Major dishwasher malfunctions

So, one day you found that the dishwasher does not turn on, does not drain or leak. Do not rush to immediately call the master, because sometimes the cause of the breakdown can be easily eliminated with their own hands without special skills and tools. Next, we will consider possible malfunctions of dishwashers and instructions on their self-repair at home.

What could cause a failure?

If the equipment has served you more than 5 years, and its warranty has long expired, it means that the possible cause of the malfunction may be banal wear of spare parts.

In the event that you have just made a purchase and the dishwasher has already failed, the causes of the breakdown may be as follows:

Poor assembly and parts themselves. It is found in cheap Chinese models from poorly known manufacturers.

Before loading the dishes into the camera, you do not wash away the leftovers of food that clog the filter. Very dirty plates most of the dishwashers are not washed completely, as a result of which it is necessary to polish additionally by hand.
The socket malfunction. It’s a banal situation, but it does sometimes occur.

Incorrect connection of the dishwasher (for example, the length of the drain hose is more than the allowable value or the hose with cold water is poorly fixed).
A bad detergent that doesn’t wash well or doesn’t wash dishes at all.

You may just have closed the door loosely (the mechanism is designed so that the appliances do not turn on until the latch works). It should also be noted that some models do not have the door fixed in the lower position. If the door does not hold it is not a breakdown of the dishwasher, but a flaw of the manufacturer.

Another fairly popular cause of the malfunction is the incorrect loading of dishes, as a result of which the technique poorly washes the lower department or top shelf. Even the instructions are the correct loading – the top should be filled with plates and mugs, the bottom – the size of kitchen utensils (for example, pots). Another important requirement is that glasses and cups should be stacked upside down.

If not one of these reasons is not the culprit of the failure, then it is about the parts, which we will talk about further.

Fixing major types of problems

The washing up process does not start
This situation: You have turned on a certain mode, all the indicators caught fire, the sound of filling water can be heard from the camera, it is heated, but the washing process does not take place. In this case, the probable causes of the dishwasher failure may be:

Clogging the filter at the bottom of the dive chamber. It should be obtained as it should be washed and set back.
Where the filter is installed
Filter

Clogging the injectors, causing the dishwasher not to spray water or it is simply poorly sprayed. In this case, take a toothpick and punch holes. Also clogging the injectors can cause low pressure during the washing process, as a result of which the pans are not laundered.

Running ahead I would like to say at once that if the rocker does not spin, the first thing you need to check the circulation pump, which often fails.

The failure of the circulation pump, the purpose of which is to supply water to the injectors. The most difficult breakdown of all three, as a result of which the dishwasher does not collect water.

All you need to do is replace the pump with a new one. To do this, we open access to it (located at the bottom of the camera), unscrew all the tubes and attachments to the body of the equipment, and then install a working pump. Circulation pump It is possible to determine the failure of the circulation pump by the characteristic sound of its work. If there is no noise after filling the water, it is most likely the cause of the malfunction in it! As you can see, the replacement is not complicated.

Water shimmers

Most likely, the water level sensor broke down. It is at the bottom of the technique, so for access you will need to turn the dishwasher, and then to replace the sensor with a new one.

Please note that if the power is cut off and water is poured into the chamber, then it is not in the sensor, but in the electromagnetic valve, which should block the flow of liquid. Replacing the valve is not a problem.

Overheating/water underheating

There is also a case that the dishwasher overheats or vice versa does not warm the water. In the first case, the temperature sensor breaks down, which entails overheating of water, formation of a large amount of steam and a shutdown of the equipment.

As for underheating, there may be several causes of the malfunction:

Again, the temperature sensor stopped working;
weak water pressure (in particular, a pump or nozzle);
TEN does not work (you need to check the resistance of the ER with a multimeter).

There is no drain

If the water does not drain into the sewer after the washing is over, the pump may be broken or the drainage system is clogged, so that the dishwasher does not drain the water.

As for the first case, it is necessary to check the drain pump for the presence of garbage and resistance of windings. Most likely, the water is in the dishwasher because of the fact that just clogged the pump, although sometimes the launch may not occur even because of the pressure. If the pump is fine, check the entire drain system, including the siphon. Most likely, the hose, which just needs to be cleaned, or the filter inside the camera, is clogged.

There is another frequent case when the dishwasher does not completely drain the water. Here you are likely to have too much drained the drain hose and after draining (when the pump shuts down), some of the water goes back to the chamber.

The body is electrocuted

If the dishwasher electrocuted, then with a probability of 99% it can be argued that the heating element – TEN – is broken. All you need to do is open access to the CHP and visually examine it for cracks and other defects. If the heating element is really damaged, replace it with a new one.

The reason that TEN fails is poor water quality (too hard). Another malfunction may also be the failure of the CHP relay. The instructions for replacing the details were clearly demonstrated in the video:

Doesn’t take detergent

If you notice that the dishwasher does not take the powder or tablet, most likely the cause of the breakdown is contamination of the injectors or weak water pressure, as a result of which it does not enter the dispenser. Also likely cause may be a failure of the valve opening mechanism from which the detergent is washed out. If the valve does not open the water intake (or closes badly), the tablet may not dissolve completely, as a result of which the technique poorly washes the dishes.

Lack of nutrition

If you notice that the time indicator is not even on fire or the technician does not react to the click of a button, the causes of the dishwasher malfunction may be as follows:

Broken socket;
The latch of the door did not work, or the locking device burned;
The network button doesn’t work.
The network filter doesn’t work.
In all cases, you need to use a multimeter to check all the elements of the electrical circuit and the method of exclusion to find out why the dishwasher is not turned on. If in your case the dishwasher does not end the cycle or you can not switch the program – check the programr and control unit, most likely the modes do not work because of its malfunction.

Foreign noise

Foreign noise indicates that the bearings of the pump or electric motor (supercharger) have been damaged. The bearings break because they get water, which in turn seeps through the damaged sledgeham over. Bottom line – the dishwasher buzzes at work. In this case, you will need not only to replace the bearing, but also the sledgeham over, otherwise after a while again there will be the same problem. By the way, the pump may be associated with another reason for foreign noise – debris got into the area of the sprinkler or working wheel. Here everything is simple, remove the garbage and check the wing for defects (perhaps already damaged blades, which causes noise).

The dishes don’t dry

Some modern models are equipped with the function of drying washed dishes. This process occurs when the fan installed inside the camera works. If you find that the dishwasher does not dry dishes (or does not dry), but otherwise functions normally, most likely the fan broke. All you need to do is check its winding, as well as suggestive contacts with a multimeter and if you need to, replace the part with a new one. We talked about how to use the multimeter in the relevant article.

Water leaks on the floor

And the last, one of the most popular breakdowns of the dishwasher – the flow of water on the floor under the body.

There are four main causes of leaks:

Door seals are in poor condition, causing the door to close open. They should either be changed or, if possible, cleaned from plaque.

The pump seal, which pumps water, is damaged. It is best to replace it with a new one.

Poorly tightened clamps on the drain and water hose, resulting in a leak. Seals may also not be installed at the junction sites.

The water tank on the side of the equipment was damaged. Most often the tank can not be repaired, so it is changed for the whole.

To correctly determine the place of water leakage it is recommended to remove the casing of the technique and put on the floor sheets of the newspaper. Where the newspaper will get wet and there will be a breakdown.

That’s all the major malfunctions of dishwashers. We hope that now you will be able to repair the equipment, if it stops working, starts making noise or will not drain water after washing dishes.
