Dishwasher is an indispensable unit that can greatly facilitate the work of the hostess in the kitchen. But if you have been using the dishwasher for a long time, various malfunctions may appear: in this case, your dishwasher will need to be repaired. From this is not insured any household appliances, and the brand does not play any role.

Common Damage

The following factors can cause the most common malfunctions of the device:

• substandard parts on cheap models of machines;
• poor cleaning of dishes before loading often causes the dishwasher to become clogged (filters are dirty);
• the use of third-party or low-quality detergents (poor washing of dishes);
• a loose door may cause water leakage (factory failure is not excluded);
• improper loading of dishes (poor-quality washing).

In addition, they may fail. different PMM nodes: temperature sensor, circulation pump, various valves and other components of the apparatus. But there are also frequent faults that are specific to certain brands of dishwashers. This information is taken from the statistics of service centers for the repair of household appliances. Below we consider the characteristic faults for various brands of dishwashers.

Hansa

The main malfunction of the Hansa PMM, according to statistics from service centers, is the failure of the water level sensor. Often in the pressure switch the electric part burns out, so it needs to be changed to a new one. But before starting the repair of Hansa dishwashers, it is necessary to determine the sensor failure by the following symptoms:

• dishwasher constantly picks up and drains water;
• Hans’s machine draws less water than needed;
• the unit is gaining fluid more than normal;
• PMM stops the program, and stands without pumping water.

If at least one of the symptoms occurs, then disassembly of the apparatus will be necessary to remove the sensor. But this procedure for repairing or replacing a sensor is best left to the master: he knows the whole pressure switch test algorithm on serviceability.

AEG

According to experts who repair AEG dishwashers, the units of this company frequent failures due to failure of the drain pump. To find out what exactly the pump was the culprit for the failure, you can on some grounds:

• the pump engine makes sounds, but at the same time water from the unit is not pumped out;
• at a time when, according to the program, the device must drain, it stops;
• the dishwasher hangs with the error “I 20” when the washing program starts.

If these signs are present in the AEG firm, it will be necessary to check pump engine multimeter. The following is required:

• first of all, according to safety, you need to de-energize the device and cut off the water supply;
• remove the bulk and drainage hose;
• lay a rag on the floor and pull the car onto it;
• put the unit on the back and remove the pallet.

After removing the pallet, it is not difficult to find the pump: it connects the pipes and hoses. Remove all wires from the pump contacts and touch them with the test leads. multimeter. If measurements show an open or short circuit in the winding, the pump will have to be replaced.

Neff

Frequent triggering of the leakage protection system is the main disease of the ASM company NEFF (Neff). But in this breakdown there is nothing serious, and you will not have to call the master. How is the NEFF dishwasher being repaired? First you need to understand how protection works. Washing chamber has big floatlocated at its bottom. When liquid enters the pan, it raises the float, the sensor triggers, after which the unit stops working. This is how proper protection works.

But when dirt or food remains under the float mechanism, the float can rise due to this and include protection. Repairing NEFF dishwashers in this situation is very simple:

• using the on / off button, turn off the unit;
• after opening the chamber door, grab the float cover - you should raise and lower it several times, and all dirt and food residue can be removed with a cotton swab;
• You can turn on the unit and make a test of work.

Whirlpool

Failure of the internal valve is the most frequent breakdown in the Whirlpool machines. Before you start repairing Whirlpool dishwashers, you need to make sure that it is the fault of this valve (mechanic or electrician) that has failed. In case of malfunction electric part valve will have to be replaced.If the reason is in mechanics, then it can be eliminated with your own hands. To repair the dishwasher, you will need:

• disconnect the power supply to the unit;
• remove the front panel, which is under the door;
• on the left, in front of the device, you can see the valve itself, to which the hose is connected;
• Connect the ohmmeter probes to the contacts of the part, after disconnecting the wires.

Before starting the measurement, set the resistance value to the minimum. If during the measurement the tester shows from 500 to 1500 Ohm, it will mean that electric coil OK. If the values ​​are underestimated or overestimated - the coil has become unusable.

With a good electrician, the malfunction is caused by the fact that the valve may become clogged with lime. For this, the body of the Virpoolpool machine is unwound, and the mechanism is cleaned.

Ariston

Ariston is a fairly well-known and popular brand. But despite this, the PMM of this manufacturer also has typical breakdowns. If we eliminate the clogging of filters and mechanisms in the dishwasher, then most often the repair of the Ariston or Siemens dishwashers is made due to the fact that the heating element burns out, or the terminal block burns. In the image below it is circled in red.

It burns for the reason that during the work of the water heating program one circuit or two can be switched on. And the entire burden falls on this part. Change it does not work, and you have to buy new heater, even if the old is OK. This part must have the same marking as on the original part.

Repair Ariston dishwashers to replace the heater does not cause difficulties, and can be carried out personally. But after installing the element, you first need, without closing the housing of the Hotpoint-Ariston unit, to start the quick wash program. This is done in order to check the connections for water flow into the dishwasher, since the element is flow-through. If necessary, tighten the clamps as hard as possible.

For other faults in the nodes of the Hotpoint-Ariston dishwasher, repairs should be carried out by the master.

Smeg

Frequent reasons for the need for technical repair of Smeg dishwashers (Smeg) are broken heating elements, temperature sensors, drying fans or control modules.

How to disassemble the dishwasher and change the heaters in the dishwasher, it was said above.Well, what if your PMM has a function turbosushkibut at the same time the ware remains wet? This fact may mean that the fan forcing hot air has failed.

Repair and replacement of the fan, as well as the temperature sensor of the dishwasher, must be made the master from the service center. Independent repair of Smeg dishwashers and other brands (including repair of washing units) in case of failure of the control module is impossible. This should be handled by a qualified master, since only he will be able to determine the malfunction of the module and, if necessary, repair or reflash it. This specialist recruitment rule should also be followed when repairing professional dishwashers is required.

Candy

Most often, the Candy dishwashers are repaired due to improper handling of appliances (regular cleaning of the filters is required when servicing the dishwasher). When the drain system is clogged, the pump operates with a hung load and often fails. Also users complain about leakage from under the door while the Candy machine is running. It happens, according to reviews, after one year of operation of the machine.Eliminates the trouble of replacing the sealing element.

Zanussi

Repairing Zanussi dishwashers is most often due to fluid leaks. The models of machines in which the Aquastop protection system is installed show an error with the code i30 on the display. But it happens that there are no errors, but the water still appears from under the unit. The reason may be:

• the appearance of cracks in the tank;
• drainage hose leakage;
• loosening clamps;
• may jam the supply valve in the open state.

For tank replacement You will need to contact a master specializing in repairing dishwashers, since you have to disassemble the unit completely. Repairing dishwashers with their own hands, in such cases causes great difficulties. This breakdown is also common in the repair of Indesit dishwashers.

Replace the clamps and hoses can be on their own. To change the hose, you need:

• disconnect the device;
• shut off the water;
• disconnect the drain hose from the sewer and machine;
• do everything in reverse order with the new hose.

In the place of the entrance to the washer of the inlet hose is inlet valve. If, when checking with an ohmmeter, the tester shows that there is no resistance, it will be necessary to replace the part with a new one.

It should be noted that the repair of professional dishwashers Zanussi, Ariston, Kandy and others, should be carried out only with the assistance of specialists from service centers.

You can get rid of the majority of the above breakdowns characteristic of PMM from different manufacturers without the help of a wizard. But the main thing is not to overestimate your capabilities and take on repairs that you can make.
