Reasons and what to do if the water does not come out of the dishwasher
Quite often a situation arises when the water does not leave the dishwasher. To establish the causes of this breakdown, it is necessary to diagnose. Some violations can be eliminated on their own, while others require professional help. A common cause of standing water is a clogged or kinked drain pipe. Also, failure of pump or control system is called provoking factor.
How the dishwasher works
Dishwashers are equipped with an inlet valve through which clean tap water is pumped. After filling a special tank, the liquid is heated or supplied to the rocker arms by means of an electric pump.The jets are directed at different angles, which makes it possible to obtain a quality wash. The water then enters the bottom of the compartment, where it is filtered by 2 types of filters. After that, the prepared liquid accumulates in a special container.
Water that the system perceives as unsuitable for further use ends up in the drain. This is ensured by a drain pump.The cycle of the device is monitored by a special device - a pressure switch. If necessary, the heating element heats the water to the required temperature. A solenoid valve is responsible for supplying the process with detergents. If any part of the appliance fails, water can accumulate in the dishwasher.
First steps
The reasons for the stagnation of liquid in the dishwasher are different. Draining the water is considered the final step in the dishwashing process. If the contaminated water cannot be drained, the machine will not be able to start the next washing phase. In some types of appliances, it is not possible to identify the water drainage problem until the end of the washing process. Only after completing the wash and opening the lid will it be possible to see the accumulation of water in the device. As a result, the dishes are not clean enough.
To eliminate the breakdown, it is recommended to identify the exact reasons for the lack of fluid drainage. These include in particular the following:
- violation of the location of the drain pipe;
- pressure switch failure;
- accumulation of a large amount of debris in the coarse filter;
- contamination of other elements of the unit drainage system;
- control unit fault.
What malfunctions can be eliminated on your own
To repair a breakdown, you need to know which defects can be eliminated with your own hands, and which require professional help.
Clogged primary filter
If the unit does not drain, it is recommended to assess the condition of the primary filter. It is located in the tank of the device - in the center of the lower part. The device opens easily. It's quite easy to reach it.The filter can be removed by simply unscrewing it. The filter should be removed and thoroughly washed. If necessary, it is recommended to also rinse its base. It is recommended to remove stagnant dirt from it.
It is not recommended to skip the preparatory stage before washing dishes. Usually, before placing the appliances in the dishwasher, they must be cleaned under running cold water. This will help remove large debris and other blockages. This prevents clogging of the filter.
If the drain hose is kinked or clogged
A kinked or dirty drain hose is a common cause of problems. In this case, water does not flow from the device.
To solve problems, it is worth changing the position of the hose, turning on the device and trying to restart it.
Clogged drainage system
If you can't drain the water, you should suspect a clogged drain. Food scraps often cause clogs to form in the drain pipe and the areas where it goes down the drain. It is quite possible to clean these fragments yourself. First, the drain hose must be carefully disconnected from the sewage system and lowered into a prepared container. Then it is worth starting the drain function. If the liquid flows out in large quantities, you can suspect a problem with the attachment of the pipe and the sewer. If the unit does not completely drain the water, it will not be possible to avoid cleaning the pipe.
Contamination of other parts of the drainage system
Cleaning the filter does not always lead to the desired effect. In such a situation, it remains to look for a clog in the rest of the drain system. If, after disconnecting the pipe from the siphon, the water drains freely, then the plug is located in the sewer inlet area.In this situation, ordinary cleaning is sufficient.
It is much more difficult to remove contamination from the pump. To clean this part, it is necessary to determine the most practical way to drain water from a turned off unit. It is allowed to do this by gravity, tilting the device to the side, or to drain the water manually.
After that, it is recommended to perform the following actions:
- remove the pipe;
- place the device on its side;
- remove the pallet;
- remove the level control sensor;
- remove the pump, access the contacts and fixing elements;
- clean volute and impeller;
- clean the contacts and measure the resistance - normally it should be 200 ohms;
- assess the operation of the pump valve for the presence of contamination.
In which cases it is worth contacting specialists
It is not always possible to eliminate faults in the dishwasher yourself. Sometimes you have to turn to the professionals.
Accumulation of debris or broken drain pump
If the drain pump breaks down, only replacing the damaged part with a new one will help fix the breakdown. This defect is considered one of the most common causes of drainage problems. If the dishwasher device allows easy access to this element, you can try to replace it yourself. To do this, it is recommended to disassemble the part, clean it well and assess the ease of rotation of the wheel.
This procedure is performed with a pencil or other elongated object. It should be kept in mind that blockages usually include shards of dishes and other sharp objects that can lead to injuries.
Pressure switch malfunction
If this element fails in the dishwasher, the program module does not receive information about the internal water pressure.In this case, it is worth replacing the broken part. Otherwise, the device will not work properly. As a result, the risk of flooding increases significantly.
Broken software module
This dishwasher element analyzes the washing cycles and sends the necessary signals to the other parts of the appliance. If the system breaks down, the dishwasher will not work properly. If the unit does not completely drain the water, it is often possible to suspect a software module failure.
Rules of maintenance and operation
Dishwasher failures are caused by improper use of the product. As a result, filters, pipes and pipes clog. Leaks often occur when seals become greasy.
To avoid the appearance of problems, it is necessary to follow the rules of prevention:
- Leave the door open after the dishwashing process has finished. Due to this, the liquid evaporates faster. This will help prevent mold growth.
- It is recommended to wipe the door sealing rubber with a dry sponge.
- It is recommended to clean the exterior of the dishwasher with a damp cloth.
Every 1-2 weeks it is worth doing the following:
- clean sprinklers;
- clean the drain and intake filters;
- inspect and clean pipes;
- clean the interior fragment of the bunker;
- wash the compartment for the detergent composition.
It is recommended to use only special formulations for the device. These include tablets, gels and powders. It is imperative to use a rinsing product.
For the correct operation of the device, it is worth using special detergents. Pour salt into the dishwasher.Today there are many options for such a tool on sale. It softens the water, removes impurities and reduces the risk of scale.
In order for the dishwasher to work as long as possible, you must follow these rules:
- it is good to clean the dishes from food;
- respect the order of the loading devices;
- do not overload the device.
If the water does not come out of the dishwasher, it is recommended to carry out a thorough diagnosis. Thanks to this, it will be possible to identify the causes of problems and select an effective repair method.
