How to disassemble a dishwasher: step-by-step instructions. Electrolux dishwasher errors

Dishwashing units from Electrolux are a fairly common phenomenon in Russia. Despite the high quality of the components and assembly of the Electrolux dishwasher, it, like other units and devices, can break down and requires utmost attention and prevention. Before you begin repairs, you need to diagnose problems, identify typical ones and learn about existing repair methods. In this article we will try to tell you about how to repair Electrolux dishwashers and other subtleties associated with this process.

Electrolux dishwashers

The Swedish company Electrolux is deservedly considered one of the leaders in the household appliances market. Dishwashers with the company's brand name are in great demand due to their reliability, ease of use and stylish design.

The company does not stop working on improving dishwasher models, increasing their reliability, and developing innovative solutions.

An example of increased reliability is the use of the AquaControl function, which protects the machine from leaks and from overflowing with water. At her commands, the water supply is stopped and it is drained into the sewer.

In any case, even very reliable equipment wears out, which means failures occur. In addition, users do not always follow the manufacturer's recommendations, which also ends in failure.

To increase reliability and simplify repairs, dishwashers of this brand use a self-monitoring function. Even for an ordinary user, it is not particularly difficult to analyze the cause of a breakdown using error codes, which means quickly restoring the machine’s functionality.

When an error occurs, first of all, the machine reboots in this way: it is disconnected from the power supply for 15 minutes, and then turned on. If the error does not disappear after switching on, in all likelihood, you need to search for the problem using the codes.

Let's look at the main machine breakdowns

The majority of dishwashers supplied to the Russian market are produced in Poland and account for about 90%. The quality of their components and assembly can be compared with similar units from German and Swedish companies, but, as they say, you don’t have to choose. Most experts highlight the following advantages of household appliances manufactured by Electrolux:

all components are made exclusively from high-quality raw materials;
the development of circulation pumps was approached really wisely, they were designed with a high working life;
The manufacturer is meticulous about small details, such as wires, clamps, terminals, rubber bands and filters, which in turn increased the period of trouble-free operation of the dishwasher.

No particularly critical disadvantages were found when using the dishwasher; they, like everyone else, are characterized by typical breakdowns, from which it is quite difficult to protect yourself. Let's list them below:

clogging of drain and filler pipes;
failures in the water collection program;
problems with the quality of dishwashing;
The heating element (heating element) does not heat the water sufficiently.

Conclusion

All possible damage to Electrolux dishwashers can be divided into three categories of complexity:

The first category is minor repairs. Breakdowns are fixed by the users themselves. This includes cleaning clogged components, bending hoses, cleaning filters and other minor work,
second category - medium repair. This is a replacement of small parts (buttons, filters, pumps),
the third category is professional repair. This type of repair is used when it is necessary to carry out diagnostic work on electrical and electronic circuits, replace main parts, flash firmware and adjust electronic circuits.

Typical failures

According to statistics, 90% of cars under the Electrolux brand that are sold in Russia are manufactured in factories in Poland. Their quality is slightly worse than their counterparts from Germany, but the pricing policy is not bad either. Experts from service centers, especially for Russian consumers, note the following advantages:

reliability and quality of machine body;
well-equipped circulation pumps with a long working life;
During assembly, the main attention is paid to small parts - wiring terminals, rubber seals, filter elements, connecting wires and clamps, on which the trouble-free operation of the equipment primarily depends.

No particularly obvious shortcomings or weaknesses were found, but, like other brands, there are some typical breakdowns and malfunctions from which no one is immune:

hoses and pipes of water supply and drainage systems often become clogged;
The water does not heat up according to the mode;
Sometimes problems may arise with the execution of the specified dishwashing programs.

In order not to frequently repair your dishwasher, you must always pay attention to the condition of the equipment and adhere to the recommendations set out in the instructions.

If the capacitor is faulty

Voltage fluctuations in electricity and other negative factors can cause the fuse of an Electrolux machine or any other to break. Therefore, if the dishwasher does not turn on, and the socket, cord and water supply hose have been checked for serviceability, then it is necessary to check the condenser. If the fuse is blown, this is another reason why the dishwasher won't turn on.

To diagnose this important spare part, the machine will have to be disassembled, since the fuses are located under the pan. It is recommended to prepare a rag in advance, as stagnant water may spill out of the equipment. You will also need a multimeter to measure resistance.

Procedure:

remove the panel located in front, under the dishwasher door;
remove the side fastenings from the pallet;
open the door;
remove the filter and impeller;
close the door and turn the equipment over;
remove the pan;
We are looking for a fuse on the circular pump;
Using a multimeter we measure the resistance.

If no resistance is detected, then the capacitor has failed. You need to remove it and buy a similar one. According to the diagram, we put the new fuse in place. If even after these manipulations the dishwasher does not turn on, you should contact a technician for help.

Removing internal and external blockages

A clog may be the reason why your dishwasher does not turn on when you press the start button. A similar problem can be solved without the involvement of a repairman. There are such blockages inside and outside.

Problems with the heating element

If you notice that the water in the dishwasher is not heating up enough, then most likely there is a problem with the heating element, or with the temperature sensor or other control modules. Electrolux dishwashers are quite sensitive to voltage fluctuations, as well as to oversaturation. What could this lead to?

In the best case, you will get away with a blown fuse; in the worst case, several triacs on the control board may burn out. After this, the control module simply will not be able to send signals to the heating element, or will do so with a delay or perform it incorrectly. Repairing a malfunction is quite a labor-intensive and expensive task. You need to:

disassemble the dishwasher in half in order to get to the heater;
check the integrity of the wires going to the heating element and measure the resistance using a multimeter;
Check the parts of the control module, if a malfunction is detected, replace with a new one.

We would like to note that in order to protect household appliances and other devices from voltage surges, you can use a voltage stabilizer, which is purchased separately.

If you do not understand this topic, the best solution would be to call a specialist who will accurately diagnose the breakdown and fix it as soon as possible.

DIY dishwasher diagnostics

Before you start repairing the dishwasher yourself, you need to find the problem. And the machine itself can help with this, because modern devices have a special algorithm that, when a breakdown occurs, performs self-diagnosis and presents the fault to the user in the form of a digital code.

This code will be displayed on the display of the household appliance, and on more outdated models the error is displayed in the specific activation of LED indicators. Well-known manufacturers of household appliances, such as Zanussi and Electrolux, have made the self-diagnosis process automatic - the dishwasher independently determines the malfunction and displays the code. For models from other companies, failure detection begins after entering a certain key combination. Information about the correct sequence can be found in the operating instructions.

Stuck during washing

This defect is quite common on Electrolux car models - technicians advise turning it off for a few seconds and then turning it on again. Sometimes the freeze is repeated systematically; here this method is no longer valid. There is a manufacturing defect: it is necessary to replace the control module and test the operation of the machine in all modes.

Some Electrolux car models are cheaper to buy than to replace a completely expensive control module.

Cases of failure of this component are quite rare; failures are often caused by unstable operation of sensors - aquasensor, pressure switch and the like. Dishwasher repair will consist of replacing them.

Overview of the most common faults

In general, dishwashers from the Swedish brand are deservedly considered to be of high quality. Typically, Polish-assembled products are cheaper and break down more often. However, it is noted that Electrolux machines are distinguished by a durable body and a reliable circulation pump. Parts such as filters, gaskets, wiring terminals and other little things are traditionally made at a high level and rarely cause trouble.

Typical breakdowns of this equipment usually include the following malfunctions:

clogging of drainage and water supply elements;
improper heating of water during the specified wash cycle;
failure when executing the selected program, etc.

Very often, the causes of such malfunctions are violations of recommendations for using the device. If problems begin soon after the start of operation or occur too often, you need to check for such violations.

In addition, it doesn’t hurt to make sure that the dishwasher is installed correctly and connected to the sewer and water supply without any problems. The intricacies of installing and connecting a dishwasher are discussed in our other article.

Reason #1 - clogged drain/water supply

Poor quality of tap water is a common problem in many regions. Increased hardness, the presence of mineral inclusions and contaminants have a sad effect on the condition of household appliances, and dishwashers are no exception. For this reason, a filter must be installed before water enters the device.

It needs to be regularly washed, cleaned, and replaced in a timely manner. If damage has developed in it over time, you should not ignore it; you must immediately install a new filter. Otherwise, all contaminants will enter the dishwasher mechanism. Do not think that cleaning with chemicals will eliminate this effect. A reliable filter is essential.

The drain filter in this technique must be constantly cleaned; it can easily become clogged with food debris and other contaminants.

To clean it, you need to follow these simple steps:

disconnect the device from the water supply using the shut-off valve;
find the inlet hose with a filter from the dishwasher pipe, as well as from the tap;
remove filters;
rinse the filters and pipe to remove accumulated contaminants;
install all elements in place and reassemble.

If there is too much dirt, use a brush to clean it. Some owners believe that they can get by with just one drain filter, but practice shows that an additional filter in front of the supply hose will never be superfluous.

In addition, you should periodically carry out preventative cleaning of the dishwasher drain. To do this, you also need to use high quality products recommended by the manufacturer. Cleaning is done only with this product; there is no need to add other chemicals, rinse aid or salt to the dishwasher, and, of course, there should be no dishes there.

We recommend that you familiarize yourself with the features of cleaning a dishwasher at home.

Replacing the heating element of a dishwasher is a relatively simple operation if the technician has at his disposal a new, working element with the appropriate characteristics

To prevent breakdowns, you must strictly follow the operating instructions.

Here are the basic recommendations for using Electrolux dishwashers:

Before placing items in baskets, they should be cleared of food residues;
Only high quality products should be used for washing;
do not exceed or underestimate the amount of chemicals required for the machine;
you need to ensure that there is a sufficient amount of salt in the appropriate container;
Regularly check the condition of all filters and clean them promptly.

More detailed recommendations for using dishwashers are given in the following material.

Reason #2 - problems with the water heating device

If there are problems with heating the water during the cycle, most likely a malfunction of the heating element, sensors, or incorrect operation of the control unit is to blame. The weak point of many Western models of household appliances is their high sensitivity to sudden changes in network voltage. Such surges can damage the control board triac; this element will have to be replaced.

To correct the situation, you need to disconnect the dishwasher from the power supply, water supply and sewerage. The built-in machine will have to be completely dismantled. After this, using a tester, you need to check the serviceability of the heating element, as well as all electrical circuits. If you are unable to determine the fault yourself, you will have to contact a service center that has the appropriate diagnostic equipment.

To reflash or replace the dishwasher control board, you need to contact a service center; doing it on your own in this case can cause a lot of harm.

It is not difficult to prevent such a sad situation; just install a voltage stabilizer. The cost of additional equipment will pay off, because replacing the control board will cost much more.

Reason #3 - problems with the command apparatus

With regard to the electronics of the dishwasher, unprofessional intervention can lead to the fact that the situation will only worsen, and you will have to buy a new dishwasher.

A failure of the control module can also result in periodic freezing of the machine during the washing cycle. To correct the situation, you just need to turn off and then turn on the device again. If such a malfunction occurs rarely, there is no need to worry. But when the car has to be restarted over and over again, this most likely indicates a manufacturing defect.

To drain the water that has accumulated inside the dishwasher chamber, you will have to turn it over. After this, you need to restore the normal position of the sensors

Such a malfunction will have to be repaired by a service center after detailed diagnostics. This is the most expensive type of repair; in some cases, its cost can be comparable to the price of a budget dishwasher. But it also happens that diagnostics reveals a malfunction of a sensor; replacing it will cost much less.

Signs of a faulty thermostat

Serviceability can be determined by the continuous operation of the cooling system; the device cannot turn off on its own.

There are several signs that indicate a possible failure of the thermostat:

rapid growth of a layer of snow in the freezer and compartment;
violation of cyclicity in the operation of the device;
inability to turn on the refrigerator.

In these situations, the first thing to do is determine what state the thermostat is in. More accurate diagnostics are carried out by specialists.

Ice formation on the walls of the unit

To check the serviceability of the thermostat, the adjustment knob must be turned in the direction of increasing temperature while the compressor is running. If the thermostat is working, the sensor will mark the required temperature level and the compressor will turn off. If the engine continues to run, the part is replaced.

When the relay is working properly after diagnosing, food is removed from the refrigerator, it should work for 6 hours. You need to see how long the compressor will be idle. If the approximate time is 40 minutes, then the device can be used. Frequent switching on and off is controlled using the thermostat settings. If this cannot be done, it is changed.

Refrigerator won't turn on

In order to check whether the thermostat is working properly, disconnect the device from the network, remove the casing and inspect the wires. In old refrigerators, two pieces fit to the terminals. They must be removed and connected to each other with a piece of wire. If the compressor starts, then the relay is faulty, and if it doesn’t work, then most likely the motor burned out or the start-protection relay broke.

In modern models, the thermostat is connected to 4 wires of different colors, which differ depending on the purpose. For grounding, use yellow with a green stripe; you do not need to touch it. The rest are disconnected and connected to each other. The refrigerator is turned on, if it does not work, it means that the relay is working, the reason must be sought in the start-up relay or the compressor. And if the device turns on, then you should install a new thermostat.

Common PMM malfunctions

It’s unlikely that anyone will want to just delve into complex technology. Disassembling a Bosch, Candy, Siemens dishwasher may be necessary to find and fix the problem. To make it easier for you to navigate, let's consider typical problems:

Waste water is not drained. A common cause is clogging with food debris from dishes and small debris. First, the filter gets clogged, then the debris gets into the drain pump. This may cause damage. To check the parts, you need to remove the bottom of the PMM.
No pressure. You need to check the pressure in the tap. The installation may not have been completed correctly.
Water does not fill. The problem may be in the drainage system. We need to check everything step by step.
The machine is noisy or humming. Shards from broken dishes could get into the drain, or the bearings of the pump or motor could wear out.
Leak. The hose connections were broken, the hopper was damaged, and the Aquastop was broken. The equipment is subject to inspection.

Before starting disassembly, the machine must be properly prepared.

Checking the drain pump

You can clean the drain pump from dirt with your own hands. The location of the drain pump is also shown in the photo in the user manual.

You need to remove all the pump mounts and clean it with a thin object. After cleaning, check the movement of the pump blades. They should rotate easily. The photo shows that the pump is clogged with food debris and lime deposits.

All that remains is to fix the drain pump in place and check the operation of the dishwasher.

Dishwasher pressure switch failure

The pressure switch is a part of the dishwasher that controls water pressure. It happens that food gets into it, as a result of which the device gives incorrect readings. This causes problems:

poor quality dishwashing;
the water will run non-stop, which can lead to a flood.

On the forums, repair experts advise removing the pressure switch for inspection. Using pliers, remove the tube clamp of the part, carefully remove the entire part. The photo shows a pressure switch for an Electrolux dishwasher.

To check whether the device is working, you need to blow into the pressure switch tube. If you hear a click, the part is working properly. You can’t hear a click - the pressure switch on the Electrolux dishwasher needs repair.

You can watch detailed instructions for removing and checking the pressure switch yourself in the video.

In cases of breakdown of electronic parts, it is better to contact specialists who will repair Electrolux dishwashers at home.

To avoid having to send your Electrolux dishwasher in for repair, you should take proper care of the device.

The drain or fill path is clogged

This breakdown can be classified as systemic, since it is typical not only for Electrolux machines.

The degree to which pipes, hoses and filters are filled with debris depends on the quality of the water supplied from the water supply. The worse the water, the faster blockages occur. If there are too many minerals in your water supply, they will quickly build up on the inside of the filter, causing it to suddenly clog.

In this case, repairing the car will not be difficult, even if you decide to do it yourself.

Important! To avoid a recurrence of this breakdown, do not forget to remove the filter from time to time and clean it from deposits.

If the water is too hard, treat the machine as carefully as possible: check all elements of the filling system - filters, pipes and hose. You need to do it like this:

shut off the flow of water into the system by closing the tee valve;
unscrew the water intake hose together with the filter* from the tee tap and from the PMM body;
take out a small flow filter (located at the point where the hose is twisted with the equipment body);

rinse both filters and the hose (if it is difficult to rinse, clean with a special brush) and install back.

*Often users, along with installing a dishwasher, provide a small flow-through filter located on the tap side. If it is installed, then blockages will only occur in the filter attached to the PMM housing.

Important! If you use various water softeners, then in this case they are ineffective, since they protect exclusively internal parts and have nothing to do with filters and hoses.

If we talk about the garbage filter, as well as the hose and drain pipe, their blockages are more frequent. Repairers advise cleaning at least twice a month, and if the machine is used intensively, every 4 weeks. Prevention, which is described in detail in the instructions for your PMM model, will help prevent blockages.

Tracts of drain and fill systems

In all technology based on working with water, these systems are the first to become clogged. The water quality is to blame here, because in different regions it not only differs in hardness, but also contains numerous impurities of various minerals.

The first blow is taken by the filter installed at the entrance to the machine: all harmful impurities settle on its walls, so you have to constantly clean it of water stone. No chemical cleaning agents will help you - they only clean the inside of the hoses and pipes of the system.

The algorithm for cleaning the filter element is simple and can be done with your own hands:

shut off the water supply to the machine;
disconnect the inlet hose with built-in flow filter from the tap and the entrance to the dishwasher;
remove the strainer from the housing at the entrance to the machine;
rinse the hose and both filters, then put everything back in place.

Many users do not install an additional filter at the inlet of the drain hose, but in vain - this halves the load on the filter mesh element installed on the machine.

Prevention is the basis for the cleanliness of these elements; such measures for the Electrolux machine are popularly described in the attached operating instructions, but we will recall the main points:

Remove food residues from dishes before placing them in baskets.
Add detergents strictly according to the norm, only high-quality, proven ones, so that their undissolved sediments do not clog the filters.
Make sure you have enough regenerating salt at all times.
After each dishwashing, check both filters at the bottom of the machine tank and clean them of impurities.

For preventative cleaning of the drain system, purchase a patented product, pour it into the bottom of the tank and run the wash cycle on idle without adding detergents.

Preparation for subsequent disassembly

The principle of assembly and disassembly for built-in and free-standing dishwashers is the same. The only difference is that the built-in ones do not have a removable top cover and metal walls. By the way, free-standing models of dishwashers can be considered partially built-in. With the top cover removed, they fit perfectly under the tabletop, but at the same time they retain their own (and not furniture) façade.

Before starting to disassemble the dishwasher, be sure to disconnect it from the power supply. Then we turn off the water supply. Now you can work without expecting surprises.

A small addition - machines from different manufacturers may have different configurations of fasteners. For example, at Bosch and Siemens all fastening screws are made in the form of an asterisk of a certain size.

It is necessary to prepare the appropriate tool in advance. Screwdrivers, pliers and a set of keys will also come in handy.

We remove everything that may interfere with disassembly. Disconnect the water fill and drain hoses. Open the door and take out the removable baskets for dishes and attachments. It’s clear that there shouldn’t be any dishes there. If you find any remaining water, remove it with a rag or sponge. During disassembly, water will still come out. Therefore, there is no need to remove funds to collect it far.

Now you need to move the machine to a place where there is enough space to disassemble and place the parts to be removed. Try to prepare boxes or bags for storing small parts and screws.

Otherwise, subsequent assembly may be delayed. It is advisable to have a camera or phone with a camera nearby. During the process of disassembling and disconnecting tubes or wires, it is better to capture how everything happened. Then the reverse assembly process will not be surprising.

How to repair a dishwasher with your own hands?

If you have decided where to look for a breakdown, then our recommendations will help you deal with it. The first thing to do when an error occurs on the scoreboard is to restart the program. This will help eliminate system failure. The dishwasher control may malfunction after a sudden power outage.

Unplug the machine;
Wait 15 minutes;
Turn on the equipment.

If the code disappears, it may be due to a system failure. Obvious signs of breakdown require immediate repair.

Fill and drain system problems

The main malfunctions of the tracts occur due to blockages. The inlet filter, like the hose, becomes clogged with debris from the water supply. This is small debris, rust, scale. The filter is equipped with a fine mesh that protects the dishwasher system from debris. To clean the tract:

Close the inlet valve.
Disconnect the inlet hose from the housing. Water may spill out of it, so have a container or rag ready.
Behind it is a filter. Remove it with pliers.

Rinse the parts with warm water; if the mesh is heavily soiled, soak the mesh in a solution of citric acid.

Experts recommend installing a flow filter in front of the hose. It will cleanse the water of salts and make it “softer”.

Behind the filter there is a solenoid valve. When liquid is supplied, it opens the membranes and fills the tank. Voltage drops in the network lead to burnout of the valve coils, as a result of which they stop receiving module commands. If the coils burn out, the entire valve is replaced.

Problems with water supply can be caused by the Aquastop hose. During a leak, its sponge becomes saturated with liquid and blocks the passage. Install a new hose.

The drain path becomes clogged much more often. Poor removal of food residues from the surface of the dishes, infrequent cleaning of the drain leads to blockage, and then to pump malfunction. Damage can be prevented by following simple rules:

Clean dishes thoroughly before loading.
Remove dirt from the chamber at least once a week, or better yet, after each wash.
Use high-quality powders and washing tablets.

How to restore the drain yourself:

Open the bunker;
Remove the dish trays;
Unscrew the filter at the bottom and remove the mesh;

Clean the parts from debris;
Liquid accumulates in the mounting hole - remove it with a sponge;

Remove the protective cover;

Wear gloves and clear any blockage from the pump impeller. Be careful, fragments of broken dishes can block the operation of the impeller.
