Potential dishwasher breakdowns

When the dishwasher has been operating for more than five years, and the warranty periods have long expired, any worn part can cause equipment breakdown. But what to do when the equipment was acquired relatively recently? If the purchase of a household dishwasher is still fresh, the malfunction factors may be as follows:

1. The equipment was poorly assembled or the condition of some parts was already malfunctioning. Often this happens with cheap Chinese manufacturers with little known reputation.
2. On the dishes that are loaded inside the machine, there is a lot of uncleaned food. As a result, filters get clogged. When the dishes are very dirty, the machine often fails, which makes it necessary to rinse the dishes with their own hands.
3. The power outlet for the machine does not work. A fairly common cause of the malfunction.
4. Often, repairs to dishwashers are caused initially by the improper connection of water lines: the drain hose is of an unacceptable length or the hose has been loosely fixed with cold water.
5. An unreliable dishwashing detergent is used. As a result, dishes are poorly washed away from fat or even remain dirty.
6. If the appliance does not turn on, the door may not have closed properly. The machine starts only when the door is tightly closed until a distinctive click is heard. When the door does not close properly even when the latch is activated, such malfunctions are attributed to the manufacturers of this type of kitchen equipment.
7. A malfunction of the dishwasher is caused by improper loading of the dishes. In this case, the quality of washing the cutlery in the upper section and the pots on the lower shelf will deteriorate significantly.The operating rules of the technique provide recommendations for the competent loading of dishes and cutlery: the upper section is filled mainly with cups and plates, the lower - with pots. It must be clarified that cups and glasses should be stacked with the bottom up.

When these factors do not underlie the malfunction of the machine, it is most likely that the reason lies in the breakdown of specific parts.

Dishwasher does not wash dishes well

There is a possibility of the following problem: the machine is set in the desired mode of operation, each indicator is working properly, the sound of water moving is heard, the heating process is not standing, but the dishes are not washed. There are several reasons whythe dishwasher does not wash the dishes well.

Firstly, the filter located at the very bottom of the washing compartment is often clogged. In such a situation, the repair of dishwashers on their own will consist only in removing the filter and cleaning it.

Secondly, nozzle clogging occurs no less often. The result will be a slight spray of hot water or none at all. Such breakdowns adversely affect the water supply pressure inside the chamber. Therefore, the dishes will be poorly washed. In such situations, a regular toothpick rescues the nozzle openings. Also, the “shoulder” of the nozzle may not rotate. In this case, pay attention to the circulating pump. Its breakdown is also a frequent occurrence.

Thirdly, as already agreed, there is a breakdown of the circulating pump. Through it, water enters the nozzles. In this case, the repair of dishwashers on their own is somewhat more complicated due to the seriousness of the breakdown. For the adjustment of equipment will require a complete replacement of the defective part. To repair the dishwasher with your own hands, you must open access to the pump located at the bottom of the chamber, disconnect all available communications and fasteners from it. Then install the working part.

How to understand that the reason for the failure of equipment is in the pump? When the water is full and the machine is quiet, it is most likely that the pump is malfunctioning.

Water overflow

Such a breakdown is caused by a malfunction of the water level sensor (pressure switch). It is located at the bottom of the machine. You will need to deploy a dishwasher to get to the water level sensor. Then you can easily replace with a working pressure switch. You should also be careful if the element is in the on mode and water enters the chamber unhindered, the electromagnetic valve is broken. It is he who must stop the flow of water if necessary. It is not difficult to replace the solenoid valve with your own hands.

Problems with heating water

When the dishwasher breaks down and does not heat or overheat water, it is recommended to pay attention to this. In case of overheating, the breakdown is in the temperature sensor, which is why the water overheats. As a result of this, there is an excess of steam and the dishwasher stops.

If the water does not heat up and remains cold or barely warm, there are several phatoria that can cause a similar phenomenon:

• faulty temperature sensor;
• low water pressure at the nozzles or pump;
• malfunction of the heater (it is necessary to verify its serviceability with a multimeter).

Dishwasher repair: drain does not work

When the dishwasher is working properly, but the waste water does not drain well or does not accumulate at all inside the washing compartment, the malfunction may be hidden in the drain communication pump and therefore there is no discharge.

To fix this problem with your own hands, you should conduct a detailed inspection of the pump for clogging and resistance of the winding. Stagnation of water in the machine can happen precisely because of clogging of the pump.When it is found that there is no debris in the pump, it is necessary to inspect the entire drainage communication, not excluding the siphon. Most likely, the drain channel could clog. In this case, you should simply remove all blocking elements.

Sometimesthe dishwasher does not drain the water, because the position of the drain hose in relation to the level of the machine is too high. After turning off the pump, part of the used water flows back into the washing compartment of the machine.

Voltage breaks through the body

When the dishwasher turns on and an electric current passes to the body of the equipment, it is most likely that the cause of the breakdown lies in the malfunction of the heating element. You can fix such a malfunction with your own hands if you carefully examine the heating element for surface damage. If any are found, the heating device should simply be replaced with a new one.

The cause of such damage is often too harsh properties of water. In addition, the heating heating element often breaks down when the starting relay does not turn on well.

Dishwasher does not pick up detergents

Frequent defects in the operation of such a technique is a poor intake of detergents, liquid or in the form of tablets. The reason for this can also be a weak water pressure or a malfunction of the nozzle, which leads to a weak water ingress into the dispenser. In addition, the mechanical valve that controls the washing out of the detergents is often broken. Due to the poor performance of the valve allowing water to pass through, the agent often remains closed for water access. Consequently, the dishwashing performance is reduced.

No power

When there is no indicator backlight or the dishwasher does not turn on when you press a button, you should check several options for breakdowns:

• malfunction of the outlet;
• the door has not closed completely, the automatic door lock does not work;
• network button works;
• breakdown of the mains filter.

In each of the proposed options, using a multimeter, it is necessary to check the entire electrical circuit for defects. Excluding serviceable elements, an idle part is detected.

Abnormal sounds of work

Extraneous noise may indicate a damaged motor or pump bearing. Damage to the bearing is caused by the penetration of moisture through worn oil seals. As a result of such violations, an unnatural sound for a dishwasher is generated. To fix such a defect with your own hands, you will need to replace both the bearing itself and the damaged oil seal. Otherwise, such a breakdown will happen again soon.

Dishwasher drying does not work

For many modern models of dishwashers, the function of drying clean dishes is characteristic. This process is carried out by a blower fan installed in the washing chamber. When the machine is working properly, but does not dry the washed dishes, the fan is probably defective. To fix such a breakdown with your own hands, you should carefully inspect the supply wires and the winding of this part. If necessary, replace the fan with a new one.

Water leaks to the floor

Another of the most common dishwasher breakdowns is case leakage. There is a possibility of one or more reasons:

1. The sealing tape, located around the perimeter of the door, was leaked. Density of closing is reduced. It is necessary to replace bad seals or clean them of plaque.
2. Also, the pump seal may be damaged. Then replacement of the seal is required.
3. Poor quality strengthening of drainage and water-injection communications. Leaks occur at the joints.
4. In the side of all dishwashers there is a storage tank for water. In some cases, it can leak. In such situations, it must be replaced, since it cannot be repaired.

For accurate detection of leakage, you must completely detach the dishwasher. Then under it you need to lay out clean sheets of paper. At the places of leakage, water droplets that have fallen on the paper will be visible.
