often it cannot be repaired, the tank is replaced with a new one.

Electronic tips about the type of breakdown

Modern models are equipped with many sensors that control most of the processes. They are located on the inside of the body, at the valves, behind the walls and are sensitive to the water level and temperature changes.

As soon as an emergency occurs, the sensors give a signal, the relay is activated and stops the washing process. The electronic display shows the error code of the dishwasher, by which you can determine the reason for its stop.

You can not use the codes of one brand to determine the breakdowns of another - different manufacturers have different symbols. They usually have alphanumeric designations.

A list of codes can be found at the end of the manual, in the repair section. Usually it has the form of a table, where the designations themselves are entered, a list of breakdowns and recommendations for their elimination.

Fragment of a table with Bosch SMV44IX model codes. Explanations from the last column help to cope with the problem without resorting to calling specialists

Sometimes self-diagnosis gives a code indicating several reasons at once - you will have to check the probability of all in turn. If the breakdown is serious, then in the table you can find the recommendation “contact a service center” or “call a specialist”.

In older models, especially those that have survived more than one repair, electronics often suffer and failures occur.

If the machine gives out a deliberately incorrect code, you should take it in for repair or think about buying a new one - kitchen appliances, like other appliances, have a limited service life.

Popular breakdowns of dishwashers of well-known brands, error codes and methods for their elimination, we have considered in our following articles:

Emergency actions in case of an error in the dishwasher

All methods of handling the dishwasher are described in detail in the instructions. There is not always time to choose and think long and hard about what actions to take. In such situations it is necessary to abort the program. To do this, turn off the device for 20 minutes or hold down the Start button for 15 seconds. After that, they begin to understand the cause of the problem.

If the breakdown is simple, for example, the water drain hole is clogged and the PMM has not finished the program, then you can fix it yourself. In the first case, the drain is cleaned, in the second, the program is restarted. But there are situations when the reason is completely incomprehensible. Here the help of the master is required.

Installation of the protection system

So, we already know the decoding of the E27 error code. It remains to find out what needs to be done to avoid such a problem.

The difficulty lies in the fact that for the Bosch dishwasher you will have to choose the right stabilizer. Practice has repeatedly proven that it is better to install one device on several household appliances at once - a refrigerator, a washing machine, a dishwasher.

If possible, experts recommend installing a main-type stabilizer to cover the entire electrical network of the apartment. This option will cost much more, but it will reliably protect all devices from unexpected malfunctions.

Main parameter when choosing a stabilizer is considered the power of the device. It is determined taking into account the corresponding values ​​\u200b\u200bof electrical appliances, which are displayed in the accompanying instructions. Having calculated the total value, you should add a twenty percent margin to get the final result.

Based on the electrical network of your home, the stabilizer can be compensatory or wide-range. The first device helps in the fight against a decrease in voltage, restoring it to normal parameters. The dimensions of the device are small, and the cost is within reasonable limits.

A wide-range stabilizing device is recommended for use in cases where the voltage is not only below the normal level, but also increases significantly.

It is believed that voltage surges in the range of 165 - 255 V will "level" the compensating device, protecting your Bosch dishwasher from error E27, in other cases it is better to install a stabilizer with a wide range. But remember that its cost is much higher, and in the process of operation, the device makes characteristic sounds.

A stabilizer is connected, which protects several household appliances at once from voltage surges, quite easily. It should be plugged into a power outlet, and the plugs of the power cords of the Bosch dishwasher and other units should be connected directly to the device. The device does not need to be configured.

The situation is somewhat different with the main protective device. It is connected to the network using terminals, and it would be better if an experienced craftsman does this work.

Electricity experts recommend turning on household appliances through a stabilizing device, additionally installing difavtomatov. This measure will protect the Bosch dishwasher and other appliances from error E27 and save the electrical network from possible overloads. Simply put, as soon as the network is overloaded, the automation will work and interrupt the flow of current.

There is another option - to write a statement to the housing and communal services, so that they figure out for what reasons the voltage drops in the network. We note right away that this measure rarely leads to success, and it will take a lot of time to resolve the issue.

Site preparation

Novice masters begin to install the Electrolux dishwasher with a swoop, neglecting the stage of site preparation. And then they run into problems during installation that could easily have been avoided if the place had been properly prepared. For some reason, some people think that you only need to prepare a place for a built-in dishwasher, but in fact, you should always take care of the place.

First of all, you need to think about how to put your new “home assistant” in such a way that it is placed comfortably and is closer to communications. Keep in mind that the distance to sewer and water pipes should not be more than 3 m, ideally, the smaller this distance, the better. In addition, care must be taken to:

• there was a solid and even base under the dishwasher;
• a connection point to cold water was organized;

• a point of connection to the sewer was organized;
• the dishwasher could be powered from a reliable outlet directly or (preferably) through a voltage stabilizer.

You need to take care of the base when the floor in your kitchen is completely rotten, and the base sags and creaks a lot. If you have a regular floor, then even if there are small bumps and drops, it will work. Next, we turn to the organization of the outlet for the supply of cold water. At this stage, it is enough to make sure that the tee-faucet will fit under the sink between the outlet to the mixer and the pipe with cold water, and the hose from the dishwasher will reach there without any problems. We will describe the process of installing the crane a little later.

Next, check the distance from the siphon to the installation site of the dishwasher. The hose for draining the waste water will be connected to the side outlet of the siphon and it must be long enough. If the hose is too short, it will have to be extended, and this is additional trouble. If you have a siphon installed without a drain, or the outlet is already occupied by a washing machine, you will have to buy a siphon with a free outlet or throw a drain hose right over the edge of the sink, and this is extremely unaesthetic.

After that, check the outlet. The outlet must be reliable and withstand the rated load created by the dishwasher with a large margin. It is better to connect not directly, but through a dishwasher stabilizer. This device is able to prevent damage to the electronic filling of the dishwasher in the event of a power surge.

The built-in dishwasher must clearly fit into the niche. To do this, you need to measure the body of the machine, not forgetting the protruding parts, and then correlate this size with the dimensions of the niche into which it is planned to build the “home assistant”. In this case, it is not necessary to rely on the manufacturer, who described the dimensions of his offspring in the characteristics.

Prepare everything you need

To install an Electrolux dishwasher, you need a small number of tools and accessories. Least of all problems with tools. All you need is a screwdriver, pliers, an adjustable wrench and a building level. With consumables a little more difficult. Will have to purchase:

1. FUM-ku, PVC electrical tape, sealant.
2. Siphon with outlet for connecting a drain hose (fitting).
3. ¾ tee tap made of brass or bronze.
4. Flow filter with a mesh, so that large debris from the water supply does not fall into the dishwasher.
5. A tee for a sewer pipe (if the sewer outlet was not organized in advance).

The list of components expands significantly and becomes more expensive if electrical communications were not properly prepared in advance. In the absence of a normal outlet, you need to buy:

• three-core electrical cable 2.5, copper (the length must be sufficient to reach the shield);
• moisture resistant socket of the European standard;
• 16A difavtomat for line protection;
• voltage stabilizer (optional).

How to fix a dishwasher yourself?

There are two typical problems for Bosch PMM models. They are associated with water. Often users complain about the appearance of the E15 code on the display. This indicates the operation of the Aquastop protection. But it's not always a leak. Follow these steps:

1. Tilt the PMM body back and look into the pan.
2. If there really is water in there, drain it.
3. Return the float switch to the off position.

Sometimes the cause of the operation is the incorrect placement of the inlet hose gasket. It may have moved during installation. Therefore, make the connection following the user manual.

Dishwasher won't turn on

Have you connected the machine to the network, pressed the Power button, but nothing happens? The lights on the panel do not light up, no beeps are heard. What to check:

Network wire. Sometimes it bends if, during the rearrangement, it is pressed against the body of the dishwasher. If you notice damage to the insulation, do not do homemade twists. This approach can lead to a fire. Replace cord immediately.

• Fork. The presence of melting and burns indicates a breakdown. Install the correct item.
• socket. To check its performance, connect another device. Works? So the outlet is correct.

Leave the problems with the electronics and the control unit to the master. Here you need an accurate diagnosis, which is carried out with a multimeter.

Water intake and drainage problems

With such a problem, simple carelessness should be excluded. So, it's worth checking out:

1. Is the stop valve open. Perhaps it was accidentally blocked.
2. Is the inlet hose straight? If it is bent, pinched by a foreign object, water will not flow.

When installing a hose with Aquastop protection, you need to monitor its operation. When the system is triggered, the absorbent is saturated with moisture, which blocks the passage. This is a one-time protection, so you need to completely change the hose.

Maintenance includes cleaning the system of debris:

• Shut off the water supply.
• Disconnect the hose from the housing.
• Take out the mesh filter.

• Rinse it clean.
• Check intake valve operation. Examine its holes. If debris enters, the passage becomes clogged, which makes it difficult for the membrane to move. It does not open, and the liquid does not flow.

With problems with draining, the pump does not necessarily break. Check parts for clogging:

• Open the chamber door.
• Take the baskets out of the bin.
• There is a filter at the bottom.

• Unscrew and clean the part.
• Check pump impeller. Pieces of food passing through the filter can block its rotation.
• Remove water from the hole.
• Remove the cover by pulling it towards you.
• Put on gloves, remove blockage.
