If the dishwasher does not turn on, then do not rush to panic and call service. Let's try to figure out what's what together. Perhaps it's not so scary!
The main causes of the malfunction
How annoying it is when, after loading a full basket of dirty dishes, you press the coveted start button, hoping to go to drink coffee, but the faithful assistant refuses to work. Moreover, categorically!
What's the matter? The reason may turn out to be absurdly stupid, for example: one of your household members for some reason pulled the cord out of the network ... Or, moving the machine a little while cleaning, somehow put the same cord under it and it broke from being transferred by a large weight technology.
It so happens that the point is not in the typewriter at all, but in the burnt-out outlet to which it is connected.
If so, then it's not that bad. In the first case, you just need to insert the plug into the outlet, in the second, replace the cord, and in the third, reconnect the unit to another power source.
But, there are breakdowns and worse and the repair comes out - more expensive. If the first three reasons are not your case, still remain calm and only calm. You will always have time to call the master, and it did not harm anyone to carry out the diagnosis yourself.
We present you with a list of the main reasons why the dishwasher does not start:
- The cord is broken in an inconspicuous place
- The lock on the door is faulty
- The "start" button is faulty
- Fuse blown
- Water does not flow into the chamber
- Broken control unit
- Burned out motor or relay
- Clogged pump
- The water supply hose is squashed
In general, these are the main causes of breakdowns. Moreover, the third part of them falls on the blown fuses.
Now let's take a closer look at the symptoms of these popular malfunctions and it may be possible to independently determine why the dishwasher does not start and the reasons for this.

If the machine does not turn on at all
In this case, only such reasons are possible, from the general, above list:
- Broken cord
- Burnt capacitor
- The lock on the door is faulty
- Defective button
- Defective program unit
- Burned out motor or relay
Start diagnostics in order, with the cord.
Cord
To do this, you need to arm yourself with a multimeter. We set the ohmmeter mode on it and connect the probes to the wire sections of interest.
If you find that some part of the wire is burnt out, then you should not save and change it by inserting a new piece. Any twists and adhesions are fire hazardous and unreliable. And this can lead in the future to a fire or more serious damage inside the car.
Fuse blown
To diagnose the capacitor, you will need to disassemble the machine. Beforehand, we recommend covering the floor with a rag, since residual water may flow from the unit.
The fuses are located in a circular pump under the pallet. Therefore, you must parse it by following this procedure:
- Remove the panel in front, located under the door of the machine
- Remove the side brackets from the pallet
- Open the door, unscrew the debris filter and remove the impeller
- Close the door, turn the machine over and remove the pallet
- Find the fuse on the circular pump
- We check the resistance with a multimeter.
If you find that the fuse is defective, you need to find an absolutely identical one and replace it.
The lock on the door is faulty
This is the easiest to diagnose. Either the door is closing or not. If not…
Here, of course, nothing can be done ... You cannot do without calling the master, moreover, with a service that has the necessary detail. Of course, if you are very well versed in such breakdowns and know how and with what you can replace a broken door spare part, then you are in luck!
The start button is faulty
If you do not clearly see that the button looks strange, then it is unlikely that this is the case. Most likely, in other electronics, that is, the control unit. But, if the button has sunk or dangles, then she is the culprit. Look for the necessary spare part, change or call the master.
Defective program unit
This is perhaps one of the nastiest and most expensive breakdowns. The repair is quite expensive and you will not do anything on your own. We'll have to completely change the block. But, do not rush to sin on him prematurely, until you check absolutely all possible options.
Burned out motor or relay
The machine will need to be disassembled and checked for electrical conductivity with a multimeter.
If they burned out, it’s bad ... These are expensive parts, of course.
If the engine hums but the dishwasher does not start
- Clogged pump
- Clogged motor
- The water supply hose is squashed
The first step is to check the hose. If it is in its normal state, that is, not twisted, then proceed to inspect the "insides".
If there is no visible contamination, then that is not the reason. If obvious dirt is present, clean the parts and try to start the machine again.
Features of Bosch machines
The brand is popular and quite beloved by the people. Still, nobody canceled the German quality.
But, if the Bosch dishwasher does not start, then the reasons may be slightly different than in other cases. Its design is slightly different.
Therefore, if you have checked all the diagnostic options we have proposed, then you should call the Bosch service center and find out the details.
Recommendations for use
Do not neglect the rules described in your instructions for the typewriter. You shouldn't change special salt for table salt, and special tablets for dishwashing detergent with your hands ... Such strange savings will come to you sideways and the question "Why the dishwasher does not turn on" will not keep you waiting long.
