Repair of the dishwasher with your own hands and fault codes PMM

With the development of progress, a person tried to simplify life in every way. For help in solving familiar household cases, such as: washing, cleaning and washing the dishes, modernized mechanisms have come, capable of significantly simplifying the whole process. Instead of a broom, a vacuum cleaner appeared, instead of a trough - washing machine. These changes were also touched upon and washing the dishes, which became much easier and faster thanks to the dishwasher. However, like all other household appliances, such a mechanism is able to fail. To fix everything in a specialized workshop, you will have to spend not only for the delivery of heavy PMM, but also for its immediate repairs. An excellent solution will be the independent repair of the dishwasher, which will be for everyone.

Principle of operation of dishwashers

PMM simplifies the process of washing the dishes, turning it into a pleasure. Pull the detergent, select the desired mode and press the button, and after some time your dishes will be clean, and the main thing is dry. Agree - it's nice, besides will not take much difficulty. Unfortunately, the car needs to constantly maintain - setting, replacing filters and other consumables. To rather reveal and eliminate the problem, it is not bad to know the dishwasher device. Summing up the principle of operation, you can appreciate the complexity of the technological process within the instrument.

The dishwasher works on the following principle, while each action is accomplished in stages in such a sequence:

1. Pre-sink. Water enters PMM under pressure through a special intake valve. At this stage, water removes large residues of food from the surface of the dishes. Dirt settles in special filters, which can be subsequently replaced. At this stage, the detergent is gradually the detergent in accordance with the dosage of a particular program.
2. Main car wash. Through the pipe water pipe through a special salt filter, water enters the system of PMM. As a regulator, the amount of water is the float, which is triggered by the pressure switch. Thus, when the water rose to the desired mark, the heating begins in accordance with the desired temperature and the washing mode. Dirty water is filtered several times, after which it comes into the next cycle.
   
3. Rinsing. At this stage, the water is heated to a high temperature, after which it enters the sink area by means of a special pump. Splinker nozzles spray water under pressure by rotating the impeller. Hot water not only kills the remaining bacteria, but also significantly speeds up the drying process.
4. Drying. At this stage there are two options for drying, it all depends on the company and modifying the dishwasher. If your PMM has a turbosushki mode, then the whole process is due to the fan, which drives out all the hot air outwards. In the second case, a condensation drying method is used, which occurs due to the residual temperature resulting in the rinsing process. Thus, steam simply flows through the walls into the drainage system.
5. Drain. At the final stage, all dirty water is deleted into the sewage system.

At first glance, the device PMM may seem quite uncomplicated. All firms and models of such devices have a similar principle of operation, but in pursuit of new technologies, some things are modified.

The main causes of dishwasher breakdowns

Almost any electromechanical devices have weaknesses, dishwashers in this case are no exception. If you are going to do repairs yourself, it is better to immediately pay attention to the most basic problems that can meet in your PMM. Perhaps the breakdown is not so serious.

Most often, dishwashers fail for the following reasons:

• voltage drops on the network. This is possible if you have not secured the device with an additional circuit breaker or the quality of wiring in the apartment leaves much to be desired;
• incorrectly selected or poor-quality detergents. You may have used the means for washing the dishes are not as appointed or used overdue goods;
• increased rigidity of water. As well as in washing machines, the high content of mineral salts in water can cause scale. Fine particles contained in water can eventually settle in the system;
• bad care for the device. If you do not change the filters and "consumables" for a long time, then breakdowns are not avoided;
• incorrect installation of the PMM. It may also affect the efficiency of the device due to negligence during installation. You may have used the services of an incompetent worker;
• damage to sensors. The PMM system works in a sufficiently dirty aggressive environment, and over time, the sensors are contaminated, up to the full stop of the entire washing cycle.

When you are going to install everything with your own hands, it is better to carefully examine the instructions. It will help you determine the correct connection scheme to avoid troubleshooting during operation. After all, most often the "dishwasher" fails, because filters, nozzles, valves and other mechanisms of the device are clogged. Carefully monitor the voltage within the network, as well as water pressure when feeding and draining the sewage. It is better to carry out regular service with the replacement of all necessary "consumables" than then get an impressive check from the repair company.

Repair of the dishwasher do it yourself. Diagnostics and troubleshooting dishwashers with their own hands

If you spent diagnostics correctly, that is, I revealed the reason for the inoperability of the PMM, then it's time to proceed to the direct repair of the device. We advise you to immediately get a set of screwdrivers of different diameters, a multimeter, as well as laying and pliers. With this set of tools, repairs will pass much easier and faster. Since all cases have an individual approach to solving the problem, it is better to disassemble every problem in detail.

Repair of the dishwasher do it yourself. Lack of reaction to press buttons

If there is no indication on the control panel of the dishwasher, then there is most likely there is no voltage in the network. To check this, use the multimeter that measure the voltage in the outlet. Perhaps it fell, then the PMM will not even turn on. Then you need to check the quality of the wiring. It happens that the circuit breaker has worked, then it must be turned on again.

If the display still functions, and the "dishwasher" does not respond to the press of the buttons, then you need to check the door. It happens that it is bad closed, then a special sensor does not allow the PMM to fulfill further commands. A loosely closed door can be accompanied by a warning signal. If after these actions nothing happened, then disassembly can not be avoided.

If the previous actions did not help to eliminate the problem, then they are applied as follows:

1. By revealing all the fasteners, remove the front panel of the dishwasher.
2. Find the junction box, and open it. It is designed to distribute the incoming voltage in the instrument system. This is happening by terminals that can clog or oxidize, since they are in a wet environment.
3. Remove the bolts on the terminals to remove the wires. Using sandpaper, clean the terminals, then connect the contacts in the same sequence. Check the contacts for damage and deformations.
4. If it did not help, then you need to "ring" the entire chain to reveal the damaged area. Wires that suit the box from the network are disconnected, after which they check the multimeter. Note that the PMM power supply must be disconnected, and the water is merged.
5. If the measuring instrument showed the integrity of the conductor, then it will have to continue to repair. In the opposite case, it is enough to buy a cable of the required length with the corresponding parameters, and replace it.
6. If you still risked, and decided to go "further", we advise you to start finding the electrical scheme of your dishwasher in the attached instructions or on the Internet.
7. After that, sequentially check the circuit with the tester for the presence of breaks. The locations of the compounds in the diagram are usually indicated by small circles, and measurements are carried out. If several elements are combined with a barcompound line, then they are placed in a common unit, for example, a start-up relay or display.
8. When the links of the electrocups are not "nicknamed", they are replaced by the corresponding terminals, devices or wires.

"Nickname" electrical chain, move consistently. Check each site carefully to detect the problem. Please note that for the performance of any element in the chain, it is necessary that "+" connected with "-". Sometimes it is possible to externally determine that one of the capacitors or resistors blocked or the device has failed. Best patience, and the result will not make you wait.

Repair of the dishwasher do it yourself. There is no water supply

When you opening the feed crane, found that water does not enter the dishwasher system, then, most likely, the problem in the valve. There is also a chance that the filter has been hampered.

In this case, the repair is carried out as follows:

1. Expand PMM to get to the valve. It is at the bottom of the reverse side of the device. Discharge water supply.
2. Disconnect the "dishwasher" from the pipe.
3. Remove the filter, and rinse under the water stream. If it is unsuitable - replace the new one.
4. Disconnect the outputs on the valve coils to which the voltage is suitable. Check the valve with a tester.
5. If it shows the zero resistance, then, most likely, inside the winding occurred.
6. If the resistance is small, then the malfunction inside the valve.

If the filter cleaning did not help, and the valve performance check did not give positively, the device is better replaced. Note that it should have the appropriate parameters and the size so that you can easily install it on the old place.

Repair of the dishwasher do it yourself. Water does not merge at the end of the sink

Such a malfunction most often occurs in the event that the drain of the sewer pipe is clogged.

To reveal and fix the problem, go as follows:

1. Disconnect the drain pipe from the sewage system. If she is clogged - clean.
2. Also, the reason may be in the drain pump. Pull it out and write it easier. If it does not function, the pump is checked with a multimeter.
3. Check all filters for contaminants. Clean or replace them if necessary.
   

Repair of the dishwasher do it yourself. The machine is operational, but the car wash does not begin

If you can enable your PMM, the display works, the water is recruited, and the first cycle of the washing does not begin, then you need to do the following:

1. Listen to the electric motor. If he begins to make sounds that you have not heard before, then, most likely, the malfunction is in it. An option is also possible that the pump jammed, as a result of which the engine cannot function.
2. It happens that the engine winding is damaged. Then you need to disconnect the conclusions, after which it is tested using a multimeter. The result will help to identify areas for the break of the winding, or on the closure between the turns. Then you will have to completely replace the electric motor, or call a specialist so that it rewind the engine coil. Make a rewind on your own very difficult, it is better to entrust this business to a professional.
3. If you are implementing the dishwasher in Indesit's own repair, then in case of engine failure and soundtowing during its launch, try to find a power supply of the device. Armed with a tester, "ring" all sections of the chain to identify damaged items.
   

Repair of the dishwasher do it yourself. Water stopped heated

In case of such a malfunction, there are several reasons, each of which has a different way of repair and diagnostics.

The lack of water heating in the dishwasher may be caused by the following reasons:

1. Heated heating element (TEN). In this case, it is enough to disconnect the TEN, after which it is a test multimeter. If the resistance is detected, we buy a new heater.
2. The temperature sensor and timer do not function. To determine the problem in this case is quite problematic, because it will be necessary to track the entire sequence of contacts from the timer to the Tan. In this case, it is better not to risk, but to contact a specialist.
   

Repair of the dishwasher do it yourself. Dishwasher publish strange sounds

If your device began to make noise louder than usual, then at the first problem of such a kind, it is better to stop the sink process. Most likely, the fragments of glass or metal got into the system. This happens when the bearings have already worn out. You will immediately understand this, because the quality of washing will significantly decrease. In addition, the impeller on the pump can be deformed or fail. In any case, it is better to disassemble the engine, and check the items. In this case, it is enough to replace the worn items new. After replacing your engine should work smoothly and gently, without third-party sounds.

Repair of the dishwasher do it yourself. Reverse stopped hardware

The main reason for such a breakdown can be a break of the winding on the electric motor coil. It is enough to replace the coil independently, or contact the service center for the help of a specialist. Recall once again that it is better not to re-wind with your own hands. There are also cases that the reverse is absent due to the failure of the timer. In any case, if you discovered such a breakdown, we advise you to entrust the repair of the dishwasher, be it Bosch, Electrolux, Indesit, Zanussi, or any other manufacturer of specialized service centers.

Repair of the dishwasher do it yourself. Dishwasher gives leak

For such a problem, there are several reasons for the occurrence that are solved quite simply. You need to visually inspect the place of leakage. If water is pouring from the door, then the sealer was most likely worn out. In this case, it is enough to replace it with a new one.

If the leakage on the reverse side of the dishwasher, then there may be several options:

1. The feed hose is damaged, and water seeps through the crack.
2. Sealing gasket pump is deformed.
3. Damage in the drain system.

Eliminate such problems is easy enough, you only need to replace hoses and gaskets. After you have installed new items, you will definitely clamp them with clamps. This will help to further avoid new leaks.

Repair of the dishwasher do it yourself. "Dishwasher" stopped drying dishes

Such a malfunction is most often found in PMM, equipped with a turbosushki function. With a high probability, you simply break the winding on the fan. If with visual inspection, you found that the winding remained the whole, then the case in the inclusion circuit. Then take the tester and check the inclusion terminals. If necessary, replace the fan. It is possible that dust accumulated on the terminals, then it is enough to clean them.

As you can see, make a separate repair of dishwasher any firm simply enough, it is important to know some features, and have a master of possession of a multimeter. We brought you an example of the most common problems in the PMM, which you can diagnose and repair your own hands. If your actions have not led to the desired result, it is better to contact the service center. In addition, under warranty you have to repair for free. We also advise you to pay attention to the common fault codes that will help instantly identify the reason for the dishwasher in a dishwasher or another manufacturer.
