What should I do if the washing machine does not respond to a button press? In the article we will provide step by step instructions, tell you whether you can repair or replace the buttons with your own hands.
Electronics washing machine - the most vulnerable part. This applies to the control panel and the buttons on it. The keys are constantly exposed to the user, they fall on the powder, rinse, which leads to failure in work.
Causes and symptoms of failure
How to determine the cause of the problem by external signs:
- The start button does not turn on. When you click the car does not respond.
- Pressing the “Start” button causes the LED to light up, nothing happens next.
- When you select the "On / Off" button, all the lights flash.
Why the buttons do not work:
- A strong impact on the buttons leads to the fact that over time they sink.
- The detergent on the panel may cause a breakdown. As a result, the keys stick.
- Broken contacts leading from the electronic board to the buttons.
Pay attention! If after the purchase and installation of the washing machine the power button does not work, the reason is in the factory defect. Contact the warranty service.
Most often, the buttons that are frequently affected are broken. These are the Start, Pause, and Program buttons. Also, the rotary selector fails.
Diagnostics of malfunctions, their elimination
Disconnect the machine from the network and communications before looking for the cause of the malfunction. Begin testing with the simplest element, which does not require disassembly of the machine.
Voltage problems
It happens that you try to run the washer, but nothing happens. It is not necessary to immediately contact the service, maybe your electricity is turned off. In this case, you just need to wait for it to resume.
In the network itself there are also power surges. If the voltage level is too low or vice versa exceeds 220 volts, then the washing machine will not work. To test a guess, take a multimeter, set the dial to voltage measurement mode. Attach one probe to the COM socket in the socket, the other to the VΩmA socket.
Keep in mind! Network problems may arise if your neighbors use high-powered equipment.
If you find problems on the network, then an electrician will need help.
Faulty extension cord
It is recommended to connect the washing machine directly to the network. But if you use an extension cord, choose a quality device with overload protection.
Carefully inspect the wiring at the time of burnout or molten plastic. If outwardly everything is in order, connect another device( lamp, charging) through an extension cord and check its operation. If the device does not work, replace the adapter.
Unlocked hatch lock
If the door is not locked, the wash will not start, as there is a risk of water leakage. Try to press the door tightly - if it does not come out, the lock may be broken. In this case, check the hole in which the tongue enters. Perhaps there was trash buried there.
Also check the lock itself:
- Open the door.
- Remove the two bolts that secure the lock UBL.
- Bend the sealing rubber of the hatch and remove the clamp.
- Pass the arm over the case, remove the lock and disconnect the wiring.
You can check the lock with a multimeter. We wrote more about this in previous articles. If there is a malfunction, the part cannot be repaired, a complete replacement is necessary.
The
noise suppression filter does not work. Since the washing machine is a powerful device, its design includes an FPS filter that suppresses interference. Thanks to him, other appliances in the kitchen( TV, radio) are not interfered.
You can test the operation of the filter as follows:
- Disconnect the washer from the power supply.
- Remove the two bolts that secure the top cover.
- Slide it away from you and remove it from the case.
- At the wall in the corner you will notice a filter. It looks like this:
- Inspect the wiring and the surface of the part. As a result of a voltage surge, the filter could swell, and the wires melt, burn.
- After unplugging the wiring and unscrewing the fastening screw, remove the filter from the housing.
- Contacts FPL are called a multimeter.
The power button on the washing machine does not work.
From the noise filter, wiring leads directly to the Start button. Without closing the top cover, check the button contacts. If outwardly there is no damage, ring the two wires with a multimeter - phase and zero. To do this, turn on the button to understand whether it connects the contact or not.
Such a wiring device - from the filter to the "Start" button - is typical of early brands of washing machines. In modern models, wiring leads directly to the control module. Therefore, the following is checked electronic unit.
The
control board is faulty. Testing the command device is not an easy task. Independently it is better not to do this. All elements and contacts of the board are checked by a multimeter in a certain order. Therefore, if there is a suspicion of its failure, contact the service center.
The machine does not react at all to pressing the buttons of the
. What if there are no keys on the panel except the “Enable / Disable” button? Did all the buttons break? Not. Most likely, the “Protection against children” was installed.
Disconnecting the machine from the network does not help unlock. It is necessary to simultaneously press the "Spin" and "Function".Make sure the lock is no longer displayed on the display.
What to do if the
sensor does not work If the touch buttons on the panel of the Ariston, LG and other models do not work, then they need a complete replacement. You can purchase a touch panel separately and install it in place of the old one.
Most often, the sensors fail due to high humidity in the room or in contact with liquid detergents. It is advisable not to install such equipment in the bathroom, since its electronics are very “delicate”.
How to replace the buttons of the washing machine
Can I do the replacement of the buttons of the washing machine with my own hands, or do I have to call the wizard? The answer is simple - you can. Act sequentially:
- Before starting work, unplug the washer from the mains.
- Need to remove the dosing tray. Pull it towards you while simultaneously pressing the latch in the center.
- . Unscrew the screws from the back, move the top cover away from you and set aside.
- Unscrew the screws that are located behind the dosing tray.
- If there are screws on the other side of the panel, unscrew them.
- Unclip the plastic latches using a flat-head screwdriver.
- Before disconnecting the wiring, take a picture of the location of the connectors. So you can connect them correctly.
- Removing the panel from the case, you will see its components. This is the body of the panel and the control unit, which is mounted on the latches.
- After opening the latches, set the control board aside.
- Now you can see the buttons.
- All keys and the selector are removed by simply pressing from the outside, so changing them is not difficult. The design is very simple, the buttons just click on certain areas of the board. Therefore, the fee is checked on a mandatory basis.
After removing old items, install new ones. To do this, you need only hands and a screwdriver. Then the electronic module is put in place, the latches snap into place and the wiring is connected.
If during disassembly you find that rubbish, powder, gel have got into the connectors of the buttons, try to clean them and check them again. May not have to purchase new parts.
Is it necessary to repair the
control panel? Before fixing the panel, you wondered: is it necessary to change all the elements due to one button? The question is which key is not functional.
- If the start button does not work, you will not be able to turn on the washing program - repair is required.
- The rotary selector does not work - you will not be able to switch the program and wash certain types of things. And if the temperature switch is broken, the quality of washing will drop dramatically.
Of course, if a button that is rarely used or not used at all is defective, then you can try further exploitation of the washer. However, it is dangerous. After all, the reason may be a malfunction of the site of the module or contacts. Therefore, it is recommended not to delay the repair.
In some cases, the self-diagnosis system of the washing machine may display a fault code on the display. For example, if a module breaks down. Then you need to know the meaning of the code and take appropriate action.
Replacing the buttons on the panel is not difficult with your own hands. But when it comes to electronics - use the services of professionals.
