Damage to the motor windings can also be the cause of the malfunction. To check it, you must turn off its conclusions and check with a multimeter for winding breakage or interturn short circuit. In the event of the mentioned malfunctions, it is necessary to replace it with a similar motor or rewind, which will be carried out by a specialist.
If there is no sound of starting and running the engine, repair of Indesit dishwashers and search for damage must be carried out in the same way as described in the first malfunction, i.e. it is necessary, guided by the diagram, to go along the chain and look for the cause of the break.
It is necessary to check the sewer pipe to see if the drain is clogged. This could be due to a blockage or damage to the drain pump. To determine the cause of the malfunction, it must be removed and checked for clogging. Also, using a multimeter, you can check the health of the windings.
Also, the reason may be dirty filters, how to maintain them is shown in the video below.

The causes of this malfunction can be both damage to the motor windings and a malfunction of the timer. With the latter, everything is not very simple, so if you suspect a timer, contact a repair specialist for dishwashers from Bosch or other manufacturers.
The leakage of the car can be associated with the condition of the door seal, it is checked visually. If his condition is unsatisfactory, then you can buy a new one and replace it with a new one without any problems.
In the event of a leak from under the machine, the location of the leak must be determined. To do this, you need to remove the panel in order to get to the bottom. This will allow you to visually identify the location of the leak, as a rule, it can be a damaged pump seal, water supply hose or in the drain system.
Check for metal or glass debris. Bearing wear possible. If at the same time the quality of dishwashing has decreased, this may indicate damage to the pump impeller. Therefore, if there are no fragments, it will be necessary to disassemble the motor and pump in order to determine the degree of bearing wear. The motor shaft must run smoothly and smoothly without obstruction.
This malfunction can be caused by the following reasons:
the heating element is faulty;
defective temperature sensor;
timer malfunction.
You can figure out the first malfunction yourself, disconnect the heating element and check for resistance. If there is a break, we buy a new one and change it. With the other two it will be quite difficult, for example, to check the timer, you need to know the entire sequence or algorithm for turning on the contacts to heat the heating element. Therefore, the best solution for most users would be to contact a service center.
If the machine is equipped with a turbo-drying system for dishes, then this malfunction indicates damage to the fan motor windings or damage in the switching circuit thereof. It is easy to check the windings, you need to get to the terminals for switching on the fan motor and check their serviceability with a multimeter.If the fan is operational, it is necessary to check the entire electrical circuit for switching on the fan.
We have covered the most common dishwasher malfunctions. Of course, it is impossible to describe everything, but we hope that we have sufficiently highlighted the troubleshooting algorithm so that we can start to repair dishwashers on our own. It is worth mentioning that the repair of Electrolux dishwashers, or any others with your own hands, should be done after the expiration of the warranty period. Otherwise, you void the manufacturer's warranty, but it is definitely up to you to decide.
Krona dishwashers were among the first to appear on the household appliance market. The attitude towards dishwashers of this model among consumers is different: someone speaks positively about their work, and someone does not like them. Still, the Krona dishwasher does not disappear from the shelves, finding its customers.
Dishwasher Krona
Krona manufactures dishwashers in two versions, differing in size, weight and load volume:
dishwasher Krona BDE 4507 EU;
assembly model BDE 6007 EU.
Both options have similar performance characteristics.
The Krona BDE 4507 dishwasher will be a good purchase for a small kitchen. The dimensions of the BDE 4507 EU unit are 44.5x55x82.5 cm, the weight is 33 kg, which significantly saves the usable area of a small kitchen. The dimensions of the BDE 4507 EU dishwasher allow you to simultaneously load 8 full dish sets into it, which is quite enough for a small family.
Due to its relatively large size, it is worth installing the Krona BDE 6007 EU dishwasher in kitchens where there is enough free space. The dimensions of the BDE 6007 EU unit are: 59.5x53.5x82.5 cm, weight 39 kg. At the same time, it is possible to wash a set of dishes for 12 persons.
Dishwashers of the Krona model are easy to install by yourself, following the attached instructions, they are highly efficient, easy to operate, but not very economical. Electricity consumption is 1760 W for the entire dishwashing cycle.
In order for the Krona dishwasher to work for a long time and efficiently, the instructions for using the appliance recommend:
Position the kitchen utensils so that they do not move under the running water.
Place sharp objects (knives, forks) away from the rubber seals of the machine.
Plastic, in order to avoid melting, do not place near heating elements.
Monitor the power cord for good condition. If damage is suspected, do not use the device, but contact the service center for repair.
It happens that the machine stops working correctly, the self-diagnosis system displays an error code. Depending on the code, the Krona dishwashers may need to be repaired at a service center, and some problems can be rectified by yourself. The instructions for the dishwasher tell in detail what errors in the operation of the Krona unit occur most often, and indicate how to solve the problem.
The most common Krona dishwasher error codes are:
E1 indicates that the dishwasher is not getting water well. This can occur due to insufficient water pressure, problems with the filter or water filling valve. If the E1 error is caused by a malfunction of the kapan or filter, it is not necessary to contact the service center - such minor repairs can be done on your own by clearing the clogged places or installing a new spare part, as indicated in the instructions.
E2 - slow drainage of water after washing dishes, the causes of the problem and the methods of elimination are similar to those of E1.
E3 - insufficient water heating to start the program. An error in the operation of E3 can be caused by power surges or a malfunction in the heating elements. Do-it-yourself repairs with the E3 code are undesirable; it is better to contact the service center to diagnose the problem.
E4 is caused by the Krona being overflowing with water. The solution to the problem will be to check the water level sensors and the outlet valve with the subsequent installation of a spare part instead of the damaged one.
E5-E7 are associated with a disruption in the supply of electricity to heating systems. Repair of such damage is possible only in specialized workshops, where they will carry out a full diagnosis and install new parts to replace the damaged ones.
Despite the fact that many modern, economical dishwashers have appeared on the home appliance market, Krona kitchen units are still in demand due to their robustness and ease of use.
KRONA is a German trade mark, under which products are manufactured with an eye to the "golden mean" - good quality at a low cost. Household appliances Krona, including dishwashers, belong to class A in terms of washing quality and meet increased requirements for efficiency. They have all the necessary functionality, look aesthetically pleasing, and work quietly. At the same time, prices for them are on average lower than market prices for dishwashers of a similar level.
Since we, as a service center, deal with household appliances, usually in a negative way, when they fail, our technicians are well aware of the vulnerabilities of products from various manufacturers. And it should be noted that the repair of KRONA dishwashers is quite consistent with the frequency of calls and the causes of breakdowns with the average values for other brands. So to say that the "budgetary" Krona is worse than its more expensive "colleagues in the shop" is not necessary.
However, with KRONA dishwashers periodically:
The pump (pump) breaks down, as a rule, due to blockages in the drain hole;
A strong scale is formed on the heating element, which degrades its performance and further disables it;
Hoses and pipes wear out, leaks begin.
"RemBytTech" specializes in eliminating such and any other problems with household appliances. Our workshops are equipped with special equipment, and the craftsmen have received the necessary training, as well as training with manufacturers. We know how to repair the Krona dishwasher quickly, efficiently and for a long time, therefore we give a guarantee for all types of our work.
In the same way, just as no doctor before examining the patient will talk about the diagnosis, in the event of a breakdown of household appliances, there is no point in discussing the price of restoring its performance before the diagnosis is performed. But for convenience, we suggest that you independently "estimate" the costs according to our price list. As you can see, this is not overly expensive anyway:
Thanks to the electronic control board, the dishwashers have a self-diagnosis system. When a malfunction occurs, the module transmits a malfunction code to the PMM display. If you notice that the Krona dishwasher displays an E1 error on the display, then water does not enter the bunker.
Error code E 1 in Krona models indicates that the waiting time for water intake has expired - it has not been drawn into the tank. For what reasons this happens:
Blockage in the inlet hose, filter, valve.
Intake valve defective.
Actuation of protection against leaks "Aquastop" (in such cases, the code E15 may appear).
Open circuit.
First, rule out a possible network outage, try to reset the error:
Unplug the machine.
Wait 15-20 minutes.
Try starting again. Are the icons on the screen? You need to look for a problem.
You have loaded the dishes, started the washing cycle. Water began to flow through the pipes, but did not get inside, or a very small amount accumulated. What to do, how to fix the problem?
Small debris and rust penetrate from the sewer into the system, which clog the parts. Start by checking the hose:
Shut off the water supply.
Unscrew the hose from the PMM body.
Take a look inside. If there is a blockage, flush it under pressure from the tap.
Then inspect the mesh filter. Wash it too, and in case of stubborn dirt, soak it in a citric acid solution.
If no blockage is found, proceed to check the functionality of the element.
Additionally, you need to check its wiring. The control board sends a signal to the valve about water intake, its membrane opens and allows the flow. But if the wiring is broken, then the signal will not reach its destination. How to fix the situation? The train needs to be replaced.
To test the valve, apply an operating voltage of 220 volts to its coil. Does the membrane open? This means that the element is working.
The electronic part can be checked with a multimeter. Apply the test leads to the pins of the part. The working element should show from 2 to 4 kΩ. If broken, install a new part.
The inlet hoses are often equipped with a mechanical Aquastop. Inside there is an absorbent sponge, which, if it leaks, absorbs water and shuts off the supply. In this case, only the replacement of the part will help.
Now you know why the Krona dishwasher can show the E1 icons on the screen. Use our instructions, do it yourself.
Before you start doing dishwasher repair yourself, try evaluating the error code. Intelligent models are equipped with a display that displays mnemonics, deciphered according to the instructions or information on the official website of the manufacturer. Conceived the repair of Crohn's dishwashers. The internal arrangement differs in little things, but a dishwasher will not be a hassle for someone who knows how to fix a washing machine. Study the portal.
The dishwasher is formed by a standard set of parts; models differ from each other by additional options. We avoid touching some sensors, like the Aqua Sensor, that evaluate the transparency of water (fuzzy logic algorithms). The nuances are so subtle that testing on site is hardly possible. The dishwasher includes:
Rocker arms through which jets of water wash the dishes.
The main pump with a pipe that creates a head.
Heating element, sometimes flowing.
Dirty water drainage pump.
Main filter at the bottom of the working compartment.
Salt compartment at the bottom of the working compartment.
Compartment with rinse aid on the door.
Detergent dispenser.
Inlet valve.
A coarse filter at the point where the inlet hose meets the body.
Inlet hose.
Drain hose.
Water is drawn in by an inlet valve, heated, if necessary, by a heating element, which can constructively be part of a recirculation pump. Water, bypassing the rocker arms, sprinkles the dishes, while simultaneously making the blades rotate by means of jet thrust. The dirt is collected in the bottom of the compartment, filtered by two filters, coarse (in the form of a cylinder) and fine (steel mesh). If necessary, the water passes the second circle, or is discharged by the drainage pump into the sewer.
The following are added as needed:
powder for chemical cleaning of pollution;
salt to soften water;
rinse aid to reduce the surface tension of the water, simplifies the subsequent drying process.
The first step is to check if there is water in the riser. Let's open the kitchen tap. In the order of the water supply - the further course of action is determined by the design of Aquastop.
We checked the hose. Turn off the tap, disconnect the dishwasher from the riser. Take a bigger bucket, time it. An open tap dispenses 10 liters of water or more in one minute. Otherwise, the dishwasher may not work. If the components described are functional, check the inlet filler. Disconnect the water supply hose (if available). In this place there is a filter, usually a plastic one.
By the way, if you see signs of a leak, but the hose is in good condition, then in some cases the picture makes it possible to identify a breakdown of the float valve that fixes water where there is no liquid. Easily checked by disconnecting the hose from the machine. But they are not sure that the solenoid valve will be open at rest (depending on the design). You can better learn more from a dealer, a neighbor, who has a similar hose, only in good condition.
The next step is to check the intake valve. The assembly follows the coarse filter washed above.
Every dishwasher repair technician knows where to find one. It is difficult to give specific advice on testing. On most models, the valve is locked at rest. At least that's the case for Bosch.
Meet the case when the float sensor of the internal water intake tank is faulty. The forum discussed the repair of Kaiser dishwashers. The breakdown was expressed by the absence of the control voltage of the intake valve. No error was displayed on the screen. The dishwasher just worked ... but no water.
Defective, finally, may be the electronics filling the opening of the valve, an expert will probably be needed.
First of all, it is worth checking that water is not flowing to all rocker arms. Rarely, but we find that the holes are simply clogged. Then you can remove the rocker using an ordinary toothpick and clean it. Otherwise, there are two options:
The recirculation pump has broken.
The water level sensor of the internal tank with the heating element is faulty, if any. Bosch dishwashers use an instantaneous heater. There is no level meter. There is a vane-type flowmeter, even if it breaks, water will be supplied.
Repair is difficult at home. It happens that the rocker arms refuse to rotate. The reason is trivial enough at times. Plainly loaded dishes get in the way, mechanically blocking the path. Stop the cycle by placing the utensils in a different order. The upper rocker arm will occasionally jam firmly if the threads are not tightened properly. Stop the dishwasher, unscrew the spray arm, reinstall. Rotate by hand to sample. In this case, repairing dishwashers at home is not difficult.
When the result of washing or drying is unsatisfactory, look for the answer in the instruction manual, we will not refrain from a couple of useful tips:
If any lumps of food remain on the plates, try to remember how long the dishes were left on before the cycle. If the dirt is dry, use pre-soak (which is not washing). Use the programs as intended.
It happens that the detergent remains in the dispenser. The assumption arises: the dishes have blocked the lid on the inner side of the door. Just arrange the utensils differently, visually figuring out where the powder tray goes.
Finally, not all dishwashers are designed to use 3 in 1, 4 in 1, 5 in 1. Read the instructions carefully using the tablet.

Water refuses to leave the working compartment - the bottom filter is probably clogged. Unscrew the cylinder, rinse thoroughly under the tap with a brush. It happens that the drain pump has failed. Repairing professional dishwashers will require a call from a professional.
The water remains cold, the washing result will be disgusting, the dishes will leave the compartment wet and cold. The heating element cannot be changed at home. It can only be done by a person for whom the repair of washing machines and dishwashers is not difficult. There is no need for an expert to read this review.

Water wetted the floor - the reason was the loose insulation of the door perimeter. Filling the sump will trigger the anti-leakage subsystem, and the water intake will stop. At the same time, the drain pump will hum, pumping the flood down the drain. The problem is tricky, and you may need to check with your dealer for a new rubber seal. Those who wish are free to try to apply a non-hazardous (non-toxic) sealant to the dishwasher. For example, aquarium.
