If you decide that the electronic board of the washing machine is faulty, you need to accurately determine the breakdown. This can be done by testing and dialing. If the checks confirm 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 on the laptop or computer to which you are connecting. The selected programmer must match the type of connector: LPT, COM, and USB.
It is recommended to choose a proprietary adapter. For example, a USBDM Memory Dump programmer is suitable for a module of the Arcadia type. Some masters assemble such an adapter on their own, but this is not the best solution. Why?
- It is difficult to pick up software for homemade equipment. But for each proprietary programmer is the appropriate software.
- 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 quality goods.
The usual programmer for a single firmware washing machines costs from 150 rubles. Professional equipment will cost 1500-3500 rubles.
If you need to do rotational firmware with your own hands once, then take the product easier. The usual programmer is easier to build, it does not have tricked out controls. But in work, it is as effective as 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 in an online store, a program may go to it. You can also find it on the website of component manufacturers for your CMA model.
Enter in the search line the query “download the program for the firmware of the machine (specify 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 network. Follow these steps:
- Open the detergent drawer. Press the latch in the center and simultaneously pull the tray toward you. Having taken out the batcher, unscrew the bolts which are behind it.
- Remove the bolts from the opposite side of the control panel.
- Unscrew the plastic latches of the panel with a flat screwdriver.
- Take a picture of the position of the connectors on the unit and unfasten them.
- In order to remove the unit itself, you need to unfasten the latches that attach 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 tab displays the name of the programmer. 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 with further actions. How to reprogram the 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 operation no errors were displayed, it means that you have successfully completed the firmware of the CM module.
What to do if the electronic module is not recognized by the programmer? Most likely, the problem is in the board. It is necessary to alternately ring all the details with a tester with a multimeter. If a malfunction is found, repairs are needed, so it is best to contact a service center. It is not recommended to repair the board yourself. Knowing how to flash the machine yourself, you can determine the reasonableness of such a repair.
