How to disassemble a dishwasher

Water does not flow into the machine

If your dishwasher does not draw water, and you want to call a dishwasher repairman at home, do not rush to grab your phone - it is quite possible that the cause of the breakdown lies on the surface. First, check for the presence of water in the water supply - it could have been turned off during maintenance. Also, the repair is reduced to checking the inlet hose and the ball valve, which restricts the access of water to the dishwasher.

Lack of water may be due to faulty filters. One of them is installed in the inlet hose - it is a thin mesh that traps mechanical impurities. Repair comes down to checking and cleaning this mesh. If an additional coarse filter is installed in the water supply, make sure that it is working properly.

Another reason why the dishwasher does not fill with water may lie in the lack of operability of the inlet solenoid valve. Repair stages:

Checking the valve with an ohmmeter;
Checking the supply voltage to the valve;
Ringing the wires with a multimeter.

In some cases, the malfunction lies in the control board - here the triac fails, which controls the voltage supply to the valve.

When repairing a dishwasher with your own hands, pay attention to the most commonplace things - individual breakdowns are eliminated in a matter of minutes with your own hands. And calling the master through a single dispatching office or through an authorized service center implies a mandatory call fee (its amount varies from 500 to 1,500 rubles + work + cost of parts).

Additional tips and tricks

In order for the device to serve as long as possible, it is recommended to follow these rules:

It is forbidden to dry laundry on an oil heater. It will dry out rather quickly, but it will cause damage to the device. This is due to overheating of the elements of the device.
The surface of the oil heater can be hot. To prevent accidental burns, it is recommended to install a special protective shield on the device.
Wipe off dust from the device as often as possible. This will help prevent overheating and increase heat dissipation. In addition, dust can cause bad odors in the room.
It is forbidden to use such a heater in rooms with high humidity.
The device dries the air greatly, therefore it is forbidden to use it in very small rooms.
The device may only be used in an upright position. If the unit has been stored horizontally, it should be held vertically before turning it on. This will allow the oil to flow downward, eliminating the risk of overheating the heating elements.
It is forbidden to use adapters to connect the heater. This will create an incomplete contact. As a result, the device can be switched on and off periodically. As a result, it will simply fail.
It is not recommended to leave the device turned on when leaving home. Do not place the device near upholstered furniture or curtains.

>Oil cooler repair has a number of features. To achieve success in this matter, it is necessary to clearly identify the causes of the breakdown and follow the basic recommendations.

Getting ready for disassembly

In the Bosch dishwasher, as in other brands of machines, all the most important parts are located at the bottom of the dishwasher. At first glance, it seems that there is nothing difficult about turning the car upside down, removing the pallet and gaining access to everything you need. In fact, in practice, everything looks a little more complicated, but more on that later, first preparation.

In any business, preparation is the basis of all work, about half of all failures are the result of a poorly prepared workplace, tools and materials, as well as a lack of necessary information. In order not to get into a mess, let's start preparing the workplace. Naturally, few people have a full-fledged workshop at home, if you have - well, no - it doesn't matter either. Please do the following.

Slide the Bosch, Siemens (or other brand) dishwasher out of the niche in the kitchen unit, then turn off the water supply and unplug the power cord.
Disconnect the inlet hose as well as the drain hose.
In a place convenient for work, spread cellophane, several rags on top, and put the dishwasher on them.

"Dishwasher" is ready for disassembly. Now we are preparing the instrument. Let's note right away - the dishwasher can be disassembled with almost bare hands, the maximum that we need is this:

Phillips and flathead screwdrivers;
pliers;
thin awl.

To carry out repairs, you may need another tool, for example, a multimeter, tweezers, a soldering iron, side cutters, an adjustable wrench, but this is a separate story for a separate article.

How does a dishwasher work?

Perhaps we are in vain repeating common truths, but I think it will not be superfluous. To properly disassemble and then assemble a "dishwasher" from Bosch (or another brand), you must have at least a superficial understanding of its structure and how the dishwasher works. In general terms, the device of the dishwasher is shown in the picture below, in general, in order to conduct a quality analysis, this will be enough for you.

How to dismantle the top panel on PMM of different brands?

Consider the procedure for dismantling the panel in typewriters from leading brands.

Manual for Bosch and Whirlpool

The easiest way is with a Bosch dishwasher. Proceed like this:

Expand the technique with the back of the case towards you.
Locate the latches that are located at the top of both sides of the case.

Click on them. If they do not give in, stock up on a screwdriver, but work carefully so as not to break off the plastic fasteners.
When you open the fasteners, slide the cover away from the grooves. If standing on the side of the hopper door, pull towards you.

The manual for whirlpool machines is the same - the top panel is also held in place by plastic latches.

Manual for Indesit and Hotpoint Ariston

The procedure is almost the same, with minor differences:

Expand the technique with the back towards you.
There are two screws at the top of the side end.

Unscrew the fasteners with a screwdriver.
Slide the cover towards you.

Procedure for PMM of the Beko brand

Your actions and the rules for their implementation:

Find the screws on the case.
Twist them with a screwdriver.
Set the screws aside so as not to lose.
Slide the cover back a little.
Pull up. Ready!

In some Beko models, the top cover can be removed only together with the back panel. In this case, the work is carried out as follows:

The back of the case is fastened with 5 self-tapping screws.
Unscrew the fasteners with a screwdriver.
Hide the screws in a safe place to avoid losing them - it can be difficult to find similar fasteners.
Tilt the panel at right angles to the body.
Remove from the grooves and set the part to one side.
Remove the part you need and refit the cladding.

Diy dishwasher diagnostics

Before proceeding with the repair of the dishwasher with your own hands, you need to find the malfunction. And the machine itself can help with this, because modern devices have a special algorithm that, when a breakdown occurs, conducts a self-diagnosis and presents the user with a malfunction in the form of a digital code.

This code will be displayed on the display by the household appliance, and on older models, the error is displayed in a certain operation of the signaling LEDs. Well-known manufacturers of household appliances, such as Zanussi and Electrolux, have made the self-diagnosis process automatic - the dishwasher independently detects the malfunction and displays the code. For models of other companies, the breakdown detection begins after the introduction of a certain key combination. The correct sequence can be found in the instruction manual.

Various error codes using the example of a dishwasher from Indesit:

E1 - signals about the absence of liquid heating. The problem is associated with a malfunction of the heating element, thermostat or control module.
E2 - pressure switch malfunction. A pressure switch is a sensor that provides the user with accurate information about the presence of water in the tank and its amount.
E5 - the water level exceeds the norm.
E6 - Aqua Sensor does not work. This device detects the degree of contamination of the water. Triggered during the last rinse of items.
E9 is the most common error that signals a malfunction and replacement of the heating element.
E15 is a code signaling both the activation of AquaStop and the breakdown of this function.
E17 - lack of water in the dishwasher.
E21 - there is no normal fluid circulation, the cause is a pump malfunction.
E27 - the voltage of the industrial network does not correspond to the norm.

Why remove the clipper?

Indeed, why pull the machine out of the built-in kitchen, for what purpose to do it? She stood there for many years and let her stay on.

The first and most obvious goal is to repair the car. Many breakdowns can be eliminated by gaining access to the parts of the pallet of the machine, and such access can only be obtained by dismantling the built-in dishwasher. There are no other options.
The second goal is to replace the dishwasher. Old equipment can be sold to someone else, and the proceeds can be added to buy a new "home assistant". But in order to sell an old car, it must be pulled out correctly so as not to damage anything and not completely spoil the presentation of the equipment.

Removing the dishwasher incorrectly can lead to the fact that it cannot be re-installed.

The third goal is more global - the renovation of the entire kitchen with the replacement of furniture. When disassembling a kitchen set, it is in no way possible to leave a typewriter in it. It must be pulled out, and this must be done carefully, since further operation of the "home assistant" is planned in the future.

As you can see, there are more than enough reasons. If one of them touched you, read our publication to the end and you will understand how to properly pull out your dishwasher equipment.

Why not invite a master?

The reasons are purely economic. If you have money and you do not mind sponsoring a master a little, then you do not need to read this article to the end. Call a specialist, he will quickly come and do everything. If you don't want to pay extra money, take note of our arguments.

Firstly, the master almost always takes a separate fee for dismantling Bosch dishwashers and other brands. The cost of the service can go up to $ 40. And if diagnostics and repairs are required in the future, you will pay separate money for this. Secondly, calling the master, you will waste time, because due to busyness, specialists rarely come very quickly. Thirdly, a man and even some women want to show independence, if not in all, then in many issues. Everyone wants to feel like a jack of all trades. It is not always correct to indulge your self-esteem, but in our case it is permissible.

The process of removing the typewriter

Well, you decided to pull the machine out yourself from under the table top or from the cabinet, let's get to work, but first, let's prepare the tools. Inspect the machine's mountings and find the correct screwdrivers and wrenches. For the most part, you can get by with a screwdriver with a set of nozzles. We take it and go to the typewriter.

First, we pull out the plug of the power cord from the outlet, and also shut off the flow of water into the machine.
Next, unscrew the strap of the narrow front panel, which is located under the door of the machine. Not all dishwasher models have this bar. Take the Electrolux line of dishwashers, for example. If you have such a machine, skip this step.
Unscrew the inlet hose and substitute the bucket so that the remaining water flows into it.
We find the place where the drain hose connects to the siphon fitting and detach the hose.

Most likely, the hose is pulled to the fitting by a clamp, so be prepared to loosen or cut if the clamp is plastic.

We open the door of the washing chamber, find the fasteners that go out and unscrew them. These screws secure the appliance to the table top.
We unscrew the fixing screw and lower the legs of the machine to the limit.
We grab the body of the machine and, with swaying movements, push it towards ourselves. You need to act carefully so as not to drop the machine on your feet.

We can say this is where the extraction of technology ends. A number of built-in dishwashers have furniture fronts, which can also be removed beforehand, but this is not necessary. The machine can be pulled out with the facade, but it is better to remove it all the same, so as not to accidentally scratch or chip. This is not difficult to do. You need to open the door of the machine, unscrew the screws at the edges on the inside of the sash, pull off the facade.

Be careful, because the facade is quite weighty and can slip out of your hands. Remove the facade by sliding it slightly up and then towards you

So you are convinced that dismantling the dishwasher from the built-in kitchen is quite a simple matter, not like completely disassembling the dishwasher. Everything can be done by hand and save some money for the family. The main thing is to follow our instructions, and everything will be fine. Good luck!

The main malfunctions of the PMM

The reasons for the failure of the dishwasher are associated with its structural elements.

Water does not heat up

Lack of water heating can be caused by problems:

with power supply;
the state of the heating element;
temperature control sensor;
control unit.

A power failure can be caused by a failure of the outlet, surge protector, power cord. The cause of the breakdown is power surges in the network. Failure of the tubular electric heater occurs due to the main element - a metal spiral, the service life of which has ended or there is a low-quality material. The heating element is turned on and off by a signal from a temperature sensor, the breakdown of which makes heating impossible. A failure in the ECU program is one of the reasons for the termination of the PPM.

The machine shocks

If from the body of the dishwasher, its metal parts, it shocks, then this means a breakdown of the insulation in the electrical wire, pump, electric heater.

Overheating of water

The electronic control unit and the heating element operation sensor are responsible for the temperature regime. Exceeding the degrees provided by the program means a failure in the controllers and the program.

Lack of drain

The drain system can fail for several reasons:

sewer blockage;
drain hose;
filter;
breakdown of the pump.

Failure of the drain system will lead to overflow of water from the PMM onto the kitchen floor.

No water set

Insufficient water in the dishwasher is associated with:

with poor water supply;
clogged filters;
failure of the electromagnetic inlet valve;
malfunction of the water level sensor (pressure switch).

The work of the PPM with a shortage of water will be unsatisfactory: food contamination and detergent will not be completely removed.

Overflowing water

One of the malfunctions of the dishwasher is premature shutdown due to the activation of the leakage protection sensor. Some models have trays into which water is drained in case of a blockage in the hose.

The safety tank is equipped with a float. When the pallet is filled with water to a certain level, the float floats up, closing the circuit that turns off the PPM.

The reasons for the defect in the dishwasher:

installation not horizontally, overflowing;
an excess of detergent, the foam of which distorts the water level;
due to a malfunction of the water level sensor, excess volume is pumped in and discharged into the sump;
breakage of the float, jammed in the upper position;
burst hose;
crack in the bottom of the tank.

If the dishwasher is not equipped with a protective tray, then any reason will cause water to leak onto the floor, which can cause flooding of neighbors.

Doesn't wash dishes

A dishwasher is a complex device that must be used in accordance with the manufacturer's instructions. It indicates the norm, loading scheme, the amount of detergent. Ignoring these requirements will affect the quality of the wash.

To clean surfaces from contamination, hot water under a strong pressure is required. If scale has formed on the electric heater tube due to hard water, the water will not heat up to the required temperature. Limescale has low thermal conductivity, which makes the operation of the heating element ineffective. The narrowing of the diameter of the nozzles due to contamination reduces the flow of water to the basket with dishes, which makes it worse for washing.

ECU breakdown

The electronic control unit is responsible for the consistency of the operations performed. Each PPM model has its own module specified in the instructions. If it fails, it is impossible to reanimate the unit. The cause of a breakdown may be a voltage drop, condensation.

Types of facades, functions

The facade for PMM is decorative cladding that is in harmony with kitchen furniture. Attaches to the car door. Practical, durable MDF panels... They can be laminated, covered with colored foil, fastened with original fittings, various decorative elements. Hanging chipboard, PVC is a big risk. These materials are easily deformed by vibration, high temperature, moisture.

Sheathing functions:

Simplification of the choice of technology. You don't have to worry about the color of the case, but focus on the technical characteristics, since the dishwasher will still not be visible.
Protection from children. The machine hidden behind the door will not become a “victim” of children's curiosity.
Isolation of noise. Additional panel absorbs noise. German built-in models such as Siemens (Siemens), Bosch (Bosch), Miele (Miele), Hansa (Hansa) are equipped with special noise-absorbing gaskets, which are inserted between the door and the front panel.

Types of fasteners

The casing can be attached to the door with self-tapping screws (option for fully built-in models), fixed on hinges (for partially built-in models). The slide mount is often used in the Gorenie, Ikea, Electrolux, Beko modifications.

Sheathing dimensions

Depend on the dimensions of the PMM. Standard machine width 60 cm (full size), 45 cm (narrow). The common height is 82 cm. Dimensions may vary greatly from standards. We recommend purchasing the headset after purchasing a dishwasher. So that it can perfectly fit under the table top, lock into place. For example, Ikea kitchens are suitable for all models of dishwashers from this manufacturer. The Leroy Merlin store sells custom-made household appliances. If the facade is larger than the door, it will rest against the plinth when opened.

Dishwasher long fronts: what to do?

Try to adjust the height of the dishwasher by twisting the legs. You can make a gap in the plinth equal to the thickness of the facade, the door, plus a couple of millimeters of stock.

Consider the main breakdowns of machines

Most of the dishwashers supplied to the Russian market are manufactured in Poland and account for about 90%. The quality of their components and assembly can be compared with similar units of German and Swedish companies, however, as they say, there is no need 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 circulating pumps was approached really reasonably, they had a high working resource;
the manufacturer is sensitive to small details, such as: wires, clamps, terminals, rubber bands and filters, which in turn made it possible to increase the period of trouble-free operation of the dishwasher.

There were no especially critical drawbacks during the operation of the dishwasher, one of them, like everyone else, is inherent in typical breakdowns, from which it is rather difficult to be protected. Let's list them below:

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

How to disassemble a radiator

To repair the heater, you need to identify the cause of the breakdown. For this, it is recommended to disassemble the device. To begin with, it is worth preparing everything you need:

an item for prying a plastic panel - it is desirable that it has a wedge-shaped shape;
screwdriver;
alcohol or cologne;
tester;
sandpaper;
soft napkin;
brush;
file.

Before starting disassembly, the device must be disconnected from the power supply. It is strictly forbidden to connect a disassembled device. All models of heaters are different, therefore there is no standard algorithm for the procedure. However, there are several options for solving the assigned tasks.

But most often, a spring latch is used as a retainer for the plastic panel. In this case, you should touch the surface with a plastic object or a product made of another material. This must be done very carefully to avoid damaging the case. You will be able to feel the area where the latch is located. If you press harder on this area, it will be possible to bend it.

If you have little skill in analyzing the technique, it is worth photographing the entire process of shooting. It is recommended to lay out bolts and nuts during disassembly. This will help reassemble the instrument after the process is complete. Experts advise not to rush to disassemble the device. Some problems can be identified without looking inside the device.

Should I call the master or not?

The answer depends on the consumer: if there is an opportunity to pay for the services of a specialist and there is no desire to bother with dismantling the equipment, the problem is solved with one call. If the user is sure that he can dismantle the built-in dishwasher himself, it makes sense to prepare for the process, having previously studied its nuances.

It doesn't matter what kind of PMM you have - the prestigious Bosch ("Bosch") or the budget model of the Chinese assembly, the master will have to pay separately for dismantling. If you cannot remove the built-in appliances yourself, you will have to shell out about 40

e. Cons of this solution:

you are losing money;
you are wasting time - sometimes the master has to wait a long time.

To get the dishwasher yourself, you will need:

How to repair a dishwasher yourself

2. The processor gives the command "Water intake":

Do-it-yourself dishwasher repair. The water inlet valve opens. The dishwasher is drawing up water. The level (amount) of water collection is controlled by the water level sensor rice 5 (in Figure 1, see number 7).

The sensor is set to be triggered at a certain amount of water (sufficient for high-quality dishwashing). When a sufficient amount of water has been collected, the sensor sends a signal to the processor.

How to repair a dishwasher yourself. The processor received a signal from water level sensor, closes the water intake valve.

3.4. The processor gives the command "Start washing":

Do-it-yourself dishwasher repair, do-it-yourself dishwasher repair. The circulation pump rice 6 starts to work (see figure 1 under number 12).

The circulating pump creates enough pressure in the dishwasher to circulate water. Water enters the impellers (sprinklers) rice 7 (see figure 1 under number 3), then into the holes of the impellers.

From the holes of the impellers, water with a certain pressure force washes the dishes loaded into the baskets of rice 8 (see figure 1 under number 1). The impellers begin to rotate, which facilitates the dishwashing process.

The dispenser (dispenser) Fig. 9 (in Fig. 1, see number 16) with detergent is opened. Detergent gets into the dishwasher.

5. The processor gives the command "Water heating":

The mains voltage is supplied to the heating element fig10 (see figure 1 under number 20). The water is heated up to the value corresponding to the selected washing program.

The value of the water heating temperature is controlled by the water heating temperature sensor rice 11 (see figure 1 under number 4). When the water temperature reaches the required value, the sensor informs the processor about it.

The processor disconnects the heating element from the mains, thereby stopping heating. The dishes will continue to be washed for some time. The washing time is controlled by the processor according to the selected dishwashing program.

6.7. The processor gives the command "Drain water":

The dishes are washed. The drain pump rice 3 starts to work (in Figure 1, see number 8), pumping out the water. The water has been pumped out. The processor informs about the lack of water by the water level sensor rice 5 (see figure 1 under number 7). The next operation is the rinsing operation.

Progress

Having passed all the points of the preparatory stage, you can start repair work. It will not work right away to set up or remove the door - you need to start slowly but surely to disassemble the PMM. First you need to remove the side walls and the top cover, behind them is the smooth opening mechanism. Further disassembly is not required. Outline, just in case, the stages of disassembly so as not to be mistaken:

Unscrew the fasteners that hold the right side wall. Remove and set the panel aside.
Repeat the operation for the second wall.
Unscrew the screws holding the top cover, remove and set it aside.

Under the cover, you will see two fasteners, from which cables extend in different directions. They run along both sides of the body, connecting at the end with springs. This is how the smooth opening mechanism looks like, which needs to be adjusted.

Armed with a hexagon, tighten the screws from which the cables pull the springs. If the door is difficult to open, you need to loosen the tension on the springs, and if the door does not hold, you should increase the tension.

It is much worse if one of the cables bursts from the load. In this case, the second works for two, therefore, does not perform the functions assigned to him. Regulation is pointless - you need to change the damaged element. Follow this scheme:

loosen the screw that holds the torn cable;
remove it from the screw with pliers;
disconnect from the spring;
buy a new original or similar item;
unpack;
put the cable on the spring;
grab one end with pliers, pull and hang on the screw;
adjust the tension;
assemble the typewriter.

If the door cannot be adjusted, more serious repairs will be required.

Typical failures

According to statistics, 90% of the cars under the Electrolux brand that are sold in Russia are manufactured at factories in Poland. Their quality is slightly worse than that of analogues from Germany, but the pricing policy does not bite either. Masters from service centers, especially for the Russian consumer, note the following advantages:

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

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

hoses, branch pipes of water supply and drainage systems are often clogged;
water does not heat up according to the mode;
sometimes there may be problems with the execution of the set dishwashing programs.

In order not to make frequent repairs to the dishwasher, you must always pay attention to the state of technology, adhere to the recommendations set out in the instructions

If the capacitor is defective

Power surges and other negative factors can cause the Electrolux or any other fuse to break. Therefore, if the dishwasher does not turn on, and the outlet, cord and hose with water supply have been checked for serviceability, then it is necessary to check the condenser. If the fuse is blown, this is another reason the dishwasher won't turn on.

To diagnose this important part, the machine will have to be disassembled, since the fuses are located under the pallet. It is recommended to prepare a rag in advance, as stagnant water may spill out of the equipment

You will also need a multimeter device to measure resistance.

Procedure:

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

If a lack of resistance is found, then the capacitor is out of order. You need to remove it and buy a similar one. We put a new fuse in place according to the scheme. If even after these manipulations the dishwasher does not turn on, then you should contact the master for help.

Elimination of internal and external blockages

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

Why take out the dishwasher?

Installing built-in appliances is a whole story. So why extract it? There are several good reasons for removing dishwashers:

Breakdown of the PMM. There are problems that cannot be dealt with without completely removing the device.
Replacement of the device. Any technique has its own resource, so sooner or later it is necessary to update the "park". It happens that the dishwasher is still working, but its owner wants to replace it with more:

- functional;

- roomy;

- economical.

If you carefully take out the device, you can sell it - this will recoup some of the costs of buying a new model. Inexperienced actions during dismantling will lead to damage to the PMM, and it will not be possible to profitably realize it.

Kitchen renovation. If you have to disassemble the kitchen set, then the PMM will need to be removed

In order to be able to use the device again for its intended purpose after repair, it is necessary to proceed with extreme caution.
