Do-it-yourself Siemens dishwasher repair

Understand the device of the dishwasher, familiarize yourself with the main components of dishwashers (Fig. 1), their purpose and principle of operation.

LET'S CONSIDER IN DETAILS THE DEVICE AND PRINCIPLE OF OPERATION OF THE DISHWASHER:

Rice. 1 Dishwasher device

The device of dishwashers, regardless of the manufacturer and its model, can be represented by a single diagram in Figure 1. The main functions that the dishwasher performs after pressing the start button and closing the door are:

1. Water drain (usually at the start of any selected program).
2. Bay of water.
3. Start of the washing process.
4. Adding detergent (laid at the stage of loading dishes).
5. Water heating.
6. Washing process (takes time depending on the washing program you have chosen).
7. Draining.
8. Water inlet for rinsing.
9. Rinsing.
10. Draining.
11. Drying.

Eleven main functions are responsible for high-quality dishwashing. Eleven main functions are performed by the functional units (parts, devices, peripherals) of dishwashers. The on/off sequence of the dishwasher peripherals is controlled by an electronic control module (hereinafter referred to as the processor) similar to that shown in Figure 0.

Wash program - a sequence of instructions executed by the processor. Washing programs are different:

1. time (execution time).
2. the degree of water heating (from 50 ° C to 75 ° C).
3. the presence or absence of a pre-soak function.

Consider the main components of dishwashers and their functional purpose using the example of a phased implementation of a washing program from start to completion.

You have selected a washing program, added detergent, added rinse aid (optional), pressed the start (start) button and slammed the dishwasher door. What happens next?

1. PROCESSOR CHECKS DOOR CLOSING AND ISSUES THE COMMAND "WASH AFTER PREVIOUS WASH OPERATION":

The lock is responsible for closing the door Fig. 2 (in Fig. 1, see number 15). If the door is correctly closed, the lock closes the contacts. This is a signal to the processor that the door is closed. Having received the “door closed” signal, the processor sends a command to the drain pump (fig. 3, see number 8 in figure 1) “drain the water”. The drain pump begins to perform its function.

At the same time, the processor with a frequency of 5-6 seconds, within 2-3 minutes, gives the command "water inlet". The water inlet valve Fig. 4 (in Fig. 1, see number 17) opens, water enters the dishwasher. The drain pump runs constantly, pumping out water. After a certain period of time, the drain pump stops working. The rinsing operation from the previous dishwashing is completed.

2. PROCESSOR GIVES THE COMMAND "SET OF WATER":

The water inlet valve opens. The dishwasher is taking on water. The level (quantity) of water intake is controlled by the water level sensor fig. 5 (see fig. 1 under number 7). The sensor is configured to trigger at a certain amount of water (sufficient for high-quality washing of dishes). When enough water has been collected, the sensor sends a signal to the processor. The processor, having received a signal from the 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 fig6 starts to work (in figure 1, see number 12).The circulation pump creates enough pressure in the dishwasher to circulate the water. Water enters the impellers (sprinklers) Fig. 7 (in Fig. 1, see number 3), then into the openings 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 (in Figure 1, see number 1). The impellers begin to rotate, which contributes to the process of washing dishes. The dispenser (dispenser) Fig. 9 opens (in Fig. 1, see number 16) with detergent. Detergent enters the dishwasher.

5. PROCESSOR GIVES THE COMMAND "HEAT WATER":

Mains voltage is supplied to the heating element fig. 10 (see fig. 1 under number 20). The water is heated to the value corresponding to the selected washing programme. The value of the water heating temperature is controlled by the water heating temperature sensor Fig. 11 (in Fig. 1, see 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 the heating. Washing dishes continues for some time. The washing time is controlled by the processor, according to the selected dishwashing program.

THE PROCESSOR GIVES THE COMMAND "DRAIN WATER":

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

THE PROCESSOR GIVES THE COMMAND "WATER FILL" TO RINSE:

The mains voltage is supplied to the water inlet valve. The valve opens to allow water into the dishwasher. The water level sensor monitors the filling of a sufficient amount of water. When the amount of water in the dishwasher reaches the required value, the water level sensor informs the processor “water is full”.

The processor disconnects the water inlet valve from the mains, thereby stopping the flow of water into the dishwasher. The processor turns on the circulation pump. Water under a certain pressure enters the rocker arms (sprinklers), the process of rinsing dishes begins. The processor sends a command to turn on the water heating. The level of water heating is controlled by a temperature sensor. When the water temperature reaches the required value (the processor informs the temperature sensor about this), the heating process stops. The rinsing process itself continues for some time. The value of the rinse time is written in the program, which the processor reads from external or internal memory.

10. THE PROCESSOR GIVES THE COMMAND "WATER DRAIN" AFTER RINSE:

At the end of the rinse phase, the drain pump turns on. The drain phase begins.

THE PROCESSOR ISSUES THE "DRY" COMMAND:

The drying process starts. To dry dishes, cold tap water is automatically filled into the heat exchanger. All moisture quickly condenses on the cold left wall of the washing chamber and flows into the drain. After the drying process (15-20 minutes), the drain pump is turned on in order to drain the remaining water after drying. Next, a signal for the end of the washing process is heard.

That's all. This is the basic scheme by which almost all dishwashers work. Having studied the device of the dishwasher, you can repair the dishwasher yourself. Additions and deviations from the functions of the main modes are nothing more than an additional service from the manufacturer.

AQUASTOP SYSTEM:

Most dishwasher models are leak-proof. The bulk of budget models of dishwashers have a tray with a float switch that stops work when a leak is detected. Models of the middle and top class are equipped with an emergency valve that blocks the water supply to the machine. See pictures below (aquastop hose and float pic 12).The aquastop hose is attached directly to the water supply pipeline, the float is located in the dishwasher tray.

In other words, the AquaStop system consists of a sump with a float and a microswitch, a heavy-duty flexible hose and an electrovalve module that is attached directly to the water supply system (Fig. 12). Water enters the sump due to a hose leak or depressurization of the machine. When a certain amount of water is collected in the pan, the float rises and closes the contacts of the microswitch. The supply of electricity to the safety valve is immediately cut off, the valve closes and shuts off the water supply. At the same time, water is pumped out of the base of the machine.

If the dishwasher refuses to work, analyze the information above, analyze the list of possible faults below and perhaps you will get the answer to the question “what happened?” and troubleshoot the dishwasher yourself.

Below is a list of common dishwasher problems and how to fix them. This information was accumulated over the years of practice and acquired structural forms. The information will be useful for both beginners and those who are used to repairing everything with their own hands. Below is a list of fourteen points that characterize the malfunction of the dishwasher. Knowing the contents of the items will make it easier to learn the secrets of repair. Each item contains a detailed description of the logical troubleshooting path of the item name. Knowledge will help DIY dishwasher repair. Repair your dishwasher

Your dishwasher doesn't work. What to do?

Experts will tell you that when the dishwasher, for some reason, is out of order, you need to call the craftsmen who will not only carry out diagnostics, but also repair dishwashers + a forum where there are a lot of arguments that minor repairs can be do it yourself. First of all, the dishwasher repair manual and this video will help you.

Many housewives have long acquired special devices for washing dishes, they make life much easier and save time. But they break as often as all other household appliances. Repair of the dishwasher Bosch SRS (Bosch), Ariston (Ariston), Electrolux ESF (Electrolux) and others can be done at home with your own hands, without contacting a service center.

A dishwasher is a device designed for washing and rinsing various dishes (from dinner plates to pots, pans, etc.). The external simplicity of the design is very deceptive, because this device has a number of modules, regulators and other control mechanisms.

It is built-in and free-standing. The inline view technique is considered more convenient to use because it does not require additional space. But at the same time, its repair is somewhat complicated by the lack of quick access to structurally important parts. The schema looks like this:

Photo - dishwasher design

On the drawing you see the standard device device. On the control panel (1) you select and set the various operating modes, here you define the temperature, flow rate and water pressure. The time is controlled by a timer (14). When the settings are made, you need to load the dishes into the washing chamber. After the door latch (15) slams shut, the contacts will close and, like in a washing machine, water will begin to flow. Depending on the design, the machine can be connected to a boiler or boiler, then warm water comes from a hot water hose (7), at the outlet of which there is an inlet valve (9), or it can heat the liquid on its own using a heating element (12).

When the water is ready, it begins to be sprayed onto the dishes from above and below with the help of sprayers (2,3). Their work is controlled by a valve (4), which is also responsible for ensuring that there is not a lot of water in the chamber. When the dishes are washed, the soapy liquid is removed by the drain hose (5), the chamber is rinsed. The latch opens and you can unload the dishes. In addition, the diagram shows:

• 6 - this is a power cable that connects to the power supply network;
• 8 - filter, with the help of which the control and necessary purification of running water is carried out;
• 10 - motor;
• 11 - pump;
• 13 - gasket.

This device is very similar for all modern dishwashers: Ardo (Ardo), Elenberg (Elenberg), Beko (Veko), NEFF, Hansa (Hansa), Candy (Kandy) and others. The system can be complicated by the presence of various control functions, for example, additional cleaning or blowing dishes. Before starting repairs, be sure to review the user manual and operating tips from the manufacturer - it may not be collapsible.

Typical malfunctions of machines:

1. Water is not supplied. This could either be a pump problem or a clogged filter;
2. The device turns on but does not work. Sometimes it happens that the Samsung (Samsung), Hotpoint, Silanos SER or Indesit (Indesit) machine seems to turn on, but it cannot start. It could close the motor or pump;
3. Doesn't turn on at all. The motor windings burned out, the power wire is damaged, there is no voltage in the outlet;
4. The water does not drain. Probably, the sewer, the drainage pipe is clogged, or the drain pump is faulty;
5. Water flows out of the door during operation. This, unequivocally, broke the door lock, which should jam and ensure the tightness of the container;
6. No reverse. Reverse is a very important function of a domed and conventional dishwasher, in the absence of which it is necessary to repair the timer or replace the motor windings;
7. Water is not heated. A very common malfunction, which indicates a breakdown of the heating element or a malfunction of the time sensor, timer. If the machine is connected to the boiler, then it makes sense to check it for performance;
8. Dishes do not dry.The fan and motor are responsible for this function.

Most of the problems mentioned above can be fixed on your own. The filters are easy to clean. Depending on the design, it may not even be necessary to disassemble the device. To clean it, you need to remove all the grates from the chamber, there is a filter at the bottom under them. It can be threaded or simply inserted into a drain hole. Take it out and rinse it under running water. In order to eliminate the smell, it is also recommended to rinse with detergents.

Step-by-step instructionwhat to do if the pump of the Zanussi ZDTS (Zanussi), Siemens (Siemens) or Krona BDE (Krona) machine is blocked:

1. You need to turn off the water supply and unplug the power cord;
2. Unscrew the filter cylinder and pull the cleaner out. The pump vanes must be carefully unscrewed and cleaned. In particular, pay attention to the holes, which are often contaminated with grease or food residues;
3. Under the filter is the pump cover. It must be pressed until it clicks and removed from the container;
4. The pump must be cleaned with a sponge or soft brush;
5. Carefully inspect its walls, broken dishes sometimes get here, which can break the tightness of the part. If cracks or holes are found, the pump will have to be changed.

If the fault is in the motor or other internal part, then you will have to disassemble the dishwasher for repair. This process is quite fast. You just need to unscrew all the screws that hold the case. Note that instead of removing all fasteners, try to pay attention only to those that are located near the breakage site - this will speed up the process.

Instructions on how to disassemble a Whirlpool (Whirlpool), Siemens, Miele, Kaiser (Kaiser), AEG (AEG) dishwasher for engine repair:

1. You need to remove the lower front panel. Under it is the connection of the engine and pump, you also remove them;
2. Water may remain in the pump and pipes, so prepare a container in advance to drain it;
3. First, the pump cover is removed as described above. After the pump itself is turned out of the base and removed. Underneath is the engine. Gaskets are often installed between parts, so be careful not to damage the seals;
4. Check the functionality of the parts. Reverse installation is performed in the same way.

If you are not confident in your abilities, then it is better to immediately turn to specialists. A high-quality master will not undertake to carry out urgent warranty repairs after preliminary intervention in the design of the dishwasher.

There is no problem-free technology - even premium-class representatives fail. Malfunctions also occur in the Siemens dishwasher. According to consumers, they break down half as often as other brands.

What to do when a breakdown occurs? Pay attention to the work of PMM Siemens, diagnose the problem and fix it yourself. How to do this, read below.

Siemens dishwasher error codes are collected and described in detail in a separate article.

The main causes of breakdowns of the Siemens dishwasher:

• The machine does not work, the display does not light up, or the program freezes. The reason may be the lack of voltage in the outlet. If you press the button and the program is not selected, the contacts may have burned out.
  How to connect the car? You need to disassemble the panel, clean or replace the contacts.
• PMM does not draw water. Check the water supply immediately. Then inspect the inlet system: the reason may be a blockage in the inlet hose, flow filter, intake valve.
• Why is the dishwasher not washing dishes well? Perhaps the water supply valve is clogged, then the water pressure is too small, so the dishes are not washed well.The nozzles on the rocker that sprays water can also become clogged. It is necessary to clean the system for normal water flow.
• The equipment turned on as usual, but water is not drawn in, washing does not start. The reason is a loosely closed door.
  How to adjust the door? It is enough to tighten the hinges of its fastening so that the lock normally passes into the hole.
• When there are problems with draining, the entire drain system is checked: filter, pump, hose. Details are cleared of blockage. If the pump is broken, then the part changes.

• If the machine draws water but the wash does not start, the circulation pump is the problem. Need diagnostics and repair.
• The dishwasher activates an emergency shutdown. The reason is in the control module - in this case it is better to contact the wizard.
• The water does not heat up. Need to check the heating element, thermistor. The heater is called, in case of a malfunction it is replaced. The thermistor also needs to be replaced.
• Dishwasher does not dry dishes. If your model has a drying function, then the cause of the breakdown is in the drying fan or its wiring.

You figured out the main faults. Now you need to figure out how to fix the breakdowns in the Siemens dishwasher.

Here are detailed instructions on how to start and repair the dishwasher. Let's start with the most common problem.

The quality of the tap water leaves much to be desired. Foreign-assembled dishwashers are not designed for such impurities in the water, so the filter mesh in front of the valve quickly becomes clogged. To reduce the number of blockages, install a flow filter in front of the mesh. Periodically clean both elements, then the water will flow into the machine normally.

1. Shut off the water supply.
2. Disconnect the inlet hose from the PMM body.
3. Remove the mesh filter and rinse under running water.
4. If the dirt is very ingrained, leave the filter to soak in a solution of water and citric acid (dissolve 100 g in 2 liters).
5. Install the elements in reverse order.

If there are problems with the drain system, the water will not go away after washing, overflow may occur. Also, blockage causes the program to stop. For example, you start the car, water is collected, but the wash does not start.

How to disassemble and clean the system:

• Disconnect the machine from the power, turn off the water.
• Open the hopper door, remove all trays and dish baskets.
• Unscrew the drain filter from below.

• Clean it from blockage by rinsing with running water.
• How to unlock the pump? Use a sponge to remove any remaining water from the pump area.
• Press the pump cover until it clicks, then pull it towards you.

• Inspect the pump for blockage. Wear gloves when cleaning, as the pump could be clogged with glass fragments.

To avoid clogs, clean dishes from food residues before washing. Also use special cleaning products.

The cause of the breakdown can be not only a blockage, but also a breakdown of the pump. How to check it:

• Remove the lower front panel of the machine. To do this, unscrew the fastening screws.
• Lay the machine on its side or lean back.
• It is necessary to measure the resistance at the pump contacts.
• Attach the ohmmeter probes to the pump contacts.
• The device is healthy if the number on the screen is 1000-1500. In other cases, a replacement is needed.

Over time, when using a Siemens machine, the washing quality decreases. You do the usual loading, pour in the detergent, but the dishes at the exit are not too clean. Why is this happening:

1. The water supply pressure is too low.
2. The supply valve is clogged.
3. The holes in the rockers are clogged.

1. Wait until normal water supply resumes.
2. Check the mesh filter for clogging.
3. Clean the detergent drawer after each cycle. Over time, the powder accumulates, dries on the walls, growths block the passage of the valve. Just wipe the tray with a dry cloth after washing the dishes.
4. The dishwasher has two rocker arms for spraying water - upper and lower. Unscrew the top and remove it from the seat.Pull the bottom blade up and out of the housing. Clean the blade holes with a toothpick under running water.

Do not forget to take care of the equipment, then breakdowns will happen less often.

If the indicators on the panel flash randomly, an emergency shutdown occurs, the reason is in the control module. Diagnosing a breakdown of a module, and even more so repairing it, is only possible for a master. The structure of the Siemens dishwasher complicates this task.

The manufacturer enclosed the control board in a soldered block. Most specialists refuse to repair it.

The module is one of the most expensive dishwasher parts. Therefore, if the car is old, it is more profitable to buy new equipment than to change the module.

Carry out independent repairs of equipment only after the end of the warranty period. Use cleaning products, clean the filters in a timely manner. Then you do not have to deal with malfunctions and repair breakdowns at home.

Siemens dishwashers are rightfully considered the most reliable. Quality parts plus excellent European assembly speak for themselves. However, this technique also needs repair. For most, the Siemens machine breaks down after 10 years or more, for some it may break down after a couple of months, but sooner or later it happens. How to repair Siemens dishwashers, what typical malfunctions occur in such dishwashers and whether it is possible to repair such equipment with your own hands, we will talk about this further.

According to data provided by service center specialists, Siemens dishwashers break down about 2 times less often than most budget brands of dishwashers and middle-class brands. But Siemens still has some weaknesses. The most common is considered a malfunction, the main symptom of which is an extremely slow set of water and a periodically freezing dishwashing program, and the choice of program does not matter.

After some time, if the operation of the Siemens dishwasher continues, it will start to give an E16 error, at first occasionally, then more and more often. In the end, the machine will freeze completely, giving an E16 error and restarting will not work. What breakdowns give rise to such symptoms? In essence, there is only one reason - a flow filter in front of the filler valve.

dishwashers Siemens of European assembly are designed for well-purified water with a minimum amount of impurities and suspension, their flow filters have a mesh with very small cells, which quickly clogs when connected to a Russian water supply. In order for the regular filter to be less clogged with dirt, it is necessary to install another cleaning flow filter in front of it, while both filters must be removed and washed once every 6 months.

Important! Experienced craftsmen, in addition to an additional filter, apply another protective measure - they immediately change the standard filter. Recently, the manufacturer began to produce spare parts (including filters) specifically for Eastern Europe and Russia. It is these filters that experts recommend installing when installing the machine with their own hands.

How to resume a normal set of water in the dishwasher and prevent the systematic freezing of the washing program with your own hands, without the help of a specialist?

1. We reliably block the water going to the Siemens dishwasher.
2. We extend the dishwasher so that reliable access to the inlet hose and its connection points is opened. But do everything carefully so as not to pull out or crush the hoses and the power cord.
3. We disconnect the hose together with the additional filter (if any) from the tee tap.
4. We unscrew the hose on the other side of the dishwasher and unscrew the regular filter from there.
5. Wipe the filter seat with a dry, clean, lint-free cloth.
6. Pour lemons into a small basin (100 g per 2 liters of water), pour warm water and soak both filters in this solution for 2-3 hours, then rinse and clean the filters from dirt and install in place along with the hose.

Also, quite often, Siemens dishwashers, after 1-1.5 years of operation, begin to wash dishes worse. At the same time, the user adds the same detergent to the cuvette, in the same amount, also folds the dishes, selects the same washing program, in general, does everything in normal mode, and the washing quality becomes worse. What is the cause of this annoying symptom? Strictly speaking, there are several reasons:

• weak water pressure;
• the detergent supply valve does not work properly;
• clogged rotary rocker nozzles.

Weak water pressure occurs due to the fact that the inlet valve flow filter is clogged.

How to clean it with our own hands, we have already discussed in the previous paragraph. Therefore, we immediately move on to the second reason - the detergent supply valve does not work well.

The essence of the problem is as follows. Powder or tablets Finish for the dishwasher are placed in a special compartment, from where they are taken gradually during the implementation of the washing program. If this compartment is not cleaned and rinsed, then the valve will eventually begin to open and close poorly, and its holes will become clogged with dried residues of a semi-dissolved powder. As a result, during washing, the powder or tablet will dissolve worse, and the quality of dishwashing will only worsen.

The problem is solved simply. It is necessary to make it a rule after each washing of dishes to wipe the detergent drawer with a clean, dry cloth. and then this problem will never visit you again. It is also a good idea to periodically use dishwasher cleaners, which will prevent the accumulation of dirt in the dishwasher and remove any unpleasant odors.

The same thing with clogged Siemens dishwasher rocker nozzles. Once every 4-6 months they must be cleaned, otherwise there will be no water pressure, and the quality of washing will decrease. The nozzles are cleaned with a regular toothpick. Push it alternately into all the holes of the rocker, and then start a blank wash with dishwasher cleaner.

We have considered the malfunctions associated with the reduced quality of washing, now we turn to problems with the removal of waste water. Why can water drain badly from Siemens dishwashers? There are two main reasons: either there was a blockage somewhere in the drain tract, or the pump failed. We have repeatedly considered cleaning the dishwasher from blockages. This process is well described, for example, in the article Replacing and cleaning the dishwasher filter, we will not dwell on this point again.

In general, the dishwasher, like any other technique, must be monitored, if this is not done, imminent breakdowns are inevitable. A pump failure is a much more unpredictable situation. You can keep a good eye on the Siemens dishwasher and still get into a similar situation. You can read how to replace the pump in a dishwasher with your own hands in the article of the same name, it's not too difficult. But first, you need to check the pump, maybe it's not broken, but is it an electrician or electronics?

• We arm ourselves with an ohmmeter and remove the front bottom panel of the Siemens dishwasher.
• We disconnect the machine from the network and tilt it back a little (about 20 0).
• Now we can clearly see the pump mounted on the circulation pump housing, set the minimum value on the ohmmeter, and then install its probes on the pump contacts.
• We measure the value, if the figure is in the range of 1000-1500 - everything is fine, if less, the pump is faulty.

For your information! A faulty pump is not necessarily “silent” while the dishwasher is running. It can hum, but it does not fulfill its function of pumping water.

Another problem with modern models of Siemens dishwashers is a spontaneous emergency shutdown, which is preceded by flashing indicators and beeps. Moreover, if the dishwasher is disconnected from the mains, and then turned on again, the problem repeats, it is completely impossible to wash the dishes. What is the cause of the problem?

Unfortunately, this breakdown is one of those that cannot be fixed by hand. If your car is under warranty, experts advise getting rid of it altogether. The fact is that such symptoms indicate a breakdown of the control module.

At Siemens, repairing the control unit is much more difficult, since the board is soldered by the manufacturer into a non-separable module. For this reason, only some masters undertake to repair it, basically everyone refuses and offers to change the entire unit, and this is almost half the cost of a new dishwasher. If the car is old, then it’s better not to repair it at such a breakdown, although it’s up to you.

In conclusion, we note that Siemens dishwashers are very, very reliable, their malfunctions are largely associated with improper user operation. Therefore, if you take care of your dishwasher, it is very likely that it will work for many years without any failures.
