No matter how carefully we treat household appliances and equipment, they all tend to break. And, as a rule, this happens at the most inopportune moment. Among other “household helpers,” dishwashers are often used. Depending on the manufacturer, operating conditions and proper use, the equipment lasts for the prescribed period or even longer. A number of reasons can cause a breakdown, as indicated by the device. So, for example, the main errors of the Korting dishwasher consist in the supply or drainage of water, failure of sensors.
Reasons for device malfunction
The main factor in failure is time. Despite the fact that the declared service life of a machine is on average 7-10 years, you can see the error code on the display much earlier. If this happens during the warranty period, the service center will send a specialist to repair it, otherwise the repair will fall on the shoulders of the owners.
Any dishwasher has a “weak spot”, as a rule, it is connected with the water supply pump. The fact is that its hardness is quite high, the presence of impurities and chlorine weakens and clogs the parts of the dishwasher. Power outages cause malfunctions in the electronics of the machine.
Manufacturers' warranties allow owners not to worry about repairs and continued serviceability of the dishwasher. But any user will need to decipher the codes. To explain the reasons for a breakdown or repair if the warranty period has expired, you should present the scale of the problem that has arisen and how to eliminate it. If the error is in the supply of washer mixture, then most likely you can fix it yourself.
We are looking for the cause of the problems
After disassembling the machine, collect all leaked water with rags in a bucket and begin inspection. If you find that the hose connecting the pipes to the pump has fallen off, loosen the clamp securing it on the back side and inspect the hose from the inside.
Pumping system with aquastop
It often happens that the reason the hose comes off is a critical level of pressure. This may be caused by a blockage in the hose itself or at the place where it connects to the pipes. This can be caused by various types of blockages. For example, scale - residues of mineral salts and other chemical elements settling inside the machine. Over time, the salts harden and can form a solid barrier. This can lead to failure of the entire drainage system, so it is best to take preventive measures - add special salts to soften hard water when starting the dishwasher. Otherwise, this may lead to a major breakdown that cannot be fixed on your own, and you may have to purchase a new dishwasher.
The second possible cause of problems recognized by the system under code e4 is a leak in one of the pipes or hoses in the drainage system. It can leak at the junction of hoses and pipes, or from holes in the body. In the first case, you just need to re-tighten the clamps or change the rubber gaskets, which are commercially available in plumbing stores. If you find a leak on the body, then you will have to replace the spare parts. Do not tighten it with tape or tape - this can lead to more serious problems in the future.
Dishwasher Korting
The German brand has long been famous for its reliability and durability. Functionality and the ability to multitask are the qualities that have been appreciated on the Russian market. Users of Corting dishwashers note their reliability and full compliance with the characteristics of the device declared by the manufacturer.
New models have a convenient interface that gives the user hints about errors in operation. As soon as the machine stops functioning properly or the water pressure is not good enough for it to work, the voltage is weak, then the screen shows an error.
The operating instructions for the machine will tell you what the information on the monitor means and what to do with it. Typically, with reliable Korting technology, you don't have to worry about replacing key components. But there are errors that should be corrected in a workshop or by calling a specialist to your home.
All Korting dishwashers have a similar error indicator. If the model is an older model, without a panel, then the device will inform the owner about the problem by quickly flashing the LED light opposite any of the function start buttons.
It is worth noting that the machine will only notify you about problems that the owner can handle on his own. In other, more complex cases of errors in work, only a knowledgeable person can deal with them. Information about incorrect operation can only be obtained by typing a certain combination on the display buttons.
Features of the Corting technique
One of the most popular brands of household appliances is the German Korting. The company has been operating in this segment for more than 125 years, producing products on modern equipment with a multi-stage quality control system.
Built-in equipment is mainly produced under the Korting brand:
- Ovens;
- Hobs;
- Hoods;
- Dishwashers;
- Freezers and refrigerators;
- Microwave ovens;
- Washing machines.
But the range also includes free-standing devices.
Error code and its interpretation
So, what to do if there is a slight collapse in the work of your favorite “assistant”? The first step is to reset the error. To do this, simply disconnect the machine from the power supply. This will reboot the device and allow it to clear the error code.
If the machine does not reboot and does not reset the error, then you need to contact the service. Before eliminating an obvious malfunction, specialists will analyze the operation of the device as a whole.
The four main error codes for Korting machines, signaling problems in the operation of the unit, are described in the instructions for the equipment. It is possible to cope with the error and fix the problem yourself if you have the skills to use tools.
Code E1 appeared on the display - this error means that the chamber of the Korting machine will not be able to fill with hot water due to the lack of liquid supply to the system. The reason may be an incorrect connection, a broken water level sensor, errors in the electrical wiring, or a malfunction of the digital plateau.
What to do if such an error occurs? First you need to check whether there is water in the system; the city authorities could simply turn it off during maintenance work, or the supply valve is closed directly at the connection point of the machine. There may be a blockage in the inlet filter. In this case, you should remove the weed plug yourself by unscrewing the hose from the housing and rinsing the filter under running water.
Do not rule out that the machine is connected incorrectly if this is the first time it is turned on. Kinked and pinched hoses will not be able to supply enough water, which will inevitably cause a malfunction signal.
Code E2 is an error warning that it is impossible to drain waste water. The Korting dishwasher indicates one of the problems:
- incorrect, twisted position of the drain hose, possible bending;
- clogged drainage filter: to avoid this, you should clean the dishes from solid food residues, napkins, etc.;
- drain pump malfunction;
- pump clogged;
- the code also appears when the pressure switch or triac system burns out, which should be replaced;
Before troubleshooting problems yourself, you must disconnect the machine from the power source and water supply. Flushing the drain hose and cleaning the filter are perhaps the only measures to eliminate the error. But, besides this, you need to make sure that the wiring of the machine is working properly using a multimeter. Some of the recommendations cannot be carried out with the ability to handle tools, for example, to clean the pump you need to disassemble the machine body.
The E4 code signal warns that the Korting dishwasher does not detect the water supply and is overflowing. Most likely, the float sensor failed, which caused the Aquastop system to activate. Measures to eliminate the error will include replacing worn-out pipes and gaskets, changing the sealing rubber, and diagnosing the machine’s fluid fill sensor. Also, special attention should be paid to the condition of the water supply hoses.
E8 - an error code for the flow sensor or its breakdown occurs if the machine does not perform its functions at full capacity. The reasons may be burnt out wiring, control module or broken wire connections. Also, blocking the rotation of the spray arm with dishes inside the chamber displays the E8 code on the display. Repair work consists of replacing the wiring and control module, checking the insulation inside the dishwasher.
How to determine an error if there is no code displayed on the display
Basic built-in models, for example KDI 6040 or KDI 4540, have a character display and indicators that indicate errors.
Codes | Values | Possible reasons | Elimination |
The quick wash indicator is flashing | Water does not flow or flows too slowly into the cooking chamber. | Valves are closed, low water pressure in the water supply. | Check the water shutoff levers. |
The quick wash indicators and the “90 min” mode flash at the same time. | Heating element malfunction. | The heater has burned out. | Contact the service center. |
The Economy Program (ECO) indicator blinks. | Overflow. | The leakage protection system has activated. | Turn off the device. Call a service specialist. |
Repairs of medium complexity
Repairs of medium complexity are considered to be manipulations that require partial disassembly of components or a frame - the dismantling of one or several panels.
The video below shows the process of replacing the turbidity valve. The video is also useful in that it examines in detail the dismantling of the machine from its installation site and its removal from the niche for further manipulations.
Repairs of medium complexity include troubleshooting dishwasher door components.
If the car cannot function properly due to a broken door lock, it will need to be repaired and, in some cases, replaced. In order to get to the door lock, you will have to disassemble the front panel. To learn how to replace the door locking mechanism, watch the video.
If your dishwasher is decorated with the same façade as the rest of your kitchen furniture, the door cables may not be able to withstand the additional weight and may break. The following video explains their replacement.
If the door is difficult to open or close, there may be a problem with the hinges. To learn how to replace a hinge or hinge spring, watch the video.
The fault may affect the water filling system. The design of the system can be different and operate on parameters: pressure, time or flow. The filling system, which is pressure activated, has a diaphragm that closes the contactor. Over time, due to hard water, dirt and lime deposits, the diaphragm loses its ability to close the contactor and this element must be cleaned or replaced.
A reed switch-based system (meter, flow meter) is very sensitive to an increase in water pressure in the main line and can issue incorrect filling commands. If an error code “failure in the system” is issued, the sensor needs to be replaced, and if the blades jam, only repairs at a service center or replacement of the unit will help.
How to fix the problem
Before troubleshooting, rule out a system failure. To reset icons from the screen, do this:
- pull out the PMM plug from the socket;
- After 10-15 minutes, reconnect.
If this doesn't help, inspect the parts.
Check the intake valve.
It is usually located at the bottom of the case:
- close the shut-off valve;
- disconnect the inlet hose - be careful, water may flow from it;
- there is a valve behind it - look to see if its contacts are burnt;
- check the mechanical part by applying an operating voltage of 220 V to the coils of the part. Does the membrane open and close? This means the element is working.
In the event of a breakdown, the membrane is stuck in the open position, so water flows without stopping.
In the event of a malfunction, complete replacement of the valve will help.
To do this, disconnect the wiring chips and unscrew the fastening bolt. With the old element, you can go to the store to find a suitable replacement. Installation is carried out in reverse order.
To diagnose the pressure switch, you will have to disassemble the car.
In Bosch and Siemens models, it is connected to the circulation pump. Therefore, the approach to the part is carried out through the bottom of the equipment.
We wrote about how to replace a level sensor in a separate publication. The check is simple: inspect the wiring. If there is a malfunction, the sensor must be replaced.
Do not be alarmed when you notice error E 4 on the Krona dishwasher screen. Now you have the meaning and decoding of the code - you can fix the problem yourself.
Possible malfunctions of the Korting KDI 4550 dishwasher:
- The whole car is flashing!
- The machine makes noise, the machine rattles, the machine vibrates. Extraneous sound in the machine
- The machine takes a long time to wash
- The dishwasher is leaking
- The smell of burning
- Dishwasher won't turn on
- Dishwasher does not fill with water
Simple repairs that do not require professional skills
Let's look at problems that can be fixed without involving specialists. Almost all of them are caused by blockages in various components. The blockage can be external or internal.
Removing external blockages
The cause of an external blockage may be in the drain. If water leaves at all drain points with noticeable difficulty, then this problem needs to be solved by mechanical or chemical cleaning of the siphon and sewer pipes. A blockage can also occur in the hoses. They can be twisted, bent, pinched - in this case they need to be straightened. If they are covered with limescale from hard water, you need to disconnect them from the machine and clean them.
Correct connection of the drain to the sewer
Removing internal blockages
The internal blockage is concentrated:
Removing the internal filter If the machine has stopped with water inside, you need to click on “Drain” and wait until the chamber is empty and disconnect the unit from the network. The remaining water must be removed with a sponge. Do not remove dirt with your bare hands unless you are sure that there are no glass shards in the dirt.
Since the arrangement of elements differs in different designs, it is necessary to study the operating instructions (service book, passport). Find the attachment points of filters or other components, and, armed with a screwdriver, tweezers, wrench, pliers or other suitable tool, get to the clogged part, remove it and clean and rinse it well, and then put it back in place.
Video about replacing filters using the example of a Hotpoint dishwasher
When using a detergent with a high foaming coefficient, water may enter the tray, which will lead to the activation of the “aquastop”. The water from the pan must be removed. If you cannot get to it yourself, then simply do not use the machine for a while: the water will dry up and the machine will work normally.
Checking electrical contacts
If the car engine does not start, you need to check the fuse and switch on the electrical panel, as well as the integrity of the electrical wiring. When replacing a fuse, you must select a part similar to the one being removed.
If this is not the problem, you need to evaluate the condition of the contacts in the junction box, which is usually located under the protective shield. Power is supplied to the machine through clamps, which can fail due to vibration and moisture. The reason for the lack of power may be in the terminal box. The contacts must be cleaned of rust with sandpaper and the clamps must be reinstalled.
Troubleshooting technique
We have just described the errors of the Corting dishwasher and deciphered them. One really gets the impression that the self-diagnosis system is limited. To be honest, it doesn’t even cover 25% of all possible dishwasher malfunctions, and what should you do if something breaks in the Corting machine that is not indicated by an error code? The answer is simple, you need to watch and listen to how the machine works and trust common sense.
Suppose the thermistor or heating element is broken. There is no error code for these breakdowns in the Corting self-diagnosis system, which means the machine will continue to work no matter what. Pay attention to the quality of dishwashing and what kind of water it is washed with. Surely you will understand that washing is carried out in cold water, but after that you can take measures to check the heating element and thermistor.
If, for example, water has accumulated in the washing chamber of the machine and does not flow into the system, the Korting dishwasher may stop working, but not display any error. How to fix this? You need to turn off the machine, drain the water, and then unscrew and clean the garbage filter. It is the blockage in this filter that prevents water from circulating normally.
In general, we will not list all possible defects of the Corting dishwasher; this is the topic of a separate publication. Our main task is to show that even without a self-diagnosis system, defects in a dishwasher can be recognized, but if the system helps us, then this is only a plus.
