What if the dishwasher is clogged?

Problems with the discharge of waste water - the most common failure of the units for the care of dishes. When the dishwasher is clogged, you do not need to panic. This can happen for several reasons that are easy to diagnose on your own. Simple repair is also possible for any owner of a dishwasher. What to do and what actions should be taken in this unpleasant situation?

What is the cause of the malfunction?

There are several main reasons for obstructing drainage. This can be both mechanical malfunctions and violations in the operation of the control center.

Attention! Before conducting an initial inspection of the device, you must disconnect it from a direct power source, in accordance with the rules of safe operation.

Obstruction of the dishwasher can interfere with the smooth operation of the following units:

1. sewer system apartments
2. internal removable filter
3. drain pipe system
4. filter in the water supply valve
5. drain pump
6. lobed elements.

Before diagnosing, you need to make sure that there are no obstacles to the drainage of waste water due to excess dishwasher drain hose.

How to eliminate the causes yourself?

Each of the breakdown options has its own simple solutions, which you can try to cope on your own. Before starting repairs, you must carefully read the instructions for the machine, and unplug the power cord from the outlet. Then remove the drain hose from the sewer and lower it into a bucket. If the liquid suddenly poured in a sharp stream, then the most likely cause of clogging is a clogged sewer or drain. If the water still remains in the dishwasher, you need to look for the reason further, after collecting it manually and draining the internal tank.

Kink of a drain hose. During the general cleaning of the apartment and direct care of the unit itself, its location may temporarily change. Therefore, the drain hose can bend anywhere and prevent water from flowing freely. You need to carefully inspect it for proper installation and correct the situation.

Sometimes the hose gets clogged with mechanical debris (bones, solid food particles) and loses its throughput. Then you need to disconnect it from the dishwasher and remove from the connection to the sewer and rinse under high pressure.

Bad water pressure. If the pressure in the city water supply system is poor, then it will fall into the device in insufficient quantities and may cause a general malfunction of the electronic module. The wash cycle will start incorrectly and the order of commands may be incorrect.

Blocked sewage in the apartment. If the device has a common outlet with a sink and water does not drain well from there, then you should try to eliminate mechanical blockage with the help of special chemicals such as “Mole” or with a cable to clean the sewer system. Most often, the root cause of poor water drainage in such cases is pipes clogged with plugs from hair, frozen fat or food debris.

Clogged general sewer system in an apartment building or private house, it will also prevent direct outflow of water. To understand this is very simple - not only water from kitchen appliances does not drain, but, in general, everything in the house.

Drain filter clogged. Almost always, home appliance users neglect the manufacturers' recommendations for use. The appliance is not properly maintained and this leads to a malfunction.In the case of using a dishwasher, the manufacturer strongly recommends that you clean the cutlery from the pieces of food not eaten before laying. Otherwise, they strongly clog the fine mesh of the internal filter and prevent the waste fluid from draining. This problem is easy to handle. You just need to get the removable filter, clean it under running water and install it back.

Clogged blades most often due to the poor quality of city water. When it is very stiff, the shallow outlet openings become clogged with limescale and the flow of water gets into the wrong place. It is necessary to remove the blades, clean them with a toothpick, rinse under a strong stream and insert the impeller back.

Blockage of the drain pump. When the internal drain is clogged, water is in the internal tank and does not flow out through the drain hose. If all of the above measures do not help, then the reason may be in the drain pump. You can find its location by carefully studying the instructions. Unscrew the protective cover and try to rotate the pump blades with a stick or pencil. When the course is difficult, it is worth trying to remove a foreign object and screw the pump back.

Attention! In no case should you climb to the blades with your fingers. Typically, pieces of broken dishes become the cause of the pump to stop mechanically. Contact with them will lead to cut wounds to the hands.

Special cases

None of the measures taken help? What to do in this case? Call the master! Most likely, some control has failed. Only a qualified craftsman can identify such a breakdown and replace it with a new one.

Incorrect operation of the software module. When the electronic "brain" does not properly analyze the operation of the device and submits incorrect programs through the control module, the outflow of water may stop. It is possible to diagnose such a failure only with special devices. You can fix the breakdown by flashing and replacing the node with a new one. This is the most expensive type of repair work of the dishwasher and the risk of causing serious harm in self-repair is quite high. Checking the operation of the electronic unit is the prerogative of an employee of a specialized service center.

Water level sensor failure. The force of the water pressure inside the dishwasher is measured by a special device - a pressure switch. They are of two types - electronic and mechanical and do not make direct contact with water during operation. All measurements are carried out through a special air membrane and fed to the sensor. The cause of the failure of the assembly may be oxidation of contacts, puncture in the pressure switch tube, detergent or factory defect entering it. Failure is diagnosed using a multimeter, so calling a qualified craftsman is a necessity, not a fad.

Preventative measures

Any malfunction is cheaper to prevent rather than eliminate. Preventive measures - this is the very first and main way to save kitchen appliances from trouble in the form of breakage. With proper operation, according to the advice from the manufacturer, you can avoid many unexpected emergency situations. Compliance with simple rules will relieve headaches, spent nerves and money:

• regularly clean the strainer inside the main camera of the device.
• When loading dishes into the machine it is worth inspecting and periodically cleaning the blockages in the nozzles of the blades and the place of their attachment.
• Two or three times a year, it is worth checking, removing and cleaning the inlet and outlet filters on the supply and drain hoses with plain water.
• To clean dishes before loading the remnants of paper towels, labels and pieces of food.
• It is necessary to use a special emollient salt for hard city water to prevent the formation of limescale.
• Avoid getting excessive moisture and grease on the dishwasher control panel.

Worth remembering! Once a month, you need to rinse with a special anti-alkaline agent. As an alternative, people have long been using citric acid for these purposes. It is necessary to fill the powder into the detergent compartment and drive it “idle” at the highest temperature. This measure effectively eliminates solid fatty deposits inside the supply system - water drainage. It will also help to save the heater from scale and premature failure.

The best way to protect yourself from questions about how clogging in a dishwasher is eliminated is to handle it carefully and gently! Then it will last for many years without failures and serious repairs. With proper handling, it can seriously simplify the difficult life of housewives and save you from the daily exhausting washing of a lot of dirty dishes.

You do not need to save one-time on calling a specialist from a service center so as not to increase the material costs of repairs in the future.
