Bosch household appliances are considered the embodiment of functionality, reliability and durability. However, any equipment with intensive use may sooner or later require additional intervention to improve or restore its optimal functioning. Any malfunctions in the operation of the device are recommended to be eliminated immediately. Urgent repair will allow you to quickly return the device to its working capacity.
A professional technician will point out the causes of the failure and help eliminate it. However, some problems are completely solvable with your own hands, since they can be effectively solved at home. Using the instruction manual for a particular Bosch dishwasher model, it is quite possible to independently solve problems when:
It is quite possible to repair the Bosch dishwasher with your own hands if an error is constantly displayed on the equipment display. It is easy to solve the problem of the impossibility of collecting water. Another common malfunction is the inability to open or close the appliance door.
For any type of breakdown, it is important to carry out the most accurate diagnosis. Often the participation of the master is optional here. Using the instructions for use of the dishwasher, you can carry out this procedure yourself. For example, if the equipment cannot be turned on, the Bosch dishwasher repair manual suggests first checking the voltage level in the network.
The Bosch manufacturer's troubleshooting guide for other instrument malfunctions suggests:
Sometimes repairing a Bosch dishwasher at home on your own is impossible without partial disassembly of the equipment. For example, the SRV55TO3EU model implies a mandatory check of the functioning of internal components, including valve sensors and pumps.
Don't make your life difficult. An urgent self-repair of a Bosch dishwasher will be more productive if we take into account the indicators of self-diagnosis of malfunctions. This system is built-in, and all devices of this popular manufacturer are equipped with it. When a certain malfunction is detected, the display will show a message denoting one or another error code. Using the instructions for the device, it is easy to identify the problem. After identifying a malfunction in the operation of the device, you can proceed to its elimination.
Correct repair of the Bosch dishwasher by video is recommended to be performed on your own if the breakdown is simple:
This approach does not require specific knowledge or skills. Bosch high-performance dishwashers of all models, including the popular SRV55TO3EU version, are easy to clean. On them, the drain system is often clogged. In case of this malfunction, you need to inspect the drain hose, as there may be kinks on it. It is also worth checking the filter, which may be clogged with food debris, check the siphon installed under the sink for clogging.
A productive repair of a Bosch dishwasher with your own hands using video can be carried out even when troubleshooting problems of average complexity. Malfunctions include the sinking of the power button and the breakage of the door, which is difficult to open. In this situation, you will have to use the prompts and remove the front or side panels.
If the device is used intensively, the door lock that fixes it often fails. To replace it, it is necessary to disassemble the front panel of the device. Sometimes the breakdown lies in the jamming of the power button. In this situation, you will need to remove dirt from the groove where the button is installed. If the problem persists, the button should be replaced.

It is quite possible to restore the functioning of the equipment produced by this well-known brand without the participation of specialists. The main thing is to take into account the features of the device and strictly follow the recommendations of the operating manual.
If you bought a dishwasher, and it suddenly decided to break down, do not get upset and call the service center - you can do the repair yourself, without outside help. Dishwashers are not so complicated as it seems at first glance. Do-it-yourself Bosch dishwashers are repaired by many people. The main thing is to learn how to understand basic faults, which we will talk about in this review-instructions.
Repair of Bosch dishwashers is carried out in the same way as repair of any other dishwashers - they are arranged in about the same way. And the simplicity of the design allows you to count on success when carrying out repair procedures. Let's see why the dishwasher may not turn on and show absolutely no signs of life.
First of all, you should suspect a mechanical on / off button. It is not designed for a million cycles, so it can easily fail. Contact groups are weak here, therefore, breakdowns occur frequently. The repair is preceded by testing the button - you can measure the presence of voltage at the output or test the functionality of the contact group with a multimeter operating in ohmmeter mode.
We can also suspect other components of the Bosch dishwasher as a malfunction - this is the power cable and the control module. We check the integrity of the cable with the same ohmmeter, but it is difficult to test the control module at home. But if food still comes to him, then we have no choice but to sin on him.
Bosch dishwasher malfunctions can be very different - after all, there are a huge number of parts on board that can break. If the dishwasher has stopped starting the programs, then the repair is preceded by a thorough check of the technique. First you need to open and close the loading door - it is quite possible that the cycle does not start precisely because of it. At the next stage, we check the filter of the device.
The lack of start can be caused by other malfunctions. If the dishwasher is modern, it will show an error code ... Looking at the table with the codes, you will understand what exactly is out of order. Such a diagnostic scheme is particularly convenient, since it allows you to quickly calculate a faulty node. You will only have to carry out repairs, focusing on the data obtained during the diagnosis.
We are trying to calculate the malfunctions of Bosch dishwashers in the absence of normal water filling. First of all, you should inspect the inlet hose - it could accidentally be pressed down by the body of the device ... We also try to open and close the ball valve installed after the tee or on the final section of the supplied pipe. At the same time, we make sure that there is water in the water supply system - for this you need to open the tap above the sink or in the bathroom.
If there is water, we try to check the mesh filter installed in the inlet hose or in the Bosch dishwasher itself. If there are blockages, the mesh should be rinsed or blown out. If there are additional coarse filters in the water supply system, we also check them - they could clog up or simply break.
If water still does not want to enter the dishwasher, we check the functionality of the solenoid valve installed at the inlet to the device. To do this, use a multimeter in voltmeter mode - when the program starts, the supply voltage must be applied to the valve (so that it opens). If there is no current, then the repair will be reduced to replacing the valve.
Bosch dishwashers are reliable and resistant to breakage. However, no one is insured against repairs. If the device stops pouring waste water into the sewer, you need to take action. The drain pump usually breaks here. - it does not differ in particular strength, and if additional loads act on it, then it easily breaks down. Repair technology - complete replacement of a faulty unit.
At the same time, we check the integrity of the connecting wires through which the supply voltage is supplied to the pump. Repair technology in case of breakage detection - complete replacement of wires in compliance with the cross-section. If the noise of the pump is still audible, you need to check its patency and assess the patency of the drain hose - it may have been pinched by something.
Do-it-yourself dishwasher repairs often involve combating leaks. They form in a wide variety of places, causing a lot of trouble. Most enjoyable when the dishwasher is endowed with Aquastopom - this module automatically shuts off the water supply when a leak is detected ... After that, all that remains is to find the leak and eliminate it. However, in some situations, even Aquastop does not help.
Here is a list of possible culprits for leaks:
Working chamber - its metal walls can leak, water begins to drip into the pan. The repair consists in sealing the chamber with soldering or special sealants;
Joints - in Bosch dishwashers, leaks can form at any joint;
Inlet hose - if it breaks through, repairs will be required not only for the dishwasher, but also for the floors (and, God forbid, the neighbor's apartment). In this situation, devices with Aquastop are saved - they control the integrity of the hoses and the presence of water in the pan.
Water cannot flow from any other place.
Repairing a Bosch dishwasher often boils down to finding the source of suspicious noise. Most of all, the situation should be alarming when there was almost no noise, and suddenly it appeared. In this case, you need to urgently find the malfunction and subject the technician to repair. Here's what to look out for:
On the electric motor (aka circulation pump) - here bearings may start to make noise, spoiled by water leaking from under the oil seals ... The repair method depends on the specific situation - sometimes the entire engine changes;
The drain pump is the main source of noise. If she began to rumble louder than usual, then she is about to end;
On the rocker arms and their mechanism - sometimes the noise occurs right here.
Bosch dishwashers usually do not have any other sources of noise.
When repairing a Bosch dishwasher at home, experts often face a lack of water heating. But in this case it is not necessary to call the master, since you can handle the repair yourself. For this we check the integrity of the heating element using a multimeter in ohmmeter mode - the resistance of the heating element should be several tens of Ohms. If it is significantly more or several megohms, then we can state a break - the repair is reduced to replacing the heating element.
You also need to test the thermostat by acting on it with something hot - it should change the ohmmeter reading. Be sure to test the integrity of the wiring through which the supply voltage is suitable for the heater. If there is no current, we check its presence at the output of the control board - if there is silence here, then the problem lies in the board.
Repairs to Bosch dishwashers may be due to a lack of proper drying. If your Bosch dishwasher is equipped with a condensation dryer, make sure you have a rinse aid - it directly affects the quality of drying causing the water to flow downward under its own weight. Condensing drying dries dishes naturally by drying them naturally, so there is nothing to break.
Turbo drying in Bosch dishwashers is more complicated - it consists of a fan and an air heating element. Repair may be required for both the first node and the second, whichever is broken. It also does not hurt to make sure that the supply voltage is supplied to prevent damage to the wiring or the Bosch dishwasher control module.
Your Bosch dishwasher may need repairs even if it is electrocuted. This usually indicates a malfunction of the heating element. heating water.Testing its integrity comes down to measuring the resistance between its contacts and the case. If the resistance is infinitely high, then the heating element is intact - the malfunction should be looked for elsewhere. If the resistance is too small, the heating element needs to be changed - an internal breakdown has occurred in it, and it cannot be repaired.
Do-it-yourself Bosch dishwasher repairs can save you a lot of money. Judge for yourself - just one call from the master will cost from 500 to 1500 rubles. It is also necessary to add the payment for the amount of work and the cost of spare parts for the Bosch dishwasher. As a result, such repairs are poured into a lump sum. Using our instructions, you can save on self-repairing Bosch dishwashers and spend that money on something more enjoyable.
The Bosch dishwasher can be malfunctioning. The machine's self-diagnosis system displays an error code on the display - so the user can find the cause of the breakdown.
What are the most common breakdowns in a Bosch dishwasher? Can you do it yourself? You will find the answers to the questions in the article.
Error codes PMM "Bosch" are collected and described in detail in a separate article.
What factors lead to a breakdown of the dishwasher:
Improper use and connection. Before starting operation, the user does not study the instructions.
Poor quality water with impurities.
Voltage surges in the network.
Installation in a damp room, which affects the electronics and control module.
There are basic types of malfunctions, while you need to pay attention to the behavior of the machine if it does not work correctly.
If the machine does not draw or drain water, the cause may be a blockage in the drain or inlet hose. The filter or drain pump could also be clogged. The reason for the lack of water could be a breakdown of the filler valve.
If the Bosch dishwasher freezes and does not start, or if you have problems washing the dishes, there may be several reasons. If the nozzles or rocker arms are dirty, water does not enter the machine well. Therefore, washing may be ineffective.
How to check the pump and other parts of the dishwasher, read below.
As you understand, common causes of breakdowns are blockages or incorrect connections. Consider how to carry out repairs yourself, without the help of a master.
If water does not flow into the Bosch dishwasher, check the following details:
turn off the water supply;
inspect the inlet hose, it may be pinched;
unscrew the inlet hose and clean the filter mesh.
Additionally, the filler valve is checked - its coils are ringed with a multimeter. In the event of a malfunction, the part is replaced.
If the dishes are poorly washed, the matter is in the clogging of the nozzles, which are sprayed with water from above. You can clean the small holes with a toothpick.
Due to clogging, the water may not be washed off after washing. The machine needs proper maintenance: before loading, the dishes must be cleaned of food debris, otherwise the filter will become clogged. How to fix the situation:
There is a filter at the bottom of the pan. You need to unscrew it and clean it from dirt.
There is a circulation pump behind the filter. In the event of a blockage or breakdown, water is not pumped out of the machine. It is necessary to install a new pump.
The drain hose is also inspected and cleaned.
We sorted out the blockages. Now we will tell you how to fix the PMM if she does not want to wash the dishes.
You have loaded dirty dishes, but the machine does not start drawing water or freezes at all and does not respond to pressing. How to repair equipment:
Check the door lock. The hole that the lock latch fits into may be clogged. Try cleaning it.
With frequent use, the "Start" button could be pressed. Try to disassemble the control panel and put the button back in place.
The most serious malfunction is the control module.The master will be able to diagnose and repair it.
When the dishwasher closes normally, but the wash cycle does not start, the level sensor could break. It cannot be repaired; a complete replacement is needed.
Does water flow into the machine normally but does not heat up? The heating element is defective. For a guide to replacing the heating element, see the video:
VIDEO Abnormal noise during operation may be caused by bearing wear. This is caused by water that seeps through the damaged oil seal. The grease is flushed out and the bearings begin to hum. Only the replacement of bearings and an oil seal will help.
In the article, we examined the main reasons for the breakdown of the Bosch dishwasher. The self-diagnosis system of the machine will help in identifying the problem. If you are not sure that you can fix the equipment, it is better to contact a specialist.
The German quality of household appliances is indisputable, but sometimes such high-quality units break down for one reason or another. Many home craftsmen successfully do self-repair of Bosch dishwashers, the main thing is to correctly determine the cause of the failure and eliminate all its consequences.
Some users, who absolutely do not understand the complexities of household appliances, call service centers for every trifle. But many problems can be solved by yourself:
water does not enter the unit;
water does not drain;
product freezes when turned on.
In the above cases, you can try to reanimate the technique yourself. First check if the water tap is open, then the door is tightly closed, inspect the outlet, maybe the reason is its malfunction. Water may not drain for a reason clogging filters or connection pipes in the drain system. If everything is in order there, you need a wizard to diagnose all nodes.
Does the E15 error code appear on the display? This code signals that a leak has occurred somewhere, so the water intake is stopped - a typical "disease" of this brand of dishwashers. The problem is solved quite simply: disconnect from the mains, then gently tilt the body of the unit to drain the water from the pallet, while float sensor will return to its original position.
When the E15 error code occurs, gently move the car in different directions - this is enough for the stuck float to return to its original state, and the code will disappear from the display.
The second common sore is the gaskets at the junction of the inlet hose with the machine and water supply system. If they are installed incorrectly, then water will seep out, therefore, when connecting the machine, you must carefully read the instructions.
Suspicion immediately falls on the mechanism of the power button: although it is designed for 1 million inclusions, there are different cases due to weak contacts ... If the home craftsman knows how to handle a multimeter, then this is not a problem: ring the contact groups to make sure they are working properly.
It is worth checking the serviceability of the power cable, sockets - sometimes do-it-yourself Bosch car repairs begin with these events. If everything is fine, then you need to test control module ... You can't do this at home - you need a professional technician from a service center who dismantles the necessary part and tests it in the laboratory.
Start button on the control panel
Modern models report themselves malfunction code , the user only needs to check the table in the attached instruction manual to find out the reason. Such a system is quite convenient - all that remains is to repair the dishwasher, focusing on the verdict issued by the machine. The planned start can be interrupted by malfunctions of thermostats, sensors, circulation pump and control system.
We have analyzed one reason in detail - this concerns the Aquastop system, the second may be due to a clogged filter. It can be cleaned quite easily without any special knowledge of technology - we unscrew the inlet hose, carefully pull out the mesh filter and rinse it under running water.
Filling valve located immediately behind the filter may also be faulty, but it is not repaired, but simply replaced with a new device. Details of the repair can be seen in the video, of which there are many on the Internet.
Sometimes this happens: water enters the unit, but the machine freezes in rinsing mode, in this case there are only three reasons:
The drain filter is clogged - it can be easily solved on its own.
The water drain hose is kinked.
The pump requires repair or replacement.
In the first case, everything is simple: at the bottom of the working chamber (tank) there is strainer coarse cleaning, a fine filter element is located nearby. Removal and cleaning will take you no more than 10 minutes.
Find out the status hose you can look behind the car and visually determine its condition, if everything is normal, then the problem is not in it. To get to the pump, you will have to disassemble almost the entire car, since it is at the very bottom, in addition, the car is turned upside down. Typical pump malfunctions - clogging by foreign objects, and the plastic impeller very often breaks or turns on the axis due to blockage by a trapped foreign object.
Important! Replacing the pump is a rather difficult dishwasher repair, so be realistic about your capabilities before starting to disassemble the equipment.
Before replacing the drain pump, it is best to ring the voltage supply wires to make sure they are intact. If you find a defect or breakage, then replace it, but observe the size of the section.
Quite often, users complain about poor-quality dishwashing. The reason often lies in the fact that the operating mode was set incorrectly, but sometimes there is also the fault of the machine due to clogged nozzles or other annoying malfunctions.
All calculation of wash quality is based on rocker arm injectors ... The flow velocity sometimes exceeds 150 km / h, due to the strong pressure, these main elements of the working area rotate and knock down all the dirt and food debris from the dishes with elastic jets.
The main reasons for a weak head are as follows:
clogged holes on the rocker arms;
clogged coarse or fine filter - because of this, the required amount of water does not return to the tank to ensure normal pressure;
temporary wear of the impeller of the circulation pump, so it cannot deliver normal pressure;
low engine speed due to bearing wear and their beats.
It is not difficult for any user to clean the nozzles on the rocker arms, physical force is not required here, on the contrary, it is better not to apply it when removing a fragile product. Rinse the holes with running water, if there are any foreign inclusions, remove carefully with a toothpick.
Note to the hostess! The more food residues you remove from the plates before placing them in the baskets, the less often filters and nozzle openings will clog, without requiring urgent repairs.
Sometimes users complain about the appearance of extraneous noise when working with household appliances. As soon as you encounter such a problem, turn off the machine and start troubleshooting so that repairing the dishwasher does not make a significant hole in the family budget.
In this case, the search algorithm looks like this:
the reason could be circulating pump bearings - water seeped through the oil seals, with all the ensuing consequences, sometimes the pump needs to be replaced;
pump drain may also emit extraneous sounds when the impeller is overloaded or broken;rocker arms and their fastening system, although such a malfunction is very rare.There are no other sources of ambient sound in the dishwashing machine.
Bosch dishwasher repair specialists very often encounter such problems, but the user cannot cope with this on his own if there is no certain knowledge and skills. First of all, you need to be able to work with multimeter in different modes, in particular an ohmmeter.
It is necessary to check the serviceability of the heating element - its resistance should not exceed several tens of Ohms, if much more, then it is possible to accurately assert the presence of a break, you need to change the heating element. Thermostat is also subject to testing, as is all wiring that supplies current to the heater. The lack of current indicates that it is necessary to ring the corresponding outputs from the control unit - not even there, then the problem is in the module. Calling a specialist is inevitable, your master is powerless here.
If the machine is equipped condensation dryer - check the presence of rinse aid, because it strongly affects the drying quality of the dishes, forcing excess water to drain to the bottom of the tank. Drying occurs naturally - there is simply nothing to break here.
In some modes, it does not work, so before indignant, re-read the instructions again. Turbo drying it is more complicated - it consists of a heater through which the fan blows hot air into the working compartment, so both elements must be checked.
Before that, it is worth checking the wiring for integrity and the electronic module for issuing a signal. It is not difficult to repair both elements: one must be replaced immediately, since the heating elements are not repaired, and the second, as the surgeons say, will show an autopsy.
When the car shocks, it is extremely dangerous for all the inhabitants of the apartment and the first signal that somewhere inside there is a broken insulation of the wiring or there is a malfunction of the heating device. Therefore, a short circuit to the case occurs - a thorough check of the entire electrical system is necessary. We already wrote how to ring the element, at the same time it is necessary to check all the wiring and other electrical components in the same way.
Do-it-yourself repair of Bosch dishwashers will cost users much less than calling a service center specialist, which costs from 500 to 1.5 thousand rubles.
Statistics claim that Bosch machines are firmly in the lead in the world in terms of repair costs, and spare parts have astronomical prices. By doing all the work yourself, you can save a decent amount and spend it on something more enjoyable in every way. And this video will help you do everything right.

The good news is that since these dishwashers are so popular, service, parts and repairs are widely available. These household appliances are, in fact, quite simple, so that most of the problems that you may encounter often require fairly simple repairs that you can do yourself.
Here are some tips on some of the most common dishwasher problems you may encounter. For more detailed advice on the Bosch dishwasher, we recommend reading our other articles on this topic.
For example, Power SCRUB PLUS or REGULAR WASH may be called WASH or ECO depending on the dishwasher model and the country you are in. Another important difference is the presence of a display that can display error codes or lack thereof. In this case, the program indicator button will light up to tell you about the malfunction.
As a reminder, model numbers are usually found at the top or ledge of a door.
Hold the POWER SCRUB PLUS and REGULAR WASH buttons to start the test mode. Holding down the ON / OFF button may also help. The indicator above them should be blinking.
Now you can check the status of each program by clicking on the button, or you can start the full testing period.
Press the Power SCRUB PLUS and REGULAR WASH buttons. The electronic device will start, and when the selected mode is over, if you do not have a display, the indicator on your dishwasher model will light up if a malfunction has been detected.
Temperature sensor malfunction. If this is the case, then the test cycle will be very short, as the instrument stops testing as soon as it is detected.
Water / tank fill sensor. If this problem occurs, the test cycle will not be completed because the dishwasher cannot determine the correct water level by simply filling / draining over and over again.
Heating malfunction. Check heating element.
Error codes are interpreted as follows:
0 - no errors were found.
1 - Water sensor or filling failure.
4 - Water filling error. It can also show up as an F on the display during a normal cycle.
8 - Malfunction of the temperature sensor.
When troubleshooting a Bosch dishwasher, performing the above test cycle is a good start in diagnosing the problem. The result will give you an idea of where the problem lies, as well as what repairs will be required to fix the problem.
Make sure the power cable is plugged in correctly and the switch does not operate.
After that, check if the hose is not airy, especially if it was not blown out before installation, it may have air bubbles inside, which retains water.
To do this, disconnect the water supply hose from the dishwasher and run some water through it before reinstalling the hose.
The Bosch dishwasher does not draw water if the previous cycle was interrupted. Reset the dishwasher by pressing and holding the Start button for at least three seconds.
Depending on the model, you can also click the "Cancel-Reset" button to reset. Select a new cycle and click "Start".
Check the water supply hose under the sink. If it was turned off or blocked for any reason, the dishwasher will give a program error and will not be able to fill the tank with water, even if the water supply is resumed within a few seconds.
Most Bosch dishwashers have a small filter inside the hose to prevent foreign particles from the water supply from entering the dishwasher.
Disconnect the hose and remove the filter inside. Then clean it thoroughly to remove any third-party elements and reinstall it.
Make sure you have enough water pressure to start the dishwasher and pump.
To check, take a 4L container and turn the tap all the way to fill it. If you have enough water pressure to start the dishwasher, the container should fill within 30 seconds.
Unplug the power cord from the outlet or turn off the power to the device using the machine.Remove the panel by unscrewing the two screws on both sides.
Detach the screws that hold the front door panel inside the dishwasher; pull the door panel down and set it aside.
Close the door to access the water intake valve. The filler valve has two wires that connect it to the block diagram. Check to make sure they are securely fastened.
Also check the valve for damage or leaks. If damaged, buy a new one using your dishwasher model number and replace it; otherwise, have your technician do it for you.
