If you decide that the electronic board of the washing machine is faulty, you need to pinpoint the breakdown. This can be done by testing and calling. If the checks have confirmed that the reasons for the failure of the washing machine are hidden in the main unit, the firmware of the washing machine modules will help. How to do this will be discussed in our article.
We carry out preparatory work
How to reflash a washing machine yourself? For this work, you need to buy a special programmer that will allow you to connect the control unit to the computer. Carefully inspect the connectors of the laptop or computer to which you will be connecting. The selected programmer must match the connector type: LPT, COM and USB.
It is recommended to choose a branded adapter. For example, for an Arcadia-type module, a USBDM Memory Dump programmer is suitable. Some craftsmen assemble such an adapter on their own, but this is not the best way out. Why?
- It is difficult to find software for home-made equipment. But each proprietary programmer comes with appropriate software.
- The original equipment will definitely work.
- If we compare the cost of assembly and purchase of a new product, the difference is small. Therefore, do not waste time in vain, purchase a quality product.
An ordinary programmer for a one-time firmware of washing machines costs from 150 rubles. Professional equipment will cost 1500-3500 rubles.
If you need to do rotational firmware once with your own hands, then take a simpler product. A conventional programmer is easier to assemble, it does not have fancy controls. But in work it is also effective, like a more expensive product.
Where to find the firmware
The program for flashing washing machines is downloaded on special sites. If you order a programmer from an online store, a program may come with it. You can also find it on the website of the manufacturers of components for your SMA model.
Enter in the search box the query “download the program for flashing the machine (indicate the make and model)”.
Next, consider how to flash the machine yourself through a laptop.
How to flash a washing machine: step by step instructions
To work, you need to remove the control board from the washing machine. Before dismantling, be sure to disconnect the CM from the mains. Follow these steps:
- Open the detergent dispenser. Press the latch in the center and pull the tray towards you at the same time. After removing the dispenser, unscrew the bolts that are behind it.
- Loosen the screws on the opposite side of the control panel.
- Use a flathead screwdriver to pry out the plastic latches on the panel.
- Take a picture of the position of the connectors on the block and unfasten them.
- In order to remove the unit itself, you need to unfasten the latches that secure it to the panel.
Now about how to flash the control module of the washing machine. Connect one side of the programmer to the computer connector, the other to the electronic board.
Download the firmware program that you found earlier, as well as the drivers, to the programmer. Then check if the computer recognizes the connected USB. To do this, click on the “Start” tab, select “Control Panel” and “Device Manager” there.
Now you need to open the program and select the “USBDM” tab. If the computer recognizes the connection, the name of the programmer will be displayed in the tab. To determine if the control board is recognized, click on the “Target” tab. In the selected “Device Selection” section, the board number should appear. If you find it, you can proceed to further actions. How to reprogram a washing machine:
- Select the “Target” tab. To download the firmware, click on the “Load Hex Files” section.
- After the file is downloaded, you need to run the program. To do this, select “Program Flash” and wait until the end of the process. If during the work no errors were displayed, it means that you have successfully completed the firmware of the CM module.
What should I do if the electronic module is not recognized by the programmer? Most likely the problem is with the board. It is necessary to ring all the parts one by one with a multimeter tester. If a malfunction is detected, repair is needed, so it is better to contact the service center. It is not recommended to repair the board on your own. Knowing how to flash the car yourself, you can determine the reasonableness of such a repair.
