Repair faults dishwasher Bosch

The German quality of household appliances is indisputable, but sometimes such quality units break for one reason or another. Independent repair of Bosch dishwashers is successfully done by many home craftsmen, the main thing is to correctly determine the cause of the failure and eliminate all its consequences.

Possible diseases of technology

Some users who absolutely do not understand the difficulties of household appliances, for every trifle call the service centers. But many problems can be solved independently:

• water does not flow into the unit;
• water does not drain;
• The product freezes when turned on.

In the above cases, you can try to reanimate the technique yourself.First check whether the water supply valve is open, then the door is tightly closed, inspect the outlet, maybe the reason is its malfunction. Water may not go away due to clogging filters or nozzles connections in the drain system. If everything is fine there, you need a wizard to diagnose all the nodes.

Error code E15 appears 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 dishwasher. The problem is solved quite simply: disconnect from the network, then gently tilt the body of the unit to drain the water from the pan, while sensor float will return to its original position.

When an error code E15 occurs, move the machine gently in different directions - this is enough for the stuck float to return to its original state and the code will disappear from the display.

Error E15

The second common sore - gaskets at the junction of the filler hose with the system of the machine and water supply. If they are installed incorrectly, the water will leak, so when you connect the machine, you should carefully read the instructions.

The machine does not turn on

Immediately suspicion 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 master knows how to handle a multimeter, then it’s not a problem: ring up contact groups to make sure they are working.

It is worth checking the serviceability of the power cable, sockets - sometimes repairing a Bosch machine with your own hands begins with these events. If everything is in order, then you need to test control module. Do not do this at home - you need a professional master from a service center who dismantles the necessary part and tests it in the laboratory.

Does not start after start

Modern models report themselves trouble code, the user needs to check the table in the attached instruction manual to find out the cause. Such a system is quite convenient - it remains only to repair the dishwasher, focusing on the verdict issued by the machine. A scheduled start may be prevented by faults in thermostats, sensors, circulation pump, and control system.

Water does not flow and does not drain.

We have disassembled one reason in detail - this concerns the Aquastop system, the second one may be due to filter clogging. With its cleaning, you can quite easily cope without any special knowledge of technology - unscrew the bay hose, carefully pull out the strainer and rinse it under running water.

Filling valvelocated immediately behind the filter may also be faulty, but it is not being repaired, but simply replaced by a new device. Details of the repair can be viewed on the video, which are many on the Internet.

Sometimes this happens: water enters the unit, but the machine freezes in the rinse mode, in this case there are only three reasons:

1. The drain filter is clogged up - it is easily solved on its own.
2. There was a bend of the drain hose.
3. Pump requires repair or replacement.

In the first case, everything is simple: at the bottom of the working chamber (tank) there is strainer rough cleaning, located next to the filter element fine cleaning. It will take you no more than 10 minutes to remove and clean.

Find out the state hose You can, looking behind the car and visually determine its condition, if everything is normal, then the problem lies not in it.To get to the pump, you have to disassemble almost the entire machine, since it is at the very bottom, except that the machine is turned upside down. Typical pump malfunctions - contamination by foreign objects, and the plastic impeller often breaks or rotates on the axle due to blockage by a foreign object.

Important! Replacing the pump refers to a rather complicated repair of the dishwasher, so really assess your capabilities before proceeding with the disassembly of equipment.

Before replacing the drain pump, it is better to ring the supply wires to ensure their integrity. If you find a defect or breakage, replace, but observe the size of the cross section.

There is no quality dishwashing

Quite often, users complain of poor-quality washing up. The reason often lies in the fact that the mode of operation was incorrectly set, but sometimes there is a machine fault due to clogged nozzles or other annoying faults.

The entire calculation of washing quality is based on nozzles rocker. The flow rate sometimes exceeds 150 km / h, due to the strong pressure, these basic elements of the working area rotate and force all the dirt and food residue off with elastic jets.dishes

The main causes of low pressure are as follows:

• blockage of the holes on the rocker arms;
• coarse or fine filter clogged - 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 circulating pump, so it can not give normal pressure;
• low engine speed due to bearing wear and their beats.

Cleaning the nozzles on the yokes is not difficult for any user; physical strength 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 extraneous impregnations - remove carefully with a toothpick.

Mistress on the note! The more food residues you remove from the plates before putting them in the baskets, the less often filters and nozzles will become clogged, without requiring urgent repairs.

Noises

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 the repair of the dishwasher does not break a significant gap in the family budget.

In this case, the search algorithm is as follows:

• the reason may be circulating pump bearings - water leaked through the glands, with all the ensuing consequences, sometimes it is necessary to replace the pump;
• drain pump It may also make extraneous sounds when the impeller is overloaded or broken;
• rocker and their fastening system, although such a failure is very rare.

There are no other sources of extraneous sound in the dishwashing machine.

Circulation pump

Water does not heat up

Bosch dishwasher repair specialists very often encounter such problems, but the user cannot cope with this on his own if he does not have certain knowledge and skills. First you need to be able to work with multimeter in different modes, in particular ohmmeter.

It is necessary to check the serviceability of the heating element - its resistance should not exceed several tens of Ohms, if it is much more, then it is possible to ascertain the presence of a break, it is necessary to change the heating element. Thermostat also be tested, as is all wiring that supplies current to the heater.The absence of current indicates that it is necessary to ring the corresponding outputs from the control unit - and there is no, this means a problem in the module. The call of a specialist is inevitable, his master is powerless here.

Does not dry dishes

If the machine is equipped condensing type drying - check the presence of the rinse, because it strongly affects the quality of drying dishes, forcing excess water to flow to the bottom of the tank. Drying occurs naturally - there is simply nothing to break here.

In some modes, it does not function, so before resenting, re-read the instructions again. Turbosushka it is more complicated - it consists of a heater through which the fan pumps hot air into the working compartment, so you need to check both elements.

Before that, it is worth checking the wiring for integrity and the electronic module for signal output. Repairing both elements is not difficult: one must be replaced immediately, since the heating elements are not repaired, and the second, as the surgeons say, “will reveal the autopsy”.

Current leakage

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 - careful inspection of the entire electrical system is necessary. How to ring the element we have already written, at the same time it is necessary to check in the same way all the wiring and other electrical components.

Do-it-yourself repairing dishwashers of the Bosch brand will cost users much less than calling a specialist from a service center that costs between 500 and 1.5 thousand rubles.

The statistics asserts that Bosch cars by the cost of repairs occupy a firmly leading place in the world, and spare parts have astronomical prices. By doing all the work yourself, you can save a decent amount and spend it on something more pleasant in all respects. And this video will help to do everything right.
