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 arranged not so difficult as it seems at first glance. Do-it-yourself Bosch dishwasher repairs are done by many people. The main thing is to learn how to understand the basic malfunctions, which we will talk about in this review-instruction.
Dishwasher won't turn on
Repair of Bosch dishwashers is carried out in the same way as the repair of any other dishwashers - they are arranged in approximately the same way. And the simplicity of the design allows you to count on success in 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. The contact groups here are weak, therefore, breakdowns occur frequently. Repair is preceded by testing the button - you can measure the presence of voltage at the output or test the performance of the contact group with a multimeteroperating in ohmmeter mode.
We can also suspect other components of the Bosch dishwasher in 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 against him.
Dishwasher won't start washing dishes
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 running programs, then the repair is preceded by a thorough check of the equipment. 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.
Lack of start may be caused by other malfunctions. If the dishwasher is modern, it will show an error code. Looking at the table with codes, you will understand what exactly is out of order. This diagnostic scheme is particularly convenient, as it allows you to quickly calculate the faulty node. You will only have to carry out repairs, focusing on the data obtained during the diagnostics.
Water does not enter the machine
We are trying to calculate the malfunctions of Bosch dishwashers in the absence of normal water pouring. 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 incoming pipe. At the same time, we make sure that there is water in the plumbing - for this you need to open the tap above the sink or in the bathroom.
If there is water, we try to check the strainer installed in the inlet hose or in the Bosch dishwasher itself.In the presence of blockages, the mesh should be washed or blown. If there are additional coarse filters in the water supply system, we also check them - they could become clogged or simply break.
If water still does not want to enter the dishwasher, we check the operability of the solenoid valve installed at the inlet to the machine. To do this, use a multimeter in voltmeter mode - when the program starts, the valve must be supplied with voltage (in order for it to open). If there is no current, then the repair will be reduced to replacing the valve.
The machine does not drain water
Bosch dishwashers are reliable and resistant to breakage. However, no one is immune from repairs. If the device has stopped draining waste water into the sewer, you need to take action. Usually the drain pump breaks here. - it is not particularly durable, and if additional loads act on it, then it easily fails. Repair technology - complete replacement of a faulty unit.
At the same time, we check the integrity of the connecting wires through which the pump receives the supply voltage. Repair technology in the event of a break is a 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 evaluate the patency of the drain hose - perhaps it turned out to be something clamped.
dishwasher leaking
Do-it-yourself dishwasher repair often involves fighting leaks. They form in a variety of places, causing a lot of trouble. The most pleasant thing is when the dishwasher is endowed with Aquastop - this module automatically shuts off the water supply when a leak is detected. After that, it remains only to find the leak and eliminate it.However, in some situations even Aquastop does not save.
Here is a list of possible culprits for the formation of leaks:
- Working chamber - its metal walls can leak, water begins to drip into the pan. Repair consists in sealing the chamber with soldering or special sealants;
- Connection points - in Bosch dishwashers, leaks can form at any connecting joints;
- Inlet hose - if it breaks, 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 save - they control the integrity of the hoses and the presence of water in the sump.
Water cannot flow from any other places.
Noise in the dishwasher
Repairing a Bosch dishwasher often comes down to finding the source of suspicious noises. Most of all, the situation should alert when there was almost no noise, and suddenly it appeared. In this case, you need to urgently find the malfunction and subject the equipment to repair. Here's what to look out for:
- On the electric motor (aka circulation pump) - bearings can start to make noise here, spoiled by water leaking from under the seals. The method of repair depends on the specific situation - sometimes the entire engine changes;
- On the drain pump - this is the main source of noise. If she began to rumble louder than usual, then she was about to come to an end;
- On the rocker arms and their mechanism - sometimes noise occurs here.
There are usually no other sources of noise in Bosch dishwashers.
Dishwasher does not heat water
When repairing a Bosch dishwasher at home, specialists often encounter 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 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 larger or amounts to several MΩ, then we can state a break - the repair comes down to replacing the heating element.
You also need to test the thermostat by exposing it to something hot - it should change the ohmmeter readings. Be sure to test the integrity of the wiring, through which the supply voltage is connected to 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.
Dishwasher won't dry dishes
Repair of Bosch dishwashers may be due to the lack of proper drying. If your Bosch dishwasher is equipped with a condenser dryer, you should make sure that there is rinse aid - it directly affects the quality of dryingcausing the water to flow down under its own weight. The condensation dryer dries the dishes by natural drying, so there is nothing to break.
The turbo dryer 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, depending on what is broken. It also does not hurt to make sure that the supply voltage is supplied in order to prevent damage to the wiring or control module of the Bosch dishwasher.
Dishwasher is electric
A Bosch dishwasher may also need to be repaired if it is electrocuted. This usually indicates a malfunction of the heating element.for 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 sought elsewhere.If there is too little resistance, the heating element needs to be changed - an internal breakdown has occurred in it, and it cannot be repaired.
Do-it-yourself Bosch dishwasher repair can save you a lot of money. Judge for yourself - just calling the master will cost from 500 to 1500 rubles. To this must be added the payment for the volume of work and the cost Bosch dishwasher parts. As a result, such repairs result in a round sum. Using our instructions, you can save on your own Bosch dishwasher repair and spend that money on something more pleasant.
