A dishwasher, like any other electronics, can have various problems associated not only with the start of the device or the work process, but even with the shutdown.
However, most often problems arise precisely in the process of work, and separately we can single out the issue of machine freezing during operation.
Find out what reasons may not work dishwasher the car can also following the link.
The washing program does not start. The car does not turn off
In some situations, the dishwasher after turning on may not respond to commands and other user actions. At the same time, it is not even possible to turn off the machine by pressing the appropriate button.
All this indicates that the control panel is faulty. The most likely is that a problem has been detected with the contacts of the buttons or with one of the control triacs. Do not rush to call the wizard, because in most cases, you can solve the problem yourself.
In order to check and replace the triac, the user will need basic knowledge of the principle of operation of semiconductor circuits, as well as the ability to handle a multimeter and a soldering iron. Interested make repair manipulations with the dishwasher with your own handswill be able to do this according to the following list of actions:
- Multimeter setup. The device turns on and sets to voltmeter mode, then the minimum value in volts is set. Next, the probes of the multimeter are closed to each other, and the operation of the device is checked.
- Removing the control board: When the dishwasher is switched off, open its door. At the ends and on the inside there are fasteners that need to be unscrewed. After that, the inner part of the door can be removed and exposes the desired control board.
- Fixing the control board. Having found the required triacs on the control board, it is necessary to check their serviceability with a multimeter in turn. After detecting a defective component, it will need to be unsoldered and removed. Taking the extracted part for the sample, you should purchase a similar one for subsequent replacement.
- Soldering. Carefully, in order not to damage the tracks, it is necessary to solder a new part instead of the old one.
For those who perform such an operation for the first time, you should focus on the photo above, where the arrow indicates one of the triacs.
The washing program is stuck
During the operation of the dishwasher various errors may occur, and the most common problem is the freezing of the washing program. As a result, the user may need to restart the dishwasher. Most errors have their own codes (e.g. i30 error code, e4, e03, e09 and others), the interpretation of which can be easily found in the manual, and brief information is displayed directly on the screen.
System malfunctions are described in the program of the control module, this includes the program of the popular Bosch dishwasher. This allows self-diagnosis and alerts the user about various problems. Often, the error that occurs does not disappear, even if the device restarts or turns off, and then turns on. The only solution to this problem is to determine the cause and its complete elimination.
A program freeze error can be caused by a variety of reasons. However, this often happens when the user does not perform regular cleaning and maintenance. As a result, the filters may become clogged, then sensors are triggered, and the control module can block the operation of all components of the machine. This will continue until the blockage is completely eliminated.
It happens that a certain number of errors of various types accumulate during operation. They are insignificant and do not interfere with operation, but after a certain time the machine may start to malfunction or fail to start at the first attempt, which is fraught with serious breakdowns in the future.
Those who are wondering how to reset the accumulated errors should press a certain combination of buttons and perform some actions.
First, the user opens the door of the dishwasher and turns on the device itself. Then at the same time, the program buttons 1 + 3 are pressed and held for three seconds, and then the door closes. Then the door opens again, and the dishwasher is turned off, then turned on again. Now the reset button is pressed and held for three seconds. The door closes again and the user waits for the signal to finish washing. After receiving the signal, the door opens and the car turns off.
Typical malfunctions
Many problems in the operation of the dishwasher in the event of a complication of the situation result in serious malfunctions. Most of them can be avoided and prevented. It will be necessary to carry out not only regular preventive maintenance, but also fully comply with the operating rules, safety precautions, as well as the requirements for installing and configuring such equipment.
In the case when all conditions are met, but the machine still gives an error, then the case may affect one of the characteristic malfunctions inherent in dishwashers.
There are several typical situations:
- The machine does not turn on. First of all, check whether water and power are supplied to the machine. The circuit may have been broken during a short circuit with the circuit breaker. You can also remove the cord from the outlet for thirty seconds and reinsert it by turning on the dishwasher.
- The appearance of water under the machine. The reason for this phenomenon may be damage to the discharge or drain hose, excess of the permissible water level, malfunction of the lower spray. Also, a banal skew when installing the machine can be a cause of leakage.
- The dishes are poorly washed. So, the holes in the sprinklers are clogged, and cleaning is required.
- Water does not heat up. It is possible that the heater has burned out or that the control board is failing.
- Loud noise at work. This is a sign of improper installation of the machine or the result of wear of the pump.
- The dishes are not dried. Most likely, the dishes were folded incorrectly and too close to each other.
Prevention
Any equipment, including a dishwasher, may have irregularities in its work. It can be either software malfunctions or technical malfunctions. To prevent most of these troubles, the user should be regularly prevented. This implies the following steps:
- It is recommended that you always check the temperature of the inlet water. The optimal value is 50 ° -60 °;
- Necessary monitor the amount of rinse aid in the dishwasher and not allow his shortage;
- Regular filter cleaning is required;
- Observe the rules of operation, including the principles of the arrangement of dishes;
- Protecting the dishwasher from power surges;
- To prevent the occurrence of unpleasant odors inside the machine, the door should be left half open.
Some work should be done with the machine completely disconnected from power and water supply.This will ensure the safety of the user, and is also confirmed by the requirement of service rules.
Error coding and their varieties
Modern types of dishwashers are characterized by increased functionality, including the ability to self-diagnosis. This is a useful feature that helps prevent most serious breakdowns. Focusing on alerts in the form of error codes, the user can directly monitor the status of the machine directly from the device’s display, for example, by establishing that the dishwasher does not end the program.
Each error has its own meaning and description. There are several general categories by which errors are classified:
- Problems with heating water (e.g. error e03);
- Malfunction in the process of draining and filling water;
- Malfunctions with a water switch and sensors;
- Electrical problems.
By deciphering the error code in a timely manner and reacting, the user can eliminate most of the problems on their own, without involving the master and significant financial costs.
Conclusion
Using the recommendations from this article, now every user knows how to properly reboot their dishwasher, maintain it and carry out preventive maintenance.
