Check and replacement of the press service in the dishwasher

All dishwashers are mandatory equipped with such a device as a water level sensor that is still referred to as the press space. Thanks to its installation, the boiler unit determines the automatic fluid level, the device is easily adjustable for subsequent washing dishes.

As long as the dishwasher works normally interference in its functions, it is not required, this refers to modern model.Electrolux models and others. If the device for washing the kitchen utensils began to gain excessive water or the dishwasher does not gain water at all, what is needed for high-quality washing, initially check whether the press service should be checked. In the event that the device gives failures when operating, other nodes of the device are incorrectly started, then you should contact the services of professional masters.

In the event that the device gives failures when operating, other nodes of the device are incorrectly started, then you should contact the services of professional masters.

Types of sensors

2 types of pressostats are installed on the machines:

Mechanical type devices. In case of appearance on the steamer, the relay of small holes have every reason to assume that a similar element can pass liquid. But if this happens when you are heard characteristic of switching modes, clicks, problems will not appear. If such clicking sounds do not hear, the relay should be checked on the imposition of contact groups.

Electronic sensors. Produce switching modes through an electronic structure operating under low voltage conditions. Checking the functionality of the working electronic board cannot be performed using instruments having a high voltage. If the device fails, the dishwasher will notify the error code.

In any case, when a malfunction appears, regardless of the type of item, the repair or replacement it must be done as soon as possible.

How to learn about breakdown?

The main function of this device installed in the Bosch dishwasher is the permanent monitoring of the required level of fluid. In the case when the device begins to work incorrectly, it means that the worker tank of the unit probably redested out, which will lead to a poor quality sink of kitchen utensils and flooding

In order to avoid such problems, it is necessary to closely monitor the fluid level in the working tank. If you notice that it exceeds the norm, this signals the failure of the pressostat.

Usually breakdowns of the water sensor in any dishwasher occur for the following reasons:

  • Wear to the details of the device.
  • Contacts for compounds of the device underwent oxidation.
  • Low quality dishwasher nodes, which limits the service life of the press.

How to replace the device in the unit?

Before starting the process of replacing this device, it is necessary to consider that each separate dishwasher brand is installed its unique device. This means that when choosing a new item, you must carefully read it with its parameters for the proper selection of the part. After purchasing the desired device, it should be replaced.

  • Initially carefully removed the rear wall of the machine.
  • After the level sensor is dismantled by the compound hose.
  • The part is removed from its location, the connector is also removed to connect.
  • The design is collected in reverse order.

After installing the new part, it is necessary to check whether the installation is carried out correctly, for which you need to start the unit. With proper assembly, the level of fluid in the working chamber should be optimal.

Operating safety and high-quality sink can only provide a good device, so it should be checked for health. In any case, the best to warn its way out of ordering than to continue to waste time and cash on its replacement. Therefore, be sure to follow the rules of operation of the dishwasher and clean the plums from the ground and 2-3 times a month.

The dishwasher aggregate greatly facilitated the work of the hostess having lost it from daily washing dishes. Downloading dirty dishes into the car and running it you can give time to other things, and the kitchen utensils, meanwhile, will be high quality and dried. But sooner or later, the indicator flashes on the table of the machine, which draws the attention of the user to breakdown or failure of parts.

Most frequent reasons

High quality and cost dishwashers are flagged by flashing indicator when filter cast. Similar troubles usually happens if the hostess does not clean up the kitchen utensils in front of the bookmark to the tank from food residues. By passing some time, the remains of food clog the filter element. As soon as the filter is filled immediately, the water supply indicator flashes.

Also, disorders during the operation of the dishwasher may occur due to the following reasons:

  • Malfunction of power supply socket.
  • Loosely covered door transmitting liquid.
  • Uneven and illiterate bookmark dishes in the tank.

But there are cases when none of these reasons approaches a specific situation, when the crane indicator is blinking, other reasons to which may include:

Frigidare, Electrolux Dishwasher. Pressure switch error. Diagnostic & Repair

  • The failure of the plumbing hose connected to the dishwasher unit.
  • Pollution of the filter element of the fluid release valve.
  • Defects input valve.
  • Incorrect connection of the drain hose.
  • Unauthorized activation of the function “Aqua-Stop”.

There are several other disadvantages in which the indicator flashes on the control display occurs. If it is impossible to independently detecting and solving the problem, the best way out of the situation will call the wizard for the repair of this equipment.

Modern dishwashers have not only standard programs, but also additional functions to which the automated sink of kitchen utensils also includes, thanks to the “Aqua sensor” mounted.

All about water level sensor in dishwasher

Each dishwasher is equipped with such a detail as a water level sensor, also called the press service. It is due to its presence, the equipment will be able to determine the water level in automatic mode, as well as adjust it with further washing of dishes.

While the dishwasher aggregate performs its main purpose, the hostess can be engaged in its usual affairs. This applies to all modern models. Bosch, Electrolux, Zanussi, Ariston, Beko. That is why if the water level sensor gives malfunctions, then all the equipment begins incorrectly. In such a situation, without professional repair, it will not be possible to do.

What could be the sensors?

In the case where the dishwasher has gained more water than it is required for high-quality car wash, it is primarily to check the water level sensor.

Two main types of such sensors (pressostats) differ:

  • Mechanical type devices. If small holes began to appear on the membrane, then you can suspect that such a sensor passes water. But if the further operation of the dishwasher is accompanied by characteristic to switch clicks, problems will not. But in the absence of any clicks, you need to carefully check the relay for sticking the contacts inside it.
  • Electronic sensors, as well as mechanical type devices, have hoses and tank in their design, but there are no such elements as a switch and relays, there are no. Switching via electronic board. Since electronic sensors perform their work in low voltage conditions, then check their operation with high voltage devices will simply fail. If this element of the dishwasher, shown in the photo, fails, then the device will notify the error code.

How to remove the sensor breakdown?

The main task of the pressostat of the dishwasher is to control the water level in the device. And if such a detail gives failures, then there is a high probability that the working chamber will redirect. It can lead to poor cleaning of dishes and even flooding.

In order to accurately determine the breakage of the water level sensor, it should be very careful to trace the water located in the working chamber. If its number will be much varied with the norm, it is possible to accurately say that it was the press service.

The sensor breakdown may occur as a result of the following reasons:

  • wear of this element of the equipment;
  • The connecting contacts of the sensor were oxidized;
  • The nodes are generally have low quality, which leads to short exploitation terms of the press.

How to replace the sensor in the dishwasher?

Before the procedure for replacing the water level sensor, you should know that each dishwasher model is equipped with its unique detail. That is why the choice of the new press costs should be considered with all the responsibility. As soon as the desired spare part is chosen, you can proceed to the direct replacement of the sensor.

This procedure is performed as follows:

  • To begin with, it will be necessary to very carefully take the back panel on the dishwasher.
  • Next, under the press, the connecting hose is removed.
  • The node is disconnected from its landing place.
  • Connector for connection is also drawn.
  • Build a new sensor is carried out in reverse order.

Once the new item will be installed, it is necessary to check the correctness of its installation by means of the test launch of the dishwasher. If everything is done correctly, the water level in the unit will be optimal.

To replace either the repair of the water level sensor, you need to stock up with a divorce or wrench, as well as a screwdriver.

Only a working water level sensor can guarantee the quality and safety of the dishwasher. That is why from time to time it is worth controlling its health.

Basic dishwasher

If you want to know how the dishwasher Indesit. Bosch, Electrolux or dishwasher from any other brand, be sure to read the material to the end. Let’s start with the most important thing from the heart of the device. It is a powerful engine, sometimes referred to as a circulation pump

He chases water in a circle with a detergent or a rinse, taking it from the working chamber and returning through the rocker. As for the rocker, they serve as rotating splashing nozzles.

The largest element in the dishwasher device is a working chamber. It is in it there are rockers playing the role of detergent elements. Also here are the baskets where the dishes are laid. Baskets can be adjusted in height, and some manufacturers endow them with a transforming design, which facilitates the bookmark of the kitchen utensils of non-standard sizes.

  • Filter. ensures filtering and removal of solid contaminants (food residues);
  • Drain pump (it is a drainage pump). removes dirty water outside the dishwasher;
  • Drain hose. his purpose is understandable without any Комментарии и мнения владельцев;
  • Aquastop. it is not present in all dishwashers, but allows you to protect yourself from leaks. The executive element of this node is the electromagnetic valve, located at the very end of the bulk hose.

Also in the device of any dishwasher there is a next bunch:

  • The bulk hose. it connects to the water supply, through it in the apparatus it enters cold water (or hot, if someone has connected the technique to the hot water pipe);
  • The electromagnetic valve. participates in water, overlapping or opening it;
  • Water heater. classic or flow. The latter helps to reduce the duration of the cycles, heating the water instantly, and not gradually.

Note that before the bulk hose is a simple coarse filter in the form of a metal mesh. It plays an important role in the household dishwasher device, sielding large contaminants that can get into the dishwasher from a tap pipe. As we see, the dishwasher is extremely difficult

And all this despite the fact that we have not yet affected a number of important bodies, nodes and systems. Ion exchanger. a very important detail responsible for water softening. The fact is that salts dissolved in rigid water impede a normal wash. The exchanger operating on the basis of a special ion exchange resin allows replacement of magnesium and calcium ions to sodium ions, resulting in water becomes softer

As we see, the dishwasher is extremely difficult. And all this despite the fact that we have not yet affected a number of important bodies, nodes and systems. Ion exchanger. a very important detail responsible for water softening

The fact is that salts dissolved in rigid water impede a normal wash. The exchanger operating on the basis of a special ion exchange resin allows replacement of magnesium and calcium ions to sodium ions, resulting in water becomes softer.

In a bundle with an ion exchanger, a container is installed in which the salt or substance replaces the salt. they help restore the number of sodium ions in ion exchange resins. Salt from here is closed in automatic mode, its number depends on the settings displayed in the dishwasher. Approximately 1 kg of special salt for dishwashers.

In addition, in dishwashers there are pressostats (water level sensors), thermostats (determine the temperature of the washing mixture), various sensory sensors (in automatic machines). Also here are installed water collectors for collecting water, there are numerous connecting hoses and clamps. All this is the case in the case with efficient noise insulation.

We forgot to mention the most important part in the internal device of any dishwasher. this is a control board that is a “brain” for all the filling. It is from her that the wires to the sensors and various electrical modules are diverged. In the bundle with the board runs the control module on which the handles, buttons, indicators and other elements are located

In the bundle with the board runs the control module on which the handles, buttons, indicators and other elements are located.

In old dishwashers, there were mechanical control modules. In modern technique, they are not used. their device is based on electronics.

As for detergents and rinses, they are loaded into special dispensers. most often they are located in the boot doors. This also contains tableted preparations of “all in one” format, containing all the necessary chemistry.

Pressostat function in a washing machine

Feature of constructive design Machine for washing dishes. use of the optimal amount of water at high purification efficiency.

Actually, this factor is an obvious moment, since the degree of cleaning of kitchen utensils dishwashers depends not as much on the amount of water, how much of its temperature and spray technology.

The functionality of the dishwasher has its own design features, due to which a relatively small volume of water is carried out washing a rather large set of kitchenware

On the contrary, if the unit uses too much water, due to the increased hydraulic resistance, the splashing function is disturbed, and high power and time costs will be required for heating.

That is why an important component of the structure is the water level sensor. The presence of this device allows you to control and maintain the exact water level in the car

The quality of the sink process largely depends on the quality of the incoming water. If it contains a high percentage of suspended substances, rapid wear of various design details is guaranteed

Meanwhile, the correct and impeccable work of the machine is noted, as a rule, on the initial period of operation of the equipment.

Then, at some point in the use of the equipment, the owner of the dishwasher begins to notice the failures in its work. The root cause of failures is usually the press service. And the point here is not at all in his quality.

One of the possible design options for the press machine for washing dishes. Fully plastic case and only contact group of switch and several mounting screws. metal

The quality of water is played in this process, which is used to feed the dishwasher. Unfortunately, in most cases of operation, the high quality of the water of the centralized water supply is not to speak.

And low-quality tap water pretty quickly displays plumbing of any kind. Playing Machine Press Contuffs.

Signs of pressure relay malfunction

When the item fails, the control module “does not know” how much water is already scored in the chamber and when it time to stop the fence. Therefore, it can happen:

  • Pereliv. Liquids in the bunker more than need. The problem threatens to turn into a flood, so it’s not worth the repair with repair.
  • Non-Foam. The lack of water in the system can lead to the heater brave.
  • There is a fence and at the same time draining water.
  • Technique does not take fluid or stops in the middle of a cycle with a full tank.

All these features indicate the Press Transport Malfunction. And what causes the breakdown:

Whether the sensor setup is possible if his testimony has come down? Yes, it is possible to make in the factory. The bolts on the relay housing are tightened to a certain level to adjust the indicators.

Most frequent reasons

High quality and cost dishwashers are flagged by flashing indicator when filter cast. Similar troubles usually happens if the hostess does not clean up the kitchen utensils in front of the bookmark to the tank from food residues. By passing some time, the remains of food clog the filter element. As soon as the filter is filled immediately, the water supply indicator flashes.

To understand the device of the dishwasher, familiarize yourself with the main nodes of dishwashers Figure 1, their purpose and principle of action.

Consider details the device and the principle of operation of the dishwasher:

The device of dishwashers, regardless of the manufacturer and its model, can be represented by a single scheme Fig. 1. The main functions that the dishwasher performs after pressing the Start and Closing Button, this is:

  • Drain of water (usually when starting any selected program).
  • Bay of water.
  • Beginning of the process of washing.
  • Adding detergent (laid at the download stage of the dishes).
  • Heating of water.
  • The sink process (takes time depending on the sink program you chose).
  • Draining.
  • Bay of water for rinsing.
  • Rinsing.
  • Draining.
  • Drying.

Eleven basic functions are responsible for quality cleaning of dishes. Eleven basic functions perform function nodes (parts, devices, peripheral devices) dishwashers. The sequence of turning on / off peripheral devices of the dishwasher monitors the electronic control module (hereinafter referred to as the processor) similar to those depicted in Fig. 0.

Washing program. sequence of instructions performed by the processor. Washing programs are distinguished by:

  • time (time spent).
  • The degree of water heating (from 50 ° C to 75 ° C).
  • presence or absence of pre-soaking function.

Consider the main nodes of dishwashers and their functional purpose on the example of a phased implementation of the washing program from the start to its full completion.

You have chosen the washing program, laid the detergent, added the rinser (optional), press the start button (Start) and slammed the dishwasher door. What happens next?

The processor checks the door closure and gives the “Rinse after the previous washing operation”:

For the closure of the door corresponds to the lock Fig 2 (in Figure 1, see number 15). If the door is correctly closed, the castle closes the contacts. This is the signal processor “door closed”. Having received the signal “The door is closed”, the processor submits the command to the drain pump 3, (in Figure 1, see numbers 8) “Dry water“. The drain pump begins to perform its function.
