Regardless of whether the dishwasher is still under warranty or not, for no reason any of them can stop drawing water. And there can be many reasons for this. If water does not enter the Bosch dishwasher that you purchased no more than a week ago, it makes sense to simply exchange it in the store for a new one. If the warranty period has expired, no one will repair it for free anyway. So maybe then it makes sense to look for the cause yourself, and having found it, eliminate it yourself, thereby saving a considerable amount of money?
What does "no water flow" mean?
Until water starts to flow into the dishwasher, none of the subsequent cycles of its program will work. Everything is correct. The sensor does not detect the presence of liquid in the unit, and the automation will not start the program. And why? The machine does not know how to wield air.
But the owners of the units are more interested in the question, does not the fact that water does not enter the dishwasher indicate the failure of the main processor itself? Indeed, in order to replace it with a serviceable unit, the service center will charge a fee almost the same as the cost of the device itself. But don't panic. Microcircuits on such devices are reliable, rather it is either in plumbing, or in some kind of “wires”, as the craftsmen like to say.
Main reasons why water refuses to fill the dishwasher
The most common reasons why water does not enter the dishwasher are:
- Failure of the sensor on the locking mechanism of the door. There is no contact, the circuit is not closed, and, as they say, "the train will not go further." The processor will think that the door is still open and will refuse to draw water.
- Failure of the water set sensor. Although it can rather be called the “incorrect” operation of the pressure switch. If he sends some intermittent and incomprehensible pulses to the processor, which he will not be able to decipher, he will not collect water.
- Clogged water filter. Sometimes it happens. The blockage has caused a blockage, and water does not flow into the dishwasher or it barely flows. In this case, the unit will also refuse to work.
- Faulty inlet valve. At first, after connecting, the machine will not work if it is connected incorrectly. In this case, you need to double-check everything and do it again according to the instructions.
All these problems can be fixedpersonally, the main thing is to find what the root of evil lies in, that is, to identify the reason why water does not enter the dishwasher. Of course, it happens that the control system also fails, but these are quite rare cases, and here, in reality, only a service center will help, since you can only replace the panel with a new one yourself.
It will hardly be possible for an ignorant person in electronics to repair the panel. In addition, in order to solder any microcircuit, special devices are needed that the average layman does not have. But let's not guess, let's first inspect the unit.
Looking for a reason
In general, each dishwasher, regardless of brand and manufacturer, is similar in structure and principle of operation. And therefore, regardless of whether water does not enter the Electrolux dishwasher or a machine of a different brand, the process of finding and eliminating the root causes is always the same. And this search should begin with the most trivial actions:
- Checking the intake valve, maybe it's blocked;
- determining the presence of water in the water supply system;
- Checking if the door is tight.
If the inlet valve is open to the full, the water in the tap is flowing, the door is closed tightly, as it should be, but the water still does not want to be drawn, we start looking for more hidden problems.
Failure of the sensor on the locking mechanism of the door
Anyone can immediately tell how the door closed before and how the lock works now. If there is no characteristic click and the closure is sluggish or incomplete, then all the s alt is in the lock. The easiest way is to order a part in a store and replace it yourself by disassembling the door of the unit. As a rule, such locks are not subject to repair, they are simply replaced with new or used ones, but still functioning.
If the door clicks and the door closes perfectly, but the dishwasher does not get water anyway, look for a breakdown elsewhere.
Clogged filter on supply valve
It often happens that water does not enter the Indesit dishwasher due to the usual blockage of the inlet filter. To diagnose this breakdown, you will have to move the machine away from the wall and, having previously shut off the water supply with the locking tap, unscrew the water supply hose to the machine and inspect the filter mesh.
Often, excessively hard water leads to the formation of persistent blockages. If a blockage is found, it should be cleaned and, screwing the hose into place, start the program. If the water has gone, the repair is over. If not, we look for the reason further.
Intake valve failure
The resource of the inlet valve in branded models is very large, but sometimes the steel breaks, as a prose writer would say. And with the inlet valve the same problem as with the lock in the door. This part is not repaired, but replaced with a new one. It can alsoorder in a store or the Internet and change it yourself. Or you will have to take the machine to a service center.
Pressostat (water level sensor) and main control processor
So, water does not enter the dishwasher, the reasons associated with plumbing have been discussed, the electronics remain. Alas, this issue is solved only by replacing parts. But before you decide on this replacement, you should first make a diagnosis. It doesn’t cost anything for a person who is knowledgeable in radio engineering to ring out the details, but for this you need to know the indicators that this or that part gives out, being in working condition.
Each brand of dishwasher has its own sensors, and they glow differently on the multimeter. Only a specialist who is knowledgeable in these matters can diagnose a breakdown of the pressure switch, or, again, you will have to take the unit directly to a service center. With the control panel the same song. Schemes for them in the free distribution can not be found. And messing around blindly will be useless.
Continuity of conductors
Sometimes the wires that go from the sensors to the control panel fail. If you are too lazy to mess around, you can move the machine away from the wall, opening access to the back wall, disconnect the unit from the mains and water supply, and remove the back wall by unscrewing the corresponding fasteners with a screwdriver or screwdriver.
Finding the water level sensor is not difficult by the wires that go to it. Armed with a multimeter, set it to a simple continuity and ring all the wires in turn, not only from thissensor, and any that catch your eye and seem suspicious from the node to which they go to the soldering to which they come to the control panel board. Having found a worthless non-ringing wire, you should replace it with a new one.
If desired, you can make a dial by disconnecting the plugs from the panels and sensors. Maybe the problem is with them. Sometimes copper contacts can oxidize and become unusable from high humidity. In this case, it is worth checking everything, cleaning it and, having connected all the plugs in their places, reassemble the machine, connect it to water and power supply and start the program. If everything works, you are great. If it doesn't work, then it's still a good job. At least they tried. But now call the service center.
Conclusion
The reason why water does not enter the dishwasher may have a non-standard reason. For example, some capacitor or resistance on the control board has failed somewhere. Maybe some other, not noticed by you, contact has departed. You can learn about another non-standard reason from the following video.
It happens that the door mechanism snaps into place, but it is still not all right with the electronics. There is only one verdict. If water does not enter the Bosch dishwasher (or any other) and the reasons are not in the plumbing and the problems listed above, then otherwise you are powerless. Call the master. He will find everything and fix everything.
